Coronary heart disease

Coronary heart disease is caused by [cholesterol plaques]? (caused by the build of up of cholesterol) that either cause an intrinsic limitation in blood flow to the heart or a functional limitation of blood flow to the heart. In the latter case this is known as angina. Limitation of blood flow to the heart causes ischemia (cell starvation secondary to a lack of oxygen) of the myocardial cells. When myocardial cells die from lack of oxygen, this is called a [Myocardial infarction]? a [heart attack]?).
