Misclassification of blood pressure of Vietnamese adults when only a single measurement is used

Background Blood pressure measurement (BPM) is one of the most often performed procedures in clinical practice, but especially office BPM is prone to errors. Unattended automated office BPM (AOBPM) is somewhat standardised and observer-independent, but time and space consuming. We aimed to assess whether an AOBPM protocol can be abbreviated without losing accuracy. Design In our retrospective single centre study, we used all AOBPM (AOBPM protocol of the SPRINT study), collected over 14 months. Three sequential BPM (after 5 minutes of rest, spaced 2 minutes) were automatically recorded with the patient alone in a quiet room resulting in three systolic and diastolic values. We compared the mean of all three (RefProt) with the mean of the first two (ShortProtA) and the single first BPM (ShortProtB). Results We analysed 413 AOBPM sets from 210 patients. Mean age was 52±16 years. Mean values for RefProt were 128.3/81.3 mmHg, for ShortProtA 128.4/81.4 mmHg, for ShortProtB 128.8/81.4 mmHg. Mean difference and limits of agreement for RefProt vs. ShortProtA and ShortProtB were -0.1±4.2/-0.1±2.8 mmHg and -0.5±8.1/-0.1±5.3 mmHg, respectively. With ShortProtA, 83% of systolic and 92% of diastolic measurements were within 2 mmHg from RefProt (67/82% for ShortProtB). ShortProtA or ShortProtB led to no significant hypertensive reclassifications in comparison to RefProt (p-values 0.774/1.000/1.000/0.556). Conclusion Based on our results differences between the RefProt and ShortProtA are minimal and within acceptable limits of agreement. Therefore, the automated procedure may be shorted from 3 to 2 measurements, but a single measurement is insufficient.

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.
