Key result
Lower RVEF predicts worse survival in moderate CHF, dropping to 59% for severe right ventricular dysfunction.
Why the study?
Right ventricular ejection fraction (RVEF) is known to predict survival in advanced CHF, but its prognostic value in moderate CHF patients needed investigation.
Population
205 consecutive patients with moderate CHF (NYHA class II and III)
Comparison
RVEF levels as predictor of survival
Design
Prospective study with cardiopulmonary exercise testing and radionuclide angiography
Follow-up
Median 755 days

Cohort study demonstrates right ventricular ejection fraction predicts survival in moderate heart failure, indicating the importance of monitoring right heart performance.
Cohort (n=205)
Groote et al. (1998) conducted a cohort in moderate congestive heart failure (n=205). Right ventricular ejection fraction (RVEF) vs. Different RVEF categories (<25%, ≥25% to <35%, ≥35%) was evaluated on Survival and event-free cardiac survival. Right ventricular ejection fraction is an independent predictor of survival in moderate CHF, with 2-year survival rates of 59%, 77%, and 93% for RVEF <25%, 25-35%, and ≥35%, respectively.
