Cardiology

STOCKHOLM – Recent study results confirm that two agents from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class can significantly cut the incidence of adverse cardiovascular events in patients with heart failure with reduced ejection fraction (HFpEF), a disease especially common in people with type 2 diabetes, obesity, or both.

And findings from secondary analyses of the studies – including one reported at the annual meeting of the European Association for the Study of Diabetes – show that these SGLT2 inhibitors work as well for cutting incident adverse events (cardiovascular death or worsening heart failure) in patients with HFpEF and diabetes as they do for people with normal blood glucose levels.

But delivering treatment with these proven agents, dapagliflozin (Farxiga) and empagliflozin (Jardiance), first requires diagnosis of HFpEF, a task that clinicians have historically fallen short in accomplishing.

When in 2021, results from the EMPEROR-Preserved trial with empagliflozin and when in September 2022 results from the DELIVER trial with dapagliflozin established the efficacy of these two SGLT2 inhibitors as the first treatments proven to benefit patients with HFpEF, they also raised the stakes for clinicians to be much more diligent and systematic in evaluating people at high risk for developing HFpEF because of having type 2 diabetes or obesity, two of the most potent risk factors for this form of heart failure.
 

‘Vigilance ... needs to increase’

“Vigilance for HFpEF needs to increase because we can now help these patients,” declared Lars H. Lund, MD, PhD, speaking at the meeting. “Type 2 diabetes dramatically increases the incidence of HFpEF,” and the mechanisms by which it does this are “especially amenable to treatment with SGLT2 inhibitors,” said Dr. Lund, a cardiologist and heart failure specialist at the Karolinska Institute, Stockholm.

HFpEF has a history of going undetected in people with type 2 diabetes, an ironic situation given its high incidence as well as the elevated rate of adverse cardiovascular events when heart failure occurs in patients with type 2 diabetes compared with patients who do not have diabetes.

The key, say experts, is for clinicians to maintain a high index of suspicion for signs and symptoms of heart failure in people with type 2 diabetes and to regularly assess them, starting with just a few simple questions that probe for the presence of dyspnea, exertional fatigue, or both, an approach not widely employed up to now.

Clinicians who care for people with type 2 diabetes must become “alert to thinking about heart failure and alert to asking questions about signs and symptoms” that flag the presence of HFpEF, advised Naveed Sattar, MBChB, PhD, a professor of metabolic medicine at the University of Glasgow.

Soon, medical groups will issue guidelines for appropriate assessment for the presence of HFpEF in people with type 2 diabetes, Dr. Sattar predicted in an interview.
 

A need to probe

“You can’t simply ask patients with type 2 diabetes whether they have shortness of breath or exertional fatigue and stop there,” because often their first response will be no.

“Commonly, patients will initially say they have no dyspnea, but when you probe further, you find symptoms,” noted Mikhail N. Kosiborod, MD, codirector of Saint Luke’s Cardiometabolic Center of Excellence in Kansas City, Mo.

These people are often sedentary, so they frequently don’t experience shortness of breath at baseline, Dr. Kosiborod said in an interview. In some cases, they may limit their activity because of their exertional intolerance.

Once a person’s suggestive symptoms become known, the next step is to measure the serum level of N-terminal pro-B-type natriuretic peptide (NT-proBNP), a biomarker considered to be a generally reliable signal of existing heart failure when elevated.

Any value above 125 pg/mL is suggestive of prevalent heart failure and should lead to the next diagnostic step of echocardiography, Dr. Sattar said.

Elevated NT-proBNP has such good positive predictive value for identifying heart failure that it is tempting to use it broadly in people with type 2 diabetes. A 2022 consensus report from the American Diabetes Association says that “measurement of a natriuretic peptide [such as NT-proBNP] or high-sensitivity cardiac troponin is recommended on at least a yearly basis to identify the earliest HF [heart failure] stages and implement strategies to prevent transition to symptomatic HF.”
 

Test costs require targeting

But because of the relatively high current price for an NT-proBNP test, the cost-benefit ratio for widespread annual testing of all people with type 2 diabetes would be poor, some experts caution.

“Screening everyone may not be the right answer. Hundreds of millions of people worldwide” have type 2 diabetes. “You first need to target evaluation to people with symptoms,” advised Dr. Kosiborod.

He also warned that a low NT-proBNP level does not always rule out HFpEF, especially among people with type 2 diabetes who also have overweight or obesity, because NT-proBNP levels can be “artificially low” in people with obesity.

Other potential aids to diagnosis are assessment scores that researchers have developed, such as the H2FPEF score, which relies on variables that include age, obesity, and the presence of atrial fibrillation and hypertension.

However, this score also requires an echocardiography examination, another test that would have a questionable cost-benefit ratio if performed widely for patients with type 2 diabetes without targeting, Dr. Kosiborod said.
 

SGLT2 inhibitors benefit HFpEF regardless of glucose levels

A prespecified analysis of the DELIVER results that divided the study cohort on the basis of their glycemic status proved the efficacy of the SGLT2 inhibitor dapagliflozin for patients with HFpEF regardless of whether or not they had type 2 diabetes, prediabetes, or were normoglycemic at entry into the study, Silvio E. Inzucchi, MD, reported at the EASD meeting.

Treatment with dapagliflozin cut the incidence of the trial’s primary outcome of cardiovascular death or worsening heart failure by a significant 18% relative to placebo among all enrolled patients.

The new analysis reported by Dr. Inzucchi showed that treatment was associated with a 23% relative risk reduction among those with normoglycemia, a 13% reduction among those with prediabetes, and a 19% reduction among those with type 2 diabetes, with no signal of a significant difference among the three subgroups.

“There was no statistical interaction between categorical glycemic subgrouping and dapagliflozin’s treatment effect,” concluded Dr. Inzucchi, director of the Yale Medicine Diabetes Center, New Haven, Conn.

He also reported that, among the 6,259 people in the trial with HFpEF, 50% had diabetes, 31% had prediabetes, and a scant 19% had normoglycemia. The finding highlights once again the high prevalence of dysglycemia among people with HFpEF.

Previously, a prespecified secondary analysis of data from the EMPEROR-Preserved trial yielded similar findings for empagliflozin that showed the agent’s efficacy for people with HFpEF across the range of glucose levels.

