The aim of this study was to look at the association between new onset atrial fibrillation (AF) and mortality as well as the influence of cardiovascular co-morbidities on risk in middle-aged women without cardiovascular disease at baseline. This large study demonstrated that those women who developed AF had an increased risk of all-cause, cardiovascular, and non-cardiovascular mortality compared with women who did not develop AF. Excess mortality associated with AF appears attributable to the occurrence of nonfatal cardiovascular events prior to death. It would seem that cardiovascular risk factors should be managed aggressively in patients with AF to try to reduce these deaths. Conen D, et al.
