Clinical efficacy and safety of nuanxin capsule for chronic heart failure

摘要

Background:Chronic heart failure (CHF), the final phase of various heart diseases, is a serious public health problem resulting in high hospitalization rates, mortality, and increasing health care costs. Nuanxin capsule (NXC), a Chinese herbal formula, has been widely used in the treatment of CHF. However, the safety and efficacy of NXC used in patients with CHF has been uncertain and there has been no standard clinical trial published to confirm this. Thus, we conduct a study to evaluate the safety and efficacy of NXC for CHF.
