Blood Pressure Monitoring最新文献

Objective: Cardiovascular disease (CVD) is the leading global cause of death, with elevated blood pressure (BP) in young adults being linked to CVD in adulthood. Pulse wave velocity (PWV) is a noninvasive measure of arterial stiffness, a predictor of CVD, and can be influenced by exercise. Exercise, like stair climbing, improves vascular health and reduces BP. The primary aims of this study were to examine whether the change in BP after a single stair climb is associated with PWV and whether it is associated with 24-h BP averages.

Methods: Fifty-four young adults (23.8 ± 3.56 years) underwent back-to-back sessions of vascular health assessment, a 24-h ambulatory BP (ABP) monitoring, and a single stair climb exercise consisting of 42 steps. Pre- to post-climb BP response was calculated.

Results: Our population was normotensive (119.4/73.7 mmHg) and had an increase in SBP (126.4-138.5 mmHg, P < 0.05) and heart rate (HR) (85.6-94.2 bpm, P < 0.05) with climb. We found an inverse relationship between PWV (5.4 ± 0.85 m/s) and change in SBP with climb (r = -0.340, P = 0.012). We found no relationship between 24-h BP averages and post-stair climb response.

Conclusion: The first to report an inverse relationship between SBP response to exercise and PWV in young adults emphasizes subtle differences in vascular compliance. While the stair climb elicited a significant vascular response, there was no association with 24-h ABP averages. The potential of stair climbing as a practical exercise for assessing vascular health underscores the need for future research.

Objectives: Nocturnal hypertension, especially with well-controlled daytime blood pressure (BP), has emerged as a significant risk factor for cardiovascular disease. This study investigated its prevalence by morning home BP cut-off values and examined associated patient characteristics using data from the Japan Morning Surge-Home Blood Pressure (J-HOP) study.

Methods: This post hoc analysis included 2675 participants from the J-HOP study who had complete data on nighttime home BP, measured using validated automatic oscillometric devices. Nocturnal hypertension was defined as a nighttime systolic BP greater than or equal to 120 mmHg and diastolic BP greater than or equal to 70 mmHg.

Results: Among the participants, 60.5% had nocturnal hypertension. The proportion of patients with nocturnal hypertension decreased as the cut-off value for morning home BP was lowered: 40.5, 32.1, 23.7, and 14.6% for less than 135/85 mmHg, less than 130/80 mmHg, less than 125/75 mmHg, and less than 120/70 mmHg, respectively. The prevalence of nocturnal hypertension was significantly higher in individuals with diabetes compared with those without, at morning home BP thresholds of less than 135/85 mmHg (48.1 vs. 39.3%; P = 0.03) and less than 130/80 mmHg (41.0 vs. 30.6%; P = 0.01). Individuals taking diuretics had a significantly lower prevalence of nocturnal hypertension compared with those not taking diuretics, at a morning home BP threshold of less than 135/85 mmHg (35.3 vs. 42.9%; P = 0.01).

Conclusion: A considerable number of patients continued to show nocturnal hypertension even at lower morning home BP thresholds. Diabetes may contribute to nocturnal hypertension despite well-controlled morning BP, while diuretic use may help prevent it.

Objectives: To evaluate 24-h ambulatory systolic blood pressure (BP), diastolic BP, and pulse rate patterns in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI), and their association with major adverse cardiac events (MACE).

Methods: We conducted a prospective cohort study in ACS patients in who ambulatory BP monitoring was recorded during 2 weeks post-PCI. Clinical and laboratory factors correlated with dipping BP and pulse rate were analyzed by multivariable logistic regression analysis. A Cox proportional hazard model was applied to find the associated factor(s) with their MACE.

Results: We included 141 patients with ST-elevation myocardial infarction (STEMI) ( n  = 47) and non-STEMI ( n  = 94). The average age was 61.7 ± 11.1 years. Most of them are men (63.8%), had non-STEMI (66.7%), and triple vessel disease (51.1%). Upon assessment of nocturnal dipping BP, 22% were dippers, while the others were nondippers and reverse dippers (39.7 and 38.3%, respectively). Nocturnal hypertension, neutrophil-to-lymphocyte, and mean platelet volume were significantly associated with nondippers [adjusted odds ratio: 5.71, 95% confidence interval (CI): 2.51-12.99; 1.29, 95% CI: 1.01-1.63; 1.84, 95% CI: 1.16-2.93, respectively]. Nondipping pulse rate was found in 66.0% with a mean pulse rate of 75.4 ± 10.9 beats per minute (bpm) (awake) and 70.0 ± 11.2 bpm (sleep). Nondipping pulse rate was only found as an independent factor associated with MACE (hazard ratio: 2.69, 95% CI: 1.06-6.86, P  = 0.04).

Conclusion: This study demonstrated a significant association of MACE with nondipping pulse rate in patients with ACS who underwent PCI.

