Heart attack
A heart attack happen when blood flow to the heart is totally blocked. Obstruction is most often the formation of fat, cholesterol and other substances, which form a plaque in the arteries feeding the heart (coronary arteries).
The plaque breaks off final and forms a clot. Interrupted blood flow can damage or destroy part of the motor of the heart.
Heart attack, also known as myocardial infarction, can be fatal, but the treatment has gaming improved markedly over the years. If you think you may have a heart attack, it is important to call 911 or emergency medical support.
