Heart Disease CAD Coronary Artery Disease Term Paper

Heart Disease (CAD: Coronary Artery Disease)

Online web site HeartPoint defines Coronary Artery Disease as Coronary artery disease generally refers to the buildup of cholesterol in the inside layers of the arteries. As shown here, this will slowly narrow the flow of blood through the vessel, and the muscle it supplies will not get enough blood. The plaque weakens the wall. As shown in the lower artery, a crack may develop in the plaque and a blood clot may form - this is the mechanism of most heart attacks.
