麝香保心丸对心肌梗塞后左室形态和功能影响的实验研究

目的：观察麝香保心丸对心肌梗塞后大鼠左室形态及功能的影响。方法：结扎冠状动脉复制大鼠心梗模型、随机分为心梗对照组、麝香保心丸组及开搏通治疗组。2周及6周时测量血动学参数及心功能，同时研究左室形态学参数（左心腔面积、梗塞区室壁变薄比及左室伸展指数）。结果：麝香保心丸可减少梗塞后6周大鼠的左室扩张及梗塞区伸展；明显改善心梗后左室收缩功能。结果提示：麝香保心丸可改善心肌梗塞后的左室重构。

Experimental Study on Effect of Shexiangbaoxin Pills on Morphosis and Function of Left Ventricle after Myocardial Infarction in Rat

Objective: To investigate the effect of Shexiangbaoxin Pills on morphosis and function of left ventricle after myocardial infarction in rat. Methods: The rat myocardial infarction models induced by ligaturing coronary artery were randomly divided into the myocardial infarction control group, Shexiangbaoxin Pill group and captopril group. The hemodynamic parameters and cardiac functions in 2 or 6 weeks after treatment were determined. Meantime, the morphological parameters of left ventrile (left cardiac chamber size, attenuation proportion of ventricular wall of infarction area, and expansion index of left ventrile), were studied. Results: Shexiangbaoxin Pills could reduce the distention of left ventrile and expansion of infarction area of rat in 6 weeks after infarction. It could obviously improve the contraction function of left ventrile after myocardial infarction. Conclusion: Shexiangbaoxin Pills can improve left ventricular reconstitution after myocardial infarction.
