Heart attack
Plaques inside the coronary arteries sometimes break open or "rupture. " пїЅ This is what causes most heart attacks. When a plaque breaks open, it causes a blood clot to form inside the artery. As the clot grows, it can completely block off the flow of blood through the artery. That means that the tissue on the other end of the clogged artery does not get the blood and oxygen it needs, so it gets damaged or dies.

Coronary artery bypass graft surgery
During coronary artery bypass surgery, the surgeon removes a piece of blood vessel from the leg, chest, arm, or belly. Then the surgeon uses that piece of blood vessel (called a "graft") to reroute blood around the blocked artery. The surgery is called "bypass surgery" because it bypasses the blockage. Some people have more than one blocked artery bypassed. In this picture, the graft came from a vein in the leg called the "saphenous vein. " пїЅ But grafts can come from other places, too.
