Key result
Patients with acute inferior wall myocardial infarction and right ventricular infarction had a higher but non-statistically significant rate of in-hospital mortality compared to those without right ventricular infarction (10.0% vs 4.4%, p=0.150).
Why the study?
Does the presence of right ventricular infarction increase in-hospital mortality in hospitalized patients with acute inferior wall myocardial infarction?
Cohort (n=180)
No
Does the presence of right ventricular infarction increase in-hospital mortality in hospitalized patients with acute inferior wall myocardial infarction?
Absolute Event Rate: 10% vs 4.4%
p-value: p=0.150
Right ventricular involvement in acute inferior myocardial infarction is associated with a numerically higher, though not statistically significant, in-hospital mortality.
No significant mortality difference with RV infarction in inferior MI; leaves open need for larger studies to clarify prognostic impact.
Objectives: To compare the frequency of mortality in hospitalized patientswith acute inferior wall myocardial infarction with or without right ventricular infarction. StudyDesign: Cohort study. Setting: Faisalabad Institute of Cardiology, Cardiology Department.Period: 2013-2014. Materials and Methods: 180 patients of acute inferior wall myocardialinfarction were included after obtaining informed consent. Group A (exposed) had acuteinferior wall myocardial infarction with right ventricular infarction and group B (un exposed) hadpatients 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 Hypertension25(27.8%), Diabetes Mellitus 35(38.9%), Smoking 40(44.4%) and Dyslipidemia 13(14.4%). Ingroup 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 groupB(un Exposed) was 4(4.4%). Conclusion: The mortality with inferior wall MI with right ventricleinfarction was higher than patients without right ventricle infarction, although no statisticaldifference was found.

Shahid Abbas (2017) conducted a cohort in Acute inferior wall myocardial infarction (n=180). Right ventricular infarction vs. No right ventricular infarction was evaluated on In-hospital mortality (p=0.150). Patients with acute inferior wall myocardial infarction and right ventricular infarction had a higher but non-statistically significant rate of in-hospital mortality compared to those without right ventricular infarction (10.0% vs 4.4%, p=0.150).
