Most this is caused by a blood clot that blocks a coronary artery, blood vessels that carry blood and oxygen to the heart muscle. When blood cannot reach a part of his heart, which starves the oxygen zone. If the blockage continues long enough, cells in the affected area die.Coronary artery disease is the most common cause of this condition. Coronary artery disease is the hardening and narrowing of the coronary arteries caused by the buildup of plaque inside the artery walls. Over time, plaque buildup can
- Strengthen the arteries so that less blood flows to the heart muscle,
- Lock completely arteries and blood flow, or
- Blood clots that cause the formation and block the arteries.
Attacks can also occur due to problems with very small, microscopic blood vessels of the heart. This condition is called micro vascular disease. Believed to be more common in women than in men.A less common cause of this is a severe spasm or narrowing of the coronary artery that cuts off blood flow to the heart. These spasms can occur in people with or without coronary artery disease. Artery spasm can sometimes be caused by emotional stress, exposure to extreme cold, smoking, or taking certain drugs like cocaine.There are certain factors make you more likely to develop coronary heart disease and have an attack.
