Study of Qiliqiangxin Capsule to Treat Dilated Cardiomyopathy

A Multi-center, Randomized, Double, Placebo-controlled, Parallel Group Study of Improving Heart Function and Immunoregulation Effects of Qiliqiangxin Capsule in Patients With Dilated Cardiomyopathy

The pathogenesis of dilated cardiomyopathy (DCM) leading to heart failure is closely associated with autoimmunity dysfunction. A few studies represented that Qiliqiangxin capsule, a Chinese medicine, could enhance heart function in chronic heart failure and regulate the balance of TNF-a and IL-10 in myocardial infarction. In this study, to explore the effects of Qiliqiangxin capsule on the improving heart function and immunoregulation in patients with DCM, patients were recruited, anti-heart autoantibodies and some representative cytokines were assayed by enzyme-linked immuno sorbent assay (ELISA), and the efficacy of heart function improvement was compared between Qiliqiangxin capsule and placebo under the standard treatment of DCM.
