IN-HOSPITAL OUTCOMES OF PATIENTS PRESENTING WITH ANTERIOR WALL MYOCARDIAL INFARCTION WITH RIGHT BUNDLE BRANCH BLOCK

Abstract

BACKGROUND: Acute myocardial infarction is a common heart disease associated with signicant morbidity and mortality. Data on the Clinical, Electrocardiographic and Angiographic prole of acute anterior wall ST-elevation myocardial infarction with Right Bundle Branch Block with q waves in leads v1, v2 are scarce. The aim of this study is to compare the mortality and in hospital outcomes of patients with anterior wall myocardial infarction with RBBB and without RBBB. The study design is a METHODS: retrospective study among the patients admitted with acute anterior wall STEMI with qRBBB and non qRBBB pattern on ECG during the time period March to August 2022. All relevant clinical and treatment data were collected from the medical records department, Government Royapettah Hospital. ECGs taken during the hospitalization of the patient were subjected to detailed analysis and their outcomes were recorded. RESULTS: Among the 50 patients with anterior wall myocardial infarction 11 patients presented with qRBBB pattern. Out of these 11patients, 7 patients had higher Killip score at presentation and 4 of them succumbed to death (57%).The in-hospital mortality rate was higher among those who had anterior wall myocardial infarction with qRBBB pattern when compared to non qRBBB pattern. There was a higher incidence of cardiogenic shock (54%) among patients with qRBBB pattern. Acute anterior wall MI wit CONCLUSION: h qRBBB myocardial infarction is a severe form of acute coronary syndrome with higher in-hospital mortality and morbidity necessitating early recognition and prompt institution of reperfusion therapy. Cardiogenic shock, ventricular tachycardia, higher Killip and TIMI scores at presentation are signicant predictors of inhospital mortality