The DELIVER trial was funded by AstraZeneca, the company that markets dapagliflozin (Farxiga). The EMPEROR-Preserved trial was sponsored by Boehringer Ingelheim and Eli Lilly, the companies that jointly market empagliflozin (Jardiance). Dr. Lund has been a consultant to AstraZeneca and Boehringer Ingelheim and to numerous other companies, and he is a stockholder in AnaCardio. Dr. Sattar has been a consultant to and has received research support from AstraZeneca and Boehringer Ingelheim, and he has been a consultant with numerous companies. Dr. Kosiborod has been a consultant to and has received research funding from AstraZeneca and Boehringer Ingelheim and has been a consultant to Eli Lilly and numerous other companies. Dr. Inzucchi has been a consultant to, given talks on behalf of, or served on trial committees for Abbott, AstraZeneca, Boehringer Ingelheim, Esperion, Lexicon, Merck, Novo Nordisk, Pfizer, and vTv Therapetics.

In 2002, two landmark trials found that targeted temperature management (TTM) after out-of-hospital cardiac arrest led to improvements in neurologic outcomes. The larger of the two trials found a reduction in mortality. Such treatment benefits are hard to come by in critical care in general and in out-of-hospital cardiac arrest in particular. With the therapeutic overconfidence typical of our profession, my institution embraced TTM quickly and completely soon after these trials were published. Remember, this was “back in the day” when sepsis management included drotrecogin alfa, Cortrosyn stim tests, tight glucose control (90-120 mg/dL), and horrible over-resuscitation via the early goal-directed therapy paradigm.

If you’ve been practicing critical care medicine for more than a few years, you already know where I’m going. Most of the interventions in the preceding paragraph were adopted but discarded before 2010. Though TTM has managed to stand the test of time, our confidence in its benefit has waned since 2002. Hypothermia – temperature management with a goal of 32-36° C – has been struggling to stay relevant ever since the publication of the TTM randomized controlled trial (RCT) in 2013. Then came the HYPERION trial, which brought the 32-36° C target back from the dead (pun definitely intended) in 2019. This is critical care medicine: Today’s life-saving intervention proves harmful tomorrow, but withholding it may constitute malpractice a few months down the road.

So where are we now? Good question. I’ve had seasoned neurointensivists insist that 33° C remains the standard of care and others who’ve endorsed normothermia. So much for finding an answer via my more specialized colleagues.

Let’s go to the guidelines then. Prompted largely by HYPERION, a temperature target of 32-36° C was endorsed in 2020 and 2021. Then came publication of the TTM2 trial, the largest temperature management RCT to date, which found no benefit to targeting 33° C. A network meta-analysis published in 2021 reached a similar conclusion. A recently released update by the same international guideline group now recommends targeting normothermia (< 37.7° C) and avoiding fever, and it specifically says that there is insufficient evidence to support a 32-36° C target. Okay, everyone tracking all that?

Lest I sound overly catty and nihilistic, I see all this in a positive light. Huge credit goes to the critical care medicine academic community for putting together so many RCTs. The scientific reality is that it takes “a lotta” sample size to clarify the effects of an intervention. Throw in the inevitable bevy of confounders (in- vs. out-of-hospital cardiac arrest, resuscitation time, initial rhythm, and so on), and you get a feel for the work required to understand a treatment’s true effects.

Advances in guideline science and the hard, often unpaid work of panels are also important. The guideline panel I’ve been citing came out for aggressive temperature control (32-36° C) a few months before the TTM2 RCT was published. In the past, they updated their recommendations every 5 years, but this time, they were out with a new manuscript that incorporated TTM2 in less than a year. If you’ve been involved at any level with producing guidelines, you can appreciate this achievement. Assuming that aggressive hypothermia is truly harmful, waiting 5 years to incorporate TTM2 could have led to significant morbidity.

I do take issue with you early adopters, though. Given the litany of failed therapies that have shown initial promise, and the well-documented human tendency to underestimate the impact of sample size, your rapid implementation of major interventions is puzzling. One might think you’d learned your lessons after seeing drotrecogin alfa, Cortrosyn stim tests, tight glucose control, early goal-directed therapy, and aggressive TTM come and go. Your recent enthusiasm for vitamin C after publication of a single before-after study suggests that you haven’t.

A network meta-analysis published in 2021 reached a similar conclusion. A recently released update by the same international guideline group now recommends targeting normothermia (< 37.7° C) and avoiding fever, and it specifically says that there is insufficient evidence to support a 32-36° C target. Okay, everyone tracking all that?

Lest I sound overly catty and nihilistic, I see all this in a positive light. Huge credit goes to the critical care medicine academic community for putting together so many RCTs. The scientific reality is that it takes “a lotta” sample size to clarify the effects of an intervention. Throw in the inevitable bevy of confounders (in- vs. out-of-hospital cardiac arrest, resuscitation time, initial rhythm, and so on), and you get a feel for the work required to understand a treatment’s true effects.

Advances in guideline science and the hard, often unpaid work of panels are also important. The guideline panel I’ve been citing came out for aggressive temperature control (32-36° C) a few months before the TTM2 RCT was published. In the past, they updated their recommendations every 5 years, but this time, they were out with a new manuscript that incorporated TTM2 in less than a year. If you’ve been involved at any level with producing guidelines, you can appreciate this achievement. Assuming that aggressive hypothermia is truly harmful, waiting 5 years to incorporate TTM2 could have led to significant morbidity.

I do take issue with you early adopters, though. Given the litany of failed therapies that have shown initial promise, and the well-documented human tendency to underestimate the impact of sample size, your rapid implementation of major interventions is puzzling. One might think you’d learned your lessons after seeing drotrecogin alfa, Cortrosyn stim tests, tight glucose control, early goal-directed therapy, and aggressive TTM come and go. Your recent enthusiasm for vitamin C after publication of a single before-after study suggests that you haven’t.

Aspirin may be of specific benefit for the primary prevention of cardiovascular disease in individuals with raised Lp(a) levels, a new study has suggested.

The study analyzed data from the ASPREE (ASPirin in Reducing Events in the Elderly) trial, which randomized 19,000 individuals aged 70 years or older without a history of cardiovascular disease to aspirin (100 mg/day) or placebo. While the main results, reported previously, showed no net benefit of aspirin in the overall population, the current analysis suggests there may be a benefit in individuals with raised Lp(a) levels.

Similar findings in the Women’s Health Study

Dr. Lacaze and colleagues point out that similar results have also been seen in another large aspirin primary prevention study – the Women’s Health Study (WHS).

