The association of right ventricular dysfunction with in-hospital and 1-year outcomes in anterior myocardial infarction

In this study, we evaluated the prognostic effect of RV dysfunction on in-hospital and long-term outcomes in patients with first anterior STEMI. A total of 350 patients without known coronary artery disease with first anterior STEMI and treated with primary percutaneous coronary intervention were prospectively enrolled in this study. In-hospital and long-term outcomes were compared between two groups of with or without RV dysfunction. In-hospital mortality was significantly higher in the RV dysfunction group (26.7% vs. 1.6%, P  <  0.001). The RV dysfunction group also had a higher incidence of cardiogenic shock, recurrent myocardial infarction, target lesion revascularization and stent thrombosis. The 1-year overall survival in patients with and without RV dysfunction was 62.2% and 95.0% respectively. After multivariable a nalysis, RV dysfunction remained as an independent predictor for in-hospital and long-term mortality. RV dysfunction is an independent predictor of cardiogenic shock, recurrent myocardial infarction, and, in-hospital and long-term mortality in anterior STEMI. Therefore, attention should be paid to t he function of right ventricle as in the left ventricle after anterior STEMI.
