A heart attack or myocardial infarction occurs in areas of the heart that lack blood flow. Blood, carried by coronary arteries around the heart, would normally provide oxygen & nutrition while taking away carbon dioxide. Without oxygen, the area would become necrotic & myocardial cells would die.
Angina, or chest pain, is usually a precursor to a heart attack. Patients that experience chest pain should see their health care provider to possibly undergo a stress test. A cardiac catheterization may be needed to determine which coronary vessel(s), also called coronary arteries, is occluded or blocked. Occlusion occurs due to years of atherosclerosis, or buildup of lipids from diet & hereditary factors. If the left main coronary artery is blocked, usually a CABG (coronary artery bypass graft) is needed. If other arteries are involved, a coronary stent might be another option. If minimal occlusion is found during catheterization, a patient may just require an antiplatelet agent, such as aspirin or clopidogrel.
because you eat too much fat which builds up on the artery walls causing lesser blood flow to the heart causing heart attack or stroke. there are other causes like stress and aging arteries as well. other complex disorders cause CHD such as sleep apena (stop and start breathing while sleeping) and more.
Heart disease is a term that covers a variety of conditions that can lead to heart attack, stroke and death.
it usually starts when there is narrowing or blockage in the coronary arteries, the blood vessels that supply blood to the heart itself
smoking, drinking too much, blocked arteries, it can be passed down (hereditary), too little exercise, and taking drugs
The pain of lack of oxygen to the heart (angina) is similar in both heart attack and coronary artery disease. Heart attack is the presence of damage to the heart as a result of this lack of oxygen.
A heart attack
Blockage of the coronary artery will result in a heart attack.
No. The medical term for heart attack is myocardial infarction, or the death of heart myocardium (basically the heart muscle). Coronary Heart Disease (CAD) is a disease where plaques of cholesterol are deposited in the heart's coronary arteries (which feed the heart blood during diastole). Ruptures of these plaques can cause clots in may however result or cause myocardial infarctions, due to a sudden yet complete blockage of a coronary artery.
Coronary arteries are the vessels that provide blood supply to the heart muscle itself. If they are blocked or damaged, a heart attack may result.
When coronary circulation is prevented in humans the result is a heart attack. The function of the coronary circulation is to nourish tissues of the heart.
A blocked (occluded) coronary artery is what causes a heart attack.
The pain of lack of oxygen to the heart (angina) is similar in both heart attack and coronary artery disease. Heart attack is the presence of damage to the heart as a result of this lack of oxygen.

Coronary occlusive artery disease-- Blockage of the arteries that supply blood to the heart; frequently a precursor to a heart attack.
