Abstract:

Background: Numerous prospective randomized clinical trials demonstrated favorable effect of beta-blockers in adults with chronic heart failure. However, effectiveness of beta blockers in pediatric patients with systemic ventricle systolic dysfunction was not recognized sufficiently. Limited number of pediatric patients might be the course of unrecognized carvediolol treatment benefit. Currently, no meta-analysis has examined the impact of carvedilol and conventional therapy on the clinical outcome in children with chronic heart failure due to impaired systemic ventricle systolic function.

Materials and Methods: We have systematically searched the Medline/PubMed and Cochrane Library for the controlled clinical trials that examine carvedilol and standard treatment efficacy in pediatric patients with systemic ventricle systolic dysfunction. Mean differences for continuous variables, odds ratios for dichotomous outcomes, heterogeneity between studies and publication bias were calculated using Cochrane Review Manager (Rev Man 5.2).

Results: Total of 8 prospective/observational studies met established criteria. Odds ratio for chronic heart failure related mortality/heart transplantation secondary to carvedilol was 0.52 (95% CI: 0.28-0.97, I2 = 0%). Our analysis showed that carvedilol could prevent 1 death/ heart transplantation by treating 14 pediatric patients with impaired systemic ventricle systolic function.

Conclusion: Meta-analysis demonstrated clinical outcome benefit of carvedilol in children with chronic heart failure.

Keywords: Carvedilol, childhood, systemic ventricle systolic dysfunction, heart failure.
