The prognostic impact of poor nutritional status and cardiac cachexia in myocardial infarction is not clearly understood. Recent studies have implied a prognostic value of the prognostic nutritional index (PNI) in colorectal surgeries and postoperative septic complications. The present study aimed to evaluate the prognostic value of PNI in ST-segment elevation myocardial infarction (STEMI) patients.We evaluated the in-hospital and long-term (3 years) prognostic impact of PNI on 1823 patients with STEMI undergoing primary percutaneous coronary intervention. Patients with lower PNI had significantly higher in-hospital and long-term mortality and major adverse cardiac events. After adjustment for all confounders, the in-hospital mortality rates were 7.9 times higher at the lower PNI level (95% CI: 5.0–15.8) than those at the higher PNI level. The long-term mortality rates were also 6.4 times higher at the lower PNI level (95% CI: 4.4–12.4) than those at the higher PNI level.The present study demonstrated that the PNI, calculated based on the serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients with STEMI.
