Unearned income is your money making money- investments, dividends, capital gains, sale of property. Earned income is, well, what you actually toiled to attain, like wages, consultation fees, jury duty payment, etc.
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.
A coronary calcium scan is a test that looks for specks of calcium in the walls of the coronary (heart) arteries. These specks of calcium are called calcifications (KAL-sih-fih-KA-shuns). Calcifications in the coronary arteries are an early sign of coronary heart disease (CHD).CHD is a disease in which a waxy substance called plaque (plak) builds up in the coronary arteries.igure A shows the position of the heart in the body and the location and angle of the coronary calcium scan image. Figure B is a coronary calcium scan image showing calcifications in a coronary artery.
