Outcome predictors and adjusted hazard ratios (HRs) for cardiovascular morbidity in asymptomatic mitral valve prolapse†
| Outcome predictors | Cardiovascular morbidity HRs (95% CI) |
|---|---|
| †HRs adjusted for age, sex, and comorbid conditions. | |
| Age ≥50 y | 3.1 (2.0 to 5.0) |
| Left atrium ≥40 mm | 2.7 (1.9 to 3.8) |
| Slight mitral regurgitation | 3.6 (2.0 to 7.0) |
| Moderate to severe mitral regurgitation | 9.1 (4.9 to 18.3) |
| Flail leaflet | 2.6 (1.5 to 4.6) |
| Baseline atrial fibrillation | 2.0 (1.2 to 3.0) |
