FREQUENCY OF COMPLETE HEART BLOCK IN PATIENTS PRESENTING WITH INFERIOR WALL MYOCARDIAL INFARCTION

Abstract

Objective: To determine the frequency of complete heart block in patients with acute inferior wall myocardial infarction

Methods: Descriptive cross-sectional study conducted in Cardiology Department Khyber Teaching hospital Peshawar from 23 Dec, 2019 to 23 Jun, 2020. Diagnosis of acute inferior wall MI was made. Presence or absence of complete heart block was made with standard 12 lead ECG and continues cardiac monitoring during hospital stay.

 Results:  A total of 233 patients meeting the inclusion criteria were studied. Mean age ±SD of studied population was 63.86±7.180. Patients were divided into two groups based of age. The number of patients less than 60 years of age were 58 (24.9%) while those 60 years and above were 175 (75.1%). 158 (67.8%) patients were males while 75 (32.2%) patients were females. Complete Heart Block (CHB) was recorded in (18.5%) of patients with Acute Myocardial Infarction (AMI). There was no effect of CV risk factors on CHB except age where elderly patients showed significantly higher rates of CHB

Conclusion: CHB is a common complication in patients with inferior wall myocardial high. Aging increases the risk of CHB in inferior STEMI.
