概要	*Poster Session (Japanese)115 Heart Failure (Laboratory/Biomarkers) BACKGROUND: Right ventricular (RV) systolic function and systolic pressure respectively affects prognosis in acute heart failure (AHF) patients with reduced left ventricular ejection fraction (LVEF). We aimed to evaluate the prognostic value of RV systolic function index in combination with RV systolic pressure (RVSP) in AHF patients. METHODS and RESULTS: This observational study included 548 urgently hospitalized AHF patients with reduced LVEF and with full information of tissue Doppler imaging (TDI) echocardiography. ROC curves for all-cause mortality, as the primary endpoint, indicated higher AUC in the ratio of RV-TDI s’ to RVSP, compared to other indices of RV systolic function. When dividing patients into 2 groups by the cut-off value of RV-TDI s’/RVSP (0.21), KaplanMeier analysis showed higher mortality in patients with RVTDI s’/RVSP<0.21 (Figure). In multivariate Cox regression analysis, RV-TDI s’/RVSP<0.21 was an independent predictor of all-cause mortality in AHF patients with reduced LVEF (HR: 2.50 [95%CI: 1.39-4.50]), even after adjustment for confounders.CONCLUSIONS: The ratio of RVTDI s’/RVSP may predict all-cause mortality in AHF patients with reduced LVEF.
