Association of Mortality in Patients with Right Bundle Branch Block in Patients Presented withAnterior Wall Myocardial Infarction during Hospital Stay
Abstract
Objective: To determine the association of mortality with right bundle branch block in individuals presenting with acute anterior wall myocardial infarction during hospital stay.Methods
This Cohort study was done in Department of Cardiology, University of Lahore hospital, Lahore during September 2022 to March 2023. Sample size of 160 individuals; 80 in each group were enrolled. Then, ECG will be performed at admission and individuals were divided in two groups i.e. exposed and unexposed. During follow-up, it patient died within hospital stay, then in-hospital mortality was labeled. Data was collected in proforma and analysed in SPSS version 25.Results
In exposed group, the mean age of individuals was 47.51 ± 10.56 years and in unexposed group was 49.99 ± 12.82 years. In exposed group, there were 36 (45.0%) males and 44 (55.0%) females. In unexposed group, there were 33 (41.3%) males and 47 (58.8%) females. In exposed group, 17 (21.3%) individuals died during hospital stay. In unexposed group, 5 (6.3%) individuals died during hospital stay. There is significant association exist between right bundle branch block and in-hospital mortality i.e. Relative risk = 1.693, 95% confidence interval = 1.266, 2.264, p-value = 0.006).Conclusion
Thus, there is a significant association of right bundle branch block with mortality in individuals with acute anterior wall STEMI.Keywords:
