To explore the clinical effectS of Jiawei Danggui Buxue Decoction combined with iron supplementation in the treatment of elderly patients with chronic heart failure and mild anemia，and to analyze its impact on prognosis.Methods:A prospective study was conducted on 60 elderly patients with chronic heart failure and mild anemia in Qinhuangdao City Harbor Hospital from March 2013 to October 2014.They were divided into a control group(n＝30)and an observation group(n＝30)according to random number table method.The control group was treated with iron sucrose，while the observation group was treated with Jiawei Danggui Buxue Decoction on this basis.Both groups were treated continuously for 3 months.The levels of TIBC，SF and TS before and after treatment were counted; the levels of Hb，6MWT and NT-proBNP before and after treatment were recorded; the data of LVEF and LVEDD before and after treatment were recorded; the cardiac function of the 2 groups was graded by NYHA before and after treatment.Results:After treatment，the total clinical effective rate of the observation group was higher than that of the control group.The levels of TIBC，SF and TS in the observation group was higher than before treatment and the control group(P<0.05 or P<0.01).Compared with before treatment，the level of Hb，6MWT in the observation group increased markedly，and was higher than that in the control group(P<0.01); the levels of NT-proBNP in the observation group decreased memorably and was lower than that in the control group(P<0.05 or P<0.01).Compared with before treatment，the level of LVEF in the 2 groups increased dramatically after treatment，and the observation group was substantially higher than that in the control group(P<0.01); after treatment，the level of LVEDD in the observation group decreased markedly，and was dramatically lower than that in the control group(P<0.01).Compared with before treatment，the number of NYHA grade II-III cases in the 2 groups decreased memorably after treatment; and the observation group was significantly lower than that of the control group(P<0.05).Conclusion:Combination of intravenous sucrose iron therapy and routine treatment can effectively relieve the clinical symptoms of CHF patients with mild anemia，improve the cardiac function index，improve the classification of heart failure，and the curative effect is better than routine anti-heart failure treatment，which is worthy of clinical application.
