Coronary Revascularization for Heart Failure with Coronary Artery Disease: A Systematic Review and Meta-Analysis of Randomized Trials
Pooled result · All-cause mortalityResult — go to the resultHazard ratio 0.88 95% CI 0.79–0.99Authors' conclusion
For patients with chronic HF and CAD enrolled in RCTs, the effect of coronary revascularization on all-cause mortality was statistically significant but neither substantial (HR 0.88) nor robust (upper 95% CI close to 1.0).
Study context
- Population
- Chronic heart failure (HF) due to coronary artery disease (CAD) (most aged <65 years; 85% men; 67% with LVEF ≤35%)
- Participants
- 2,842 participants5 randomized controlled trials (RCTs)
- Comparison
- Coronary revascularization vs medical therapy alone
- Outcome
- All-cause mortality
Methodological detailsRCTs were not blinded
- RCTs were not blinded
