title: The effect of trimetazidine added to pharmacological treatment on all-cause mortality in patients with systolic heart failure.
abstract: The anti-ischemic agent trimetazidine (TMZ) added to pharmacological treatment appears to have positive effects on cardiac parameters of patients with heart failure (HF) as a result of specific antioxidant properties.
  
  
  OBJECTIVE
  We aimed to verify whether the marked improvement provided by TMZ in echocardiographic and clinical parameters was likely to translate into reduced all-cause mortality in systolic HF patients.
  
  
  METHODS
  Meta-analysis of available published prospective randomized controlled trial (RCT) data (1967-2014) retrieved from PubMed, Web of Science and Cochrane Collaboration.
  
  
  RESULTS
  A total of 326 patients from 3 RCTs were analyzed: 164 who received TMZ on top of pharmacological HF therapy and 162 controls. Study durations ranged from 12 to 48 months. The analysis had no publication bias and the studies were homogeneous (p = 0.442, I(2) = 0). The results show a significant effect of TMZ on the reduction of all-cause mortality (RR = 0.283, p < 0.0001). The rate of events attributable to the drug was lower with TMZ than it was among control patients.
  
  
  CONCLUSIONS
  This meta-analysis suggests that in patients with HF, TMZ given as an add-on therapy is likely to provide a protective effect, reduce all-cause mortality and increase event-free survival, and could be an effective and useful adjunct to our armamentarium for the treatment of HF patients.
