Most of the damage occurs when plaques become fragile and rupture. Plaques that rupture cause the formation of blood clots that can block blood flow or break off and travel to another part of the body. In either of these cases, if a clot blocks a blood vessel that feeds the heart, it causes a heart attack. If it blocks a blood vessel that feeds the brain, it causes a stroke.
In fact, vulnerable plaque may be buried inside the artery wall and may not always bulge out and block the blood flow through the artery. This is why researchers began to look at how inflammation affects the arteries, and if inflammation could lead to a heart attack.
