OBJECTIVE  To explore the clinical efficacy of Fuxin Mixture in the treatment of patients with heart failure of yang deficiency and water inundation type after myocardial infarction and its effect on serum myocardial injury and ventricular remodeling related indicators.

  METHODS  A total of 92 patients with heart failure of yang deficiency and water inundation type after myocardial infarction were randomly divided into an observation group and a control group (n=46). The control group was given basic western medicine treatment, and the observation group was given Fuxin Mixture on the basis of the control group's treatment. The TCM syndrome scores, ultrasound cardiogram indices left ventricular ejection fraction (LVEF), left ventricular Tei index, and stroke volume (SV), serum myocardial injury indices serum N-terminal pro-B-type natriuretic peptide (NT-ProBNP) level, serum high-sensitivity cardiac troponin Ⅰ (hs-cTnI) level, and creatine kinase isoenzyme (CK-MB) level, serum ventricular remodeling indices hypoxia-inducible factor 1α (HIF-1α), soluble growth-stimulated gene expressed 2 protein (sST2), and angiotensin Ⅱ (AngⅡ), and changes in the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were evaluated before and after treatment. The two groups were followed up for 1 year after treatment to observe the occurrence of major adverse cardiovascular events.

  RESULTS  After treatment, the TCM syndrome scores of both groups were significantly reduced (P < 0.01), the observation group was better than the control group (P < 0.05, P < 0.01), and the total effective rate of TCM in the observation group was better than that of the control group (P < 0.05); the serum ultrasound cardiogram indexes, myocardial injury, ventricular remodeling indexes and MLHFQ scores of the two groups were significantly reduced (P < 0.01), and the observation group was better than the control group (P < 0.01). During the follow-up period, the all-cause mortality, malignant arrhythmia rate and acute heart failure rate of the observation group after treatment were significantly lower than those of the control group (P < 0.05, P < 0.01).

  CONCLUSION  Fuxin Mixture has significant clinical efficacy in the treatment of patients with heart failure of yang deficiency and water inundation type after myocardial infarction, and the efficacy mechanism may be related to its reduction of myocardial injury and inhibition of ventricular remodeling.
