Key result
Radionuclide right ventricular ejection fraction was the most powerful independent predictor of cardiovascular death (RR 2.05; 95% CI 1.29-3.26; P=0.002) in patients with stable LVSD.
Why the study?
Do right ventricular systolic function parameters (RVEF, TAPSE, STr) predict cardiovascular death in patients with stable left ventricular systolic dysfunction?

May refine prognostication in stable LVSD; leaves open prospective validation against other RV parameters.
Cohort (n=527)
Do right ventricular systolic function parameters (RVEF, TAPSE, STr) predict cardiovascular death in patients with stable left ventricular systolic dysfunction?
Effect estimate: RR 2.05 (95% CI 1.29-3.26)
p-value: p=0.002
Radionuclide RVEF is the most powerful right ventricular systolic parameter for predicting cardiac survival in patients with stable LVSD, and its predictive value is further improved when combined with STr.
Groote et al. (2012) conducted a cohort in Stable left ventricular systolic dysfunction (LVSD) (n=527). Radionuclide right ventricular ejection fraction (RVEF) vs. EchoDoppler parameters (TAPSE and STr) was evaluated on Cardiovascular death (RR 2.05, 95% CI 1.29-3.26, p=0.002). Radionuclide right ventricular ejection fraction was the most powerful independent predictor of cardiovascular death (RR 2.05; 95% CI 1.29-3.26; P=0.002) in patients with stable LVSD.