The WHS compared aspirin 100 mg every other day with placebo in initially healthy younger women. Previously reported results showed that women carrying the rs3798220-C variant, associated with highly elevated Lp(a) levels, had a twofold higher risk of cardiovascular events than noncarrier women in the placebo group, but this risk was reduced in the aspirin group. And there was no increased risk of bleeding in women with elevated Lp(a).

“These results, in the absence of any other randomized controlled trial evidence or approved therapy for treating Lp(a)-associated risk, have been used by some physicians as justification for prescribing aspirin in patients with elevated Lp(a),” Dr. Lacaze and colleagues note.

“In the present study of the ASPREE trial population, our results were consistent with the WHS analysis, despite randomizing older individuals (both men and women),” they add.

They say this validation of the WHS result provides evidence that a very high-risk subgroup of individuals with highly elevated Lp(a) – those carrying the rs3798220-C allele – may benefit from low-dose aspirin for the primary prevention of cardiovascular events. Further, the benefits in this subgroup specifically may outweigh any bleeding risk.

But they point out that rs3798220-C carriers comprise only a small portion of all individuals with elevated Lp(a) in the general population, while the polygenic LPA-GRS explains about 60% of the variation in directly measured plasma Lp(a) levels and has the potential advantage of being able to identify a larger group of individuals at increased risk.

The researchers note, however, that it is not clear to what extent the LPA-GRS results add further evidence to suggest that individuals with elevated Lp(a), beyond rs3798220-C carriers, may be more likely to benefit from aspirin.

“If the benefit of aspirin extends beyond very high-risk rs3798220-C carriers alone, to the broader 20%-30% of individuals with elevated Lp(a), the potential utility of aspirin for the primary prevention of cardiovascular events would increase substantially,” they say.
 

‘Very high clinical relevance’

In an accompanying editorial, Ana Devesa, MD, Borja Ibanez, MD, PhD, and Valentin Fuster, MD, PhD, The National Center for Cardiovascular Research, Madrid, say that: “[Dr.] Lacaze et al. are to be congratulated for a study of very high clinical relevance that represents a first indication for primary prevention for patients at high cardiovascular risk.”

They explain that the pathogenic mechanism of Lp(a) is believed to be a combination of prothrombotic and proatherogenic effects, and the current findings support the hypothesis that the prothrombotic mechanism of Lp(a) is mediated by platelet aggregation. 

This would explain the occurrence of thrombotic events in the presence of atherosclerosis in that elevated Lp(a) levels may induce platelet adhesion and aggregation to the activated atherosclerotic plaque, thus enhancing the atherothrombotic process. Moreover, activated platelets release several mediators that result in cell adhesion and attraction of chemokines and proinflammatory cytokines, driving an inflammatory response and mediating atherosclerosis progression, they add.

The editorialists highlight the limitations of the study already acknowledged by the authors: The analysis used genotypes rather than elevated Lp(a) levels and included only those of European ancestry, meaning the results are difficult to extrapolate to other populations.

“The next steps in clinical practice should be defined, and there are still questions to be answered,” they conclude. “Will every patient benefit from antithrombotic therapies? Should all patients who have elevated Lp(a) levels be treated with aspirin?”

Drinking two to three daily cups of – ground, instant, or decaffeinated – is associated with significant reductions in new cardiovascular disease (CVD) and mortality risk, compared with avoiding coffee, a new analysis of the prospective UK Biobank suggests.

Ground and instant coffee, but not decaffeinated coffee, also was associated with reduced risk of new-onset arrhythmia, including atrial fibrillation.

“Our study is the first to look at differences in coffee subtypes to tease out important differences which may explain some of the mechanisms through which coffee works,” Peter M. Kistler, MD, of the Alfred Hospital and Baker Heart and Diabetes Institute, Melbourne, Australia, told this news organization.

“Daily coffee intake should not be discouraged by physicians but rather considered part of a healthy diet,” Dr. Kistler said.

“This study supports that coffee is safe and even potentially beneficial, which is consistent with most of the prior evidence,” Carl “Chip” Lavie, MD, who wasn’t involved in the study, told this news organization.

“We do not prescribe coffee to patients, but for the majority who like coffee, they can be encouraged it is fine to take a few cups daily,” said Dr. Lavie, with the Ochsner Heart and Vascular Institute in New Orleans.

The study was published online in the European Journal of Preventive Cardiology.

 

Clear cardiovascular benefits

A total of 449,563 UK Biobank participants (median age 58 years; 55% women), who were free of arrhythmias or other CVD at baseline, reported in questionnaires their level of daily coffee intake and preferred type of coffee.

During more than 12.5 years of follow-up, 27,809 participants (6.2%) died.

Drinking one to five cups per day of ground or instant coffee (but not decaffeinated coffee) was associated with a significant reduction in incident arrhythmia. The lowest risk was with four to five cups per day for ground coffee (hazard ratio [HR] 0.83; 95% confidence interval [CI], 0.76-0.91; P < .0001) and two to three cups per day for instant coffee (HR, 0.88; 95% CI, 0.85-0.92; P < .0001).

Habitual coffee drinking of up to five cups perday was also associated with significant reductions in the risk of incident CVD, when compared with nondrinkers.

Significant reductions in the risk of incident coronary heart disease (CHD) were associated with habitual coffee intake of up to five cups per day, with the lowest risk for CHD observed in those who consumed two to three cups per day (HR 0.89; 95% CI, 0.86-0.91; P < .0001).

Coffee consumption at all levels was linked to significant reduction in the risk of congestive cardiac failure (CCF) and ischemic stroke. The lowest risks were observed in those who consumed two to three cups per day, with HR, 0.83 (95% CI, 0.79-0.87; P < .0001) for CCF and HR, 0.84 (95% CI, 0.78-0.90; P < .0001) for ischemic stroke.

Death from any cause was significantly reduced for all coffee subtypes, with the greatest risk reduction seen with two to three cups per day for decaffeinated (HR, 0.86; 95% CI, 0.81-0.91; P < .0001); ground (HR, 0.73; 95% CI, 0.69-0.78; P < .0001); and instant coffee (HR, 0.89; 95% CI, 0.86-0.93; P < .0001).

“Coffee consumption is associated with cardiovascular benefits and should not empirically be discontinued in those with underlying heart rhythm disorders or cardiovascular disease,” Dr. Kistler told this news organization.

Plausible mechanisms

There are a number of proposed mechanisms to explain the benefits of coffee on CVD.

“Caffeine has antiarrhythmic properties through adenosine A1 and A2A receptor inhibition, hence the difference in effects of decaf vs. full-strength coffee on heart rhythm disorders,” Dr. Kistler explained.

