Short-Term Clinical Outcomes in ST-Elevation versus Non-ST-Elevation Myocardial Infarction: A 100-Case Hospital-Based Study

ABSTRACTBackground: ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) differ in their pathophysiology and management; however, data on short-term outcomes in hospitalized patients in Bangladesh remain limited. Objectives: This study compared the clinical characteristics, management strategies, and short-term outcomes between patients with STEMI and those with NSTEMI. Methods: A prospective comparative study was conducted at Community Based Medical College, Bangladesh, from January 2024 to December 2024. A total of 100 hospitalized AMI patients (50 STEMI, 50 NSTEMI) were included. Data on demographics, clinical presentation, treatments, and outcomes were analyzed using SPSS version 23.0. Results: The study included 100 AMI patients (50 STEMI, 50 NSTEMI) with a mean age of 58.2 years. STEMI patients were younger (p = 0.012) with higher smoking rates (p = 0.028). Diabetes was more common in NSTEMI (p = 0.042). STEMI patients presented more with chest pain (p = 0.024) and received more primary PCI (p < 0.001). In-hospital mortality was 10% vs 6% (p = 0.179), with higher MACE in STEMI (p = 0.042). STEMI showed higher troponin (p = 0.013), lower LVEF (p = 0.031), and longer hospitalization (p = 0.038). Conclusion: STEMI patients presented with more severe biochemical and echocardiographic markers, required more invasive interventions, and had worse short-term outcomes despite younger age. Tailored management strategies are needed to mitigate disparities inoutcomes.
