URINARY SODIUM, POTASSIUM AND CREATININE EXCRETION IN HYPERTENSIVE AND NORMOTENSIVE AUSTRALIANS

Abstract

Studies were made in urine obtained from people attending for routine measurement of blood pressure in a screening programme. Subjects with diastolic blood pressure between 95 and 109 mm Hg excreted significantly more sodium than the group with diastolic blood pressure below 90 mm Hg. Urine volumes, potassium excretion and creatinine excretion did not differ significantly between the groups.
