What Causes Heart Attacks?

Heart attack related questions such as the causes of heart attack and the treatment of heart disease have remained astonishing to lots of people.

Causes of heart attack can be as a result of blockages in heart arteries. Usually the blockage is caused by atherosclerosis, which is the build-up of fatty deposits called plaque inside the artery. This build-up is like the gunk that builds up in a drain-pipe and slows the flow of water.

Causes of heart attack can also be as a result of blood clots that get stuck in a narrow part of an artery to the heart. Clots are more likely to form where atherosclerosis has made an artery narrow. Causes of heart attacks can be as result of sudden spasm (contraction) of the coronary artery. The spasm may be brought on by stress, cold or exertion. Also Carbon monoxide from generator fumes can cause a state of hypoxia (lack of oxygen) to the tissues which can affect the heart muscles leading to heart diseases.

Coronary arteries are arteries that supply blood to the heart. Any form of damage to the heart arteries over a period of time is called coronary artery disease (simply heart disease). Explaining the causes of heart disease further, any sudden blockage of the heart artery causes the complete or partial cut off of oxygen supply to the affected part of the heart muscle. Complete cut off of oxygen supply may lead to sudden death. This is what is termed coronary disease or heart disease.
