    Abstract:
    Plasma atrial natriuretic factor (ANF), blood pressure, age, plasma renin activity and creatinine were measured in 50 normal volunteers, 141 essential hypertensives, 35 patients with chronic renal failure who had never been dialysed and 27 patients with end-stage renal failure on constant haemodialysis. Plasma ANF was correlated positively with age in the normal group (r = 0.52, P less than 0.01) and with blood pressure in the essential hypertensives (r = 0.50, P less than 0.001), and negatively with renin in the normal and end-stage renal failure patients (r = -0.47, r = -0.34; P less than 0.01, P less than 0.05, respectively). When patients without left ventricular hypertrophy were matched for age and blood pressure, plasma ANF was significantly different between the essential hypertensives and the normal and end-stage renal failure patients (16 +/- 1, 38 +/- 6 and 148 +/- 24 pmol/l, respectively; P less than 0.001). Cardiac factors are therefore not the only determinant of circulating plasma ANF in humans with chronic renal failure.
