Myocardial Infarction/Heart Attack
A heart attack occurs when the blood vessels (coronary arteries) supplying the heart suddenly become completely blocked. The abrupt interruption of blood and oxygen to the heart can cause the heart muscle to die. Fatty deposits called plaque usually cause the sudden interruption. These deposits can build up on the inside of the coronary arteries and rupture without warning causing a blood clot to form in the artery. When a coronary artery becomes completely blocked, an area of the heart muscle will die causing a myocardial infarction.
It is important to know the signs and symptoms of a heart attack and seek immediate care.
