Increased Sodium Intake Correlates With Greater Use of Antihypertensive Agents by Subjects With Chronic Kidney Disease

Hypertension is a common disease in patients with chronic kidney disease (CKD) and predisposes to heart disease, stroke, and progression of renal failure. In the general population, sodium restriction has been shown to improve blood pressure (BP) control, but this is not widely recommended in CKD patients. The aim of this study was to assess the sodium balance in a CKD clinic and its effect on BP management. We retrospectively reviewed charts from June 1998 through to June 2003 and included all patients with an estimated glomerular filtration rate (GFR) of
