Heart attack occurs because of damage of heart muscle. Muscles of the heart is damaged when it does not receive enough oxygen. Nourishment of heart for oxygen is supplied through blood.
This is similar to nourishment of other tissues in the body. A special type of blood vessels are responsible for the supply of oxygen to heart.
These blood vessels are known as coronary vessels. During heart attacks, flow of blood is stopped in these coronary vessels.
This is because of a clot in the coronary vessels. Therefore, the heart muscle is damaged. Which in turn leads to heart attack.
