What happens during an embolic stroke?
What is an embolic stroke? An embolic stroke occurs when a blood clot that forms elsewhere in the body breaks loose and travels to the brain via the bloodstream. When the clot lodges in an artery and blocks the flow of blood, this causes a stroke. This is a type of ischemic stroke.
What is difference between thrombotic and embolic stroke?
Thrombotic strokes are caused by a blood clot (thrombus) in an artery going to the brain. Embolic strokes occur when a clot that’s formed elsewhere (usually in the heart or neck arteries) travels in the blood stream and clogs a blood vessel in or leading to the brain.
How is embolic stroke diagnosed?
Because treatment depends on the type of stroke, your doctor may use head CT or head MRI to help diagnose your condition. Other tests may include blood tests, electrocardiogram (ECG or EKG), carotid ultrasound, echocardiography or cerebral angiography.
Is an embolic stroke a mini stroke?
Embolic stroke About 15% of embolic strokes occur in people with atrial fibrillation, a type of abnormal heart rhythm in which the upper chambers of the heart do not beat effectively.

Where do embolic strokes come from?
Embolic stroke Embolic strokes are usually caused by a blood clot that forms elsewhere in the body (embolus) and travels through the bloodstream to the brain. Embolic strokes often result from heart disease or heart surgery and occur rapidly and without any warning signs.
Is a TIA and embolic stroke?
A transient ischemic attack (TIA), or “mini stroke,” usually happens before a thrombotic stroke. Embolic stroke is caused by a clot that travels from somewhere else in the body, usually the heart. The clot then blocks an artery leading to or in the brain.
What causes embolic strokes?
Embolic strokes are usually caused by a blood clot that forms elsewhere in the body (embolus) and travels through the bloodstream to the brain. Embolic strokes often result from heart disease or heart surgery and occur rapidly and without any warning signs.
Is CVA a cardiovascular disease?
Support innovative, timely and high impact research to better understand basic, translational or clinical sciences of disorders of the heart, blood vessels, and cardiac and brain vasculature, collectively called cardiovascular disease (CVD) and cerebrovascular accident (CVA) or stroke.
