Q. I've been taking the blood thinner warfarin (Coumadin) for a few years. I know there are new kinds of blood thinners, but I've heard they have downsides. Should I stick with warfarin?
A. Here's what you need to know. Some medical conditions lead to blood clots. The most common one is the irregular heart rhythm called atrial fibrillation. About 20% of all strokes are caused by clots that result from atrial fibrillation — usually because of inadequate treatment with blood thinners.
