Blood Pressure Monitoring最新文献

Ambulatory blood pressure monitoring (ABPM) is recommended for confirming hypertension and assessing out-of-office blood pressure (BP). However, patient burden and device tolerability may limit broader implementation. We compared participant experience with a traditional oscillometric ABPM device and a compact cuff-integrated ABPM. The PRO-BP Study was a pilot randomized crossover study of 20 adults in New York City. Participants completed two 24-h ABPM periods over 7 days using the SpaceLabs 90227 and SOMNOmedics ABPMpro devices. After each period, participants rated comfort, pain, sleep interference, embarrassment, noise, skin irritation, and interference with daytime activities. Both devices achieved guideline-based recording-quality thresholds. Compared with SpaceLabs, ABPMpro was associated with greater comfort [median: 7.0 (interquartile range - IQR: 5.0-8.5) vs. 3.5 (IQR: 2.0-6.5); P = 0.026] and less pain [1.5 (0-3.5) vs. 5.0 (0.5-7.0); P = 0.022]. Other experience ratings did not differ significantly. Participant experience should be considered alongside recording quality when evaluating validated ambulatory BP monitoring technologies.

Objective: To evaluate the clinical accuracy of the AViTA BPM636 oscillometric upper-arm blood pressure monitor in the tested pediatric and adult population, including children aged 5-12 years and adults aged 21-82 years with arm circumferences ranging from 15 to 42 cm, according to the American National Standards Institute/Association for the Advancement of Medical Instrumentation/International Organization for Standardization (ANSI/AAMI/ISO) Universal Standard (ISO 81060-2:2018/Amd2:2024).

Methods: The AViTA BPM636 was evaluated in 85 participants (including 35 pediatric and 50 adult subjects) with upper-arm circumferences ranging from 15 to 42 cm, and two cuffs of different sizes (15 to 22 and 22 to 42 cm) were used in this study. The recruitment fulfilled the requirements of the ANSI/AAMI/ISO Universal Standard (ISO 81060-2:2018/Amd2:2024) for a combined pediatric and adult population using the same arm sequential blood pressure measurement method.

Results: For criterion 1, the mean ± SD of the differences between the test device and reference blood pressure measurements was 0.93 ± 6.11 mmHg for SBP and -0.20 ± 5.64 mmHg for DBP. For criterion 2, the SD of individual mean differences for SBP (5.44 mmHg) and DBP (4.98 mmHg) remained well within the maximum permissible limits of 6.88 and 6.95 mmHg, respectively, thereby satisfying the validation criteria.

Conclusion: The AViTA BPM636 passed the criteria of the ANSI/AAMI/ISO Universal Standard (ISO 81060-2:2018/Amd2:2024) protocol. It can be recommended for home-based blood pressure measurements in the tested population, including children aged 5-12 years and adults aged 21-82 years, with arm circumferences ranging from 15 to 42 cm.

To evaluate the overall effectiveness and safety of the ARM-30F-XL arm blood pressure (BP) monitor in individuals with an arm circumference of 22-52 cm. Subjects were recruited from patients, patient companions, and individuals attending routine health examinations at the hospital. The test device was the ARM-30F-XL, and the reference device was a mercury sphygmomanometer. Using BP readings obtained from the mercury sphygmomanometer as the reference standard, the accuracy of the noninvasive BP module of the test device was evaluated to determine whether it met the specified requirements. This study analyzed valid BP data from 97 subjects. According to criterion 1, the mean difference in SBP between the test device and the reference device was 1.69 mmHg, and the SD was 5.00 mmHg. The mean difference in DBP was -2.16 mmHg, and the SD was 4.45 mmHg. The mean difference of both SBP and DBP was less than ±5 mmHg, and the SD was less than 8 mmHg, which met the requirements. According to criterion 2, the SD of SBP was 4.00 mmHg, which was less than 6.73 mmHg and met the requirements. The SD of DBP was 3.73 mmHg, which was less than 6.58 mmHg and met the requirements. The ARM-30F-XL complies completely with International Standard ISO 81060-2:2018+Amd 2:2024 and is recommended for BP measurement in individuals with an arm circumference of 22-52 cm for home and clinical use.

Background: Multimorbidity represents significant public health challenges, particularly in postmenopausal women, who experience increased risks for cardiovascular and metabolic diseases because of hormonal changes. While exercise therapy has shown promise in enhancing health outcomes for individuals with multimorbidity, evidence of its effectiveness in this specific population remains limited.

Objective: This study investigated the effects of a 12-week aerobic training program on ambulatory blood pressure, blood pressure variability, and arterial stiffness in postmenopausal women with and without cardiometabolic multimorbidity.

