A 24-h arterial pressure profile in patients with arterial hypertension living in Tyumen North

Abstract


Aim. To study a 24-h profile of arterial hypertension and affection of target organs in hypertensive population of the Tyumen North.
Material and methods. 62 patients (43 men and 19 women, age 18-50 years) with arterial hypertension (AH) living in the North of the Tyumen region entered the test group. The control group consisted of 56 AH patients (36 men and 20 women) matched by age. They lived in the zone of moderate climate (in Tyumen). 24-h arterial pressure (AP) monitoring was made starting on day 2 of the patients' arrival in Tyumen. Echocardiography was made on the arrival day. The examination of the groups was conducted against "clean" background.
Results. The groups did not differ significantly by age, sex, AH duration, office systolic and diastolic pressure (SP, DP). However, 37patients from the test group on arrival in Tyumen showed normalization of both office AP and mean 24-h AP. 25 patients from this group sustained high office and mean 24-h AP. An abnormal 24-h AP profile with nocturnal hypertension was recorded in 76.6% of the test group and 28.31% patients of the control group. Left ventricular hypertrophy was significantly more pronounced in the test group than in the control one.
Conclusion. In 2/3 patients from the North with AH stage I and 2 office AP and mean 24-h AP normalized upon their arrival to the zone of moderate climate but their left ventricular hypertrophy was more severe and changes in a 24-h AP profile with nocturnal hypertension persisted.
