The Role of Prognostic Nutritional Index in Predicting Multivessel Disease in Patients with ST-Segment Elevation Myocardial Infarction

Acute coronary syndromes (ACS) are common diseases and one of the most common causes of death in the world. The most feared ACS is ST segment elevation myocardial infarction (STEMI). Approximately 50% of STEMI patients have lesions in multivessel disease (MVD), and this is associated with poor outcomes. In this study, we aimed to evaluate prognostic nutritional index (PNI) in patients with STEMI and MVD. 1708 patients diagnosed with STEMI were included in the study. The patients' blood parameters, electrocardiography and echocardiography findings, coronary angiography images were recorded and calculations were made. The mean follow-up period was 38.8±10.3 months. The mean age of 1708 patients was 56.7±12.3 years, and 1370 (80.2) of the patients were male. Lower PNI was associated with MVD (+). Mortality was observed more in the MVD (+) group (p
