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.
Fat (cholesterol). Atherosclerosis, or stiffening of the arteries, can cause build-up of fat inside the blood vessel walls, and the fat can become inflamed and calcified. This â¦ is called a calcified plaque. If the plaque gets vulnerable, the top of the plaque may rupture and the inside fat comes in contact with the circulating blood. This causes an immediate blood clot. If the plaque is in the coronary arteries, and if the blood clot blocks the coronary arteries, the result is a heart attack.
