Depends on who's asking. For the Federal government, gross income is income from all sources- earned and unearned. 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.
Vascular calcification is a pathologic process that occurs in response to dysregulated or inappropriate environmental stimuli (e.g., advancing age, atherosclerosis, certain metabolic disorders [e.g., CKD, diabetes, chronic inflammatory disease such as systemic lupus erythematosus and other rheumatic diseases]) and in rare genetic diseases (e.g., Keutel syndrome, a rare autosomal recessive condition characterized by abnormal cartilage calcification) (1,2).
