Atherosclerosis is a type of arteriosclerosis caused by a build-up of plaque in the inner lining of an artery.

Chronic inflammation damages the inside of coronary arteries and leaves them prone to plaque that clogs the blood vessels. That leads to clots that cause heart attacks.

Angina pectoris occurs when the heart muscle doesn't receive enough blood and oxygen for a given level of work.

Angina is a condition characterized by recurring pain or discomfort in the chest. Not all chest pain or discomfort is angina, but all chest pain should be checked out by a doctor.

Some symptoms may indicate the possibility of a serious condition and should be evaluated immediately by a health care provider.

A person with coronary heart disease has an accumulation of fatty deposits in the coronary arteries. These deposits narrow the arteries and can decrease or block the flow of blood to the heart.
