Effect of periphral vessel congestion on diastolic blood pressure measurements with auscultatory method

BackgroundKey benefits of home-based blood pressure measurements are the potential to reduce the risk of ‘white coat hypertension’, encouraging patients to take ownership of their condition and be more actively involved in their long-term condition care, and to move work out of the doctor’s office.AimTo assess whether performing 20 resting blood pressure measurements over a 2-day period would provide a reliable, stable representation of patients’ resting systolic and diastolic blood pressure. Following clinician recommendation, each participant completed the Stowhealth home blood pressure monitoring procedure.MethodOne thousand and forty-five participants (mean age 66±13 years, 531 women and 514 men) completed the procedure, of 10 resting measurements per day, for 2 days (20 resting systolic and diastolic blood pressure readings in total). All measurements were made using automated oscillometric monitors.ResultsWithin-patient coefficient of variation for the entire participant cohort was 8% for systolic blood pressure (cohort mean 141±11 mm Hg), and 8% for diastolic blood pressure (cohort mean 79±6 mm Hg). There were no significant differences between the first and second day, for either systolic (142±1vs 141±1 mm Hg, respectively, p>0.05) or diastolic blood pressures (79±1vs 78±1 mm Hg, respectively, p>0.05 in both cases).ConclusionThe overall duration of home blood pressure monitoring may be able to be reduced to just 48 hours. This method would offer meaningful time saving for patients, and financial and time benefits for doctors and their surgery administration.

Significant Difference

Indirect blood pressure measurements were compared in 28 conscious cats using Doppler and oscillometric blood pressure-measuring devices. Ten cats were used to compare Doppler measurements between two examiners and 18 cats were used to compare Doppler and oscillometric measurements. The Doppler machine obtained systolic and diastolic blood pressure readings in 100% and 51% of attempts, respectively. With the oscillometric machine, systolic and diastolic blood pressure readings were obtained in 52% of the attempts. With the Doppler, measures of mean systolic blood pressure between two examiners were positively correlated, but there was no correlation for diastolic blood pressure measures. When comparing the results obtained by Doppler and oscillometric machines there was no significant difference between mean systolic blood pressure readings, but the oscillometric machine produced significantly higher estimates of diastolic blood pressure. In both cases, the standard deviations for the oscillometric machine were considerably larger than those for the Doppler machine. The first reading of systolic blood pressure obtained with the Doppler machine was an excellent predictor of the mean of five readings, but this was not so for the oscillometric machine. It took less than 5 min to obtain five readings in 37.5% of cases with the Doppler machine but this was true for only 5% of cases with the oscillometric machine. Two cats with ophthalmological lesions consistent with systemic hypertension were identified. In these two patients, systolic blood pressure measurements were between 200 and 225 mmHg when measured by Doppler, and between 140 and 150 mmHg when measured by the oscillometric machine. This suggests that a lower reference range for normal systolic blood pressure values should be used for the oscillometric device.

Background: Abnormal 24-hour ambulatory blood pressure monitoring (ABPM) patterns have been associated with diminished cognitive function in hypertensive and very elderly populations. The relationship between ABPM patterns in community-living older adults is unknown. Methods: We conducted a cross-sectional study in which ABPM, in-clinic blood pressure, and cognitive function measures were obtained in 354 community living older adults. We used multiple linear regression to examine the associations of in-clinic and ABPM with the Montreal Cognitive Assessment (MoCA [range 0-30 with lower levels indicating worse cognition]), adjusting for age, sex, race/ethnicity, education, and comorbid medical conditions. Results: The mean age was 72 years, 68% were female, and 13% were African American; 45% had a diagnosis of hypertension. In-clinic blood pressure measurements were not significantly associated with cognitive function after adjustment. In contrast, less nighttime systolic dipping percentage (Figure) and lower 24-hour average diastolic blood pressure obtained from the ABPM were both significantly associated with worse cognitive function. In the final model, each 1% less night-time dipping was associated with 0.25 points (0.1-0.9) lower MoCA score, whereas each 10 mmHg lower diastolic blood pressure was associated with 0.59 (0.14-1.05) points lower MoCA score. Conclusions: In community-living older persons, less nighttime systolic dipping and lower 24-hour diastolic blood pressure obtained by ABPM were associated with worse cognitive function whereas clinic based blood pressure measurements were not. Future studies should examine whether 24-hour diastolic blood pressure and nighttime systolic dipping may predict future risk for cognitive impairment.

Abstract Background To investigate blood pressure variability among 3 successive blood pressure measurements in an unselected nationwide population in China. Methods A total of 77,549 participants were included from measurements in May 2017 in China. Blood pressure was measured 3 times consecutively with a half minute interval. Blood pressure variability was estimated with the standard deviation and coefficient of variation of the systolic and diastolic blood pressure. Results Not all participants showed a decreasing trend with increasing number of measurements. In fact, 14% of the participants showed at least 5 mm Hg increase in systolic blood pressure. The coefficient of variation of systolic and diastolic blood pressure in women was higher than in men [(4.2 ± 3.3)% vs. (4.1 ± 3.3)%, (4.7 ± 4.0)% vs. (4.6 ± 4.1)%; P < 0.05]. The differences were significant (P < 0.01) among different groups of age and blood pressure levels. Multiple linear regression analysis showed that the systolic blood pressure variability indexes were inversely associated with age but positively associated with the level of the first systolic blood pressure reading (P < 0.01). The systolic blood pressure standard deviation and coefficient of variation in females were higher than in males (P < 0.01). Conclusions Not all subjects demonstrate a decreasing trend with increasing number of blood pressure measurements. Within-visit blood pressure variability varies with age, gender, and blood pressure.

Objective: This study evaluated the agreement of blood pressure measurements obtained through different auscultatory and oscillometric automated/semi-automated monitors. Material and Methods: The blood pressure of 30 participants was evaluated by a single calibrated examiner. The measurements were carried out through either auscultatory monitor (mercury column or aneroid) or automated/semiautomated oscillometric pulse monitors. For each participant, 5 min rest was established by sitting on dental chair and the measurements were always carried out on the left arm, at the heart level. Three consecutive measurements were performed with the four monitors in each participant with a minimum time interval of five minutes between each measurement. All monitors were properly calibrated and certified by INMETRO. The results were submitted to intraclass correlation coefficient and Friedman’s analysis of variance. Results: The measurements of systolic blood pressure for both auscultatory and oscillometric methods were similar. The measurements of diastolic blood pressure for auscultatory monitors were similar (p > 0.05); as well as for oscillometric monitors (p > 0.05). However, when auscultatory and oscillometric monitors were compared, there were statistically significant differences in diastolic blood pressure (p < 0.05). Conclusion: It was verified a difference in the results between the auscultatory and oscillometric blood pressure monitors. The systolic blood pressure measurements exhibited similar correlations, while diastolic blood pressure measurements showed different correlations.