Coffee has vasodilatory effects and coffee also contains antioxidant polyphenols, which reduce oxidative stress and modulate metabolism.

“The explanation for improved survival with habitual coffee consumption remains unclear,” Dr. Kistler said.

“Putative mechanisms include improved endothelial function, circulating antioxidants, improved insulin sensitivity, and reduced inflammation. Another potential mechanism includes the beneficial effects of coffee on metabolic syndrome,” he said.

“Caffeine has a role in weight loss through inhibition of gut fatty acid absorption and increase in basal metabolic rate. Furthermore, coffee has been associated with a significantly lower incidence of type 2 diabetes mellitus,” Dr. Kistler added.
 

Direction of relationship unclear

Charlotte Mills, PhD, University of Reading, England, said this study “adds to the body of evidence from observational trials associating moderate coffee consumption with cardioprotection, which looks promising.”

However, with the observational design, it’s unclear “which direction the relationship goes – for example, does coffee make you healthy or do inherently healthier people consume coffee? Randomized controlled trials are needed to fully understand the relationship between coffee and health before recommendations can be made,” Dr. Mills told the UK nonprofit Science Media Centre.

Annette Creedon, PhD, nutrition scientist with the British Nutrition Foundation, said it’s possible that respondents over- or underestimated the amount of coffee that they were consuming at the start of the study when they self-reported their intake.

“It is therefore difficult to determine whether the outcomes can be directly associated with the behaviors in coffee consumption reported at the start of the study,” she told the Science Media Centre.

The study had no funding. Dr. Kistler has received funding from Abbott Medical for consultancy and speaking engagements and fellowship support from Biosense Webster. Dr. Lavie has no relevant disclosures. Dr. Mills has worked in collaboration with Nestle on research relating to coffee and health funded by UKRI. Dr. Creedon has reported no relevant financial relationships.

Annette Creedon, PhD, nutrition scientist with the British Nutrition Foundation, said it’s possible that respondents over- or underestimated the amount of coffee that they were consuming at the start of the study when they self-reported their intake.

“It is therefore difficult to determine whether the outcomes can be directly associated with the behaviors in coffee consumption reported at the start of the study,” she told the Science Media Centre.

The study had no funding. Dr. Kistler has received funding from Abbott Medical for consultancy and speaking engagements and fellowship support from Biosense Webster. Dr. Lavie has no relevant disclosures. Dr. Mills has worked in collaboration with Nestle on research relating to coffee and health funded by UKRI. Dr. Creedon has reported no relevant financial relationships.

Apremilast may have an overall benefit for patients with cardiometabolic disease and psoriasis, new results from a nonrandomized clinical trial suggest.

The trial, led by Joel M. Gelfand, MD, MSCE, professor of dermatology and epidemiology and vice chair of clinical research in dermatology at the University of Pennsylvania, Philadelphia, found that apremilast (Otezla) has a neutral effect on aortic vascular inflammation in patients with moderate to severe psoriasis.

It also had variable, but generally favorable, associations with 68 cardiometabolic biomarkers tested and associations with reductions in both visceral and subcutaneous fat. Findings of the study were published online in JAMA Dermatology.

Fat reductions maintained at 1-year mark

The researchers found a 5%-6% reduction in subcutaneous and visceral fat at week 16 of the study that was maintained at the 1-year mark. “The fact that it was rock stable a year later is pretty encouraging,” Dr. Gelfand told this news organization.

As for effects on vascular inflammation, Dr. Gelfand said, “The good news is we didn’t find any adverse effects on aortic vascular inflammation, but we didn’t find any beneficial effects either. That was a little disappointing.

“The most surprising thing was really the effects on visceral adiposity,” he added. “I’m not aware of any other drug having demonstrated that effect.”

Michael S. Garshick, MD, a cardiologist with NYU Langone Health in New York, who was not involved with the trial, told this news organization that despite seemingly good epidemiologic evidence in observational studies that by treating psoriasis surrogates of cardiovascular risk can be reduced, this trial, like others before it, failed to reduce aortic vascular inflammation.

Seventy patients enrolled

In total, 70 patients with moderate to severe psoriasis were enrolled, 60 completed week 16, and 39 completed week 52 of the single-arm, open-label trial conducted between April 2017 and August 2021 at seven dermatology sites in the United States.

Participants took 30 mg of apremilast, an oral phosphodiesterase-4 (PDE-4) inhibitor approved for treating psoriasis and psoriatic arthritis, twice daily. Participants’ average age was 47.5 years; most were male (77.1%) and White (82.9%); almost 6% were Black. Average body mass index was 30 kg/m². Patients could not have received biologics within 90 days of study baseline (or 180 days for ustekinumab [Stelara]).

There was no change in aortic vascular inflammation at week 16 (target to background ratio, −0.02; 95% confidence interval [CI], −0.08 to 0.05; P = .61) or week 52 (target to background ratio, −0.07; 95% CI, −0.15 to 0.01; P = .09) compared with baseline.

“At week 16, there were reductions in levels of interleukin-1b, fetuin A, valine, leucine, and isoleucine,” the authors wrote, adding that at week 52, compared with baseline, “there were reductions in levels of ferritin, cholesterol efflux capacity, beta-hydroxybutyrate, acetone, and ketone bodies, and an increase in levels of apolipoprotein A-1.”

This study highlights the importance of screening, Dr. Garshick said.

He and Dr. Gelfand said people with psoriatic disease tend to be vastly underscreened for cardiovascular risk factors.

Dr. Gelfand said, “If we did what we knew worked – meaning we screened them for diabetes, we screen their cholesterol, we check their blood pressure, and we adequately treated those traditional cardiovascular risk factors, we probably could narrow the gap quite a bit” in terms of the lower life expectancy people face when they have more significant psoriasis.

Celgene was the initial funding sponsor; sponsorship was then transferred to Amgen. The authors designed, executed, analyzed, and reported the study. Celgene provided nonbinding input into study design, and Amgen provided nonbinding input into the reporting of results. Dr. Gelfand reported numerous disclosures with various pharmaceutical companies and organizations. Dr. Garshick reported no relevant financial relationships.

STOCKHOLM – Weight loss should be a co–primary management goal for type 2 diabetes in adults, according to a new comprehensive joint consensus report from the European Association for the Study of Diabetes and the American Diabetes Association.

And while metformin is still recommended as first-line therapy for patients with type 2 diabetes with no other comorbidities, the statement expands the indications for use of other agents or combinations of agents as initial therapy for subgroups of patients, as part of individualized and patient-centered decision-making.

