Qishenyiqi dripping pill improves ventricular remodeling and function in patients with chronic heart failure: A pooled analysis

BACKGROUND: Qishenyiqi dripping pill for chronic heart failure (CHF) remains controversial due to lack of high-quality trials. Therefore, we conduct this pooled-analysis to evaluate the efficacy and safety of Qishenyiqi in CHF patients. METHODS: We searched for randomized clinical trials for Qishenyiqi dripping pill in treating CHF up to August 2018 through China National Knowledge Infrastructure (CNKI), the PubMed Database, the Wanfang Database, the China Scientific Journal Database (VIP), and the Chinese Biomedicine Literature Service System. RevMan 5.3 was used for pooled analyses. Based on the New York Heart Association (NYHA) classification, the clinical therapeutic effect was collected as the primary endpoint. RESULTS: The efficacy and safety of Qishenyiqi combined with routine treatment significantly increased NYHA functional classification, left ventricular ejection fraction, cardiac index, and 6-minute walking test and decreased brain natriuretic peptide, left ventricular end-diastolic, and end-systolic dimensions with no obvious side effects in comparison with routine therapy alone. CONCLUSIONS: Together these results provide important insights into Qishenyiqi is effective and safe in improving ventricular remodeling and function of CHF patients.
