Chronic kidney disease and cardiovascular risk

Chronic kidney disease (CKD) is a global public health concern, and there is emerging a strong relationship between CKD and increased cardiovascular disease (CVD) risk. CKD in the presence of other co-morbidities such as type 2 diabetes mellitus (T2DM) and hypertension (HTN) can lead to early progression to end-stage renal disease (ESRD/stage V CKD) and confer a greater risk for CVD morbidity and mortality. CVD events are the leading cause of premature death in patients with CKD, even before their progression to ESRD, with the rate of CVD progression being twice as common compared with the general population. The higher mortality from CVD persists even after adjusting for most of the traditional risk factors, suggesting the possible contributions of uremia-related, nontraditional risk factors. This has led to the current understanding that the pathophysiology of CVD in CKD involves a complex interplay of both the traditional as well as nontraditional, uremia-related risk factors. This review will elaborate on the pathophysiology of CVD in CKD and will discuss the role of microalbuminuria (MAU)-proteinuria as a potential diagnostic and prognostic tool for CVD in CKD risk assessment.
