- The effect of coenzyme Q10 on morbidity and mortality in chronic heart failure (Q-SYMBIO trial)
2-year double-blind multi-center RCT (n=420) in chronic heart failure found 300mg/day CoQ10 (ubiquinone) reduced cardiovascular mortality by 43% and major adverse cardiac events by 50% vs placebo.
- Coenzyme Q10 for heart failure (Cochrane Review)Madmani ME, Yusuf Solaiman A, Tamr Agha K, et al. · 2014 · Cochrane Database of Systematic ReviewsMeta-analysis
Cochrane review of 7 RCTs noted evidence suggests CoQ10 may improve ejection fraction and reduce hospitalization in heart failure, but called for larger long-term trials — Q-SYMBIO partially answered this call.
