Stroke is a “disease of disparities,” with racial and ethnic inequities in incidence, prevalence, treatment, and outcomes, and research is needed to identify structural or “upstream” interventions to address the problem, the American Heart Association says in a new scientific statement.

“There are enormous inequities in stroke care, which lead to significant gaps in functional outcomes after stroke for people from historically disenfranchised racial and ethnic groups, including Black, Hispanic, and Indigenous peoples,” writing group chair Amytis Towfighi, MD, professor of neurology, University of Southern California, Los Angeles, says in a news release.

“While research has historically focused on describing these inequities, it is critical to develop and test interventions to address them,” Dr. Towfighi adds.

The scientific statement was published online in the journal Stroke.

It follows a 2020 AHA presidential advisory that declared structural racism a fundamental driver of poor health and early death from heart disease and stroke.

Dr. Towfighi and colleagues reviewed the literature on interventions to address racial and ethnic inequities to identify gaps and areas for future research.

They note that various interventions have shown promise in reducing inequities across the stroke continuum of care.

For example, data suggest that careful attention to stroke preparedness among patients, caregivers, and emergency medical services can reduce inequities in getting people suspected of having a stroke to the emergency department quickly, with delivery of prompt treatment.

However, insufficient research attention has been paid to reducing inequities in rehabilitation, recovery, and social reintegration, the writing group says.

In addition, most studies have addressed patient-level factors, such as medication adherence, health literacy, and health behaviors, but not upstream social factors such as structural racism, housing, income, food security, and access to care, which also affect stroke incidence, care, and outcomes.

“Combating the effects of systemic racism will involve upstream interventions, including policy changes, place-based interventions, and engaging with the health care systems that serve predominantly historically disenfranchised populations and the communities they serve, understanding the barriers, and collaboratively developing solutions to address barriers,” the writing group says.

Further research is needed across the stroke continuum of care to tackle racial and ethnic inequities in stroke care and improve outcomes, they say.

“It’s critical for historically disenfranchised communities to participate in research so that researchers may collaborate in addressing the communities’ needs and concerns,” Bernadette Boden-Albala, DrPH, MPH, vice chair of the writing group, says in the news release.

“Opportunities include working with community stakeholder groups and community organizations to advocate for partnerships with hospitals, academic medical centers, local colleges and universities; or joining community advisory boards and volunteering with the American Heart Association,” Dr. Boden-Albala adds.

Dr. Towfighi encourages health care professionals to “think outside the ‘stroke box.’ Sustainable, effective interventions to address inequities will likely require collaboration with patients, their communities, policymakers, and other sectors.”

The scientific statement was prepared by the volunteer writing group on behalf of the AHA Stroke Council, the Council on Cardiovascular and Stroke Nursing, the Council on Cardiovascular Radiology and Intervention, the Council on Clinical Cardiology, the Council on Hypertension, the Council on the Kidney in Cardiovascular Disease, and the Council on Peripheral Vascular Disease.

The research had no commercial funding.

New mechanisms underlying Takotsubo syndrome, often dubbed “broken heart syndrome,” are suggested from hemodynamic studies, which could lead to new treatment strategies for the condition.

Takotsubo syndrome is a form of acute heart failure that mimics acute coronary syndromes, with troponin elevation and symptoms including chest pain and dyspnea, but without a culprit lesion on coronary angiography.

However, echocardiography shows the heart to be massively enlarged. The condition was named by Japanese researchers as the shape of the left ventricle resembles the Takotsubo fishing pot used to trap octopi.

The condition affects mainly older women and accounts for about 6% of female patients presenting with acute coronary syndrome symptoms. In around two-thirds of cases there is a triggering stress event which can be physical, such as an acute disease, or emotional, such as an argument or the sudden death of someone close, hence the term “broken heart syndrome.” The emotional stress triggering the syndrome can also be positive such as a birthday party or the birth of a grandchild.

“The mechanisms involved in Takotsubo syndrome are unknown. Because there is often a stress trigger it is believed that sympathetic activation causes a surge of catecholamine release, but that is not fully understood,” lead author of the current study, Thomas Stiermaier, MD, University Heart Center Lübeck (Germany), explained in an interview.

“We wanted to look more closely at the hemodynamic effects in the hearts of patients with Takotsubo syndrome to see if we could identify novel mechanisms contributing to the condition,” he added.

The aptly named Optimized Characterization of Takotsubo Syndrome by Obtaining Pressure Volume Loops (OCTOPUS) study was published online in the Journal of the American College of Cardiology.

For the study, the researchers used a conductance catheter inserted into the left ventricle of the heart to analyze pressure-volume relationships in 24 consecutive patients with Takotsubo syndrome and a control population of 20 participants without cardiovascular disease.

These pressure-volume loops are “the gold standard for direct, real-time assessment of systolic and diastolic cardiac function independent of loading conditions,” and “provide in-depth information regarding ventricular-arterial coupling and cardiac energetics and efficiency,” the authors wrote.

“These parameters comprise a considerable amount of information on cardiac performance and help to advance our understanding of cardiac physiology and its pathophysiological role in various conditions,” they noted, adding that this is believed to be the first comprehensive hemodynamic analysis in patients with Takotsubo syndrome using such invasive tracing of pressure-volume loops.

Results showed that Takotsubo syndrome is associated with a severely impaired cardiac contractility and a shortened systolic period. In response, the heart compensates by increasing left ventricular end diastolic volume to preserve the stroke volume.

Diastolic function is characterized by prolonged active relaxation but unaltered passive elastic properties. The analysis of myocardial energetics revealed an inefficient system with increased potential and decreased kinetic energy (stroke work).

“These are new and important findings,” Dr. Stiermaier said, adding that these hemodynamic changes give clues as to the underlying mechanisms at play in Takotsubo syndrome, as well as possible treatment strategies that could be investigated.  

“Taking all this information together, we believe that it is likely that decreased phosphorylation of myofilament proteins – which may be caused by some kind of disturbance in calcium metabolism – may partially account for the impaired contractility and shortened systolic period seen in Takotsubo syndrome,” he commented.

The researchers suggested that Takotsubo syndrome may therefore be treated with medications such as omecamtiv (a drug that increases systolic duration) or the calcium sensitizer levosimendan, which improves contractility, possibly in combination with beta-blockers to protect against the intense adrenergic activation.

They noted that several studies have reported the use of levosimendan in Takotsubo syndrome and have suggested positive effects by accelerating recovery of ventricular function. But they added that prospective data are lacking, and, to their knowledge, omecamtiv has not been tested in Takotsubo syndrome.

“We need to clearly identify the mechanism involved in these changes at the cellular level, and then test these medications to see if they can help prevent or reverse the hemodynamic changes seen in Takotsubo syndrome,” Dr. Stiermaier said.

He explained that the contractile abnormalities in Takotsubo syndrome are transient and generally normalize after a few weeks or months, but while systolic function may appear normal in the long term there are other more subtle changes that can persist, and these patients have an increased rate of cardiovascular events, compared with the healthy population over the long term.

