CONTEXT Inverse associations are reported between circulating 25-hydroxyvitamin D and visceral adiposity. The effects of vitamin D levels on atherosclerosis are unknown. OBJECTIVE The objective of this study was to test for relationships between vitamin D, adiposity, bone density, and atherosclerosis in African-Americans. DESIGN Circulating 25-hydroxyvitamin D, 1,25 dihydroxyvitamin D, inta...
Osteoprotegerin (OPG) is a kind of tumor necrosis factor, which is related to bone metabolism and vascular calcification. The increase of Osteoprotegerin concentration in serum is related to cardiovascular diseases in humans. The purpose of this study was to figure out the relevance between osteoprotegerin in serum and carotid calcification. Serum OPG concentrations were compared in 145 patient...
The pathogenesis of valvar calcification, which complicates the course of cardiac valve disease and also affects tissue valve prostheses, is incompletely understood. The present work explores the possible role of the vitamin K-dependent, calcium-binding amino acid, gamma-carboxyglutamic acid (Gla) in valve mineralization. Gla is normally found in the vitamin K-dependent clotting factor proteins...
This study investigates the clinical relevance and therapeutic implications of OCT identification intracoronary superficial calcified plates (SCPs) in acute coronary syndromes (ACSs). In 70 consecutive ACS patients (pts), we studied three main underlying mechanisms: plaque erosion (PE), rupture eruptive nodule (CN). The PE lesions, occurring on an intact fibrous cap overlying a heterogeneous su...
