Heart attack 

It can occur when the flow of blood to the heart is blocked. The blockage of the blood due to cholesterol, fat, and other substances form a plaque in the arteries and feed the heart. In some cases, a plaque can rupture that forms a clot and blocks the flow of blood to the heart. Due to the interruption of blood flow, it can damage the heart muscle.

A heart attack can occur when one or more of your coronary arteries becomes blocked. Sometimes, a buildup of fatty deposits such as cholesterol forms substances known as plaques that can narrow the arteries. This type of condition is called coronary artery disease that causes heart attacks.

A plaque can spill and rupture cholesterol and other substances into the bloodstream during a heart attack. A blood clot forms at the site of the rupture and if the clot is large, it can shut down the flow of blood via the coronary artery. After that, it starving the heart of oxygen and nutrients (ischemia).

There is another cause of heart attack is a spasm of the coronary artery, which blocks the flow of blood to a part of the heart muscle. Tobacco and illicit drugs including cocaine can cause a life-threatening spasm in human beings. Now coronavirus may also harm the heart that results in a heart attack in any individual.
