What is the Origin of Coronary Artery Calcium?

The term combines "coronary artery," the vessels supplying the heart muscle, and "calcium," the mineral component that deposits in advanced atherosclerotic lesions. The clinical significance of this finding became prominent with the development of fast, high-resolution CT scanners that could accurately quantify the calcification, leading to the establishment of the Agatston score for standardized risk assessment.

What is the Mechanism of Coronary Artery Calcium?

The deposition of calcium is a late-stage process in the development of atherosclerosis, a chronic inflammatory disease of the arterial wall. Macrophages engulf oxidized lipids, forming foam cells and initiating an inflammatory cascade that leads to the formation of a fibrous cap over a lipid core. Over time, microcalcification begins in the necrotic core and eventually progresses to macroscopic calcium deposits, representing a stable but significant marker of disease burden and vascular stiffening.

Coronary Artery Calcium

Meaning

Coronary Artery Calcium (CAC) refers to the presence and quantification of calcified atherosclerotic plaque within the walls of the coronary arteries, measured typically by a non-contrast computed tomography (CT) scan. This score serves as a highly specific and independent biomarker for the total burden of coronary atherosclerosis, reflecting a cumulative history of plaque formation. Clinically, a high CAC score indicates an increased future risk of cardiovascular events, necessitating aggressive risk factor modification and therapeutic intervention.
