With spring break shorts and swimsuit season coming up, many people will soon show off their legs for the first time in months, and for some, that also means deciding what to do about unsightly varicose veins. The bulging purple or blue lines may be simply a cosmetic issue, or they could be a sign of a serious medical problem, says Mayo Clinic vascular surgeon Peter Gloviczki, M.D..

In the United States alone, approximately 6 million people suffer from an irregular heartbeat called atrial fibrillation (AF), and since the incidence increases with age, it is predicted that 15.9 million Americans will be affected by 2050. The most devastating side effect of AF is stroke, but a new device from Boston Scientific may prevent them from occurring.