However, because Takotsubo syndrome patients generally have a high rate of other comorbidities, it is not known whether their increased event rate is caused by the syndrome or by these other comorbidities.

While some patients with Takotsubo syndrome have a mild disease course and a good prognosis, others have more complications, with around 10%-15% going on to develop severe disease with cardiogenic shock or pleural effusion, Dr. Stiermaier noted.

“These patients have a bad prognosis. Our aim is to try to identify the patients who are at high risk of these complications and treat them early to prevent cardiogenic shock and pleural effusion from developing,” he said. “We are hopeful that by identifying the hemodynamic changes occurring in Takotsubo syndrome we can figure out the mechanisms involved and give medications in the acute setting to prevent the complications that can arise down the road.”
 

Mechanisms ‘appealing but speculative’

In an editorial (J Am Coll Cardiol. 2023 May;81[20]:1992-5), Jorge Salamanca, MD, and Fernando Alfonso, MD, Hospital Universitario de La Princesa, Madrid, described this new study as “an important piece of research, providing a careful, systematic, and comprehensive set of sophisticated invasive hemodynamic data that shed new light on our understanding of this unique clinical entity.”

They said the researchers have provided “robust data on the acute hemodynamic behavior of the left ventricle in patients with Takotsubo syndrome that clearly advance the field but also raise new questions.”

But the editorialists cautioned that the hypotheses of the potential mechanisms linking a molecular basis for the metabolic dysregulation, resulting in increased potential energy coupled with a decreased kinetic energy, “are appealing but largely speculative.”

“Whether these hemodynamic findings could be the foundation and would support the use of novel and attractive drugs in Takotsubo syndrome, remains unsettled and can only be considered as hypothesis generating,” they wrote.

“Further studies are required to elucidate factors associated with a more severe hemodynamic derangement and to devise therapeutic strategies helping to rapidly restore an efficient left ventricular function in these challenging patients,” they concluded. 

The study authors and the editorialists reported no relevant financial relationships.

Women who experienced gestational hypertension or preeclampsia are at increased risk of developing nonischemic heart failure (HF) and especially ischemic HF over the next decade or two, an observational study suggests.

The risks were most pronounced, jumping more than sixfold in the case of ischemic HF, during the first 6 years after the pregnancy. They then receded to plateau at a lower, still significantly elevated level of risk that persisted even years later, in the analysis of women in a Swedish medical birth registry.

Jupiterimages/Thinkstock.com

The case-matching study compared women with no history of cardiovascular (CV) disease and a first successful pregnancy during which they either developed or did not experience gestational hypertension or preeclampsia.

It’s among the first studies to explore the impact of pregnancy-induced hypertensive disease on subsequent HF risk separately for both ischemic and nonischemic HF and to find that the severity of such risk differs for the two HF etiologies, according to a report published in JACC: Heart Failure.

The adjusted risk for any HF during a median of 13 years after the pregnancy rose 70% for those who had developed gestational hypertension or preeclampsia. Their risk of nonischemic HF went up 60%, and their risk of ischemic HF more than doubled.

Hypertensive disorders of pregnancy “are so much more than short-term disorders confined to the pregnancy period. They have long-term implications throughout a lifetime,” lead author Ängla Mantel, MD, PhD, said in an interview.

Obstetric history doesn’t figure into any formal HF risk scoring systems, observed Dr. Mantel of Karolinska Institutet, Stockholm. Still, women who develop gestational hypertension, preeclampsia, or other pregnancy complications “should be considered a high-risk population even after the pregnancy and monitored for cardiovascular risk factors regularly throughout life.”

In many studies, she said, “knowledge of women-specific risk factors for cardiovascular disease is poor among both clinicians and patients.” The current findings should help raise awareness about such obstetric risk factors for HF, “especially” in patients with HF with preserved ejection fraction (HFpEF), which isn’t closely related to a number of traditional CV risk factors.

Even though pregnancy complications such as gestational hypertension and preeclampsia don’t feature in risk calculators, “they are actually risk enhancers per the 2019 primary prevention guidelines,” Natalie A. Bello, MD, MPH, who was not involved in the current study, said in an interview.

“We’re working to educate physicians and cardiovascular team members to take a pregnancy history” for risk stratification of women in primary prevention,” said Dr. Bello, director of hypertension research at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles.

The current study, she said, “is an important step” for its finding that hypertensive disorders of pregnancy are associated separately with both ischemic and nonischemic HF.

She pointed out, however, that because the study excluded women with peripartum cardiomyopathy, a form of nonischemic HF, it may “underestimate the impact of hypertensive disorders on the short-term risk of nonischemic heart failure.” Women who had peripartum cardiomyopathy were excluded to avoid misclassification of other HF outcomes, the authors stated.

Also, Dr. Bello said, the study’s inclusion of patients with either gestational hypertension or preeclampsia may complicate its interpretation. Compared with the former condition, she said, preeclampsia “involves more inflammation and more endothelial dysfunction. It may cause a different impact on the heart and the vasculature.”

In the analysis, about 79,000 women with gestational hypertension or preeclampsia were identified among more than 1.4 million primiparous women who entered the Swedish Medical Birth Register over a period of about 30 years. They were matched with about 396,000 women in the registry who had normotensive pregnancies.

Excluded, besides women with peripartum cardiomyopathy, were women with a prepregnancy history of HF, hypertension, ischemic heart disease, atrial fibrillation, or valvular heart disease.

Hazard ratios (HRs) for HF, ischemic HF, and nonischemic HF were significantly elevated over among the women with gestational hypertension or preeclampsia compared to those with normotensive pregnancies:

• Any HF: HR, 1.70 (95% confidence interval [CI], 1.51-1.91)
• Nonischemic HF: HR, 1.60 (95% CI, 1.40-1.83)
• Ischemic HF: HR, 2.28 (95% CI, 1.74-2.98)

The analyses were adjusted for maternal age at delivery, year of delivery, prepregnancy comorbidities, maternal education level, smoking status, and body mass index.

Sharper risk increases were seen among women with gestational hypertension or preeclampsia who delivered prior to gestational week 34:

• Any HF: HR, 2.46 (95% CI, 1.82-3.32)
• Nonischemic HF: HR, 2.33 (95% CI, 1.65-3.31)
• Ischemic HF: HR, 3.64 (95% CI, 1.97-6.74)

Risks for HF developing within 6 years of pregnancy characterized by gestational hypertension or preeclampsia were far more pronounced for ischemic HF than for nonischemic HF:

• Any HF: HR, 2.09 (95% CI, 1.52-2.89)
• Nonischemic HF: HR, 1.86 (95% CI, 1.32-2.61)
• Ischemic HF: HR, 6.52 (95% CI, 2.00-12.34).

The study couldn’t directly explore potential mechanisms for the associations between pregnancy-induced hypertensive disorders and different forms of HF, but it may have provided clues, Dr. Mantel said.

