Calcium management in cardiology involves both dietary calcium intake and medical management of arterial calcification. While adequate dietary calcium is essential for bone health and normal heart function, excessive calcium supplementation has been linked to an increased risk of cardiovascular events like heart attacks and should be limited, especially if intake is primarily through supplements rather than diet. Management of existing arterial calcification (coronary artery calcification, CAC) focuses on assessing its severity and treating underlying disease, often using imaging like CT scans and procedures such as atherectomy or angioplasty.
