Clinical Profile and In-Hospital Outcome of Patients with Right Ventricular Myocardial Infarction


Objectives: Right ventricular myocardial infarction as assessed by various diagnostic methods accompanies inferior wall myocardial infarction in 30% to 50% of patients. Acute right ventricular myocardial infarction is associated with higher in-hospital morbidity and mortality related to life-threatening hemodynamic compromise and arrhythmias. Since there is scarcity of literature regarding epidemiology of clinical profile as well as in-hospital outcomes of patients with right ventricular myocardial infarction in the Indian population, this study is carried out with a goal of identifying the same in our hospital setting, to fulfill this void. Methods: We examined the incidence of risk factors in patients (n = 100) with inferior wall myocardial infarction and 100 patients with inferior wall myocardial infarction having right ventricular involvement. Results: The mortality rate was found to be 12% in patients with inferior wall myocardial infarction and 28% in patients having right ventricular involvement in inferior wall myocardial infarction. Conclusions: From the above study, it can be concluded that patients with inferior wall myocardial infarction who have right ventricular myocardial involvement are at an increased risk of death, and cardiogenic shock.
