The presence of conduction defects complicates AMI frequently and is associated with increased short and long term mortality rates. The occurrence of complete heart block in anterior wall myocardial infarction is important because it indicates that infarction is extensive and may result in cardiac failure or death. Objective: To determine the frequency of complete heart block (CHB) in patients presented with anterior wall myocardial infarction (AWMI). Material and Methods: Total 152 patients

... h AWMI were included. The history of the patients was taken regarding hypertension, diabetes mellitus, smoking, family history of CAD, and chronic kidney disease. Study outcome, complete heart block, was assessed and recorded. Results: There were 81.6% male and 18.4% female patients. Mean age was 56.25±9.81 years. Total 9.2% patients were found with chronic kidney disease. In our study, 12.5% patients were found with complete heart block. Significant association of complete heart block was observed with hypertension and diabetes mellitus while no significant association was observed with gender, age, smoking, CAD family history, and chronic kidney disease. Conclusion: Our study results showed 12.5% patients observed complete heart block. Hypertension and diabetes mellitus are found as the significant risk factors of complete heart block.
