A descriptive study of patients with non ST elevated myocardial infarction (NSTEMI) at ibn e sina emergency hospital in 2025

Abstract

Ischemic Heart Disease (IHD) remains a major cardiovascular problem worldwide. Acute coronary syndrome includes ST-segment-elevation myocardial infarction and unstable angina/non-ST-segment-elevation myocardial infarction (NSTEMI), while stable angina represents another important form of ischemic heart disease. NSTEMI requires timely recognition because delayed diagnosis and treatment may result in adverse clinical outcomes. This descriptive case-series study was conducted in the Emergency Department of Ibn Sina Hospital from January to December 2025. A total of 3,027 patients were admitted to the General Internal Medicine Department, of whom 605 had ischemic heart disease, and 568 had acute coronary syndrome. Among these, 168 patients were diagnosed with NSTEMI and constituted the study population. NSTEMI accounted for 5.57% of all hospitalized patients and 27.7% of patients with ischemic heart disease. The mean age was 62.2 years, with a standard deviation of 21.2 years and a median age of 53 years. Most cases occurred among patients older than 51 years. Females constituted 55% and males 45% of cases. Common associated risk factors included sedentary lifestyle, dyslipidemia, obesity, and smoking. NSTEMI represents an important component of ischemic heart disease among hospitalized patients. Older age and major cardiovascular risk factors were prominent characteristics, emphasizing the importance of early diagnosis, risk-factor control, timely management, and appropriate follow-up.
