PARIS – The Geriatric Nutritional Risk Index proved to be an independent predictor of 5-year overall survival as well as the composite of major adverse cardiovascular and limb events in a prospective cohort study of 1,219 patients with peripheral artery disease, Yae Matsuo, MD, reported at the annual congress of the European Society of Cardiology.
The Geriatric Nutritional Risk Index (GNRI) is a score calculated with a formula based upon a patient’s height, serum albumin, and the ratio between ideal and actual body weight (Am J Clin Nutr. 2005 Oct;82(4):777-83). The GNRI tool has been shown to be an accurate prognosticator for clinical outcomes in patients on hemodialysis and those with heart failure. However, it’s predictive accuracy hasn’t been evaluated in patients with PAD, according to Dr. Matsuo, a cardiologist at Kitakanto Cardiovascular Hospital in Shibukawa, Japan.
“The Geriatric Nutritional Risk Index is simple to calculate – so easy – and I think it’s a better predictor than BMI,” she said.
Fifty-six percent of the PAD patients had a GNRI score greater than 98, indicative of no increased risk of malnutrition and nutritional deficiencies. Their 5-year overall survival rate was 81%, compared with 62% in patients with a score of 92-98, 40% in those with a score of 82-91, and 23% with a score of less than 82. Other independent predictors of overall survival in multivariate analysis were age, estimated glomerular filtration rate, ankle brachial index, and C-reactive protein level.
A GNRI score above 98 was also predictive of significantly lower 5-year risk of both major adverse cardiovascular events and the composite of major adverse cardiovascular and limb events than in patients with a score of 98 or less.
The key remaining unanswered question is whether providing timely nutritional support to PAD patients with a low GNRI score will result in improved overall and limb survival and other outcomes.
Dr. Matsuo reported having no financial conflicts.
