Professional Med J Jan ;23(09):1118-26.

To compare the frequency of in-hospital mortality of anterior wall myocardial 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 genders fulfilling the inclusion criteria were collected. Informed consent was obtained from the patients. Effect modifiers such as hypertension, diabetes mellitus, hyper-lipidemia and smoking were noted. 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. Smoking was present in 45% patients, diabetes mellitus in 35% patients, hypertension in 27.5% patients and hyper-lipidemia in 23.8% patients. In hospital mortality in group A was 23(57.5%) and in group B was 7(17.5%) with P value of 0.0001. Conclusion: Acute anterior wall myocardial infarction combined with right bundle branch block suggests the severity of disease and is an independent predictor of increased mortality. RBBB after myocardial infarction suggests poor prognosis.
