Hypertension and Kidney Disease: What Do the Data Really Show?

Abstract

Hypertension is the most common co-morbidity in chronic kidney disease (CKD) and the optimal target BP to prevent CKD progression has been hotly debated. Prior recommendations by various groups for BP targets for CKD in the range of less than 130/80mm Hg have been based on the assumed benefits of lower BP in this population with exceedingly high risk for cardiovascular disease (CVD). Although there is suggestive data that lower BP may be helpful in patients with proteinuria and CKD, studies not directly link a treatment-related reduction in proteinuria to a benefit in kidney outcomes. There are ongoing studies which will provide more data on BP targets in CKD. Based on the currently available data we recommend a BP goal of less than 140/90mm Hg in all patients with CKD.