Background: Isometric exercise has emerged as an effective strategy for blood pressure (BP) management, offering potential advantages over traditional exercise modalities; however, evidence regarding its 24-h effects in medicated hypertensive postmenopausal women remains limited.

Objective: This study investigated the effects of a single session of multijoint isometric exercise on 24-h ambulatory hemodynamic variables in medicated hypertensive postmenopausal women.

Methods: In this randomized crossover trial, 10 medicated hypertensive postmenopausal women (59 7 years) completed two experimental sessions: an isometric exercise session and a control session. The isometric exercise consisted of six multijoint exercises (upper and lower limbs), each performed for three sets of 1 min at 30% of 1-repetition maximum, with 2-min rest intervals. The control session involved sitting at rest for an equivalent duration. Following each session, 24-h ambulatory BP monitoring was conducted.

Results: Significant systolic BP reductions were observed following the isometric exercise session compared with the control session at 1 h (P < 0.05), 6 h (P < 0.05), and 24 h (P < 0.05). Diastolic BP was also reduced at 1 h (P < 0.05) and 12 h (P < 0.05). Both awake and asleep periods showed significant BP reductions for systolic and diastolic BP (all, P < 0.05).

Conclusion: A single session of multijoint isometric exercise effectively reduces ambulatory BP over a 24-h period in medicated hypertensive postmenopausal women, including both awake and asleep periods. These findings support the potential clinical utility of isometric exercise as an adjunctive strategy for BP management in this population.

Background: This study aimed to validate the accuracy of the YuWell YE990 automated oscillometric upper-arm blood pressure (BP) monitor in pregnant adults according to the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization Common Criteria Universal Standard (ISO 81060-2:2018 + Amd.1:2020).

Methods: Participants with normotension, hypertension without proteinuria, or pre-eclampsia were enrolled in this study. BP measurements were performed using a calibrated mercury sphygmomanometer (reference) and a YE990 device (test) following a same-arm sequential protocol conducted by two trained observers.

Results: A total of 46 participants (138 paired readings) were included in the final analysis. For criterion 1 of the standard, the mean difference between the test and reference devices was -2.9 ± 6.9 mmHg for systolic BP (SBP) and 0.0 ± 6.5 mmHg for diastolic BP (DBP), both within the required limits. For criterion 2, the subject-level SDs were 5.6 mmHg for SBP and 5.7 mmHg for DBP, also satisfying the ISO thresholds of 6.30 and 6.95 mmHg, respectively.

Conclusion: YuWell YE990 met all accuracy criteria specified by the ISO 81060-2:2018 + Amd.1:2020 standard and is recommended for clinical use in pregnant populations.

Aim: To examine the effect of excess body weight on the blood pressure (BP) of children aged 6-12 years.

Methods: This was a prospective longitudinal study conducted with 187 children at the participants' home in southern Brazil. BP was measured using the auscultatory method. Generalized linear mixed models, including fixed and random effects and adjusted for important covariates, were used to estimate the relative risk (RR) of excess body weight on the incidence of high BP in children throughout the three follow-ups of the study (at ages 6, 9, and 12 years).

Results: The prevalence of high BP increased from 25.0 to 66.7% in children with excess body weight from 6 to 12 years of age. For every 1 kg/m2 increase in the child's BMI, there was an 8% increase (RR = 1.08, 95% confidence interval: 1.00-1.16, P = 0.042) in the risk of the child having high BP from 6 to 12 years of age, even after adjusting for prepregnancy BMI.

Conclusion: Excessive BMI in children increased the risk of high BP in Brazilian children from 6 to 12 years of age. Special attention must be paid to children under 12 years of age with excess body weight to mitigate the onset of cardiovascular diseases throughout life.

We aimed to evaluate the accuracy of B.Well PRO-33 (B.Well, Widnau, Switzerland) oscillometric device for professional office measurement of blood pressure (BP) on the upper arm in the general population in accordance with the Amendment 2.2024-01 of the Standard 81060-2:2018 by the International Organization for Standardization (ISO 81060-2:2018/AMD 2:2024). Study participants were recruited according to the age, gender, BP, and cuff distribution requirements of the ISO 81060-2:2018/AMD 2:2024 in the general population using the sequential BP measurement method on the same arm. The test device was used with one universal cuff for arm circumferences of 22-42 cm. We chose aneroid sphygmomanometers Riester Big Ben Square Desk (Rudolf Riester, Jungingen, Germany) with small, medium and large cuffs and Welch Allyn 767 Desk (Welch Allyn, Skaneateles Falls, NY, USA) with a large adult cuff for arm circumferences of 22-37 and 38-42 cm, respectively, as control devices. We enrolled 112 study subjects, of whom 85 were analyzed. For validation criterion 1, the mean ± SD of the differences between the readings of the tested device and reference BP (systolic/diastolic; threshold ≤5 ± 8 mmHg; N = 255) was 1.7 ± 5.4/1.8 ± 5.7 mmHg. For validation criterion 2, the SD of the mean BP difference between the tested device and reference BP readings per subject (systolic/diastolic; threshold ≤ 6.73/6.71 mmHg; N = 85) was 4.7/4.7 mmHg. B.Well PRO-33 professional office BP monitor met the requirements of the ISO 81060-2:2018/AMD 2:2024 for the general population, and therefore can be recommended for clinical use.

