笔者采用心导管技术观察生脉注射液对家兔急性心肌缺血左室舒张功能的影响。结果表明：心肌缺血可引起左室舒张终末期压（Ｌｖｅｄｐ） 明显升高，左心室舒张期压力下降最大变化速率（ － ｄｐ／ｄｔ） 明显减小。而静脉注射生脉注射液后，可使Ｌｖｅｄｐ 明显降低，－ ｄｐ／ｄｔ 明显增加。从而提示此方剂可改善由缺血而致的左心室舒张功能的不足。
The authors used cardiac catheterization to observe the effect of Shengmai Injection on left ventricular diastolic function in rabbits with acute myocardial ischemia. The results showed that: myocardial ischemia can cause left ventricular end-diastolic end-diastolic pressure (Lvedp) significantly increased, left ventricular diastolic pressure decreased the maximum rate of change (-dp/dt) significantly reduced. Intravenous injection of Shengmai injection can significantly reduce the Lvedp, -dp/dt significantly increased. This suggests that this formula can improve the deficiency of left ventricular diastolic function caused by ischemia.
