Prognostic value of right ventricular ejection fraction using three-dimensional echocardiography in patients with ischemic and dilated cardiomyopathy.
Article in Journal of echocardiography, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere are few studies reporting the prognostic value of three-dimensional echocardiography (3DE)-derived right ventricular ejection fraction (RVEF) in patients with ischemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM).
methods120 ICM and 107 DCM patients who underwent 3DE were retrospectively selected and analyzed using 3DE speckle tracking software. The primary endpoint was a composite of cardiac events, including cardiac death, heart failure hospitalization, myocardial infarction, or ventricular tachyarrhythmia.
resultsDuring a median follow-up of 24.3 and 53.6 months, 45 patients in ICM and 39 patients in DCM, respectively, reached the primary endpoint. Univariate analysis showed that RVEF was statistically significantly associated with cardiac events in both groups [ICM, hazard ratio (HR): 0.92, 95% confidence interval (CI) 0.89-0.95; DCM, HR: 0.90, 95% CI 0.86-0.93, respectively]. In multivariable analysis, RVEF (HR: 0.89-0.92, p < 0.001) was also statistically significantly associated with cardiac events in both ICM and DCM, even after adjustment for clinical factors, left ventricular (LV) systolic and diastolic parameters, or RV systolic parameters. Kaplan-Meier curves, divided into four groups by RVEF ≥ 45% and < 45% and E/e' ≥ 14 and < 14, showed significant risk stratification for both ICM (p = 0.0068) and DCM (p < 0.0001). RVEF had incremental prognostic value over age, E/e', and conventional RV systolic parameters, in both ICM and DCM.
conclusionsThis study confirms the independent and incremental prognostic value of RVEF over conventional echocardiographic parameters in patients with ICM and DCM and allows detailed risk stratification of cardiac events by RVEF and E/e'.
