Definitions for "Coronary heart disease"
a group of conditions where the supply and demand for oxygenated blood to the heart is not balanced. It is usually caused by reduced blood supply to the heart.
coronary heart disease (also known as ischemic heart disease): a type of heart disease in which the arteries that supply blood to the heart muscle become narrowed or blocked by plaque, reducing or stopping the blood flow to the heart muscle, depriving the muscle of needed oxygen. Such blockages may result in angina or a heart attack.
When the walls of the coronary arteries become narrowed by a gradual build-up of fatty material called atheroma. When atheroma affects the coronary arteries, it can cause angina, heart attack or sudden death.
