To prevent clots: Some irregular heart beats can lead to clots. If you need to have blood that does not make clots easily, we give Coumadin (warfarin) because it is "defective vitamin k". Your liver tries to use the Coumadin (warfarin) to make things necessary to make clots. Since the liver is getting defective vitamin k, it makes less things to make clots. If you eat a lot of k. Or have some other cause for clots, Coumadin (warfarin) fails.

Coumadin (warfarin): this is a blood thinner, maybe he has an ongoing rhythm problem called atrial fibrillation, or he may have prosthetic heart valve.