Methods: A controlled, quasi-experimental study was conducted with 41 women divided into two groups: SINGLE (one cardiometabolic condition; n  = 18) and MULTI (multimorbidity; n  = 23). Participants underwent aerobic training three times a week. Ambulatory blood pressure, blood pressure variability, and arterial stiffness were assessed before and after the intervention.

Results: A significant reduction in diastolic nocturnal dipping was observed only in the MULTI group (interaction P  = 0.019), decreasing from 10 ± 12% to 7 ± 9%. Both groups showed a significant reduction in systolic (SINGLE: 21 to 8; MULTI: 19 to 7) and diastolic morning surge (SINGLE: 16 to 11; MULTI: 16 to 6) (time P  < 0.001). No interaction effect was observed in arterial stiffness parameters. An exercise intervention effect ( P  = 0.001) indicated an increase in augmentation index (%) in both groups following aerobic training.

Conclusion: A 12-week aerobic program improved morning surge blood pressure in postmenopausal women. However, the MULTI group showed reduced nocturnal dipping.

The aim of the study was to determine the accuracy of the Prolife PX7 Premium monitor for upper arm blood pressure (BP) measurement according to the International Organization for Standardization (ISO) 81060-2:2018/Amd1:2020/Amd2:2024 protocol. The Prolife PX7 Premium device, an oscillometric fully automatic BP monitor designed for BP measurement by both healthcare professionals and home users, is provided with a single wide-range conical cuff suitable for arm circumferences ranging from 22 to 45 cm. The device was tested in 86 subjects from the general population (52.3% men) with a mean age of 43.2 years. The mean device-observer systolic and diastolic BP differences and their SDs were in agreement with criterion 1 of the protocol requirements (≤5 ± 8 mmHg), being 4.3 ± 4.4 and 3.4 ± 4.3 mmHg, respectively. The measurement errors were unrelated to the arm sizes. Also, criterion 2 of the ISO 81060-2:2018/Amd1:2020/Amd2:2024 protocol was satisfied. The SDs of systolic and diastolic BPs were 4.2 and 4.1 mmHg, respectively, well below the maximum values required by the protocol (5.49 and 5.56 mmHg for systolic and diastolic BPs, respectively). The present results show that the Prolife PX7 Premium monitor satisfied the requirements of the ISO 81060-2:2018/Amd1:2020/Amd2:2024 protocol for the general population, demonstrating that a single cuff designed for a wide range of arm sizes can provide reliable measurements across a 22-45 cm range of arm circumferences.

Guidelines recommend initial blood pressure assessment on both arms, with the higher-reading arm used for future measurements. As simultaneous measurement devices are often unavailable, we evaluated if sequential measurements are appropriate for assessing interarm differences. Blood pressure was measured in Shanghai using an automated system. Consecutive readings were taken with 1-min intervals, beginning with the right followed by the left arm, with a third reading if the difference between the first two exceeded 5 mmHg. In 7838 participants, right arm readings were consistently higher, with mean interarm systolic/diastolic differences of 4.59/1.01 mmHg if two readings on each arm, 6.24/1.45 mmHg if two readings on one and three readings on another arm, and 7.22/1.90 mmHg if three readings on each arm. This sequential measurement approach led to more frequent right arm selection for blood pressure measurement and potential overestimation of the interarm differences. Simultaneous measurements may be needed, but future studies are required to confirm this.

Background: Overt policing is a stressful occupational duty that burdens the cardiovascular system. Individuals with high blood pressure (BP) have been shown to have exacerbated cardiovascular reactivity to mental stress tests. However, it is unknown whether this premise is the same for policemen.

Aim: To assess whether police officers with higher baseline BP exhibit exacerbated cardiovascular reactivity to mental stress.

Method: Forty-one policemen (34 ± 4 years) were divided into two groups: lower BP (SBP < 120 mmHg, n  = 15) and higher BP (SBP ≥ 120 mmHg, n  = 26). The policemen were also subjected to acute mental stress. Cardiovascular reactivity was assessed at 2- and 4-min, while cardiovascular recovery was analyzed at 3 and 5 min.

Results: Policemen with higher baseline BP showed higher SBP values ( P  < 0.001) at 2 min (148 ± 12 vs. 128 ± 13 mmHg) and 4 min (140 ± 10 vs. 125 ± 9 mmHg) of the acute mental stress, compared with policemen with lower baseline BP. During recovery, policemen with higher BP showed higher SBP values ( P  < 0.001) at 3 min (130 ± 10 vs. 120 ± 7 mmHg) and 5 min (129 ± 8 vs. 116 ± 8 mmHg) compared with policemen with lower BP. DPB was higher ( P  = 0.005) in policemen with higher BP compared with the policemen with lower BP, regardless of time. There was no difference in heart rate response between groups ( P  > 0.005).

