Acute Anterior Wall Mi; In-Hospital Mortality With and Without RBBB

Objectives: To compare the frequency of in-hospital mortality of anterior wallmyocardial infarction with and without right bundle branch block. Study Design: Cohort Study.Setting: Cardiology Department of Faisalabad Institute of Cardiology, Faisalabad. Duration:1st September, 2013 to 28th February, 2014. Methodology: 80 patients including both gendersfulfilling the inclusion criteria were collected. Informed consent was obtained from the patients.Effect modifiers such as hypertension, diabetes mellitus, hyper-lipidemia and smoking werenoted. Patients were monitored according to the hospital protocol and mortality was noted.Results: Out of 80 patients, 62(77.5%) were males and 18(22.5%) were females. Smokingwas present in 45% patients, diabetes mellitus in 35% patients, hypertension in 27.5% patientsand hyper-lipidemia in 23.8% patients. In hospital mortality in group A was 23(57.5%) and ingroup B was 7(17.5%) with P value of 0.0001. Conclusion: Acute anterior wall myocardialinfarction combined with right bundle branch block suggests the severity of disease and is anindependent predictor of increased mortality. RBBB after myocardial infarction suggests poorprognosis.
