Combination of heart failure and atrial fibrillation worsens ethnicity-related disparity: an individual patient-level meta-analysis of randomized trials
- Individual patient-level meta-analysis of randomised trials
- placebo-controlled trials
- confounder-adjusted
- propensity-score matching
Authors' conclusion
Non-white patients with HF and reduced ejection fraction suffer from substantially higher rates of death than white patients, with comorbid atrial fibrillation leading to significant worsening of this ethnicity-related disparity.
Study context
- Population
- Patients with heart failure (HF) (reduced EF) in 12 placebo-controlled RCTs (11 vs beta-blockers, 1 vs spironolactone); 3145 with comorbid atrial fibrillation (AF), 13,568 in sinus rhythm
- Participants
- 16,713 patients · 12 RCTs
- Comparison
- Non-white vs white ethnicity
- Non-whiten = 1,899
- Outcome
- All-cause mortality
- Follow-up
- Median 1.4 years
