What is the relationship between systolic BP and stroke risk in CKD patients?
A cohort study of 860 US veterans (comprising mainly men) with CKD (GFR o60 and a subset with GFR o30 ml/min/) showed a J-shaped relationship between stroke and systolic BP, with lowest stroke risk in the range of systolic BP between 120 and 129 mm Hg, and higher risk above and below this.
