Effects of Right Ventricular Ejection Fraction on Outcomes in Chronic Systolic Heart Failure

Studies of the effect of right ventricular ejection fraction (RVEF) on outcomes in heart failure (HF) are limited by small sample size and short follow-up. We examined the effect of baseline RVEF on outcomes in 2008 Beta-Blocker Evaluation of Survival Trial (BEST) participants with HF and left ventricular ejection fraction or=40% (n=733), 30% to 39% (n=531), 20% to 29% (n=473), and or=40%, 30% to 39%, 20% to 29%, and or=40%, unadjusted hazard ratios and 95% confidence intervals for all-cause mortality for those with RVEF 30% to 39%, 20% to 29%, and
