[Characteristics of circadian rhythms of arterial pressure and heart rate in hypertensive subjects living in the North of the Tiumen' region]
Abstract
Chronostructure of arterial pressure (AP) and heart rate (HR) was studied in 62 residents of Tumen Region North with arterial hypertension (AH) aged 18-50 years and 56 AH controls living in the temperate zone. The groups were matched by age, sex, AH duration, office systolic and diastolic arterial pressure (SAP and DAP, respectively). Circadian AP profile with night hypertension was registered in 76.6 and 28.3% patients of the test and control groups, respectively. Test group patients had more pronounced defects in DAP and HR chronostructures. Thus, AH patients living in the Tumen North demonstrate abnormal circadian AP profile and AP and HR chronostructure. This may be prognostically important for development of cardiovascular complications.
