Objective: To systematically review the safety and efficacy of Qishen Yiqi Dripping Pill (QYDP) as a complementary treatment for chronic heart failure (CHF) patients.
Methods: CNKI, VIP, Wanfang Data, PubMed and Cochrane Library were retrieved for papers on randomized control trials of treating CHF patients by routine western medical treatment plus QYDP. The quality of inclusive literatures was assessed by methods from Cochrane Handbook. Valid data were extracted and analyzed by Meta-analysis using RevMan 5.1.0 Software.
Results: Totally 17 trials and 1840 patients in line with standard were included. Results of Meta-analysis showed, compared with the routine Western medical treatment group, additional use of QYDP could decrease re-admission rate [RR = 0.52, 95% CI (0.33, 0.81), P = 0.004] and the mortality rate, improve the clinical efficacy [RR = 1.18, 95% CI (1.12, 1.25), P < 0.01] and cardiac function [RR = 1.18, 95% CI (1.10, 1.27),P < 0.01], increase left ventricular ejection fraction (LVEF) [WMD = 5.57, 95% CI (4.16, 6.97), P < 0.01] of CHF patients. Subgroup analysis of LVEF showed that additional use of QYDP could further improve LVEF [ WMD = 8.34, 95% CI (6.23, 10.45), P < 0.01] of CHF patients and increase the distance of their 6-min walk test [WMD = 94.39, 95% CI (71.89, 116.89), P < 0.01]. But there was no statistical difference in plasma brain natriuretic peptide (BNP) between the two groups. No obvious adverse reaction and liver or kidney damage was reported during the trial.
Conclusions: Compared with the Western medical treatment, additional use of QYDP was safe and could further improve clinical efficacy. However, larger and high-quality clinical trials are necessary for further evidence.
