ABSTRACT
Objective:To discuss the effect of Qili Qiangxin capsules on cardiac function, myocardial fibrosis and ventricular remodeling of patients with dilated cardiomyopathy (DCM) and Yang Qi deficiency and blood stasis syndrome. Method:One hundred and seven patients were randomly divided into control group (53 cases) and observation group (54 cases) by random number table. Patients in control group got metoprolol succinate sustained-release tablet, 47.5 mg/time, 1 time/day, sacubitril valsartan sodium tablets, 50 mg/time, 1 time/day, hydrochlorothiazide tablets, 20 mg/time, 1 time/day, and spironolactone tablets, 20 mg/time, 1 time/day. In addition to the therapy of control group, patients in observation group were also given Qili Qiangxin capsules, 4 granules/time, 3 times/days. A course of treatment was 6 months. Before and after treatment, levels of left ventricular end-diastolic diameter (LVEDd), left ventricular ejection fraction (LVEF), left ventricular end systolic diameter (LVESD), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular myocardial mass (LVM) and left ventricular myocardial mass index (LVMI) were recorded by echocardiography. The classification of cardiac function was recorded by New York College of Cardiology (NYHA). Lee's heart failure and Yang Qi deficiency and blood stasis syndrome were scored. And levels of N-terminal B-type natriuretic peptide (NT-proBNP), soluble ST2 (sST2), galectin-3 (galectin-3), angiotensin-Ⅱ(Ang-Ⅱ), matrix metalloproteinase-2 (MMP-2), MMP-9, matrix metalloproteinase inhibitor-1 (TIMP-1), type I procollagen carboxy-terminal peptide (PIP) and type I collagen carboxy-terminal cross-linking peptide (CITP) were detected. Result:After treatment, levels of LVEDd, LVESD, IVST, LVPWT, LVM and LVMI were lower than those in control group (PPZ=2.031, PPPConclusion:In addition to the routine western medicine, Qili Qiangxin capsules can relieve clinical symptoms, degree of heart failure of DCM patients and ventricular remodeling, ameliorate heart function, regulate levels of sST2, galectin-3, MMPs and Ang-Ⅱ, inhibit myocardial fibrosis, and delay heart failure.
