Decreased Cathepsin K Plasma Level may Reflect an Association of Osteopoenia/Osteoporosis with Coronary Atherosclerosis and Coronary Artery Calcification in Male Patients with Stable Angina.

Background: The aim of this study was to evaluate the plasma levels of bone turnover markers (BTMs) in male patients with stable angina depending on the bone mineral density (BMD), coronary atherosclerosis (CA) and coronary artery calcification (CAC).

Methods: We recruited 112 males with verified stable angina. All the patients underwent coronary angiography, multislice spiral computed tomography, and dual-energy X-ray absorptiometry.
