Right ventricular systolic dysfunction in patients with severe ischemic cardiomyopathy - CMR insights into an interventricular relationship
Background Right ventricular systolic dysfunction is associated with worsened outcomes and poor survival in patients with heart failure. However, it is unclear what mechanisms, other than the presence of RV infarction, contribute to the development of RV dysfunction in patients with severe ischemic cardiomyopathy. We sought to determine the impact of baseline demographic variables, CAD severity, LV diastolic function assessed by echocardiography, ventriculovascular coupling, LV remodeling, aortic biomechanical properties, and RV infarction, assessed by CMR, on RV ejection fraction.
