Comparative analysis of three nutrition scores in predicting mortality after acute myocardial infarction

•Low nutrition score was associated with cardiovascular adverse outcomes in patients with acute myocardial infarction.•Nutrition scores had a negative correlation with high-sensitivity C-reaction protein and N-terminal probrain natriuretic peptide.•The geriatric nutritional risk index, the prognostic nutritional index, and the triglycerides, total cholesterol, and body weight index were linearly negatively associated with risk of all-cause death and major adverse cardiovascular events.•The geriatric nutritional risk index had the greatest incremental value in predicting associated risk among three nutrition scores.
