Comparison of In-Hospital Outcomes of Anterior Wall Versus Inferior Wall ST Elevation Myocardial Infarction Following Percutaneous Coronary Intervention: A Descriptive Cross-Sectional Study

Abstract

Introduction ST-elevation myocardial infarction (STEMI) is a critical condition affecting many individuals worldwide, posing significant risks to patient health and outcomes. Different types of STEMI, such as anterior wall and inferior wall STEMI, can lead to varying in-hospital outcomes following percutaneous coronary intervention (PCI). Understanding these differences is crucial for improving patient care and treatment strategies. This study aimed to compare the in-hospital outcomes of anterior and inferior wall STEMI in patients undergoing PCI at a tertiary care center.  Methods This descriptive cross-sectional study included 70 patients who underwent PCI for either Anterior or inferior wall STEMI at Chitwan Medical College Teaching Hospital ( CMCTH) and were admitted to the Critical Care Unit (CCU) from February 5th 2021 to March 4th 2022. Anterior wall or inferior wall STEMI was diagnosed using a surface Electrocardiogram (ECG) and in-hospital outcomes were recorded using structured Proforma. Data was entered and analyzed with SPSS-26.  Results Among the 70 patients included in the study, the mean age was 64.50 ± 9.818 years. The majority (77.1%) of patients were male and 22.9% of the patients were female. Among the patients of anterior wall MI who underwent PCI, 11 patients (15.7%) had cardiogenic shock, 21 patients (30.0%) had AKI, 2 patients (2.9%) had CVA, and 2 patients (2.9%) had death.  Conclusion Patients with anterior wall STEMI following PCI had worse in-hospital outcomes compared to those with inferior wall STEMI.
