  1. This finding applied to patients irrespective of their left ventricular ejection fraction, a common measure of ventricular function

    這一發現與患者的左心室射血分數? ?衡量左心室功能的一項參數? ?無關。
  2. Methods : fifty - one systolic hf patients with left ventricular ejection fraction ( lvef ) < 40 % were randomly assigned to receive 1 - year treatment of candesartan and spironolactone ( combination group ) or candesartan and placebo ( control group )

    方法： 51名左室射血分數（ lvef ） < 40 %的收縮性心力衰竭患者隨機分配到接受坎地沙坦和螺內酯治療1年（聯合治療組）或坎地沙坦和安慰劑治療（對照組） 。
  3. The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases, low left ventricular ejection fraction, and so on. like other risk predictors, measures of heart rate variability have modest positive predictive accuracy when used alone. however, combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 %

    心率變異性的預測價值獨立於其他非創傷性預測心臟疾病預后指標（降低的左心室射血分數，頻發重復性室性心律失常等） ，在單獨應用時陽性預報率較低，但與其他指標聯合應用，陽性預報率可達50 。
  4. Left ventricular end - diastolic pressure is a predictor of ortality in cardiac surgery independently of left ventricular ejection fraction

    左室舒張末壓是心臟手術患者死亡率的一個預測因素，它不依賴於左室射血分數。
  5. Correlation studies of heart rate variability, ventricular late potential, qt dispersion and left ventricular ejection fraction in coronary heart disease patients

    間期離散度及左室射血分數相關性研究
  6. Left ventricular ejection fraction ( lvef ) was reported in two thirds of the group, among whom half had preserved systolic function, defined lvef 45 %

    本組患者中三分之二的人左心室射學分數（ lvef ） 45 % ，其中半數的患者擁有儲備收縮功能。
  7. Patients with above - median mpo levels in combination with above - median plasma amino - terminal pro - brain natriuretic peptide ( nt - probnp ) or below - median left ventricular ejection fraction ( lvef ) had significantly greater mortality compared with other patients

    在mpo中位數以上水平伴血漿氨基末端前腦利鈉肽中位數水平以上病人或左心室射血分數在中位數以下病人相對于其他病人有更高的死亡率。
  8. Recently it was reported that intravenous il - 2 could reduce left ventricular ejection fraction

    目前對il - 2是否能通過中樞對心血管系統起作用知之甚少。