Conclusion: Policemen with a higher baseline BP exhibited greater cardiovascular responses during acute mental stress.

Background: Hypertensive disorders of pregnancy remain a leading cause of maternal and fetal morbidity and mortality worldwide. In women with chronic hypertension, adequate 24-h ambulatory blood pressure (ABPM) control has been associated with a reduced risk of adverse outcomes, including preeclampsia. However, the ability of office blood pressure (BP) measurements to reliably identify women with controlled ABPM during pregnancy remains uncertain. We conducted a retrospective cohort study including pregnant women with chronic hypertension evaluated before 20 weeks of gestation at a high-risk pregnancy center.

Methods: Office BP and 24-h ABPM were assessed using a standardized protocol at three gestational periods (14, 20, and 30 weeks). Controlled ABPM was defined by 24-h, daytime, and nighttime BP thresholds. Receiver operating characteristic curve analyses were performed to evaluate the discriminative ability of office systolic and diastolic BP to identify controlled ABPM and to explore potential cut-off values.

Results: Among 247 women with chronic hypertension, office BP demonstrated limited discriminatory performance across all gestational stages. Area under the curve values were consistently close to or below 0.5 for both systolic and diastolic BP, indicating poor classification ability. Cutoff values identified using the Youden index were clinically implausible and would have classified only a minimal proportion of women as having controlled ABPM. Even when clinically intuitive office BP thresholds were applied, sensitivity and specificity remained low. These findings indicate that office BP measurements cannot be considered a reliable surrogate for ABPM control in pregnant women with chronic hypertension.

Conclusion: Consequently, ABPM remains essential for accurate BP assessment and risk stratification, particularly during the second half of pregnancy.

Objective: This study aimed to evaluate the accuracy of the Wellvii BP Go automated oscillometric finger blood pressure (BP) monitor for self/home BP measurement according to the International Standardization Organization (ISO) 81060-2 : 2018.

Methods: A total of 85 eligible participants was included in the study to fulfill the age, sex, and BP distribution criteria of the ISO standard in the general population. The same arm/finger sequential measurement method was used for comparison with a standard mercury sphygmomanometer, and the assessment were in accordance with the ISO 81060-2 : 2018 protocol.

Results: A total of 255 comparison pairs were obtained for analysis. For validation Criterion 1, the mean ± SD of the differences between the test device and reference systolic BP/diastolic BP readings was 2.12 ± 7.33 and 1.30 ± 6.35 mmHg. For validation Criterion 2, the SD of the averaged systolic BP/diastolic BP differences between the test device and reference BP per participant was 6.58/5.60 mmHg, respectively.

Conclusion: The Wellvii BP Go automated finger BP monitor has passed the requirements of the ISO 81060-2 : 2018, and can be recommended for self/home BP measurement in general population.

Objectives: To investigate the association between long-term predialysis blood pressure (BP) change and all-cause mortality in patients on maintenance hemodialysis (MHD).

Methods: We retrospectively included patients receiving MHD from 1 January 2019 to 31 December 2024. The regression slope was used to estimate BP temporal change with dialysis vintage. The regression slope was divided into three groups: small slope (absolute number < 0.05), large increasing slope (≥ 0.05 group), and large decreasing slope (≤-0.05 group). If the regression slope was positive, we defined the trend of BP was increasing. Conversely, BP showed a decreasing trend. Survival analysis was performed using Cox proportional hazards regression models.

Results: A total of 812 patients with 317 894 predialysis BP measurements were included in the final cohort. The mean predialysis BP was 146.44/85.66 mmHg. During the study period, 161 deaths occurred. In multivariable Cox regression analysis, patients with a small slope of SBP or DBP demonstrated the highest survival rate. Both patients with a large increasing slope or a large decreasing slope had significantly higher mortality ( P  < 0.001). Notably, a BP change direction (an increasing or decreasing trend) was not associated with mortality. The association between long-term predialysis BP slope and mortality was independent of age at first hemodialysis, diabetic nephropathy, coronary heart disease, pulse rate, antihypertensive drug, and ultrafiltration. This association was consistent for both SBP and DBP.

Conclusion: A stable trend of long-term predialysis BP was associated with a favorable survival outcome. Both SBP and DBP influence clinical outcomes.
