BACKGROUND AND AIM OF THE STUDY Calcific aortic stenosis (AS) is the most frequently acquired valvular disease of the elderly in the Western world. A genetic background for AS has been proposed. The deposition of calcium hydroxyapatite is the key problem of valve calcification; vitamin D and parathyroid hormone are major factors in calcium homeostasis. The(More)
Calcific aortic valve stenosis, the most frequent heart valve disorder in developed countries, is an actively regulated process with similarities to bone formation. Fetuin-A has recently been identified as a potent circulating inhibitor of calcification. While several studies involving patients with end-stage renal disease have shown an association between(More)
Data suggest a link of aortic stenosis (AS) with calcium and bone metabolism. To further investigate this, the following parameters were analyzed in 38 patients with severe AS and in 38 age- and gender-matched controls, without obstructive coronary artery disease and with preserved renal function: calcium, phosphate, 1,25(OH(2))-vitamin D(3), intact(More)
