5. “Should everyone who has A-Fib be on a blood thinner like warfarin (Coumadin)?”
Not necessarily. The biggest danger of A-Fib is the increased risk of stroke, because your heart isn’t pumping out properly.
A blood thinner is used to help protect you from stroke. Your doctor will evaluate your risk of an A-Fib related stroke. If you are young, athletic and in overall good health, your doctor may rate your risk of stroke as low and not put you on a blood thinner.
