采用UCG评价两组治疗前及治疗4周后的左心室射血分数(left ventricular ejection fraction, LVEF),并比较两组心功能分级的改变. 结果:治疗后,对照组LVEF由0.42±0.08增加至0.49±0.

较低的左心室射血分数 LVEF ; left ventricular ejection fraction
初期的筛分终点是12个月的左心室射血分数和左心室收缩末期容积。
The primary end points were the left ventricular ejection fraction and left ventricular end-systolic volume at 12 months.
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.
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.
