研究背景右心室功能障碍被认为是左心衰竭（HF）的主要预后因素。然而，射血分数保留（HFpEF）与射血分数降低（HFrEF）的HF中RV功能障碍的相对贡献尚不清楚。通过超声心动图测定657例年龄和性别匹配的HFpEF患者的三尖瓣环平面收缩期位移（TAPSE）和肺动脉收缩压（PASP）[左心室射血分数（LVEF）>=百分之五十; n=219]和HFrEF（LVEF
Background Right ventricular (RV) dysfunction is recognized as a major prognostic factor in left-sided heart failure (HF). However, the relative contribution of RV dysfunction in HF with preserved (HFpEF) vs. reduced ejection fraction (HFrEF) is unclear.Methods and results Right ventricular longitudinal strain (RVLS), tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP) were determined by echocardiography in 657 age-and gender-matched groups of patients with HFpEF [ left ventricular ejection fraction (LVEF) >= 50%; n=219] and HFrEF (LVEF
