Objective To observe the clinical efficacy of Xinkang Decoction in patients with chronic heart failure（CHF）， and to explore the clinical efficacy of treatment by regulating Lung. Methods 120 cases of patients with chronic heart failure were randomly divided into two groups， The control group（n=59） received conventional treatments. Besides the conventional treatments， the treatment group members were given Xinkang Decoction. The course of treatment was 12 weeks. These indicators were observed before and after the treatment including the plasma BNP level， left ventricular ejection fraction（LVEF）， left ventricular end diastolic diameter （LVEDd）， and the score of clinical therapeutic effect. Results The improvement of cardiac function classification， the level of brain natriuretic peptide and ejection fraction in treatment group were better than those of control group（P<0.05）. Conclusion Xinkang Decoction in the treatment of congestive heart failure can better relieve heart failure clinical symptoms， improve left ventricular ejection fraction and reduce the levels of plasma BNP. Therefore， treatment by regulating Lung can significantly improve the clinical efficacy in patients with CHF.