The hypertensive disorders and ischemic HF appear to share risk factors that could lead to both conditions, she noted. Also, hypertension itself is a risk factor for ischemic heart disease.

In contrast, “the risk of nonischemic heart failure might be driven by other factors, such as the inflammatory profile, endothelial dysfunction, and cardiac remodeling induced by preeclampsia or gestational hypertension.”

Those disorders, moreover, are associated with cardiac structural changes that are also seen in HFpEF, Dr. Mantel said. And both HFpEF and preeclampsia are characterized by systemic inflammation and endothelial dysfunction.

“These pathophysiological similarities,” she proposed, “might explain the link between pregnancy-induced hypertensive disorder and HFpEF.”

Women who experienced gestational hypertension or preeclampsia are at increased risk of developing nonischemic heart failure (HF) and especially ischemic HF over the next decade or two, an observational study suggests.

The risks were most pronounced, jumping more than sixfold in the case of ischemic HF, during the first 6 years after the pregnancy. They then receded to plateau at a lower, still significantly elevated level of risk that persisted even years later, in the analysis of women in a Swedish medical birth registry.

The case-matching study compared women with no history of cardiovascular (CV) disease and a first successful pregnancy during which they either developed or did not experience gestational hypertension or preeclampsia.

It’s among the first studies to explore the impact of pregnancy-induced hypertensive disease on subsequent HF risk separately for both ischemic and nonischemic HF and to find that the severity of such risk differs for the two HF etiologies, according to a report published in JACC: Heart Failure.

The adjusted risk for any HF during a median of 13 years after the pregnancy rose 70% for those who had developed gestational hypertension or preeclampsia. Their risk of nonischemic HF went up 60%, and their risk of ischemic HF more than doubled.

Hypertensive disorders of pregnancy “are so much more than short-term disorders confined to the pregnancy period. They have long-term implications throughout a lifetime,” lead author Ängla Mantel, MD, PhD, said in an interview.

Obstetric history doesn’t figure into any formal HF risk scoring systems, observed Dr. Mantel of Karolinska Institutet, Stockholm. Still, women who develop gestational hypertension, preeclampsia, or other pregnancy complications “should be considered a high-risk population even after the pregnancy and monitored for cardiovascular risk factors regularly throughout life.”

In many studies, she said, “knowledge of women-specific risk factors for cardiovascular disease is poor among both clinicians and patients.” The current findings should help raise awareness about such obstetric risk factors for HF, “especially” in patients with HF with preserved ejection fraction (HFpEF), which isn’t closely related to a number of traditional CV risk factors.

Even though pregnancy complications such as gestational hypertension and preeclampsia don’t feature in risk calculators, “they are actually risk enhancers per the 2019 primary prevention guidelines,” Natalie A. Bello, MD, MPH, who was not involved in the current study, said in an interview.

“We’re working to educate physicians and cardiovascular team members to take a pregnancy history” for risk stratification of women in primary prevention,” said Dr. Bello, director of hypertension research at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles.

The current study, she said, “is an important step” for its finding that hypertensive disorders of pregnancy are associated separately with both ischemic and nonischemic HF.

She pointed out, however, that because the study excluded women with peripartum cardiomyopathy, a form of nonischemic HF, it may “underestimate the impact of hypertensive disorders on the short-term risk of nonischemic heart failure.” Women who had peripartum cardiomyopathy were excluded to avoid misclassification of other HF outcomes, the authors stated.

Also, Dr. Bello said, the study’s inclusion of patients with either gestational hypertension or preeclampsia may complicate its interpretation. Compared with the former condition, she said, preeclampsia “involves more inflammation and more endothelial dysfunction. It may cause a different impact on the heart and the vasculature.”

In the analysis, about 79,000 women with gestational hypertension or preeclampsia were identified among more than 1.4 million primiparous women who entered the Swedish Medical Birth Register over a period of about 30 years. They were matched with about 396,000 women in the registry who had normotensive pregnancies.

Excluded, besides women with peripartum cardiomyopathy, were women with a prepregnancy history of HF, hypertension, ischemic heart disease, atrial fibrillation, or valvular heart disease.

Hazard ratios (HRs) for HF, ischemic HF, and nonischemic HF were significantly elevated over among the women with gestational hypertension or preeclampsia compared to those with normotensive pregnancies:

• Any HF: HR, 1.70 (95% confidence interval [CI], 1.51-1.91)
• Nonischemic HF: HR, 1.60 (95% CI, 1.40-1.83)
• Ischemic HF: HR, 2.28 (95% CI, 1.74-2.98)

The analyses were adjusted for maternal age at delivery, year of delivery, prepregnancy comorbidities, maternal education level, smoking status, and body mass index.

Sharper risk increases were seen among women with gestational hypertension or preeclampsia who delivered prior to gestational week 34:

• Any HF: HR, 2.46 (95% CI, 1.82-3.32)
• Nonischemic HF: HR, 2.33 (95% CI, 1.65-3.31)
• Ischemic HF: HR, 3.64 (95% CI, 1.97-6.74)

Risks for HF developing within 6 years of pregnancy characterized by gestational hypertension or preeclampsia were far more pronounced for ischemic HF than for nonischemic HF:

• Any HF: HR, 2.09 (95% CI, 1.52-2.89)
• Nonischemic HF: HR, 1.86 (95% CI, 1.32-2.61)
• Ischemic HF: HR, 6.52 (95% CI, 2.00-12.34).

The study couldn’t directly explore potential mechanisms for the associations between pregnancy-induced hypertensive disorders and different forms of HF, but it may have provided clues, Dr. Mantel said.

The hypertensive disorders and ischemic HF appear to share risk factors that could lead to both conditions, she noted. Also, hypertension itself is a risk factor for ischemic heart disease.

In contrast, “the risk of nonischemic heart failure might be driven by other factors, such as the inflammatory profile, endothelial dysfunction, and cardiac remodeling induced by preeclampsia or gestational hypertension.”

Those disorders, moreover, are associated with cardiac structural changes that are also seen in HFpEF, Dr. Mantel said. And both HFpEF and preeclampsia are characterized by systemic inflammation and endothelial dysfunction.

“These pathophysiological similarities,” she proposed, “might explain the link between pregnancy-induced hypertensive disorder and HFpEF.”

A novel artificial intelligence (AI) algorithm shows promise for estimating left ventricular ejection function (LVEF) using routinely obtained left coronary artery angiogram videos, a new study suggests.

In the test dataset, the video-based algorithm, called a deep neural network (DNN), discriminated reduced LVEF (< 40%) with an area under the receiver operating characteristic curve of 0.911.

In the external validation dataset, the DNN discriminated reduced LVEF with an AUROC of 0.906. However, the DNN tended to overestimate low LVEFs and to underestimate high LVEFs.

