To determine whether renal hemodynamic adaptations to high dietary sodium intake differ between salt-sensitive and salt-resistant patients with essential hypertension.
Studied 17 Black and 9 White patients with essential hypertension (N=26).
Placed participants on a low-sodium diet (20 meq/day) for 9 days, followed by a high-sodium diet (200 meq/day) for 14 days.
Administered slow-release nifedipine (30 mg/day) during the last 4 days of each dietary regimen.
Identified salt sensitivity in 11 Black patients, whereas all 9 White patients were salt-resistant.
Found similar mean arterial pressure, glomerular filtration rate, effective renal plasma flow, and filtration fraction between salt-sensitive and salt-resistant groups during the low-sodium diet baseline.