Last updated in 2019, the new “Management of Hyperglycemia in Type 2 Diabetes” statement also places increased emphasis on social determinants of health, incorporates recent clinical trial data for cardiovascular and kidney outcomes for sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagonlike peptide–1 (GLP-1) agonists to broaden recommendations for cardiorenal protection, and discusses health behaviors such as sleep and sitting. It also targets a wider audience than in the past by addressing health system organization to optimize delivery of diabetes care.

The new statement was presented during a 90-minute session at the annual meeting of the EASD, with 12 of its 14 European and American authors as presenters. The document was simultaneously published in Diabetologia and Diabetes Care.

During the discussion, panel member Jennifer Brigitte Green, MD, commented: “Many of these recommendations are not new. They’re modest revisions of recommendations that have been in place for years, but we know that actual implementation rates of use of these drugs in patients with established comorbidities are very low.”

“I think it’s time for communities, health care systems, etc, to actually introduce these as expectations of care... to assess quality because unless it’s considered formally to be a requirement of care I just don’t think we’re going to move that needle very much,” added Dr. Green, who is professor of medicine at Duke University, Durham, N.C.

Vanita R. Aroda, MD, of the division of endocrinology, diabetes, and hypertension at Brigham and Women’s Hospital, Boston, commented: “In the past, sometimes these recommendations created fodder for debate, but I don’t think this one will. It’s just really solidly evidence based, with the rationales presented throughout, including the figures. I think just having very clear evidence-based directions should support their dissemination and use.”
 

Weight management plays a prominent role in treatment

In an interview, writing panel cochair John B. Buse, MD, PhD, said: “We are saying that the four major components of type 2 diabetes care are glycemic management, cardiovascular risk management, weight management, and prevention of end-organ damage, particularly with regard to cardiorenal risk.”

“The weight management piece is much more explicit now,” said Dr. Buse, director of the Diabetes Center at the University of North Carolina at Chapel Hill.

He noted that recent evidence from the intensive lifestyle trial DiRECT, conducted in the United Kingdom, the bariatric surgery literature, and the emergence of potent weight-loss drugs have meant that “achieving 10%-15% body weight loss is now possible.

“So, aiming for remission is something that might be attractive to patients and providers. This could be based on weight management, with the [chosen] method based on shared decision-making.”

According to the new report: “Weight loss of 5%-10% confers metabolic improvement; weight loss of 10%-15% or more can have a disease-modifying effect and lead to remission of diabetes, defined as normal blood glucose levels for 3 months or more in the absence of pharmacological therapy in a 2021 consensus report.”

“Weight loss may exert benefits that extend beyond glycemic management to improve risk factors for cardiometabolic disease and quality of life,” it adds.
 

Individualization featured throughout

The report’s sections cover principles of care, including the importance of diabetes self-management education and support and avoidance of therapeutic inertia. Detailed guidance addresses therapeutic options including lifestyle, weight management, and pharmacotherapy for treating type 2 diabetes.

Another entire section is devoted to personalizing treatment approaches based on individual characteristics, including new evidence from cardiorenal outcomes studies for SGLT2 inhibitors and GLP-1 agonists that have come out since the last consensus report.

The document advises: “Consider initial combination therapy with glucose-lowering agents, especially in those with high [hemoglobin] A1c at diagnosis (that is, > 70 mmol/mol [> 8.5%]), in younger people with type 2 diabetes (regardless of A1c), and in those in whom a stepwise approach would delay access to agents that provide cardiorenal protection beyond their glucose-lowering effects.”
 

Designed to be used and user-friendly

Under the “Putting it all together: strategies for implementation” section, several lists of “practical tips for clinicians” are provided for many of the topics covered.

A series of colorful infographics are included as well, addressing the “decision cycle for person-centered glycemic management in type 2 diabetes,” including a chart summarizing characteristics of available glucose-lowering medications, including cardiorenal protection.

Also mentioned is the importance of 24-hour physical behaviors (including sleep, sitting, and sweating) and the impact on cardiometabolic health, use of a “holistic person-centered approach” to type 2 diabetes management, and an algorithm on insulin use.

Dr. Buse has financial ties to numerous drug and device companies. Dr. Green is a consultant for AstraZeneca, Pfizer, Boehringer Ingelheim/Lilly, Bayer, Sanofi, Anji, Vertex/ICON, and Valo. Dr. Aroda has served as a consultant for Applied Therapeutics, Duke, Fractyl, Novo Nordisk, Pfizer, and Sanofi.

A look at the top cardiovascular disease (CVD) diagnoses in U.S. emergency departments (EDs) suggests that many heart-related emergencies are due to poorly controlled high blood pressure.

In a study of more than 20 million ED visits, about one-third of CVD-related ED visits in the United States were for hypertension-related conditions.

Overall, 13% of ED visits, representing more than 2.7 million individuals, were for essential hypertension.

Nationwide sample

The researchers studied more than 20.6 million ED encounters in adults with a primary CVD diagnosis using data from the Nationwide Emergency Department Sample between 2016 and 2018.

In the sample, 49% were women, and the median age was 67 years. Men had poorer overall baseline cardiometabolic profiles, but women had higher rates of obesity, hypertension, and cerebrovascular disease. The majority had Medicare or Medicaid insurance.

In women, essential hypertension was the most common reason for an ED visit (16%), followed by hypertensive heart or kidney disease (14%) and atrial fibrillation (AF)/flutter (10%).

In men, the top three reasons were hypertensive heart or kidney disease (15%), essential hypertension (11%), and acute myocardial infarction (AMI, 11%).

On presentation, women were significantly more likely to have essential hypertension, hypertensive crisis, AF/flutter, supraventricular tachycardia, pulmonary embolism, or ischemic stroke, while men were more likely to have AMI, or cardiac arrest.

“Previous studies have shown sex differences in patterns of CVD among hospitalized patients,” Dr. Mamas noted. “However, examining CVD encounters in the ED provides a more complete picture of the cardiovascular healthcare needs of men and women, as it captures encounters prior to hospitalization.”

He noted that previous studies of CVD emergency visits are limited to suspected MI visits. “Therefore, this analysis of 15 CVD conditions helps to better understand the full spectrum of acute CVD needs, including sex disparities in hospitalization and risk of death,” Dr. Mamas said.
 

Sex differences in outcomes

The study found that outcomes from the emergency CVD visits were slightly different for men and women.

