Is It AFib That Causes Strokes?

There are several causes of stroke, including high blood pressure and smoking, and atria fibrillation is one of them. Nobody can say that atria fibrillation must lead to strokes, but it’s true that AFib patients are at average high risk of having a stroke.

When a person has atrial fibrillation, his upper chambers of the heart (atria) beat up to four times faster than the rest of the heart. Due to the ineffective contractions of the upper chambers, the blood can’t eject as it is supposed to, therefore, it pools and stagnates in the atria. As blood flows sluggishly, it gradually becomes thicker and thicker. Finally, blood clots are formed in the atria, especially in the left atrium. Any one of the blood clots can dislodge from the appendage and travel to other parts of the body. When it comes to the brain and cuts off oxygen supply to a portion of the brain, a stroke occurs on the patient.
