Text: After multivariate analysis, atrial fibrillation remained significantly associated with all-cause mortality (relative risk [RR] 1. 34, 95 % confidence interval [CI] 1. 12 to 1. 62, p = 0. 002), progressive pump-failure death (RR 1. 42, 95 % CI 1. 09 to 1. 85, p = 0. 01), the composite end point of death or hospitalization for heart failure (RR 1. 26, 95 % CI 1. 03 to 1. 42, p = 0. 02), but not arrhythmic death (RR 1. 13 ; 95 % CI 0. 75 to 1. 71 ; p = 0. 55).
