Risk Factors for In-Hospital Mortality in ST-Elevation Myocardial Infarction

Objective: In this study, we aimed to evaluate the in-hospital mortality indicators in patients presenting with ST-elevation myocar- dial infarction (STEMI) to our clinic and undergoing primary angioplasty. Methods: Four hundred patients presenting to our clinic with a diagnosis of STEMI and undergoing primary angioplasty were included in the study. Patient files were retrospectively reviewed. The relationship between in-hospital mortality and the development of complications after primary angioplasty and patients’ demographic, clinical, and laboratory characteristics were evaluated. Results: In the patient group included in the study, advanced age (≥65), diabetes mellitus, hypertension, and female gender were found to increase in-hospital mortality significantly. A significant increase in in-hospital mortality was observed in patients with left ventricular ejection fraction (LV EF) below 40%. Elevated baseline creatinine and troponin levels, high heart rate, presence of shock, and hypotension significantly increased in-hospital mortality in patients. Conclusion: In our study, we found that the risk factors, clinical and laboratory characteristics, and complications developed in patients presenting with acute STEMI are directly related to patient mortality. Identifying these mortality predictors is essential in determining patient risk, guiding treatment, and follow-up.
