Office and 44-hour ambulatory blood pressure and central haemodynamic parameters in the patients with end-stage renal diseases undergoing haemodialysis

AIM: To assess the incidence of blood pressure (BP) control and various phenotypes of BP by comparing the results of office and 44-hour ambulatory brachial and central BP measurement in patients with end-stage renal disease (ESRD) on program hemodialysis (HD). MATERIALS AND METHODS: In 68 patients ESRD receiving renal replacement therapy we evaluated office peridialysis BP and performed 44-hour ambu latory monitoring (ABPM) of brachial and central BP during peridialysis period using a validated oscillometric device BPLabVasotens (OOO "Petr Telegin"). Results were considered statistically significant with p<0.05. RESULTS: The frequency of control of peripheral office BP before the HD session was 25%, after - 23.5%; control of central BP - 48.6% and 49%, respectively. According to office measurement the frequency of systolic-diastolic hypertension was 44.1%, isolated systolic hypertension - 25%, isolated diastolic hypertension - 5.9%. The values of peripheral and central office systolic BP (SBP) before and after HD were not consistent with the corresponding mean and daily SBP levels for 44 hours and for the first and second days of the interdialysis period. The frequency of true uncontrolled arterial hypertension (AH) according to peripheral ABPM was 66.5%, masked uncontrolled AH - 9%. Circadian rhythm abnormalities for 44-h peripheral BP were detected in 77%, for central - in 76%. In 97% of patients agreement between phenotypes of the daily profile of peripheral and central BP was observed. 73% of patients had a significant increase in peripheral and central SBP and pulse pressure (PP) and an increase in the proportion of non-dippers from the 1st to the 2nd day. CONCLUSION: Patients with ESRD on HD were characterized by poor control of BP control and predominance of unfavourable peripheral and central ambulatory BP phenotypes. A single measurement of clinical peripheral and central BP in the peridialysis period was not sufficient to assess the control of hypertension in this population. The 24-h BP profiles in the 1st and 2nd days of interdialysis period had significant differences.
