Cardiovascular co-morbidity in chronic kidney disease:Current knowledge and future research needs

Chronic kidney disease(CKD) is recognised as a health concern globally and leads to high rates of morbidity,mortality and healthcare expenditure.CKD is itself an independent risk factor for unfavorable health outcomes that include cardiovascular disease(CVD).Coronary artery disease is the primary type of CVD in CKD patients and a significant cause of death among renal transplant patients.Traditional and non-traditional risk factors for CVD exist in patients with CKD.Traditional factors include smoking,hypertension,dyslipidemia and diabetes which are highly prevalent in CKD patients.Non-traditional risk factors of CKD are mainly uraemiaspecific and increase in prevalence as kidney function declines.Some examples of uraemia-specific risk factors that have been well documented include low levels of haemoglobin,albuminuria,and abnormal bone and mineral metabolism.Therapeutic interventions targeted at more traditional risk factors which contribute to CVD,have not had the desired effect on lowering CVD events and mortality in those suffering with CKD.Future research is warranted to delineate clear evidence to the benefit of modifying non-traditional risk factors.
