ACUTE INFERIOR MYOCARDIAL INFARCTION;

COMPARISON OF MORTALITY IN HOSPITALIZED PATIENTS WITH OR WITHOUT RIGHT VENTRICULAR INFARCTION

Abstract

Objectives: To compare the frequency of mortality in hospitalized patients
with acute inferior wall myocardial infarction with or without right ventricular infarction. Study
Design: Cohort study. Setting: Faisalabad Institute of Cardiology, Cardiology Department.
Period: 2013-2014. Materials and Methods: 180 patients of acute inferior wall myocardial
infarction were included after obtaining informed consent. Group A (exposed) had acute
inferior wall myocardial infarction with right ventricular infarction and group B (un exposed) had
patients with inferior wall MI without right ventricular infarction. Results: Out of 180 patients,
150(83.3%) were male and 30(16.7%) were female. In group A, patients having Hypertension
25(27.8%), Diabetes Mellitus 35(38.9%), Smoking 40(44.4%) and Dyslipidemia 13(14.4%). In
group B, Diabetes Mellitus present in 26(28.9%), Hypertension 22 (24.4%), Smoking 23(25.6%)
and Dyslipidemia 19(21.1%). In hospital mortality in group A(exposed) was 9(10%) and in group
B(un Exposed) was 4(4.4%). Conclusion: The mortality with inferior wall MI with right ventricle
infarction was higher than patients without right ventricle infarction, although no statistical
difference was found.
