title: [Correlation between the parameters of 24-hour monitoring of arterial pressure and changes in arterial wall structure based on the results of a prospective trial].
abstract: OBJECTIVE
  To evaluate prognostic value of 24-h monitoring of blood pressure (BPM-24) for assessment of structural changes in arterial walls in patients with essential hypertension living in West Siberia.
  
  
  METHODS
  In the course of 5-year prospective study we made two extended clinical and device examinations with use of BPM-24 and ultrasonic measurements of arterial intima-media complex (IMC) in 160 patients (mean age 48.97+/-8.18 years).
  
  
  RESULTS
  An independent significant correlation was found between initial drop of the circadian index (CI) of blood pressure, systolic blood pressure (SBP)/diastolic blood pressure (DBP) at night (r = 0.24/0.22, p = 0.012/0.024) and thickness of IMC in 5 years (r = -0.28/-0.30, p = 0.004/ 0.002). The risk of increased thickness of arterial wall in the group with abnormal CI was 1:4. There was no relationships between IMC increase and baseline office blood pressure (r = 0. 18/0.12, p = 0. 057/0.188). In evaluation of office BP effects on progression of arterial atherosclerosis insignificant correlation coefficients for SBP/DBP were obtained (r = 0. 18/0.18, p = 0. 150/0.149) contrary to BPM-24 parameters: mean circadian SBP (r = 0.22, p = 0.046) and heart rate (r = 0.23, p = 0.038), SBP temporal index for 24 hours (r = 0.24, p = 0.035).
  
  
  CONCLUSIONS
  . BPM-24 parameters are more significant predictors of structural changes in arterial wall than standard office blood pressure. This allows calculations of possible risk of such changes.
