Atherosclerosis, sometimes called "hardening of the arteries," occurs when fat (cholesterol) and calcium build up in the wall of the arteries, forming a substance called plaque. Over time, the fat and calcium buildup may narrow the artery and reduce blood flow through it.
A major part of treating atherosclerosis and coronary artery disease involves lifestyle changes (such as quitting smoking) and medicines to help reduce high cholesterol, control high blood pressure, and manage other things that increase a person's risk of heart attack, stroke, and other complications.