Objective: Arterial hypertension is a major global cause of cardiovascular disease, a risk heightened by postmenopausal physiological changes. Although aerobic exercise is protective, its optimal intensity, duration, and supervision for hypertensive postmenopausal women remain unclear. This study, therefore, compares a supervised intensive aerobic program with a home-based regimen, assessing their effects on key cardiac health indicators in this population.

Methods: In this single-center pilot randomized controlled trial, we enrolled 31 postmenopausal women. Participants were divided into two groups: one underwent a 6-week supervised intensive aerobic exercise program, and the other followed a home-based exercise regimen. Key outcome measures included cardiorespiratory endurance, heart rate variability, and blood pressure variability. Outcome measures were evaluated at weeks 6 and 12. Intra-group and inter-group comparisons were evaluated using appropriate statistical methods.

Results: After 12 weeks, the supervised exercise group showed significant improvements in VO2max (P = 0.003), metabolic equivalents (METs) (P = 0.002), and standard deviation of normal-to-normal intervals (SDNN) values (P = 0.034) at both the 6th and 12th weeks. However, the sole significant inter-group difference was a greater reduction in 24-hour SBP variability (SBP-SD) in the supervised arm (Δ -0.95 ± 1.15 vs. + 1.54 ± 0.94 mmHg; P = 0.041), driven mainly by the week 6-12 interval (P = 0.004).

Conclusion: Supervised intensive aerobic exercise produced clear within-group gains in VO₂ max, METs, and SDNN, and it reduced 24-hour SBP variability relative to home-based walking. Although between-group differences for the primary fitness and autonomic outcomes were not statistically significant in this pilot, the pattern suggests that a supervised, tailored program may confer additional clinical benefit and merits evaluation in a larger trial.

This study aimed to assess the accuracy of the CONTEC08C automated oscillometric upper-arm sphygmomanometer in adults for clinical use in accordance with the ISO 81060-2:2018 standard. A total of 90 normotensive and hypertensive participants aged 18-75 years were recruited, and 85 were analyzed to evaluate the accuracy of the CONTEC08C oscillometric upper-arm sphygmomanometer using the same arm sequential validation method and a standardized protocol. The mean ± standard deviation (SD) of the differences between the test device and reference blood pressure (BP) measurements was 0.5 ± 3 mmHg for SBP and 0.4 ± 3.5 mmHg for DBP, meeting validation criterion 1. For validation criterion 2, the SD of the averaged differences between the test device and reference BP measurements per subject was 1.81/2.41 mmHg (systolic/diastolic). The CONTEC08C oscillometric upper-arm blood pressure monitor fulfilled the requirements of the ISO 81060-2:2018 standard in adults in the clinical setting and can therefore be recommended for safe clinical use.

Objective: This study aims to evaluate the accuracy of the Omron HBP-1320 electronic blood pressure (BP) monitor for ambulatory BP measurement in both pediatric and adult populations according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) (ISO 81060-2:2018/Amd 1:2020) protocol.

Methods: Subjects who met age, gender, BP, and cuff distribution criteria specified by the AAMI/ESH/ISO (ISO 81060-2:2018/Amd1:2020) protocol were recruited for this study. BP measurements were performed using the same-arm sequential measurement method. The test device was equipped with cuffs suitable for arm circumferences ranging from 12.0 to 42.0 cm.

Results: A total of 87 participants were initially recruited, with 85 (35 children and 50 adults) included in the final analysis after excluding two participants. The mean age of all participants was 38.1 ± 28.98 years, with children averaging 6.7 ± 2.23 years and adults 60.1 ± 15.39 years. For validation criterion 1, the mean ± SD of differences between the test device and reference BP measurements was 2.3 ± 5.47 mmHg for SBP and 1.3 ± 5.65 mmHg for DBP. Both mean differences were ≤5 mmHg, and SDs ≤ 8 mmHg, meeting the criterion. For validation criterion 2, the mean differences were 2.3 ± 3.93 mmHg for SBP and 1.3 ± 5.13 mmHg for DBP, satisfying the thresholds of ≤6.55 mmHg for SBP and ≤6.82 mmHg for DBP.

Conclusion: The Omron HBP-1320 electronic BP monitor meets the requirements of the AAMI/ESH/ISO (ISO 81060-2:2018/Amd 1:2020) validation standard for adults and children.
