Abstract
Patients with sleep apnea syndrome (SAS) have an increased incidence of cardiovascular diseases, e.g., arterial hypertension [1, 2]. Especially the physiological decrease in systemic blood pressure at night is often missing in patients with obstructive sleep apnea [2]. This is possibly produced by an increased sympathetic activity in response to hypoxemia during apnea. The urinary excretion of catecholamines is also increased in patients with SAS [2, 3] and the diurnal rhythm of excretion is lost [2]. Hitherto there have been no reports about the pattern of the plasma catecholamines in patients with SAS during sleep.
