BackgroundHeart failure (HF) is the end stage of many heart diseases, and ischemic heart disease (IHD) is the primary cause. Yiqi Fumai lyophilized injection, a contemporary Chinese medicine preparation, widely used in the treatment of IHF patients, shows clinical efficacy on improving symptoms and cardiac function, but the quality of the current literature does not address multiple important issues. This article describes a protocol for assessment of complementary treatment with Yiqi Fumai lyophilized injection in acute decompensated IHD.MethodsThe protocol is designed as a multicenter randomized controlled trial to assess the efficacy and safety of complementary treatment with Yiqi Fumai lyophilized injection on acute decompensated IHD. This trial will be carried out in 37 hospitals in China and expected to enroll 666 inpatients with acute decompensated IHF due to coronary heart disease. On the basis of standardized western medications, patients are randomized to either the treatment group (250 ml 5% glucose / sodium injection + 5.2 g Yiqi Fumai lyophilized injection) or the control group for 7 days and follow-up for 30 ± 3 and 60 ± 3 days. The primary outcome is change in brain natriuretic peptide (BNP) concentrations. The secondary outcomes are composite endpoint, left ventricular ejection fraction, blood troponin T/I, cardiothoracic ratio, life quality scale, scores of the four traditional Chinese medicine (TCM) diagnostic methods.DiscussionStandardized western medications together with TCM have been extensively used in China and have developed into a comprehensive treatment model. The trial will provide clinical research evidence for application of complementary treatment with intravenous Yiqi Fumai lyophilized injection on decompensated IHF.Trial RegistrationThis study protocol has been listed in the Chinese Clinical Trial Registry (registration number: ChiCTR-IPR-15007396, http://www.chictr.org.cn/showproj.aspx?proj=12370) on November 6, 2015.
