Abstract Objective To explore the effect and possible mechanism of Shensong Yangxin on myocardial microcirculation in rabbits with myocardial infarction. Methods Thirty 6-month-old SPF grade Japanese large ear rabbits were randomly divided into the Sham group, Control group and MI+SSYX group via random number table method, with 10 rabbits in each group. Each group consists of equal number of male and female rabbits. Rabbit models with myocardial infarction in Control group and MI+SSYX group were established by ligation of left anterior descending coronary artery. Rabbits in Sham group were applied stitches under the coronary artery without ligation. After the surgery, rabbits in MI+SSYX group were administered 0.4 g/(kg·d) of Shensong Yangxin dissolved in saline. The Sham group and Control group were treated with the same dose of saline. After 4 weeks of administration, the rabbits of each group were sacrificed and CD34 in the peripheral area of myocardial infarction was tested by immunofluorescence staining to measure the microvessel density. The plasmic levels of endothelin-1 (ET-1), thromboxane A2 (TXA2), nitric oxide (NO) and von Willebrand factor (vWF) were examined by enzyme-linked immunosorbent assay (ELISA). Results Compared with Sham group, the microvessel density were significantly decreased in Control group and MI+SSYX group(P < 0.05); compared with the Control group, the microvessel density was significantly increased in MI+SSYX group(P < 0.05). Compared with Sham group, the plasmic levels of ET-1, NO, TXA2 and vWF in Control group and MI+SSYX group were significantly increased (P < 0.05); compared with Control group, the plasmic levels of ET-1, TXA2, vWF were decreased and the level of NO was increased in MI+SSYX group (P < 0.05). Conclusion Shensong Yangxin can improve myocardial microcirculation in rabbits with myocardial infarction. The mechanism may be related to the functions that Shensong Yangxin can promote the generation of capillary in the boundary of myocardial infarction and balance the endothelial-derived vasodilators and vasoconstrictors.
