Abstract

A bidirectional relationship between hypertension and kidney disease, with one exacerbating the effect of the other, is well established. Elevated blood pressure (BP) is a well-recognized, modifiable risk factor for cardiovascular (CV) disease as well as for development and progression of chronic kidney disease and, therefore, the identification of optimal BP target is a key issue in the management of renal patients. Recent large trials and real life cohort studies have indicated that below a definite BP value renal protection seems to plateau and too low levels may even be associated with a paradoxical increase in renal morbidity, thus reviving the debate about the so called BP -renal function J-curve relationship. Existing evidence supports a systolic target around 130 mm Hg to combine both renal and CV protection and possibly lower levels in the presence of overt proteinuria.
