Objective To investigate the effect of Trimetazidine on serum inflammatory factors levels and cardiac function in patients with chronic heart failure (CHF). Methods 94 CHF patients admitted into our hospital from April 2015 to March 2016 were divided into two groups randomly, 47 cases in each. Control group took Atorvastatin, and on this basis observation group was given Trimetazidine. The serum inflammatory factors levels, brain natriuretic peptide (BNP), cardiac function and clinical efficacy of two groups after treatment for 6 months were compared. Results The serum C-reactive protein (CRP), BNP, Tumor necrosis factor-α (TNF-α) levels of observation group were lower than control group (P<0.05); The left ventricular end-systolic diameter (LVESD), Left ventricular end-diastolic diameter (LVEDd) levels of observation group significantly decreased compared with control group, but left ventricular ejection fraction (LVEF) was higher than control group (P<0.05); The curative effective rate of observation group significantly increased compared with control group (P<0.05). Conclusion Trimetazidine for treating CHF patients may effectively increase clinical efficacy, decrease serum inflammatory factors and improve cardiac function, which is worthy of clinical promotion and application.
