Study to Evaluate the Association of Testosterone Levels With Coronary Artery Calcification
Study to Evaluate the Association of Testosterone Levels With Coronary Artery in Patients With Stable Coronary Artery Disease
Studieoversikt
Detaljert beskrivelse
Coronary artery calcification (CAC) is associated with worse outcomes in patients with coronary artery disease (CAD), especially in old-aged population. Extensive CAC also increases the risk of procedure associated complications, such as stent migration, coronary artery perforation, dissection and thrombosis. The pathogenesis of CAC has not been fully explained. Recent evidence suggests that CAC share common pathways with bone formation. So, it can be presumed that risk factors contributing to bone formation and resorption activity also affect the development of CAC. Sex hormones is known to play an important role in bone development and in bone quality maintenance. Available data shows that androgens may affect differentiation, proliferation, and apoptosis of osteocytes, osteoclasts, and osteoblasts. Androgen receptor expression has been detected on different types of cells which contributing to the bone formation, such as osteoblastes, osteocytes and condrocytes, and androgen deprivation therapy results negative effects on bone mineral density in patients with metastatic prostate cancer. Osteoporosis, a systemic disease characterized by bone tissue loss, is more prevalent in oler men with low testosterone levels. In CAC, pathophysiological researches show that several vascular cell types, such as vascular smooth muscle cells, adventitial myofibroblasts and microvascular pericytes, have the potential to produce mineralized matrix and differentiate into osteoblasts. So, it can be postulated that androgens may play a similar role in the development of CAC.
Up to date, only limited data is available about the association between testosterone and CAC. A single-center study with relatively small sample revealed an inverse association between testosterone and CAC in non-obese men. The aim of this study was to investigate the association between testosterone and CAC measured as CAC score in old-aged male patients with CAD.
