Optimal blood pressure (BP) is uncertain in patients with chronic kidney disease (CKD), which is often associated with high pulse pressure. These investigators examined BPs and outcomes in 651,749 U.S. veterans with non–dialysis-dependent CKD (mean age, 74; 88% white; 9% black) treated at Veterans Affairs healthcare facilities from October 2004 through September 2006. At baseline, 43% of participants had diabetes, and mean glomerular filtration rate was 50.4 mL per minute; mean baseline systolic BP (SBP) and diastolic BP (DBP) were 135 mm Hg and 72 mm Hg, respectively.
During a median follow-up of 5.8 years, 238,640 patients died. The associations of both SBP and DBP with mortality were U-shaped. Optimal SBP was in the approximate range of 1…
