Cardiovascular biomarkers in chronic kidney disease

Abstract

Chronic kidney disease (CKD) is a growing public health problem worldwide. The high incidence of cardiovascular diseases (CVD) and high mortality rates in patients with CKD, particularly in advanced stages, bring a rationale for better risk stratification in this population. Known risk factors such as inflammation, oxidative stress, anemia, and bone mineral disorders contribute by large to the high incidence of cardiovascular complications diagnosed in patients with CKD. Metabolic biomarkers related to these events might be valuable in predicting CVD. The accurate assessment of cardiovascular risk at an early stage could facilitate more aggressive and better tailored treatment of selected patients in order to reduce event rates. In this review, we discuss the epidemiology of CKD and CVD, the mechanisms of vascular calcification, as well as established and emerging laboratory biomarkers for the cardiovascular risk assessment in CKD.
