title: Low atrial natriuretic peptide plasma concentrations in 100 patients with essential hypertension.
abstract: Although atrial natriuretic peptide (ANP) plays a key role in electrolyte and volume regulation and causes direct vasorelaxation, controversial results have been reported in hypertensive patients. We studied 58 men and 42 women, aged 19 to 78 years, with essential hypertension (blood pressure: 150 to 210/95 to 110 mm Hg) using 24 h blood pressure recording, treadmill exercise and x-ray of the chest. In 70 patients ANP plasma concentrations were found to be completely within the normal range of healthy controls (17 to 38 fmol/mL; n = 50) and 52% were detected within the lower third or even below the normal range. In mild to moderate essential hypertension a diminished secretion of ANP may be responsible for an elevated blood pressure in these patients.
