A heart condition that can lead to a stroke is called an atrial fibrillation (AFib). AFib is an irregular heartbeat that can cause blood to pool in the heart's upper chambers, leading to the formation of a clot that can travel to the brain and block blood flow.
When blood flow to the brain is blocked, a stroke occurs. AFib increases the risk of having a stroke five times more than someone without AFib. It is estimated that 15-20% of all strokes are associated with atrial fibrillation.
AFib is a common condition and can be caused by many factors, including high blood pressure, certain medicines, obesity, thyroid issues, and excessive alcohol consumption. It can also be caused by genetics or other heart conditions, such as heart valve disease or heart failure.
In order to reduce the risk of stroke, people with AFib should work with their healthcare provider to manage their condition. This often includes lifestyle modifications, such as quitting smoking, exercising regularly, and eating a healthy diet. It may also include taking blood thinners or anti-arrhythmic medications.
If left untreated, AFib can lead to serious consequences, including stroke. Therefore, it is important to talk to a healthcare professional if you are experiencing any signs or symptoms of AFib. By taking steps to manage your condition, you may be able to reduce your risk of having a stroke.