Overall, women were less likely than were men to die (3.3% vs. 4.3%) or be hospitalized (49.1% vs. 52.3%) after an ED visit for CVD. The difference may be due to women’s generally lower-risk diagnoses, Dr. Mamas said, but there could be an underestimation of deaths in women.

In logistic regression models adjusted for baseline covariates, women with intracranial hemorrhage (ICH) had a higher risk of being admitted to hospital or dying compared with men with ICH.

Men were more likely to die if they presented with hypertensive heart or kidney disease, AF/flutter, AMI or cardiac arrest, the researchers found. 

“We did not track deaths outside of the hospital setting,” Dr. Mamas pointed out. Given past evidence that women are more likely to be inappropriately discharged from the ED, and strong evidence for the systemic undertreatment of women, further study is warranted to track outcomes beyond the ED visit,” he added.

The researchers called for further research into understanding the underlying factors driving the differences in CVD patterns and outcomes between men and women.

Reached for comment, Maryann McLaughlin, MD, a cardiologist at Mount Sinai Hospital, New York, said: “Hypertension is a silent killer” and this study “reiterates that people need to get their blood pressure checked more regularly.

“In the very least, if they do present to the hospital as not feeling well or whatever it is, and they are identified as having high blood pressure, that’s an important opportunity to really teach them about hypertension and have them follow-up with it,” Dr. McLaughlin told this news organization. 

The study was supported by Health Data Research UK. Dr. Keele and Dr. McLaughlin have reported no relevant financial relationships.

The researchers studied more than 20.6 million ED encounters in adults with a primary CVD diagnosis using data from the Nationwide Emergency Department Sample between 2016 and 2018.

In the sample, 49% were women, and the median age was 67 years. Men had poorer overall baseline cardiometabolic profiles, but women had higher rates of obesity, hypertension, and cerebrovascular disease. The majority had Medicare or Medicaid insurance.

In women, essential hypertension was the most common reason for an ED visit (16%), followed by hypertensive heart or kidney disease (14%) and atrial fibrillation (AF)/flutter (10%).

In men, the top three reasons were hypertensive heart or kidney disease (15%), essential hypertension (11%), and acute myocardial infarction (AMI, 11%).

On presentation, women were significantly more likely to have essential hypertension, hypertensive crisis, AF/flutter, supraventricular tachycardia, pulmonary embolism, or ischemic stroke, while men were more likely to have AMI, or cardiac arrest.

“Previous studies have shown sex differences in patterns of CVD among hospitalized patients,” Dr. Mamas noted. “However, examining CVD encounters in the ED provides a more complete picture of the cardiovascular healthcare needs of men and women, as it captures encounters prior to hospitalization.”

He noted that previous studies of CVD emergency visits are limited to suspected MI visits. “Therefore, this analysis of 15 CVD conditions helps to better understand the full spectrum of acute CVD needs, including sex disparities in hospitalization and risk of death,” Dr. Mamas said.
 

Sex differences in outcomes

The study found that outcomes from the emergency CVD visits were slightly different for men and women.

Overall, women were less likely than were men to die (3.3% vs. 4.3%) or be hospitalized (49.1% vs. 52.3%) after an ED visit for CVD. The difference may be due to women’s generally lower-risk diagnoses, Dr. Mamas said, but there could be an underestimation of deaths in women.

In logistic regression models adjusted for baseline covariates, women with intracranial hemorrhage (ICH) had a higher risk of being admitted to hospital or dying compared with men with ICH.

Men were more likely to die if they presented with hypertensive heart or kidney disease, AF/flutter, AMI or cardiac arrest, the researchers found. 

“We did not track deaths outside of the hospital setting,” Dr. Mamas pointed out. Given past evidence that women are more likely to be inappropriately discharged from the ED, and strong evidence for the systemic undertreatment of women, further study is warranted to track outcomes beyond the ED visit,” he added.

The researchers called for further research into understanding the underlying factors driving the differences in CVD patterns and outcomes between men and women.

Reached for comment, Maryann McLaughlin, MD, a cardiologist at Mount Sinai Hospital, New York, said: “Hypertension is a silent killer” and this study “reiterates that people need to get their blood pressure checked more regularly.

“In the very least, if they do present to the hospital as not feeling well or whatever it is, and they are identified as having high blood pressure, that’s an important opportunity to really teach them about hypertension and have them follow-up with it,” Dr. McLaughlin told this news organization. 

The study was supported by Health Data Research UK. Dr. Keele and Dr. McLaughlin have reported no relevant financial relationships.

A look at the top cardiovascular disease (CVD) diagnoses in U.S. emergency departments (EDs) suggests that many heart-related emergencies are due to poorly controlled high blood pressure.

In a study of more than 20 million ED visits, about one-third of CVD-related ED visits in the United States were for hypertension-related conditions.

Overall, 13% of ED visits, representing more than 2.7 million individuals, were for essential hypertension.

BOSTON – There’s an intriguing plot twist in the story of SYMPLICITY HTN-3, the sham-controlled clinical trial that nearly put the kibosh on renal denervation (RDN) therapy as a promising approach to treatment-resistant hypertension (HTN).

The trial famously showed no benefit for systolic blood pressure (BP) from the invasive procedure at 6 months and 12 months, dampening enthusiasm for RDN in HTN for both physicians and industry. But it turns out that disappointment in the study may have been premature.

The procedure led to significant improvements in systolic BP, whether in-office or ambulatory, compared with a sham control procedure, in a new analysis that followed the trial’s patients out to 3 years. Those who underwent RDN also required less intense antihypertensive drug therapy.

“These findings support that durable blood pressure reductions with radiofrequency renal artery denervation, in the presence of lifestyle modification and maximal medical therapy, are safely achievable,” Deepak L. Bhatt, MD, said in a Sept. 18 presentation at the Transcatheter Cardiovascular Therapeutics annual meeting, which was sponsored by the Cardiovascular Research Foundation.

Dr. Bhatt, of Boston’s Brigham and Women’s Hospital and Harvard Medical School, is lead author on the report published in The Lancet simultaneously with his presentation.

Strides in RDN technology and trial design since the neutral primary SYMPLICITY HTN-3 results were reported in 2014 have long since restored faith in the procedure, which is currently in advanced stages of clinical trials and expected to eventually make a mark on practice.

But Roxana Mehran, MD, not connected to SYMPLICITY HTN-3, expressed caution in interpreting the current analysis based on secondary endpoints and extended follow-up time.

And elsewhere at the TCT sessions, observers of the trial as well as Dr. Bhatt urged similar cautions interpreting “positive” secondary results from trials that were “negative” in their primary analyses.

