Abstract
To investigate the circadian variations of plasma atrial natriuretic peptide (ANP) and its relationship to arterial blood pressure, plasma renin activity and aldosterone level, we determined 24-h blood pressure in 14 healthy volunteers. Plasma ANP concentration, renin activity and aldosterone levels were measured every 3 h by radioimmunoassay. We found no significant circadian variation of plasma ANP level (pg/ml) (daytime level, 62 ± 24 vs. night-time level, 57 ± 19, P = 0.146) and plasma renin level (ng/ml/h) (1.32 ± 0.78 vs. 1.15 ± 0.57, P = 0.148), but there was diurnal change of blood pressure (mmHg) (systolic, 122 ± 7 vs. 116 ± 11, P < 0.001; diastolic, 80 ± 11 vs. 72 ± 11, P = 0.025) and plasma aldosterone level (pg/ml) (86 ± 42 vs. 62 ± 37, P < 0.001). The blood pressure and aldosterone levels reached maxima (11:00 h and 08:00 h, respectively) before that of ANP (17:00 h) and then decreased together until the nadir at 02:00 h. This might indicate that elevation of arterial blood pressure and plasma aldosterone level stimulate release of ANP under normal physiological conditions. ? 1994.
