Coronary heart disease is a common term for the buildup of plaque in the heart’s arteries that could lead to heart attack. But what about coronary artery disease? Is there a difference?  

The short answer is often no — health professionals frequently use the terms interchangeably.

However, coronary heart disease , or CHD, is actually a result of coronary artery disease, or CAD, said Edward Fisher, M.D., Ph.D., an American Heart Association volunteer who is the Leon H.

With coronary artery disease, plaque first grows in the coronary arteries until the blood flow to the heart’s muscle is limited. View an illustration of coronary arteries. This is also called ischemia. It may be chronic, caused by narrowing of the coronary artery and limitation of the blood supply to part of the muscle. Or it can be acute, resulting from a sudden plaque that ruptures.

The traditional risk factors for coronary artery disease are high LDL cholesterol, low HDL cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to Fisher. Obesity may also be a risk factor. “Coronary artery disease begins in childhood, so that by the teenage years, there is evidence that plaques that will stay with us for life are formed in most people,” said Fisher, who is also editor and chief of the American Heart Association journal, ATVB. “Preventive measures instituted early are thought to have greater lifetime benefits.Healthy lifestyles will delay the progression of CAD, and there is hope that CAD can be regressed before it causes CHD.” Living a healthy lifestyle that incorporates good nutrition, weight management and getting plenty of physical activitycan play a big role in avoiding CAD.  “Coronary artery disease is preventable,” agreed Johnny Lee, M.D., president...
