Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women.
CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the build-up of cholesterol and other material, called plaque, on their inner walls. This build-up process is called atherosclerosis. As it grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when the plaque tears and the vessel wall is even slightly exposed. The body react to create a clot to prevent blood loss, but this sudden creation of the blood clot ceases the blood supply in this vessel and any heart muscle that supposed to get this blood cannot get it, and therefor damage to the heart muscle is performed.
Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the heart can't pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.
