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

ABSTRACT 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. Electro-cardiogram 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%.
