This can cause thickening of the heart muscle and stiffening. In early phases, this can cause shortness of breath and chest discomfort.
Aortic calcification: An early sign of heart valve problems?
2024年7月10日 · Aortic valve calcification is a condition in which calcium builds up on the aortic valve. Buildups of calcium can cause the valve opening to become narrow. Severe narrowing can reduce or block blood flow through the aortic valve — a condition called aortic valve stenosis. Aortic valve calcification may be an early symptom of heart disease ...
