Question

What happens to heart while heart attack?

Answer 1

Heart attack:

1. A heart attack occurs when the flow of blood to the heart is blocked.
2. The blockage is mostly due to buildup of fat, cholesterol and other substances which form a plaque in the arteries that feed the heart which stops the blood from moving normally.
3. The plaque eventually breaks away and forms a clot.
   
4. The interrupted blood flow can damage heart muscle.
5. Heart attack is also called a myocardial infarction which can be fatal.
