When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years.
Eventually, an area of plaque can rupture (break open) inside of an artery. This causes a blood clot to form on the plaque's surface. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.
If the blockage isn't treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.
heart disease or heart attack
Heart attacks are causes by having blockages in the arteries that surround the heart. This causes a lack of blood flow which in turn damages muscle. And is true so.......
Obstuction of blood flow to the heart resulting in damage/death of heart muscle tissue.
The progression of atherosclerosis leads to heart attack when the artery wall thickens as a result of the accumulation of white blood cells.
Chest pain after a heart attack or during a heart attck is caused by constriction of the blood vessels. Your heart needs blood to survive and when the vessels constrict, it limits bloodflow to your heart. This causes intense pain--that is why you are given nitroglycerin tablets. Nitro opens the vessels.
How about cocaine. It causes vaso-constriction of blood vessels in your body including vessels in your heart, which can result in a heart attack.
the stop of blood flow to the heart
heart mediater, it causes rapid increase in heart rate, causes stroke, heart attack etc.
Cardiogenic shock causes the nausea.
A blocked (occluded) coronary artery is what causes a heart attack.

The medical term for heart attack is myocardial infarction. This is when for one reason or another the heart fails to pump normal and eventually stops. A heart attack usually occurs when someone has heart disease, has a heart block or some other contributing factors such as high cholesterol, poor diet, or smoking. These all contribute to causing heart blockages which are the most common causes of a heart attack.
