Abstract: Objective: To determine mortality rate associated with inferior wall myocardial infarction with or without atrioventricular block. Design & duration: This is a cohort study completed in duration of six months. Setting: Study was conducted in Cardiology ward of Bahawal Victoria Hospital Bahawalpur Patients & methods: Patients presenting to the study hospital with inferior wall myocardial infarction combined with or without atrioventricular block. Inclusion and exclusion criteria were made for selection of patients. Sample size calculated using WHO sample size calculator. Non-probability consecutive sampling technique was used. Level of significance was 5%. P-value less than 0.05 was considered statistically significant. Consent was taken from all cases for including their data in the study. Permission was also taken from ethical review board committee. Chi square test was applied. SPSS software version 20 was used for analyzing data. Results were calculated in the form of percentage, frequency, means and standard deviation. Results: Total 160 cases were studied. They were divided into two groups. Patients with inferior wall MI having atrioventricular block as well were placed in group-A. Other patients with inferior wall MI without AV block were placed in group-B. Mean age was 53±7.8 years. There were 43.3% male and 57.6% female patients. Majority of cases (66.7%) were above 50 years of age. Mortality in group-A was 18.3% and in group-B 11.7%. Conclusion:Inferior wall myocardial infarction complicated with atrio-ventricular block has high mortality rate as compared to MI without AV block.

Key words: Myocardial Infarction, Atrioventricular block, Mortality.
