Insights
Three-dimensional echocardiography-derived right ventricular ejection fraction (RVEF) is a strong predictor of cardiac events in patients with ischemic and dilated cardiomyopathy. This measurement offers valuable risk stratification beyond traditional echocardiographic parameters.
Area of Science:
- Cardiology
- Echocardiography
- Cardiovascular Imaging
Background:
- Limited data exists on the prognostic significance of three-dimensional echocardiography (3DE)-derived right ventricular ejection fraction (RVEF) in ischemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM).
- Assessing RV function is crucial for managing heart failure patients.
Purpose of the Study:
- To evaluate the prognostic value of 3DE-derived RVEF in patients with ICM and DCM.
- To determine if RVEF provides incremental prognostic information beyond conventional echocardiographic measures.
Main Methods:
- Retrospective analysis of 120 ICM and 107 DCM patients who underwent 3DE.
- Utilized 3DE speckle tracking software for RVEF assessment.
- Primary endpoint: composite of cardiac death, heart failure hospitalization, myocardial infarction, or ventricular tachyarrhythmia.
Main Results:
- RVEF was significantly associated with cardiac events in both ICM and DCM groups (Univariate and Multivariable analysis).
- RVEF demonstrated independent prognostic value after adjusting for clinical factors and LV parameters.
- Kaplan-Meier analysis showed significant risk stratification based on RVEF and E/e' levels.
Conclusions:
- 3DE-derived RVEF is an independent and incremental predictor of cardiac events in ICM and DCM.
- RVEF, combined with E/e', allows for detailed risk stratification in these patient populations.
Background:
There 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).
Methods:
120 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.
Results:
During 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.
Conclusions:
This 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'.
