Will carotid artery disease kill me if i don't get treatment?

Stroke: Stroke is the most common complication of carotid artery disease. Some strokes are not survivable. If you have carotid disease, there is a higher chance of coronary disease as well. Coronary disease often leads to heart attacks and sudden death.

No : If you have carotid stenosis that is of significance then you should have surgery to remove the blockage. The degree of stenosis that makes you a candidate for surgery varies for symptomatic patients as opposed to symptomatic patients. The goal however is to prevent stoke.

Stroke: Blockage in the carotid artery can cause stroke especially if the stenosis is more than fifty percent.