Still, “I believe there is no question that we have now enough evidence to say that renal denervation on top of medications is probably something that we’re going to be seeing in the future,” Dr. Mehran, of the Icahn School of Medicine at Mount Sinai, New York, told this news organization.

Importantly, and a bit controversially, the RDN group in the 36-month SYMPLICITY HTN-3 analysis includes patients originally assigned to the sham control group who crossed over to receive RDN after the trial was unblinded. Their “control” BP responses were thereafter imputed by accepted statistical methodology that Dr. Bhatt characterized as “last observation carried forward.”

That’s another reason to be circumspect about the current results, observed Naomi Fisher, MD, also of Brigham and Women’s and Harvard Medical School, as a panelist following Dr. Bhatt’s formal presentation.

“With all the missing data and imputational calculations,” she said, “I think we have to apply caution in the interpretation.”

She also pointed out that blinding in the trial was lifted at 6 months, allowing patients to learn their treatment assignment, and potentially influencing subsequent changes to medications.  

They were prescribed, on average, about five antihypertensive meds, Dr. Fisher noted, and “that’s already a red flag. Patients taking that many medications generally aren’t universally taking them. There’s very high likelihood that there could have been variable adherence.”

Patients who learned they were in the sham control group, for example, could have “fallen off” taking their medications, potentially worsening outcomes and amplifying the apparent benefit of RDN. Such an effect, Dr. Fisher said, “could have contributed” to the study’s long-term results.

As previously reported, the single-blind SYMPLICITY HTN-3 had randomly assigned 535 patients to either RDN or a sham control procedure, 364 and 171 patients respectively, at 88 U.S. centers. The trial used the Symplicity Flex RDN radiofrequency ablation catheter (Medtronic).

For study entry, patients were required to have office systolic BP of at least 160 mm Hg and 24-hour ambulatory systolic BP of at least 135 mm Hg despite stable, maximally tolerated dosages of a diuretic plus at least two other antihypertensive agents.

Blinding was lifted at 6 months, per protocol, after which patients in the sham control group who still met the trial’s BP entry criteria were allowed to cross over and undergo RDN. The 101 controls who crossed over were combined with the original active-therapy cohort for the current analysis.

From baseline to 36 months, mean number of medication classes per patient maintained between 4.5 and 5, with no significant difference between groups at any point.

However, medication burden expressed as number of doses daily held steady between 9.7 to 10.2 for controls while the RDN group showed a steady decline from 10.2 to 8.4. Differences between RDN patients and controls were significant at both 24 months (P = .01) and 36 months (P = .005), Dr. Bhatt reported.

Among people with HIV (PWH), coinfection with hepatitis C (HCV) is associated with an 85% increase in risk of myocardial infarction (MI) every decade, a new analysis suggests.

By contrast, the risk increases by 30% every 10 years among PWH without HCV infection.

“There is other evidence that suggests people with HIV and HCV have a greater burden of negative health outcomes,” senior author Keri N. Althoff, PhD, MPH, of the Johns Hopkins Bloomberg School of Public Health in Baltimore, said in an interview. “But the magnitude of ‘greater’ was bigger than I expected.”

“Understanding the difference HCV can make in the risk of MI with increasing age among those with – compared to without – HCV is an important step for understanding additional potential benefits of HCV treatment (among PWH),” she said.

The amplified risk with age occurred even though, overall, the association between HCV coinfection and increased risk of type 1 myocardial infarction (T1MI) was not significant, the analysis showed.

The study was published online in the Journal of the American Heart Association.

How age counts

Dr. Althoff and colleagues analyzed data from 23,361 PWH aged 40-79 who had initiated antiretroviral therapy between 2000 and 2017. The primary outcome was T1MI.

A total of 4,677 participants (20%) had HCV. Eighty-nine T1MIs occurred among PWH with HCV (1.9%) vs. 314 among PWH without HCV (1.7%). In adjusted analyses, HCV was not associated with increased T1MI risk (adjusted hazard ratio, 0.98).

However, the risk of T1MI increased with age and was augmented in those with HCV (aHR per 10-year increase in age, 1.85) vs. those without HCV (aHR, 1.30).

Specifically, compared with those without HCV, the estimated T1MI risk was 17% higher among 50- to 59-year-olds with HCV and 77% higher among those 60 and older; neither association was statistically significant, although the authors suggest this probably was because of the smaller number of participants in the older age categories.

Even without HCV, the risk of T1MI increased in participants who had traditional risk factors. The risk was significantly higher among PWH aged 40-49 with diabetes, hypertension, chronic kidney disease, protease inhibitor (PI) use, and smoking, whereas among PWH aged 50-59, the T1MI risk was significantly greater among those with hypertension, PI use, and smoking.

Among those aged 60 or older, hypertension and low CD4 counts were associated with a significantly increased T1MI risk.

“Clinicians providing health care to people with HIV should know their patients’ HCV status,” Dr. Althoff said, “and provide support regarding HCV treatment and ways to reduce their cardiovascular risk, including smoking cessation, reaching and maintaining a healthy BMI, and substance use treatment.”
 

Truly additive?

American Heart Association expert volunteer Nieca Goldberg, MD, a clinical associate professor of medicine at New York University and medical director of Atria NY, said the increased T1MI risk with coinfection “makes sense” because both HIV and HCV are linked to inflammation.

However, she said in an interview, “the fact that the authors didn’t control for other, more traditional heart attack risk factors is a limitation. I would like to see a study that takes other risk factors into consideration to see if HCV is truly additive.”

Meanwhile, like Dr. Althoff, she said, “Clinicians should be taking a careful history that includes chronic infections as well as traditional heart risk factors.”

Additional studies are needed, Dr. Althoff agreed. “There are two paths we are keenly interested in pursuing. The first is understanding how metabolic risk factors for MI change after HCV treatment. We are working on this.”

“Ultimately,” she said, “we want to compare MI risk in people with HIV who had successful HCV treatment to those who have not had successful HCV treatment.”

In their current study, they had nearly 2 decades of follow-up, she noted. “Although we don’t need to wait that long, we would like to have close to a decade of potential follow-up time (since 2016, when sofosbuvir/velpatasvir became available) so that we have a large enough sample size to observe a sufficient number of MIs within the first 5 years after successful HCV treatment.”

“Ultimately,” she said, “we want to compare MI risk in people with HIV who had successful HCV treatment to those who have not had successful HCV treatment.”

