Coronary artery calcification is the result of calcium deposition in the coronary arteries. Coronary arteries are blood vessels that deliver blood supply to the heart for its nourishment and oxygen needs.
Calcification can occur from local tissue damage when calcium blood level is normal. Tissue damage triggers signals that attract calcium into the damaged tissue. There are several types of small-scale tissue damage that cause calcification.Blood vessel calcification is a common example.This type of calcification occurs in damaged tissues of the arteries as part of the condition known as atherosclerosis.inety-nine percent of the calcium in the body is used to build strong bones and teeth.
