FREQUENCY OF RIGHT VENTRICULAR INFARCTION AMONG PATIENTS PRESENTING WITH ACUTE INFERIOR WALL MYOCARDIAL INFARCTION

Objective: To determine the frequency of right ventricular infarction among patients with acute inferior wall myocardial infarction. Study Design: Descriptive cross sectional study. Place and Duration of Study: Ayub Teaching Hospital, Abbottabad from, Jan 2017 to Sep 2017. Methodology: A total of 163 patients aged 18-75 years and admitted to coronary care unit (CCU) with first attack of acute inferior wall myocardial infarction, were recruited through non probability purposive sampling. Electrocardiogram and Echo were performed of all patients and their findings were noted for the frequency of right ventricular infarction in acute inferior wall myocardial infarction. Results: There were 117 (72%) males and 46 (28%) females. Patients were stratified according to their age in four groups i.e. 13 (8%) patients were less than 40 years of age, 26 (16%) patients were aged between 41 and 50 years, 46 (28%) patients were aged between 51 and 60 years of age and 78 (48%) patients were above 60 years of age. Mean ± SD was 60 ± 1.28. Out of 163 patients, 44 (27%) had right ventricular infarction while 119 (73%) did not have right ventricular infarction. Conclusion: The frequency of right ventricular infraction among patients presenting with acute inferior wall myocardial infarction was 27%.
