试验设计、设定与病人多中心随机对照试验，2331名医学上稳定的门诊心衰患者，左心室射血分数小于等于35%。
Design, Setting, and patients Multicenter, randomized controlled trial among 2331 medically stable outpatients with heart failure with left ventricular ejection fraction of 35% or less.
这一发现与患者的左心室射血分数——衡量左心室功能的一项参数——无关。
This finding applied to patients irrespective of their left ventricular ejection fraction, a common measure of ventricular function.
目的评价实时三维超声心动图(RT 3de)测量左心室容量与射血分数的准确性。
Objective To assess the accuracy of real-time three-dimensional echocardiography (RT-3DE) for measuring left ventricular volume and ejection fraction.
