More than 12 million Americans are estimated to suffer from atrial fibrillation by 2030, according to doctors.

For patients with atrial fibrillation, the risk of stroke or heart attack from stopping anticoagulants usually outweighs the risk of bleeding, according to new findings from the University of Bath.

The complications portend a rise in the arrhythmia, and also in mortality, with an average time to event of 7 years.
