a man who doesn't stand still. but jim has afib, atrial fibrillation, an irregular heartbeat not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto jim's on the move. jim's doctor recommended xarelto. like warfarin, xarelto is proven effective to reduce afib-related stroke risk. but xarelto is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem that doesn't require routine blood monitoring. so jim's not tied to that monitoring routine.
