Abstract
The 24-h urinary excretion of free catecholamines was evaluated in: 62 healthy and 20 hypertensive (primary hypertension, stage 1 and 2) male subjects, ≦39 years of age, and in 64 healthy and 44 hypertensive (primary hypertension, stage II and III) male subjects ≧40 years of age. Noradrenaline excretion correlates positively with the age, based on the data of all 190 subjects (r=0.29,Pr=0.37,Pr=0.28,Pn=190). The younger hypertensives (≦39 years of age) show a slightly but not significantly higher noradrenaline excretion; this, however, is significantly higher in the group of older hypertensive subjects (P<0.05; ≧40 years of age). No significant differences are recognizable for adrenaline and dopamine excretion between normotensive and hypertensive subjects.
