Heart attack also known as Myocardial infarction is an injury or damage to the heart muscles. Myo is Latin for muscles, while cardial refers to anything that relates to the heart, while infarction means the death of tissues due to inadequate supply of blood.
A heart attack normally occurs when the flow of blood to the heart is obstructed mostly by buildup of cholesterol, fat, and other substances, which accumulates and forms a blockade in the coronary artery that supplies blood to the heart. The obstructed blood flow in turn destroys the heart muscle. A heart attack can be fatal.
The heart is a very delicate organ in the body and requires to be at its optimum at all times. The heart muscle needs a constant supply of oxygen filled blood to feed it. The coronary artery is responsible for transporting blood to the heart, so if you get coronary artery disease, the artery becomes too narrow and limits the flow of blood through it.
Calcium, protein, inflammatory cells and fatty matters accumulates within the artery to form plaques. Those plaques are hard on the outside and squishy on the inside. When the plaque gets hard the outer covering breaks down, this is called plaque rupture, then platelets move to that area of the artery, forming a blood clot around the plaque. If the blood clot totally blocks the artery the heart becomes oxygen malnourished.
Within a short time the weakening and death of the heart muscle occurs. This is when heart attack begins. The amount of damage is determined by the size of the region the blocked coronary artery supplies blood to and the amount of time between injury and treatment.
Another cause of heart attack, although rare is the spasm of the coronary artery. During a coronary spasm the coronary artery contracts on and off limiting the flow of oxygen rich blood to the heart muscle, it is also called ischemia. It may happen to people without a notable coronary artery disease.
