i'm brian vickers, nascar® driver. i'm kevin nealon comedian. and i'm arnold palmer, professional golfer. know what we have in common? we talked to our doctors about treatment with xarelto®. me, when i had a blood clot in my leg that could have traveled to my lungs. that's why i took xarelto®, too. xarelto® is proven to treat and help reduce the risk of dvt and pe blood clots. i took xarelto® for afib... an irregular heartbeat that can lead to a stroke from a blood clot. xarelto® is proven to reduce the risk of stroke in people with afib, not caused by a heart valve problem. hey, well i'm glad we got together. for people with afib currently well managed on warfarin there is limited information on how xarelto® and warfarin compare in reducing the risk of stroke. i tried warfarin before, but the blood testing routine and dietary restrictions had me off my game. tell me about it. let's see, golf clinic, or blood clinic? ooh, that's a tough one.
