DOI : 10.31086/tjgeri.2021.203 Introduction: This study aimed to evaluate the predictive role of the Geriatric Nutrition Risk Index in long-term mortality of very elderly patients with ST-segment elevation myocardial infarction and to compare it with the other known objective nutritional indices, namely the Prognostic Nutritional Index and Controlling Nutritional Status.

Materials and Methods: A total of 212 eligible patients, aged 80 years or older, who were hospitalized with a diagnosis of ST-segment elevation myocardial infarction and underwent primary percutaneous coronary intervention were included in the study. Baseline patient characteristics, echocardiographic assessments, laboratory findings, and nutritional indices were assessed.

Results: During the median follow-up period of 34 months, 60 (28.3%) allcause mortalities were identified, and event-free cumulative rates were 46.3%, 81.4%, and 90.1% for Geriatric Nutrition Risk Index <100.5, 100.5?112.6, and >112.6, respectively (log-rank test, p < 0.0001). Receiver operating characteristic curve comparison analysis revealed that the Geriatric Nutrition Risk Index was a better predictor than the Controlling Nutritional Status, Prognostic Nutritional Index, Body Mass Index, and serum albumin (p < 0.001 for each pairwise comparison of Receiver operating characteristic curves).

Conclusion: It is important to evaluate malnutrition that is known to be associated with mortality in very elderly patients with ST-segment elevation myocardial infarction, who are more fragile than young people, and Geriatric Nutrition Risk Index -a simple and easy-to-calculate index- can be a guide in this regard.