“We know the findings will be unexpected for cardiologists who don’t typically expect to get an estimate of systolic function or pump function just from an angiogram,” principal investigator Geoffrey H. Tison, MD, of the University of California, San Francisco, said in an interview.

In fact, he noted, “one of the challenges we face is a lack of trust by the health care community. They may not understand what drives the predictions behind our models. We have to translate that information in such a way that physicians trust that the algorithm is using the right features from the data they feed in to make the predictions.”

To help bolster that trust, “we display the ‘Model Facts,’ a nutrition-style label that describes how we train the algorithm, how it was validated, and the inclusion and exclusion criteria,” added lead author Robert Avram, MD, of the University of Montreal.

Model Facts is a safeguard against inappropriate use of the algorithm, Dr. Avram said. For example, if the algorithm was trained on patients between the ages of 40 and 90 and a clinician fed in data for a 35-year-old, a pop-up would appear warning the physician that the data being inputted are different from the data the algorithm was trained and validated on, and so any prediction “should be taken with a grain of salt.”

The study was published online in JAMA Cardiology.
 

Additional procedure

LVEF can be determined before coronary angiography with transthoracic echocardiography, but that is not always available, particularly for patients being seen emergently for acute coronary syndromes, the researchers wrote. LVEF can also be assessed using left ventriculography, an additional procedure that requires insertion of a pigtail catheter into the left ventricle and injection of more contrast and longer radiation exposure.

“Novel methods to assess LVEF at the point of care during coronary angiography would expand the available options to perform this important physiologic determination,” they wrote. “Video-based deep neural networks can learn subtle patterns from medical data to accomplish certain tasks beyond what physicians can achieve with that data, providing an opportunity to assess cardiac systolic function in real time from standard angiographic images without additional cost or procedures.”

The investigators conducted a cross-sectional study using UCSF patient data from 2012 to 2019. Data were randomly categorized into training, development, and test datasets.

External validation data were obtained from the University of Ottawa Heart Institute.

All adult patients who received a coronary angiogram and a transthoracic echocardiogram (TTE) within 3 months before or 1 month after receiving the angiogram were included.

A total of 4,042 angiograms with corresponding TTE LVEF from 3,679 UCSF patients were included in the analysis. The mean age of the patients was 64.3 years, and 65% were men.

The researchers’ video-based DNN, called CathEF, was used to discriminate reduced LVEF and to predict a continuous LVEF percentage from standard angiogram videos of the left coronary artery.

In the UCSF test dataset, CathEF discriminated reduced LVEF with an AUROC of 0.911; the diagnostic odds ratio for reduced LVEF was 22.7.

Furthermore, the CathEF-predicted that LVEF had a mean absolute error (MAE) of 8.5%, compared with TTE LVEF.

The CathEF-predicted LVEF differed 5% or less in comparison with the TTE LVEF in 38% of the test dataset studies; however, differences greater than 15% were seen in 15.2% of cases.

In the external validation, CathEF discriminated reduced LVEF with an AUROC of 0.906 and an MAE of 7%.

CathEF performance was consistent irrespective of patient characteristics, including sex, body mass index, low estimated glomerular filtration rate (< 45), acute coronary syndromes, obstructive coronary artery disease, and left ventricular hypertrophy.

However, as noted, it tended to overestimate low LVEFs and to underestimate high LVEFs.

“Further research can improve accuracy and reduce the variability of DNNs to maximize their clinical utility,” the authors concluded.

A validation study is underway at the Montreal Heart Institute, and similar studies are planned at UCSF and McGill University, Dr. Tison said. “We expect to present preliminary findings at medical conferences either before the end of the year or maybe for the American College of Cardiology meeting in March 2024.”
 

Potentially improved outcomes

In a comment, Alfonso H. Waller, MD, a member of the American College of Cardiology’s Imaging Council and director of cardiac imaging at New Jersey Medical School, Newark, said that, “at some centers, in patients presenting with an acute ST-segment elevation myocardial infarction, some argue that assessment of myocardial and valvular function with [left ventriculography] grams may provide important prognostic information and in part may help guide the management of the patient.

“Therefore, this novel approach may provide information that is not usually available without performing a classic LV gram ... [and] may lead to improved delivery of care, earlier therapies, and potentially improved outcomes and quality of life.”

If the technology is available in real time, “it could enable real-time, dynamic assessment of cardiac function during coronary angiography, which may be particularly helpful in acute STEMI cases where baseline cardiac function and renal function may be unknown and additional contrast may be detrimental,” he said.

However, patients who might benefit most from the technology are those with severely reduced LVEF, “and unfortunately, the LVEF may be overestimated in this group,” he said.

Dr. Waller also noted that the model was developed using echocardiograms obtained 3 months before or up to 1 month after the angiogram, during which time “LVEF may change significantly. Typically, if someone presents with an acute coronary syndrome, there can be myocardial stunning, which can lead to regional wall motion abnormalities and lowering of LVEF.”

The validation study is evaluating patients with acute coronary syndrome for whom an echocardiogram was performed within 48 hours of the angiogram, he added.

The study was supported by grants from the Fonds de la Recherche en Santé du Québec, the Montreal Heart Institute Research Centre, the Montreal Heart Institute Foundation, the Des Groseillers-Bérard Research Chair, the National Institutes of Health, and the Heart and Stroke Foundation of Ontario. Dr. Tison, Dr. Avram, and Dr. Waller disclosed no relevant financial relationships.

Hyperbaric oxygen therapy (HBOT) increased markers of heart function in a small randomized, controlled trial of patients with long COVID.

Patients with reduced left ventricular global longitudinal strain (GLS) at baseline who received HBOT had a significant increase in GLS, compared with those who received sham treatment.

GLS is a measure of systolic function that is thought to be a predictor of heart failure–related outcomes.

The study also showed that global work efficiency (GWE) and the global work index (GWI) increased in HBOT-treated patients, though not significantly.

“HBOT is an effective treatment for diabetic foot ulcers, decompression sickness in divers, and other conditions, such as cognitive impairment after stroke,” Marina Leitman, MD, of the Sackler School of Medicine, Tel Aviv, said in an interview. Her team also studied HBOT in asymptomatic older patients and found that the treatment seemed to improve left ventricular end systolic function.

“We should open our minds to thinking about this treatment for another indication,” she said. “That is the basis of precision medicine. We have this treatment and know it can be effective for cardiac pathology.

“Now we can say that post-COVID syndrome patients probably should be evaluated with echocardiography and GLS, which is the main parameter that showed improvement in our study,” she added. “If GLS is below normal values, these patients can benefit from HBOT, although additional research is needed to determine the optimal number of sessions.”

Dr. Leitman presented the study at the European Association of Cardiovascular Imaging 2023, a scientific congress of the European Society of Cardiology.
 

Biomarker changes

The study enrolled 60 hospitalized and nonhospitalized post-COVID syndrome patients with ongoing symptoms for at least 3 months after having mild to moderate symptomatic COVID-19.

