Purpose : This topic on the basis of demonstrated stable angina pectoris ( Qi Deficiency Syndrome ) basic pathogenesis and Qi Governing Law observed SFI angina pectoris qi deficiency symptoms and plasma ET levels to explore some of its clinical mechanism . Methods: The study included a total Deficiency angina pectoris 60 patients were randomly divided into a treatment group of 30 patients in the control group of 30 patients . Was no significant difference between the two groups in terms of age, gender, disease duration , disease and clinical general information . Treatment group to SFI , the control group to Shen Mai injection therapy, the treatment was observed after treatment before clinical symptoms and test indicators of the level of plasma ET . Results: angina pectoris patients treated with total efficiency ECG were 93.3% , 73.3% , 90.0% better than the control group , 63.3 % , but did not reach statistical significance ( P GT ; 0.05 ) . In terms of clinical symptoms in both groups improved the Deficiency angina chest tightness, chest pain, heart palpitations , shortness of breath and other primary and secondary disease manifestations, the clinical symptoms in the two groups showed no significant difference ( P gt ; 0.05 ) Endothelial function after treatment were higher than those of the two groups of ET decreased, a significant difference ( P lt ; 0.01 ) compared with before treatment , improve the role of ET on the two groups showed no statistical significant difference ( P GT ; 0.05). Adverse reaction was not observed to a significant or adverse reactions have serious consequences . Conclusion: Effects of Shenqifuzheng injection treatment of stable angina pectoris ( Deficiency ) efficacy, its efficacy may be the mechanism by improving myocardial ischemia in patients with angina , the regulation of endothelial function and role , is a safe and effective formulations , it is worth further study .
