What is carotid artery stenosis and stroke?

Blocked plumbing: Your carotid arteries deliver blood to your brain and head. Carotid artery stenosis is when gunk and inflammation make it harder for the blood to flow. When your brain doesn't get enough blood, parts of your brain can die. That's a stroke. The good news? You can prevent this by: eating right, moving 30-60 minutes every day, controlling your blood pressure, not smoking. Thanks for asking.

2 things: Carotid artery stenosis means narrowing of the artery. Stroke is death or damage to brain due to circulatory issues. Many strokes (approx 1/3rd) are due to carotid artery disease. Although frequently connected, they are not the same. Many strokes occur without carotid stenosis. Many carotids are completely occluded (slowly) without resultant strokes.

See below: Carotid artery disease means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk in the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the risk of stroke.
