Coronary artery spasm is a temporary, sudden narrowing of one of the coronary arteries (the arteries that supply blood to the heart). The spasm slows or stops blood flow through the artery and starves part of the heart of oxygen-rich blood.

Coronary Artery Spasm
A less common cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off blood flow through the artery. Spasms can occur in coronary arteries that aren't affected by atherosclerosis.

Coronary artery spasm
Angina is a specific type of pain in the chest caused by inadequate blood flow through the blood vessels (coronary vessels) of the heart muscle (myocardium).
coronary artery spasm - a sudden closing of an artery, which cuts off blood flow to the heart and causes symptom of angina or heart attack.

If your chest pain is due to coronary artery spasms, you may be prescribed drugs to control your discomfort. These include nitrates, such as nitroglycerin, which work by increasing blood flow to the heart.
Variant (Prinzmetal’s angina) - caused by coronary artery spasm - usually occurs at rest and not on exertion.

The primary cause is atherosclerosis, although platelet aggregation, coronary artery spasm, non-vascular mechanisms such as hypoglycemia, and increased metabolic need (as in hyperthyroidism) can also be important.
Angina, variant: Chest pain due to coronary artery spasm, a sudden constriction of a coronary artery (one of the vessels that supply the heart muscle with blood rich in oxygen) depriving the heart muscle of blood and oxygen.
Coronary artery spasm: Muscles in the wall of the coronary artery can go into spasm. This narrows the artery and causes blood to slow or stop flowing through it. When the spasm stops, the artery and blood flow return to normal.
In rare cases, the coronary artery spasms and contracts, obstructing blood flow and causing chest pain. If severe, the spasm can completely block blood flow and cause a heart attack.
Two of the primary causes of heart attack in a seemingly healthy heart are blood clots and coronary artery spasms. Both can lead to a blockage of blood flow to the heart.

Another, less common cause of a heart attack is a coronary artery spasm. This can occur as a result of drug use (such as cocaine,) and suddenly shuts down the blood flow from one of the arteries to the heart.

Drug history should note use of drugs that can trigger coronary artery spasm (eg, cocaine, triptans, phosphodiesterase inhibitors) or GI disease (particularly alcohol, NSAIDs).
This type is primarily due to sudden coronary artery spasm, though atherosclerosis may also be a component. The third, most severe type is called unstable angina. This angina occurs with no predictability and can quickly lead to a heart attack.
Variant Angina - This is a type of angina that is very rare and occurs without warning: what happens is that a coronary artery spasms and it can lead to abnormal heart rhythms.
Variant angina pectoris, or Prinzmetal's angina, however, can occur when a person is at rest. It occurs as a result of coronary artery spasm and may occur frequently for six months or more.
A third, a rare type of angina called variant angina (also called Prinzmetal's angina) is caused by a coronary artery spasm.
