| 1. | Recently it was reported that intravenous il - 2 could reduce left ventricular ejection fraction
目前对il - 2是否能通过中枢对心血管系统起作用知之甚少。 |
| 2. | This finding applied to patients irrespective of their left ventricular ejection fraction , a common measure of ventricular function
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。 |
| 3. | Correlation studies of heart rate variability , ventricular late potential , qt dispersion and left ventricular ejection fraction in coronary heart disease patients
间期离散度及左室射血分数相关性研究 |
| 4. | Left ventricular end - diastolic pressure is a predictor of ortality in cardiac surgery independently of left ventricular ejection fraction
左室舒张末压是心脏手术患者死亡率的一个预测因素，它不依赖于左室射血分数。 |
| 5. | Left ventricular ejection fraction ( lvef ) was reported in two thirds of the group , among whom half had preserved systolic function , defined lvef 45 %
本组患者中三分之二的人左心室射学分数（ lvef ） 45 % ，其中半数的患者拥有储备收缩功能。 |
| 6. | During the stu dy period , all rabbits were bled to assay the titers of antipeptide antibody and left ventricular ejection fractions ( lvefs ) were measured by emission computed tomography
实验期间所有动物均抽血测定抗肽抗体效价，并用发射计算机断层摄影法测定左室射血分数。 |
| 7. | 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名左室射血分数（ lvef ） < 40 %的收缩性心力衰竭患者随机分配到接受坎地沙坦和螺内酯治疗1年（联合治疗组）或坎地沙坦和安慰剂治疗（对照组） 。 |
| 8. | 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中位数以上水平伴血浆氨基末端前脑利钠肽中位数水平以上病人或左心室射血分数在中位数以下病人相对于其他病人有更高的死亡率。 |
| 9. | 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 %
心率变异性的预测价值独立于其他非创伤性预测心脏疾病预后指标(降低的左心室射血分数，频发重复性室性心律失常等) ，在单独应用时阳性预报率较低，但与其他指标联合应用，阳性预报率可达50 。 |
