Does new-onset atrial fibrillation increase the risk of mortality in initially healthy women?
In initially healthy women, developing new-onset atrial fibrillation is independently associated with increased all-cause, cardiovascular, and noncardiovascular mortality.
Among a group of healthy women, new-onset AF was independently associated with all-cause, cardiovascular, and noncardiovascular mortality, with some of the risk potentially explained by nonfatal cardiovascular events.
David Conen (2011) studied this question.
