Abstract

Objective: Right ventricular (RV) dysfunction is common in heart failure with reduced left ventricular ejection fraction (HFrEF). Several studies demonstrate that RV dysfunction is an important in prognosis as well as in monitoring and evaluating treatments. RV strain measured by 2D speckle tracking echocardiography (STE) can identify RV dysfunction with high sensitivity and have valuable prognosis in patients with HFrEF. Methods: Right ventricular global longitudinal strain (RVGLS) and right ventricular free wall longitudinal strain (RVFWS) were evaluated with inpatients HFrEF before discharge. The association between these parameters and clinical presentation, others traditional RV assessment was also examined. Cross-sectional study were used. Results: A total 110 HFrEF patients were enrolled, with an average age 61,85, of which male accounted for 61,8%. 81,82% patients concurrent RV dysfunction. The average RVGLS and RVFWS were -10,28 ± 4,53% and 14,41 ± 5,75%, respectively. RVGLS and RVFWS is associated with serum NT-proBNP and others echocardiography parameters (TAPSE, RVs’, RVFAC). Conclusions: RVGLS is valuable modality in detection early RV dysfunction in patients with HFrEF.
