[Chronological structure of arterial pressure in hypertensive patients on enalapril].
34 male patients with hypertension stage I and II aged 29-52 years (mean age 40.9 +/- 6.00) having mean 24-h arterial pressure (AP) above 135/85 mm Hg in mean daytime AP above 140/90 mm Hg and heart rate maximum 80 b/m entered the study of AP chronostructure in conditions of pure background and on enalapril treatment week 4, 8 and 12. The initial dose of the drug was 5 mg. Dose selection was controlled by 24-h AP monitoring. Enalapril was shown to significantly reduce mean daytime and 24-h AP as well as hyperbaric index, chronobiological time index, variability of systolic AP. The above dose selection brought more balanced AP lowering at daytime and at night. After 11 weeks of treatment no night-peakers were registered, the number of over-dippers decreased. Circadian rhythm of some hemodynamic parameters was characterized by a significant fall of rhythm average in unchanged acrophase and circadian AP amplitude indicating physiological action of enalapril.