In their current study, they had nearly 2 decades of follow-up, she noted. “Although we don’t need to wait that long, we would like to have close to a decade of potential follow-up time (since 2016, when sofosbuvir/velpatasvir became available) so that we have a large enough sample size to observe a sufficient number of MIs within the first 5 years after successful HCV treatment.”

No commercial funding or relevant disclosures were reported.

STOCKHOLM – Among animal protein foods, low-fat dairy consumption may minimize the risk of developing type 2 diabetes while red meat raises that risk, a new analysis finds.

“A plant-based dietary pattern with limited intake of meat, moderate intake of fish, eggs, and full-fat dairy, and habitual consumption of yogurt, milk, or low-fat dairy, might represent the most feasible, sustainable, and successful population strategy to optimize the prevention of type 2 diabetes,” lead author Annalisa Giosuè, MD, of the University of Naples (Italy) Federico II, told this news organization.

She presented the findings from an umbrella review of 13 dose-response meta-analyses of prospective cohort studies at the annual meeting of the European Association for the Study of Diabetes.

The study is believed to be the first comprehensive overview of the available evidence from all published meta-analyses on the relationship between well-defined amounts of animal-origin foods and the risk of type 2 diabetes.

Dr. Giosuè and colleagues focused on animal-based foods because they represent a gap in most guidelines for type 2 diabetes prevention, she explained.

“The existing evidence and dietary recommendations for type 2 diabetes prevention are mainly based on the appropriate consumption of plant foods: high amounts of the fiber-rich ones and low consumption of the refined ones as well as those rich in free sugars. And also on the adequate choice among fat sources – reduction of saturated fat sources like butter and cream and replacement with plant-based poly- and monounsaturated fat sources like nontropical vegetable oils. But not on the most suitable choices among different animal foods for the prevention of type 2 diabetes,” she explained.

The new findings are in line with the Mediterranean diet in that, while plant based, it also limits red-meat consumption, but not all animal-based foods, and has consistently been associated with a reduced risk of type 2 diabetes. Vegetarian diets have also been associated with a reduced risk of type 2 diabetes, but far less evidence is available for that, she said.

Asked for comment, session moderator Matthias Schulze, MD, head of the department of molecular epidemiology at the German Institute of Human Nutrition, Berlin, said: “Decreasing intake of red and processed meat is already a strong recommendation, and these data support that. You have to make choices for and against [certain] foods. So, if you decide to eat less red meat, then the question is what do you eat instead? This study shows that specifically other animal products, like dairy and ... fish or white meat sources ... are healthy among the animal-based foods. But you could also obviously look at plant-based foods as protein sources as well.”

And Dr. Schulze noted that the data suggest another dimension to type 2 diabetes prevention beyond simply focusing on weight loss.

“You can achieve weight loss with very different diets. Diet quality plays an important role. These data support that if you look at diabetes prevention, then you would focus on people with high intakes of specific animal-based foods, besides looking at overweight and obesity. Then you could intervene to reduce this intake, with potential substitutions with other animal foods like fish or white meat, or plant-based sources of proteins.”
 

Red meat damages, dairy protects

The 13 meta-analyses included 175 summary risk ratios for type 2 diabetes incidence for the consumption of total meat, red meat, white meat, processed meats, fish, total dairy, full-fat dairy, low-fat dairy, milk, cheese, yogurt, or eggs.

Significant increases in the risk of developing type 2 diabetes were found for consumption of 100 g/day of total meat (SRR, 1.20; 20% increase) and red meat (SRR, 1.22, 22% increase) and with 50 g/day of processed meats (SRR, 1.30; 30% increase). A borderline increased risk was also seen for 50 g/day of white meat (SRR, 1.04; 4% increase).

The opposite was found for dairy foods. Inverse associations for type 2 diabetes development were found for an intake of 200 g/day of total dairy (SRR, 0.95; 5% reduction), low-fat dairy (SRR, 0.96; 4% reduction), milk (SRR, 0.90; 10% reduction), and for 100 g/day of yogurt (SRR, 0.94, 6% reduction).

Neutral (nonsignificant) effects were found for 200 g/day of full-fat dairy (SRR, 0.98) and for 30 g/day of cheese (SRR, 0.97). Fish consumption also had a neutral association with type 2 diabetes risk (SRR, 1.04 for 100 g/day) as did one egg per day (SRR, 1.07), but evidence quality was low.

And, Dr. Giosuè noted during her presentation, these relationships could change with alterations in the amounts consumed.

Dr. Schulze commented: “Fish is more clearly related to reduced cardiovascular risk than for preventing type 2 diabetes, where we’ve had mixed results. They might not always be the same.”
 

What are the mechanisms?

The reasons for these positive and negative associations aren’t entirely clear, but Dr. Giosuè noted that dairy products contain several nutrients, vitamins, and other components, such as calcium and vitamin D, that have potential beneficial effects on glucose metabolism.

In particular, she said, “Whey proteins in milk have a well-known beneficial effect on the regulation of the rise of glucose levels in the blood after meals, and also on the control of appetite and body weight.”

Moreover, probiotics found in yogurt have been linked to protective effects against weight gain and obesity, which “may in part [explain] the beneficial role of yogurt in type 2 diabetes prevention.”

Meat, in contrast, is full of cholesterol, saturated fatty acids, and heme iron, which can promote subclinical inflammation and oxidative stress, which may in turn, affect insulin sensitivity, Dr. Giosuè explained. What’s more, “processed meats also contain nitrates, nitrites, and sodium that can contribute to pancreatic cell damage and vascular dysfunction, thus affecting insulin sensitivity.”

And white meat (poultry) has a lower fat content than red meats such as beef, lamb, and pork, as well as a more favorable fatty acid profile and a lower heme-iron content, she said in an interview.

What about vegan diets? The devil is in the details

Asked about the relative health benefits of diets that completely eliminate animal-based foods, Dr. Giosuè replied: “What is important to keep in mind when hearing about the potential of vegan diets to prevent, or manage, or induce the remission of type 2 diabetes, is that the inclusion in the diet of solely foods of plant origin does not mean ‘automatically’ to eat only foods that are good for diabetes prevention.”

“Just like the exclusion of all foods of animal origin is not equivalent to reduce the risk of type 2 diabetes ... Solid evidence has demonstrated that plant foods which are refined and/or rich in free sugars like white bread, biscuits, and sweetened beverages are as harmful as red and processed meats for diabetes incidence and progression.”

Dr. Giosuè and Dr. Schulze have reported no relevant financial relationships.
