Why the study?
Does RVEF determined by CMR predict cardiovascular outcomes independent of LVEF in patients referred for CMR?
Does RVEF determined by CMR predict cardiovascular outcomes independent of LVEF in patients referred for CMR?
RVEF determined by CMR is an independent predictor of adverse cardiovascular outcomes, including death and worsening heart failure, in patients referred for CMR.
Although studies have shown that right ventricular ejection fraction (RVEF) is an independent predictor of survival in patients with myocardial infarction and moderate left heart failure, there is scant data available on the prognostic significance of RVEF in patients with preserved left ventricular ejection fraction (LVEF), partly due to challenges in imaging the right ventricle (RV) due to its amorphous geometry. Recent technological advances in cardiac magnetic resonance (CMR) have allowed the RVEF to be assessed with greater accuracy.
