Background: Despite advancements in chronic heart failure (CHF) treatment, the effect often remains unsatisfactory and unstable. More effective therapies are needed. Qishen granules (QSG) are a novel Chinese botanical drug effective in treating CHF in animal models, but clinical evidence remains inadequate.Objective: This study aims to evaluate the effects of QSG on patients with CHF.Methods: We enrolled CHF patients in this 12-week, randomized, double-blind, placebo-controlled trial and randomly assigned them to the QSG (twice a day, 6.8 g granules at once) or placebo group. The primary endpoint was a change in the plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level after treatment. The secondary outcome consists of the New York Heart Association (NYHA) functional classification, 6-min walking distance (6MWD), TCM syndrome integral scale, quality of life, and echocardiographic index.Results: A total of 191 patients completed the 12-week follow-up period, with 94 in the QSG group and 97 in the placebo group. The Qishen granules group demonstrated a considerably greater reduction in NT-proBNP than the placebo group (50% vs 32% for QSG vs placebo, respectively; p = 0.011). Patients who received QSG performed better in the NYHA functional rank, 6MWD, TCM syndrome integral scale, and quality of life (p < 0.05). The QSG group performed better in HFrEF patients regarding the efficiency of NT-proBNP. There was no statistical significance in the change in evaluated safety parameters, such as blood routine and biochemistry.Conclusion: Based on standard treatment, Qishen granules further reduced the levels of NT-proBNP when compared with placebo. Together with other outcomes, our findings suggest that QSG could be used in combination therapy for CHF.Clinical Trial Registration: www.clinicaltrials.gov, identifier NCT03027375.

BackgroundEvidence of the preventive and therapeutic effects of enalapril on cardiotoxicity caused by chemotherapy needs to be further confirmed and updated.MethodsWe performed a systematic review of studies from electronic databases that were searched from inception to January 29, 2019, and included relevant studies analyzing enalapril as a cardioprotective agent before or during the use of anthracyclines by oncology patients. Homogeneous results from different studies were pooled using RevMan 5.3 software. The Cochrane risk-of-bias tool was used to determine the quality of the studies.ResultsWe examined and screened 626 studies according to specific criteria and ultimately included seven studies that were relevant to the indicated topic. Among them, three studies reported the incidence of death during 6- and 12-month follow-up periods. Six of the seven included studies showed possible positive results, suggesting that enalapril plays a cardioprotective role, while five of these studies showed that there was a significant difference in the left ventricular ejection fraction (LVEF) between an enalapril group and a control group (weighted mean difference (WMD) = 7.18, 95% CI: 2.49–11.87, I2 = 96%, P < .001). Moreover, enalapril was beneficial in reducing troponin I (TnI), creatine kinase myocardial band (CK-MB) and N-terminal pro-b-type natriuretic peptide (NT-proBNP) levels in cancer patients treated with anthracycline.ConclusionsAlthough a protective effect of enalapril on myocardial toxicity was observed in terms of the LVEF values and TnI, CK-MB and NT-proBNP levels, its use in the prevention and treatment of cardiotoxicity caused by anthracycline needs to be investigated by more scientific research.

Chronic heart failure (CHF) is a major public health problem in huge population worldwide. The detailed understanding of CHF mechanism is still limited. Zheng (syndrome) is the criterion of diagnosis and therapeutic in Traditional Chinese Medicine (TCM). Syndrome prediction may be a better approach for understanding of CHF mechanism basis and its treatment. The authors studied disturbed metabolic biomarkers to construct a predicting mode to assess the diagnostic value of different syndrome of CHF and explore the Chinese herbal medicine (CHM) efficacy on CHF patients. A cohort of 110 patients from 11 independent centers was studied and all patients were divided into 3 groups according to TCM syndrome differentiation: group of Qi deficiency syndrome, group of Qi deficiency and Blood stasis syndrome, and group of Qi deficiency and Blood stasis and Water retention syndrome. Plasma metabolomic profiles were determined by UPLC-TOF/MS and analyzed by multivariate statistics. About 6 representative metabolites were highly possible to be associated with CHF, 4, 7, and 5 metabolites with Qi deficiency syndrome, Qi deficiency and Blood stasis syndrome, and Qi deficiency and Blood stasis and Water retention syndrome (VIP > 1, p < 0.05). The diagnostic model was further constructed based on the metabolites to diagnose other CHF patients with satisfying sensitivity and specificity (sensitivity and specificity are 97.1 and 80.6% for CHF group vs. NH group; 97.1 and 80.0% for QD group vs. NH group; 97.1 and 79.5% for QB group vs. NH group; 97.1 and 88.9% for QBW group vs. NH group), validating the robustness of plasma metabolic profiling to diagnostic strategy. By comparison of the metabolic profiles, 9 biomarkers, 2-arachidonoylglycerophosphocholine, LysoPE 16:0, PS 21:0, LysoPE 20:4, LysoPE 18:0, linoleic acid, LysoPE 18:2, 4-hydroxybenzenesulfonic acid, and LysoPE 22:6, may be especially for the effect of CHM granules. A predicting model was attempted to construct and predict patient based on the related symptoms of CHF and the potential biomarkers regulated by CHM were explored.This trial was registered with NCT01939236 (https://clinicaltrials.gov/).
