Objective

2

To observe the protective effect of Huangqi Guizhi Wuwutang combined with Shengmaiyin on the heart function in patients with diabetic cardiomyopathy and explore its anti-myocardial fibrosis and anti-inflammatory effects.

Method

2

The 96 patients were randomly divided into observation group （48 cases） and control group （48 cases）. Both groups were given comprehensive measures to control blood sugar， blood lipids， blood pressure and heart failure. Patients in control group took Tongmai Jiangtang capsule， 3 granules/time， 3 times/day. Patients in observation group took Huangqi Guizhi Wuwutang combined with modified Shengmaiyin， 1 dose/day. The treatment courses were three months in both groups. Left ventricular ejection fraction （LVEF）， early diastolic peak velocity E peak/late diastolic peak velocity A peak （E/A）， left ventricular end diastolic diameter （LVEDd） and cardiac output per stroke （SV） through echocardiography were recorded before and after therapy. Cardiac troponin-I （cTn I）， troponin T （cTn-T）， creatine kinase isoenzyme -MB （CK-MB）， lactate dehydrogenase （LDH）， transforming growth factor-

Conclusion

2

On the basis of conventional intervention of western medicine， Huangqi Guizhi Wuwutang combined with modified Shengmaiyin has anti-inflammatory and anti-myocardial fibrosis effects， with inhibitory effect on myocardial remodeling， and can reduce myocardial tissue damage to improve ventricular diastolic function and protect heart function. With such high clinical efficacy， it is worthy of clinical use.
