Coronary Artery Disease is commonly known as Heart Disease or Atherosclerosis. In coronary artery disease, plaque builds up inside the arteries. These plaques are formed by fats and cause the arteries to harden. The deposits are made of fat that came from the food that we eat. These fat deposits narrow the arteries and impede circulation. The narrowing of the arteries also causes high blood pressure because the body tries to compensate for the inadequate supply of blood throughout the system.

Fat deposits in arteries are very dangerous. Aside from the fact that these arteries should not be present in the arteries, these deposits also cause a disturbance in the heart’s normal functioning. The blood vessels with fat deposits are narrowed. It also causes hardening that inhibits the normal elastic function of the vessels. It causes decreased blood flow to the heart which results in chest pain called angina.

Angina occurs when the heart doesn’t have enough supply of oxygen for it to function properly. The heart muscles need oxygen for them to function because it is necessary for the energy formation of muscles that it uses for working. Without adequate energy, muscles will fail to work. Angina is described as a painful squeezing feeling in the chest that is also felt in the jaws, extremities and the back.

A heart attack occurs after angina. The heart ceases to function because its muscles did not receive much oxygen. Certain muscles in the heart have died because of the inadequate supply of oxygen and therefore the remaining muscles have to compensate for the loss. Compensation gives extra workload and fatigue, causing it to stop.

There are a lot of factors that cause coronary heart disease. One of them is a major risk factor that can’t be avoided and that is family history. If your family is known to have coronary heart disease, then you will likely also have the condition. Little is known about this theory but it is very consistent among patients with coronary heart disease.
