Cardiovascular events are the main causes of mortality in dialysed patients. Traditional risk factors such as hypertension, aging, smoking, diabetes, and abnormal lipid metabolism does not fully explain the high frequency of cardiovascular disease in renal patients, indicating that some other distinct pathogenesis may be involved. Vascular calcification have been associated with high cardiovascular morbidity and mortality in chronic kidney disease (CKD) patients. It is an active process that resembles osteogenesis, regulated by bone proteins and osteoblast-like cells. Elements involved in the pathogenesis are: the risk factors that initiates the process, the promoters released and overexpressed and the dysregulation of the inhibitor factors of extraskeletal calcifications. Although researches in the past decade have greatly improved our knowledge of the multiple factors and mechanisms involved in vascular calcification, many questions remain unanswered.
