[Diurnal profile of arterial pressure during sleep deprivation in patients with hypertensive disease receiving antihypertensive therapy].

Diurnal profile of arterial pressure during sleep deprivation was studied by 24 hr AP monitoring in 40 patients with grade I-II AH (hypertensive disease) and slightly or moderately elevated AP. Group 1 included 10 patients who did not receive antihypertensive therapy. Group 2 (n = 30) was treated with 10 mg/d lisinopril either in the morning or in the evening. Patients of group 3 (n = 10) were given b-blocker metoprolol (35 mg at 22.00). AP monitoring was performed in duplicate (with night sleep deprivation and without it). Sleep deprivation resulted in the inverted AP profile (mean night-time AP higher than the mean daytime value) whether the patients were treated with long-acting lisinopril or with short-acting metoprolol given immediately before sleep deprivation. Mean daily AP in case of night deprivation was higher than under normal conditions.
