Effect of xinmaitong capsule on total ischemia burden in coronary heart disease patients with myocardial ischemia and analysis of its therapeutical mechanism

Abstract

OBJECTIVE: To assess the effect of Xinmaitong (XMT) capsule in treating ischemical cardiac disease. METHODS: Sixty coronary heart disease (CHD) patients with myocardial ischemia were divided randomly into two groups. XMT group (30 cases) was treated with XMT plus western medicine, and control group (30 cases) with western medicine alone. The changes of the scores for clinical symptoms, the total ischemia burden (TIB), the plasma endothelin (ET), the nitric oxide (NO), the superoxide dismutase (SOD), and the malonyldialdeyde (MDA) levels were observed before and after treatment. RESULTS: After treatment with XMT the scores of clinical symptoms, TIB, ET and MDA levels were significantly decreased (P < 0.01), the levels of NO and SOD were significantly increased (P < 0.01) in the XMT group, comparing with the control group these changes were statistically different (P < 0.01). CONCLUSIONS: XMT capsule can act against myocardial ischemia effectively, one of the mechanisms of which is protecting the function of vascular endothelium and resisting lipid peroxidation injury. The effects of adding XMT capsule on conventional treatment of western medicine were better than those of using western medicine alone.
