Additional Use of Trimetazidine in Patients With Chronic Heart Failure: A Meta-Analysis

Objectives m of this meta-analysis was to evaluate the effects of additional trimetazidine (TMZ) treatment on patients with chronic heart failure (CHF). ound cting results currently exist on the clinical use of TMZ in CHF patients. s , MEDLINE, EMBASE, and EBM Reviews databases were searched through November 2010 for randomized controlled trials (RCTs) assessing TMZ treatment in CHF patients. Data concerning the study design, patient characteristics, and outcomes were extracted. Risk ratio (RR) and weighted mean differences (WMD) were calculated using fixed or random effects models. s n RCTs involving 884 CHF patients were included. Hospitalization for cardiac causes (RR: 0.43, p = 0.03), but not all-cause mortality (RR: 0.47, p = 0.27), was reduced by TMZ treatment. Moreover, TMZ therapy was associated not only with the increase of left ventricular ejection fraction (WMD: 6.46%, p < 0.0001) and total exercise time (WMD: 63.75 seconds, p < 0.0001), but also with the decrease of New York Heart Association functional class (WMD: −0.57, p = 0.0003), left ventricular end-systolic diameter (WMD: −6.67 mm, p < 0.0001), left ventricular end-diastolic diameter (WMD: −6.05 mm, p < 0.0001), and B-type natriuretic peptide (WMD: −203.40 pg/ml, p = 0.0002). sions onal use of TMZ in CHF patients may decrease hospitalization for cardiac causes, improve clinical symptoms and cardiac function, and simultaneously ameliorate left ventricular remodeling.