Participants were randomized to receive HBOT or a sham procedure five times per week for 8 weeks, for a total of 40 sessions. They underwent echocardiography at baseline and 1-3 weeks after the final session to assess GLS.

The HBOT group received 100% oxygen through a mask at a pressure of two atmospheres for 90 minutes, with 5-minute air breaks every 20 minutes.

The sham group received 21% oxygen by mask at one atmosphere for 90 minutes.

At baseline, 29 participants (48%) had reduced GLS, despite having a normal ejection fraction, Dr. Leitman said. Of those, 16 (53%) were in the HBOT group and 13 (43%) were in the sham group.

The average GLS at baseline across all participants was –17.8%; a normal value is about –20%.

In the HBOT group, GLS increased significantly from –17.8% at baseline to –20.2% after HBOT. In the sham group, GLS was –17.8% at baseline and –19.1% at the end of the study, with no statistically significant difference between the two measurements.

In addition, GWE increased overall after HBOT from 96.3 to 97.1.

Dr. Leitman’s poster showed GLS and myocardial work indices before and after HBOT in a 45-year-old patient. Prior to treatment, GLS was –19%; GWE was 96%; and GWI was 1,833 mm Hg.

After HBOT treatment, GLS was –22%; GWE, 98%; and GWI, 1,911 mm Hg.
 

Clinical relevance unclear

Scott Gorenstein, MD, associate professor in the department of surgery and medical director of wound care and hyperbaric medicine at NYU Langone–Long Island, New York, commented on the study for this news organization.

“The approach certainly warrants studying, but the benefit is difficult to assess,” he said. “We still don’t understand the mechanism of long COVID, so it’s difficult to go from there to say that HBOT will be an effective therapy.”

That said, he added, “This is probably the best study I’ve seen in that it’s a randomized controlled trial, rather than a case series.”

Nevertheless, he noted, “We have no idea from this study whether the change in GLS is clinically relevant. As a clinician, I can’t now say that HBOT is going to improve heart failure secondary to long COVID. We don’t know whether the participants were New York heart failure class 3 or 4, for example, and all of a sudden went from really sick to really good.”

“There are many interventions that may change markers of cardiac function or inflammation,” he said. “But if they don’t make a difference in quantity or quality of life, is the treatment really valuable?”

Dr. Gorenstein said he would have no problem treating a patient with mild to moderate COVID-related heart failure with HBOT, since his own team’s study conducted near the outset of the pandemic showed it was safe. “But HBOT is an expensive treatment in the U.S. and there still are some risks and side effects, albeit very, very low.”

The study received no funding. Dr. Leitman and Dr. Gorenstein have disclosed no relevant financial relationships.

Hyperbaric oxygen therapy (HBOT) increased markers of heart function in a small randomized, controlled trial of patients with long COVID.

Patients with reduced left ventricular global longitudinal strain (GLS) at baseline who received HBOT had a significant increase in GLS, compared with those who received sham treatment.

GLS is a measure of systolic function that is thought to be a predictor of heart failure–related outcomes.

The study also showed that global work efficiency (GWE) and the global work index (GWI) increased in HBOT-treated patients, though not significantly.

“HBOT is an effective treatment for diabetic foot ulcers, decompression sickness in divers, and other conditions, such as cognitive impairment after stroke,” Marina Leitman, MD, of the Sackler School of Medicine, Tel Aviv, said in an interview. Her team also studied HBOT in asymptomatic older patients and found that the treatment seemed to improve left ventricular end systolic function.

“We should open our minds to thinking about this treatment for another indication,” she said. “That is the basis of precision medicine. We have this treatment and know it can be effective for cardiac pathology.

Disappointment – “I failed this exam, my life is ruined” or regret – “I am getting a divorce, I wasted so much of my life.” Patients present with a wide variety of complaints that can be understood as a form of death anxiety.

Fundamentally, patients come to see us to understand and explain their lives. One can reinterpret this as a patient asking, “If I died today, would my life have been good enough?” or “When I die, how will I look back at this moment in time and judge the choices I made?”

Other patients come to us attempting to use the same maladaptive defenses that did not serve them well in the past in the hopes of achieving a new outcome that will validate their lives. While it may be understandable that a child dissociates when facing abuse, hoping that this defense mechanism – as an adult – will work, it is unlikely to be fruitful and will certainly not validate or repair the past. This hope to repair one’s past can be interpreted as a fear of death – “I cannot die without correcting this.” This psychic conflict can intensify if one does not adopt a more adaptive understanding of his or her life.

Death anxiety is the feeling associated with the finality of life. Not only is life final, but a constant reminder of that fact is the idea that any one moment is final. Other than in science fiction, one cannot return to a prior moment and repair the past in the hope of a better future. Time goes only in one direction and death is the natural outcome of all life.

Death may have some evolutionary purpose that encourages the promotion of newer and more fitter genes, but one doesn’t have to consider its origin and reason to admit death’s constancy throughout humanity. People die and that is an anxiety-provoking fact of life. Death anxiety can feel especially tangible in our connected world. In a world of constant news, it can feel – for many people – that if your house wasn’t displaced because of global warming or that you are not a war refugee, you don’t deserve to be seen and heard.

This can be a particularly strong feeling for and among physicians, who don’t think that the mental health challenges generated by their own tough circumstances deserve to be labeled a mental disorder, so they designate themselves as having “burnout”¹ – as they don’t deserve the sympathy of having the clinically significant impairments of “depression.” Our traumas don’t seem important enough to deserve notice, and thus we may feel like we could die without ever having truly mattered.

This can also be applied in the reverse fashion. Certain individuals, like celebrities, live such extravagant lives that our simpler achievements can feel futile in comparison. While the neighbor’s grass has always felt greener, we are now constantly exposed to perfectly manicured lawns on social media. When compounded, the idea that our successes and our pains are both simultaneously irrelevant can lead one to have very palpable death anxiety – my life will never matter if none of the things I do matter, or my life will never matter because I will never achieve the requisite number of “likes” or “views” on social media required to believe that one’s life was worth living.

A way of alleviating death anxiety can be through the concept of legacy, or what we leave behind. How will people remember me? Will people remember me, or will I disappear like a shadow into the distant memory of my near and dear ones? The idea of being forgotten or lost to memory is intolerable to some and can be a strong driving force to “make a name” for oneself. For those who crave fame, whether a celebrity or a generous alumnus, part of this is likely related to remaining well known after death. After all, one can argue that you are not truly dead as long as you continue to live in the memory and/or genes of others.

Legacy thus serves as a form of posthumous transitional object; a way of calming our fears about how we will be remembered. For many, reconciling their feelings towards their legacy is an avenue to tame death anxiety.
 

A case study

The case of Mr. B illustrates this. As a 72-year-old male with a long history of generalized anxiety, he once had a nightmare as a child, similar to the plot of Sleeping Beauty. In his dream, he walks up a spiral staircase in a castle and touches the spindle on a spinning wheel, thus ending his life. The dream was vivid and marked him.

