So why the fuss & preamble? In another analysis of the Women's Health Initiative published this week in JAMA , after following 34,722 predominantly Caucasian women, average age 53 years old, all free of AF & cardiovascular disease at baseline for median of 15+ years, the authors concluded that new onset AF was associated with an increase risk of all-cause mortality, cardiovascular mortality & non-cardiovascular mortality, at least double that of those without AF.
While the overall risk of developing AF is low, the fact remains that upon diagnosis, one's mortality increases substantially. While this study makes no conclusions as to cause & effect and while there is no proof of any ability to modify mortality once AF is diagnosed, there is no reason not to aggressively prevent stroke & cardiovascular events from occurring.
