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.

If you are living a sedentary or inactive lifestyle, it is now time to change your ways and to do some serious physical work. A sedentary lifestyle will increase your risk of developing heart disease because without physical activities, your heart muscles will become flabby and weak. You need to do some simple exercises to tone your heart muscles and make it strong.

Obesity also increases the chance of having heart disease. Fat is a major contributory factor for the development of heart disease and people who are obese or overweight have a lot of fat stored in their bodies. These fats need to be burned down to lose weight and prevent having serious complications such as heart disease.

All in all, heart disease is caused by living an inappropriate lifestyle. Keep in mind that no matter how rich you are, it is not an excuse for you not to work. Exercise should also be a regular habit so that your muscles will be tougher and can reach their optimum functioning.