His fear of death has subsequently reared its head throughout his life. In more recent years, he has suffered from cardiovascular disease. Although he is now quite stable on his current cardiac medications, he is constantly fearful that he will experience a cardiac event while asleep and suddenly die. He is so anxious about not waking up in the morning that falling asleep is nearly impossible.

Mr. B is single, with no close family besides a sister who lives in another state. He has a dog and few friends. He worries about what will happen to his dog if he doesn’t wake up in the morning, but perhaps most distressing to him is “there’s so much left for me to do, I have so much to write!” As an accomplished author, he continues to write, and hopes to publish many more novels in his lifetime. It is unsurprising that someone without a strong social network may fear death and feel pressured to somehow make a mark on the world before the curtain falls. It is scary to think that even without us, life goes on.

By bringing to Mr. B’s attention that his ever-present anxiety is rooted in fear of death, he was able to gain more insight into his own defensive behaviors. By confronting his death anxiety and processing his definition of a life well lived together in therapy, he’s acknowledged his lack of social connection as demoralizing, and has made significant strides to remedy this. He’s been able to focus on a more fulfilling life day to day, with less emphasis on his to-do list and aspirations. Instead, he’s connected more with his faith and members of his church. He’s gotten close to several neighbors and enjoys long dinners with them on his back patio.

At a recent meeting, he confessed that he feels “lighter” and not as fearful about sudden cardiac death, and thus has noticed that his overall anxiety has diminished greatly. He concluded that experiencing meaningful relationships in the present moment would give him greater joy than spending his remaining time engaged in preserving a future identity for himself. It seems elementary, but if we look within, we may find that we all suffer similarly: How much of our daily actions, thoughts, and fears are tied to the looming threat of death?
 

Conclusion

While modern psychiatry continues to advance with better understandings of our neurobiology, improved knowledge of pathophysiological processes of mental illness, and expanding discovery of novel pharmacotherapeutics, the modern psychiatrist should not forget fundamental truths of behavior and humanity that were once the staple of psychiatry.

Death anxiety is one of those truths; it is the ultimate stressor that we will all face and should be regular study and practice for psychiatrists. In this article, we explored some of those facets most meaningful to us but recommend you expand your study to the many more available.

Death anxiety is a constant reminder that life is final, and it is natural to feel anxious when thinking about it. Patients often come to physicians seeking validation of their lives or trying to use the same maladaptive defense mechanisms that did not serve them well in the past to achieve a better outcome.

In today’s world, death anxiety can feel palpable due to the constant exposure to global news and social media that can make us feel irrelevant. However, legacy, or what we leave behind, can serve as a way to alleviate death anxiety. For many, reconciling their feelings toward their legacy is an avenue to tame death anxiety. Therapy can help individuals gain insight into their defensive behaviors and process their definition of a life well lived. By focusing on a life worth living, individuals can alleviate their death anxiety and gain a sense of fulfillment.

He worries about what will happen to his dog if he doesn’t wake up in the morning, but perhaps most distressing to him is “there’s so much left for me to do, I have so much to write!” As an accomplished author, he continues to write, and hopes to publish many more novels in his lifetime. It is unsurprising that someone without a strong social network may fear death and feel pressured to somehow make a mark on the world before the curtain falls. It is scary to think that even without us, life goes on.

By bringing to Mr. B’s attention that his ever-present anxiety is rooted in fear of death, he was able to gain more insight into his own defensive behaviors. By confronting his death anxiety and processing his definition of a life well lived together in therapy, he’s acknowledged his lack of social connection as demoralizing, and has made significant strides to remedy this. He’s been able to focus on a more fulfilling life day to day, with less emphasis on his to-do list and aspirations. Instead, he’s connected more with his faith and members of his church. He’s gotten close to several neighbors and enjoys long dinners with them on his back patio.

At a recent meeting, he confessed that he feels “lighter” and not as fearful about sudden cardiac death, and thus has noticed that his overall anxiety has diminished greatly. He concluded that experiencing meaningful relationships in the present moment would give him greater joy than spending his remaining time engaged in preserving a future identity for himself. It seems elementary, but if we look within, we may find that we all suffer similarly: How much of our daily actions, thoughts, and fears are tied to the looming threat of death?
 

Conclusion

While modern psychiatry continues to advance with better understandings of our neurobiology, improved knowledge of pathophysiological processes of mental illness, and expanding discovery of novel pharmacotherapeutics, the modern psychiatrist should not forget fundamental truths of behavior and humanity that were once the staple of psychiatry.

Death anxiety is one of those truths; it is the ultimate stressor that we will all face and should be regular study and practice for psychiatrists. In this article, we explored some of those facets most meaningful to us but recommend you expand your study to the many more available.

Death anxiety is a constant reminder that life is final, and it is natural to feel anxious when thinking about it. Patients often come to physicians seeking validation of their lives or trying to use the same maladaptive defense mechanisms that did not serve them well in the past to achieve a better outcome.

In today’s world, death anxiety can feel palpable due to the constant exposure to global news and social media that can make us feel irrelevant. However, legacy, or what we leave behind, can serve as a way to alleviate death anxiety. For many, reconciling their feelings toward their legacy is an avenue to tame death anxiety. Therapy can help individuals gain insight into their defensive behaviors and process their definition of a life well lived. By focusing on a life worth living, individuals can alleviate their death anxiety and gain a sense of fulfillment.

The past few years have seen major transformations in the way health care websites operate and interact with patients. To stay competitive, it is important to ensure that your website is adapting to this changing environment, and that it continues adapting as future changes further impact its performance and ranking.

In mid-2018, a major Google algorithm change, known to the IT community as the “Medic Update,” significantly changed search criteria for most health and wellness websites. Another big update went live in late 2021. Websites that have not evolved with these changes have dropped in search rankings and provide a poorer user experience all around.

Many potential patients are searching for your services online, so your website cannot be an afterthought. Not only does it need to be designed with your target audience in mind, but it is also important to consider the metrics Google and other search engines now use when assessing the quality of your website so that patients will find it in the first place.

Here are some features that you (or your website company) need to prioritize to keep your site current and atop search results in 2023 and beyond.

Begin with an understandable URL. Search engines use URLs to determine how well your site, or a portion of it, matches search criteria. URLs also need to make sense to searchers, especially when they link specific areas of expertise (more on that in a minute). For example, a URL like “jonesdermatology.com/?p=89021” is meaningless to anyone except programmers; but “jonesdermatology.com/psoriasistreatments” obviously leads to a page about psoriasis treatments. Search engines look for not only the most relevant, but also the most helpful and user-friendly answers to a user’s query.

Incidentally, if the URL for your site is not your own name, you should register your name as a separate domain name – even if you never use it – to be sure that a trickster or troll, or someone with the same name but a bad reputation, doesn’t get it.

Continue with a good meta description. That’s the grayish text that follows the title and URL in search results. Searchers will read it to confirm that your site is what they seek, so make sure it describes exactly what you do, including any areas of special expertise.

