Chronic kidney disease is a growing public health problem, as its prevalence and incidence have almost doubled over the last three decades. Chronic kidney disease is defined as the presence of an estimated glomerular filtration rate < 60 ml/min/1.73 m² and/or proteinuria ≥ 0.150 g/24 h. It has been demonstrated that both proteinuria and reduction in estimated glomerular filtration rate can predict the development of fatal and non-fatal cardiovascular events, regardless of traditional cardiovascular risk factors, namely blood pressure, smoking habit, cholesterol, age, gender. This relationship is found in the general population, high-risk cohorts and in patients referred to Nephrologists (tertiary care). The accuracy by which proteinuria or estimated glomerular filtration rate can predict these events, exceeds that obtained by the combination of all the other traditional risk factors. These important findings have led to chronic kidney disease being considered as a cardiovascular risk equivalent. Although this needs further investigation, a great effort has been made to reduce the cardiovascular risk in chronic kidney disease patients. Indeed, many clinical trials have been carried-out testing the effect of antihypertensive, proteinuria-lowering, lipid-lowering and hypoglycemic agents on cardiovascular risk protection. All these trials reduced, but did not eliminate, the overall cardiovascular risk. Future studies should be undertaken to identify high cardiovascular risk patients and novel therapeutic targets for cardiovascular protection in chronic kidney disease patients.
