Outcome predictors and adjusted hazard ratios (HRs) for total and cardiovascular (CV) mortality in asymptomatic mitral valve prolapse*
| Outcome predictors | Total mortality HRs (95% CI) | CV mortality HRs (CI) |
|---|---|---|
| *HRs adjusted for age, sex, and comorbid conditions. | ||
| Moderate to severe mitral regurgitation | 1.8 (1.03 to 3.0) | 3.0 (1.5 to 5.8) |
| Ejection fraction <50% | 2.3 (1.05 to 4.4) | 3.8 (1.6 to 8.1) |