Make your practice approachable with photos. New patients are more comfortable when they know what you look like, so real photos of you and your staff are always more effective than stock photos of models. Photos or a video tour of your office will reassure prospective patients that they will be visiting a clean, modern, professional facility.

Describe your principal services in detail. You never know which specific service a prospective patient is searching for, so describe everything you offer. Don’t try to summarize everything on a single page; relevance is determined by how deeply a topic is covered, so each principal service should have a detailed description on its own page. Not only will your skills become more visible to search engines, but you can also use the space to enumerate your qualifications and expertise in each area. Whenever possible, write your descriptions in question-and-answer form. Searchers tend to ask questions (“what is the best ... ?”), particularly in voice searches. Search engines increasingly value sites that ask and answer common questions.

Make your site interactive. “Interactivity” is a major buzzword in modern search engine parlance. Once searchers make an appointment, they stop searching. If they have to wait until the next day to call your office, they may keep looking – and might find a competitor with online scheduling. HIPAA-compliant chatbots, secure messaging, and online patient portals to access medical records, lab results, and other important information will also set your site apart.

Testimonials are essential. Amazon.com taught us that candid reviews from customers go a long way toward building the trust necessary to buy products and services, and nowhere is that truer than for medical services. According to one study, when it comes to finding a doctor, 88% of people trust online reviews as much as a personal recommendation. Loyal patients will be happy to write you glowing reviews; feature them prominently.

How does your site look on small screens? More than half of all searches are now made on smartphones, so the more mobile-friendly your site is, the higher it will be ranked. Prospective patients who are forced to scroll forever, or zoom in to tap a link, are likely to become frustrated and move on. Mobile searchers prefer sites that provide the best experience for the least amount of effort, and rankings tend to reflect that preference.

Time-in-range (TIR) readings from a continuous glucose monitor (CGM) complemented hemoglobin A1c readings and provided a more complete picture of glucose control in patients with type 2 diabetes taking basal insulin, in a post hoc analysis of the SWITCH PRO clinical trial.

TIR was inversely related to A1c, with the strongest correlation following treatment intensification.

However, “there was a wide scatter of data, indicating that TIR (and other metrics) provides information about glycemic control that cannot be discerned from A1c alone, and which at least complements it,” Ronald M. Goldenberg, MD, from LMC Diabetes & Endocrinology in Thornhill, Ont., and colleagues write in their article published in Diabetes Therapy.

Other work has shown that more than a third of people with type 2 diabetes are not achieving the internationally recommended A1c target of < 7% to 8.5%, they note.

When used with A1c, CGM data – such as TIR, time below range (TBR), and time above range (TAR) – “provide a more complete picture of glucose levels throughout the day and night,” they write.

“This may help empower people with diabetes to better manage their condition, giving them practical insights into the factors driving daily fluctuations in glucose levels, such as diet, exercise, insulin dosage, and insulin timing,” they add. “These metrics may also be used to inform treatment decisions by health care professionals.”

“Ultimately,” the researchers conclude, “it is hoped that the use of these new metrics should lead to an improved quality of glycemic control and, in turn, to a reduction in the number of diabetes-related complications.”
 

‘Important study’

Invited to comment, Celeste C. Thomas, MD, who was not involved with the research, said: “This study is important because it is consistent with previous analyses that found a correlation between TIR and A1c.”

But, “I was surprised by the scatter plots which identified participants with TIR of 70% that also had A1c > 9%,” she added. “This highlights the importance of using multiple glycemic metrics to understand an individual’s risk for diabetes complications and to be aware of the limitations of the metrics.”

Dr. Thomas, from the University of Chicago, also noted that CGM is used in endocrinology clinics and increasingly in primary care clinics, “often to determine glycemic patterns to optimize therapeutic management but also to review TIR and, importantly, time below range to reduce the incidence of hypoglycemia.”

And people with type 2 diabetes are using CGM, Dr. Thomas noted, to understand their individual responses to medications, food choices, sleep quality and duration, exercise, and other day-to-day variables that affect glucose levels. “In my clinical practice, the information provided by personal CGM is empowering,” she said.

Effective April 4, 2023, Medicare “allows for the coverage of CGM in patients [with type 2 diabetes] treated with one injection of insulin daily and those not taking insulin but with a history of hypoglycemia,” Dr. Thomas noted, whereas “previously, patients needed to be prescribed at least three injections of insulin daily. Other insurers will hopefully soon follow.”

“I foresee CGM and TIR being widely used in clinical practice for people living with type 2 diabetes,” she said, “especially those who have ever had an A1c over 8%, those with a history of hypoglycemia, and those treated with medications that are known to cause hypoglycemia.”
 

How does TIR compare with A1c?

Dr. Goldenberg and colleagues set out to better understand how the emerging TIR metric compares with the traditional A1c value.

They performed a post-hoc analysis of data from the phase 4 SWITCH PRO study of basal insulin–treated patients with type 2 diabetes with at least one risk factor for hypoglycemia.

The patients were treated with insulin degludec or glargine 100 during a 16-week titration and 2-week maintenance phase, and then crossed over to the other treatment for the same time periods.

Glycemic control was evaluated using a blinded professional CGM (Abbott Freestyle Libro Pro). The primary outcome was TIR, which was defined as the percentage of time spent in the blood glucose range of 70-180 mg/dL.

There were 419 participants in the full analysis. Patients were a mean age of 63 and 48% were men. They had a mean body mass index of 32 kg/m² and had diabetes for a mean of 15 years.

There was a moderate inverse linear correlation between TIR and A1c at baseline, which became stronger following treatment intensification during the maintenance periods in the full cohort, and in a subgroup of patients with median A1c ≥ 7.5% (212 patients).

This correlation between TIR and A1c was poorer in the subgroup of patients with baseline median A1c < 7.5% (307 patients).

The data were widely scattered, “supporting the premise that A1c and TIR can be relatively crude surrogates of each other when it comes to individual patients,” Dr. Goldenberg and colleagues note.

Where individual patients have both low A1c and low TIR values, this might indicate frequent episodes of hypoglycemia.

A few individual patients had TIR > 70% but A1c approaching 9%. These patients may have different red blood cell physiology whereby A1c does not reflect average glycemic values, the researchers suggest.

The study was sponsored by Novo Nordisk and several authors are Novo Nordisk employees. The complete author disclosures are listed with the article. Dr. Thomas has reported no relevant financial relationships.

For patients with chronic, limb-threatening ischemia due to atherosclerosis that affects the arteries below the knee, a revascularization strategy using endovascular treatment as the first option was superior to one that prioritized vein bypass surgery in a new randomized trial.

In the Bypass Versus Angioplasty in Severe Ischaemia of the Leg (BASIL-2) trial, patients who received vein bypass as the first approach were more likely to require a major amputation or to die during follow-up than patients who were randomly assigned to the endovascular approach as first strategy.

