Text: Although all neurohormones except epinephrine were increased compared with values in age-matched control subjects, plasma norepinephrine (301 + / - 193 vs. 222 + / - 87 pg/ml, p < 0. 001), renin activity (3. 0 + / - 3. 7 vs. 1. 2 + / - 1. 2 ng/ml per h, p < 0. 001), arginine vasopressin (1. 9 + / - 6. 9 vs. 0. 7 + / - 0. 3 pg/ml, p < 0. 001) and atrial natriuretic peptide (75 + / - 75 vs. 21 + / - 9 pg/ml, p < 0. 001) values ranged from normal to very high, indicating a wide spectrum of neurohumoral activation.
