Vascular calcification is the buildup of calcium deposits in the blood vessels, which can lead to stiffening and narrowing of the arteries. This process can occur due to various factors, including aging, high blood pressure, and conditions like diabetes or chronic kidney disease. As calcium accumulates, it can disrupt normal blood flow and increase the risk of cardiovascular diseases, such as heart attacks and strokes. Early detection and management of risk factors are essential to prevent or slow down the progression of vascular calcification.
