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

Abstract

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.

Clinical profiling of right ventricular infarction in patients with acute inferior wall myocardial infarction

“…18 George et al, found mortality rate to be 12% in patients with inferior wall myocardial infarction and significantly higher at 28% in patients having right ventricular involvement in inferior wall myocardial infarction cases. 21 Memon AG et al, reported more than double in-hospital mortality in RVMI Group as compared to without RVMI. 19…”

Technical Modifications in the Repair of Acute Ischemic Posterior Ventricular Septal Defect Without Ventriculotomy

“…The present case series is notable for the lack of operative mortality associated with repair of a mechanical complication of an acute inferior wall myocardial infarction. This is a clinically important finding which is highlighted when the outcomes are compared to those from a study by George and colleagues in which acute inferior wall myocardial infarction without mechanical complication resulted in a mortality rate of 12% to 28%, depending on whether there was associated right ventricular involvement . A common cause of death was cardiogenic shock.…”

Factors associated with long-term prognosis in patients with myocardial infarction of the right ventricle, evaluated by the kaplane-meyer method

“…Це зумовлює відсутність єдиної думки щодо самостійного впливу ІМ ПШ на підвищення ризику фатальних ускладнень та смерті, що спонукає до подальших досліджень в цьому напрямку. Ряд клінічних випробувань пере-конливо демонструє підвищення числа ускладнень і смертності хворих при бівентрікулярному ІМ в го-строму періоді і віддаленій перспективі в порівнянні з ізольованим ураженням ЛШ [4,5]. Їм суперечать дослідження, які пов'язують високий ризик неспри-ятливого прогнозу не стільки з ІМ ПШ, скільки з поширеністю некрозу ЛШ [6,7].…”
