Vascular wall calcification

Vascular wall calcification refers to the pathological deposition of calcium-phosphate mineral in the blood vessel wall, often occurring in the intimal (associated with atherosclerotic plaques and inflammation) and medial layers (common in diabetes and chronic kidney disease). The process involves vascular smooth muscle cells undergoing osteogenic transformation, matrix protein secretion, vesicle-mediated mineralization, and is driven by an imbalance between pro-calcific factors (hyperphosphatemia, inflammation, oxidative stress) and endogenous inhibitors (matrix Gla protein, pyrophosphate, fetuin-A). Vascular calcification contributes to arterial stiffness, hypertension, increased cardiovascular mortality, and loss of vessel compliance, and currently lacks targeted drug therapies. Vascular wall calcification is a clinically significant pathologic process rather than a conventional druggable molecular target. Disease management focuses on the modulation of contributing factors—serum minerals, inflammation, and osteogenic signaling in vascular smooth muscle cells—rather than direct molecular inhibition.
