背景：本研究旨在(1)评估三维超声心动图（3DE）得出的右心室射血分数（EF）的预后价值；(2)评估降低和保留的左心室射血分数和RVEF在预测大队列心脏病患者全因死亡率和心脏性死亡中的相对预后重要性。方法：采用3DE法对394例不同类型心血管疾病患者进行左室、右室容积和心功能评分。患者分为4组：(1)LVEF正常（>= 50%）和RVEF正常（>= 45%），n = 183；(2)降低LVEF (= 45%), n = 75；(3) LVEF正常（>= 50%），RVEF降低(
Background: The study aimed (1) to assess the prognostic value of three-dimensional echocardiography (3DE) derived right ventricular (RV) ejection fraction (EF) and (2) to evaluate relative prognostic importance of reduced and preserved left ventricular (LV) EF and RVEF to predict all-cause mortality and cardiac death in a large cohort of patients with cardiac diseases.Methods: LV and RV volumes and EF were assessed by 3DE in 394 patients with various cardiovascular diseases. Patients were divided into four groups: (1) normal LVEF (>= 50%) and normal RVEF (>= 45%), n = 183; (2) reduced LVEF (= 45%), n = 75; (3) normal LVEF (>= 50%) and reduced RVEF (
