WINSTON-SALEM, N.C., – Nov. 4, 2013 – Doctors have known for years that atrial fibrillation (AF), or irregular heartbeat, increases the risk for stroke, but now researchers at Wake Forest Baptist Medical Center have shown that it also increases the risk for heart attack. In fact, for women and African Americans, it more than doubles the risk.
The study is published in the Nov. 4 issue of JAMA Internal Medicine.