“Our findings suggest that a best endovascular treatment first revascularization strategy is associated with a better amputation-free survival. This is mainly because the best endovascular treatment first revascularization strategy resulted in fewer deaths. Limb-related outcomes were similar between groups,” the authors stated.

“The BASIL-2 trial has produced a statistically robust and clinically meaningful result that is likely to have an influence on the management of chronic limb-threatening ischemia worldwide,” added the study’s chief investigator, Andrew Bradbury, MD, professor of vascular surgery at the University of Birmingham (England).

However, the results of the BASIL-2 trial conflict with those from two previous studies – BASIL-1 and BEST-CLI, which both suggested that a surgical approach for chronic limb-threatening ischemia may be most appropriate.

The BASIL-2 study was published online in The Lancet.

The authors explained that chronic limb-threatening ischemia, previously known as critical limb ischemia and severe ischemia of the leg, is the most severe form of peripheral arterial disease caused by atherosclerosis. Patients present with ischemic rest pain and tissue loss (ulceration, gangrene, or both) that usually affects the foot.

Mainly because of tobacco smoking and the growing prevalence of type 2 diabetes, chronic limb-threatening ischemia represents a growing burden on health care and social care services around the world.

Unless the blood supply to the affected limb is restored, patients with chronic limb-threatening ischemia are at high risk for amputation or death. Although it is universally agreed that – in addition to best medical therapy – virtually all patients with chronic limb-threatening ischemia should at least be considered for revascularization, there is continuing debate as to whether conducting vein bypass surgery, preferably using a vein taken from the patient’s own leg, or endovascular treatment (balloon angioplasty with or without stents) is preferable.

“BASIL-2 is the only randomized trial to specifically compare a vein bypass first with best endovascular treatment first revascularisation strategy in patients with chronic limb-threatening ischemia who required an infrapopliteal (with or without an additional more proximal infrainguinal) revascularization procedure to restore limb perfusion,” the authors noted.

For the trial, which was conducted at 41 vascular surgery units in the United Kingdom, Sweden, and Denmark, 345 patients with chronic limb-threatening ischemia who required an infrapopliteal revascularization procedure to restore limb perfusion were randomly assigned to receive either vein bypass or best endovascular treatment as their first revascularization procedure.

Most vein bypasses used the great saphenous vein and originated from the common or superficial femoral arteries. Most endovascular interventions comprised plain balloon angioplasty with selective use of plain or drug-eluting stents. Participants were followed up for a minimum of 2 years.

The primary outcome was amputation-free survival, defined as time to first major (above the ankle) amputation or death from any cause measured in the intention-to-treat population.

Results showed that major amputation or death occurred in 63% of patients in the vein bypass group and in 53% of those in the best endovascular treatment group (adjusted hazard ratio, 1.35; P = .037).

The results were driven by a higher death rate in the vein bypass group (53% vs. 45%; aHR, 1.37).

In both groups, the most common causes of morbidity and death, including death occurring within 30 days of first revascularization, were cardiovascular and respiratory events.

The authors noted that outcomes for the patients in the BASIL-2 trial were poor (median amputation-free survival was 3.8 years, and half the patients died within 5 years).

They pointed out that severe, multilevel atherosclerotic disease that causes chronic limb-threatening ischemia develops over many years, but at baseline in this study, around 20% of patients said they were still smoking, and around 70% of patients had diabetes, of whom around 50% required insulin. In addition, around 90% of the participants often had quite extensive tissue loss.

“These baseline data suggest that there might still be missed opportunities in public health and primary care to prevent chronic limb-threatening ischemia through medical therapy and lifestyle interventions and missed opportunities to refer patients to secondary care earlier once chronic limb-threatening ischemia begins to develop,” they suggested.

“Better prevention and timely referral are important: the BASIL-2 trial shows that, by the time patients present to vascular and endovascular surgeons and interventional radiologists with established chronic limb-threatening ischemia, their prognosis is often poor regardless of what form of revascularization they are offered,” they added.
 

Conflicting results

In an accompanying comment, Ankur Kalra, MD, Franciscan Health, Lafayette, Ind., and Ashish Kumar, MD, Cleveland Clinic Akron (Ohio) General, noted that atherosclerotic lower-extremity peripheral artery disease affects more than 230 million people worldwide, and prevalence is increasing. Chronic limb-threatening ischemia is a severe form of peripheral artery disease that affects 11% of patients with peripheral artery disease and is associated with significant cardiovascular morbidity and death.

Furthermore, amputation rates of 10%-40% during a 6-month follow-up of patients with chronic limb-threatening ischemia who were unable to undergo revascularization have been reported, highlighting the severity of atherosclerotic burden and the need for improved treatment strategies.

Dr. Kalra and Dr. Kumar pointed out that two previous randomized clinical trials compared surgical vein graft bypass with endovascular treatment for patients with chronic limb-threatening ischemia – the BASIL-1 trial, and the BEST-CLI trial.

In the BASIL-1 trial, vein bypass was associated with improved overall survival and amputation-free survival for patients who survived at least 2 years. The BEST-CLI trial also reported a lower risk of a composite of major adverse limb events or death among patients undergoing a surgery-first strategy, compared with endovascular therapy, mostly in patients with suitable single segment of great saphenous vein.

Dr. Kalra and Dr. Kumar said the findings of the BASIL-2 trial should be put in context with these previous studies, which report a positive or equivocal effect of surgery. The results of the BEST-CLI trial were driven by fewer major reinterventions and above-ankle amputations in the surgical group, whereas the results of the BASIL-2 trial were driven by fewer deaths in the best endovascular treatment group, “which potentially points towards a difference in the characteristics of the patients randomly assigned in the two trials.”

They concluded: “Considering the results of the BASIL-2 trial and the BEST-CLI trial, choice of intervention should be based on shared decision making between interventional cardiology, vascular surgery, and the patient, until more evidence is accrued.”

The BASIL-2 trial was funded by the U.K. National Institute of Health Research.

For patients with chronic, limb-threatening ischemia due to atherosclerosis that affects the arteries below the knee, a revascularization strategy using endovascular treatment as the first option was superior to one that prioritized vein bypass surgery in a new randomized trial.

In the Bypass Versus Angioplasty in Severe Ischaemia of the Leg (BASIL-2) trial, patients who received vein bypass as the first approach were more likely to require a major amputation or to die during follow-up than patients who were randomly assigned to the endovascular approach as first strategy.

“Our findings suggest that a best endovascular treatment first revascularization strategy is associated with a better amputation-free survival. This is mainly because the best endovascular treatment first revascularization strategy resulted in fewer deaths. Limb-related outcomes were similar between groups,” the authors stated.

“The BASIL-2 trial has produced a statistically robust and clinically meaningful result that is likely to have an influence on the management of chronic limb-threatening ischemia worldwide,” added the study’s chief investigator, Andrew Bradbury, MD, professor of vascular surgery at the University of Birmingham (England).
