What Is A Heart Attack & And It's Risk Factors? Dr. Amy Epps: A heart attack is a process in the coronary artery that is usually caused by long term damage to the coronary artery based on your risk factors. Risk Factors Dr. Amy Epps: High blood pressure called hypertension, high cholesterol, if you're diabetic, if you're a smoker. All of those processes can damage the coronary arteries. These are the arteries to the heart muscle and some sort of trigger whether it's a stress or a plaque rupture inside the coronary artery, causes it to shut down or block, and that will lead to heart attack. The reason why is that, that artery supplies a certain portion of the heart muscle. So if that artery is blocked by a plaque, usually it's a plaque which is a form of cholesterol that breaks off and clogs the artery. That portion of the heart muscle will not give blood flow to it, and that portion will die or start to die of the muscle, start to die, and that's what a heart attack is.
