Abstract:
Objective: To investigate the syndrome property of myocardial Ischemic, and evaluate the relevant informations of qi-deficiency. Methods: SD rats were subjected to either proximal LAD ligation or sham operation. The respiratory rate in both resting state and post-stress were counted. 20 rats (10 in each group) were subjected to forced swimming test (FST) to measure the exhaustive swimming time in every time point Echocardiography was used to evaluate the cardiac function in rats at each time point. Results: Compared with sham operation group, the respiratory rate in the resting state was slower, but faster under post-stress, the exhaustive swimming time was shorter, and the cardiac function of rats was significant decreasing in model group during the period from 7th day to 60th day after operation. The exhaustive swimming time was much shorter, and the relevant information of blood stasis was abnormal in the model group during the period from 7th day to 28th day after operation, when compared with the sham group. Conclusion: Myocardial ischemic rats induced by LAD ligation had both qi-deficiency and blood stasis indications, can be diagnosed as the syndrome of qi-deficiency and blood stasis during the period from 7th day to 28th day after operation. The model rats only had the qi-deficiency indications during the period from 45th day to 60th day after operation, so can be diagnosed as the qi-deficiency syndrome.
