A stroke occurs when a blood clot gets clogged in the brain. If you have AFib, then it’s very easy for your body to form blood clots in your veins and arteries. I can’t say that you will have a stroke due to your AFib, but remember that every AFib patient is at an average high risk of having it.
The risk rises if your AFib is untreated or uncontrolled. So you have to do two things at the same time – treating your AFib and preventing the stroke. Your doctor may put you on an anticoagulant, such as warfarin (Coumadin) to prevent the formation of blood clots or preventing them from getting bigger. It is significant for you to take care of your heart. Do not overburden it, or it will protest with a stroke.
