Objective: This study aimed to evaluate the accuracy of the ANDON KD-7920 oscillometric wrist blood pressure monitor in general population according to the ISO 81060-2:2018+AMD1:2020.

Methods: The same arm sequential method was used for blood pressure measurement among qualified participants according to the ISO 81060-2:2018+AMD1:2020. The validation results were assessed following the criteria of the protocol, and the Bland-Altman scatter plot was used to present the difference between the test device and reference results.

Results: A total of 90 participants were included in the study. According to criterion 1 of the validation protocol, the mean ± SD of the differences between the test device and reference readings was 0.76 ± 6.23 mmHg and -0.13 ± 5.57 mmHg for systolic and diastolic blood pressure, respectively, which met the requirements of less than 5 ± 8 mmHg. According to the criterion 2, the average differences between the test device and reference readings per participant were 0.76 ± 5.56 mmHg and -0.13 ± 5.27 mmHg for systolic and diastolic blood pressure, respectively, which also met the requirements.

Conclusion: The ANDON KD-7920 wrist blood pressure monitor passed all the requirements of the ISO 81060-2:2018+AMD1:2020 and can be recommended for clinical use and self-measurement in general population.

Background: Accurate measurement of blood pressure (BP) is crucial for the diagnosis and ongoing management of hypertension. Only devices that have been validated using an established protocol should be used to measure BP. The aim of this study was to validate the Microlife BP3T01-1B, an automated upper-arm BP measuring device, according to the DIN EN ISO 81060-2:2018-11 (ANSI/AAMI/ISO 81060-2:2018) standard protocol.

Methods: BP measurements were performed in 85 adults and adolescents (age range: 13-86 years) using the same-arm sequential method of the DIN EN ISO 81060-2:2018-11 protocol, alternating between the test device and a reference mercury sphygmomanometer.

Results: A total of 255 valid comparisons were available for the analysis of criterion 1. The mean ± SD difference between the test device and the reference device values was -2.56 ± 7.53 mmHg for SBP and -3.10 ± 5.65 mmHg for DBP. The mean differences met the pass criterion of less than or equal to ±5 mmHg and the SD values met the pass criterion of ≤8 mmHg. All 85 participants were included in the analysis of criterion 2. The mean ± SD intraindividual difference between the test and reference devices was -2.56 ± 6.15 mmHg for SBP and -3.10 ± 4.85 mmHg for DBP. Both were within the required pass range of SD ≤6.43 mmHg for SBP and SD ≤6.20 mmHg for DBP.

Conclusion: The Microlife BP3T01-1B BP monitoring device fulfilled the criteria of the DIN EN ISO 81060-2:2018-11 (ANSI/AAMI/ISO 81060-2:2018) protocol in a general population and can be recommended for the measurement of BP in adults and adolescents.

Background: Primary percutaneous coronary intervention (p-PCI) is pivotal in managing ST-segment elevation myocardial infarction (STEMI); however, it introduces potential risks, such as contrast-induced acute kidney injury (CI-AKI). This study aimed to investigate the relationship between pulse pressure (PP) and CI-AKI incidence in diabetic patients.

Methods: In this retrospective study conducted between 2021 and 2022, 590 diabetic STEMI patients undergoing p-PCI were categorized based on the presence of wide PP. Individuals with PP ≥ 65 mmHg were classified as the 'wide PP (+) group', while those with PP < 65 mmHg were classified as the 'wide PP (-) group'. To determine independent predictors of CI-AKI, multivariable logistic regression models were applied. After establishing the base model, blood pressure indices, including PP, SBP, DBP, mean arterial pressure, and pulsatility were added to the model using the stepwise selection method.

Results: Among the patients, 18.3% ( n  = 108) were in the wide PP (+) group, while 81.7% ( n  = 482) were in the wide PP (-) group. The incidence of hypertension, SBP, PP, and the risk of CI-AKI were higher in the wide PP (+) group. Multivariable analysis recognized PP, wide PP, and pulsatility as independent CI-AKI predictors [odds ratio (OR): 1.024, 95% confidence interval (CI): 1.003-1.045, P  = 0.025; OR: 1.684, 95% CI: 1.025-2.769, P  = 0.040; OR: 13.816, 95% CI: 2.069-92.245, P  = 0.007, respectively].

Conclusion: Increased PP emerges as an independent predictor for CI-AKI in diabetic patients undergoing p-PCI.

Objective: This study aimed to investigate the effects of power training (PT) using elastic bands combined with endurance training (ET) on pulse pressure (PP), systolic (SBP) and diastolic blood pressures (DBP), autonomic response (AR), and functional parameters in older adults.

Methods: Thirty participants were randomly assigned to the control group ( n  = 15) and the intervention group (IG) ( n  = 15). IG participants performed PT with elastic bands combined with ET twice weekly for 8 weeks. PP, SBP, DBP, AR, and functional parameters were assessed before and after 8 weeks.

Results: PP, SBP, and functional parameters significantly improved after 8 weeks in the IG ( P  < 0.05). The study also found a clinically significant reduction in the SBP (Δ = -16.5 mmHg; η2p  = 0.36) and DBP (Δ = -4.3 mmHg; η2p  = 0.26), and a clinical reduction in the 5-Repetition Sit-To-Stand test ( η2p  = 0.63) and the elbow flexion test ( η2p  = 0.51).

Conclusion: Our findings indicate that PT with elastic bands combined with ET improves PP, SBP, and functional parameters in older adults. Hence, our combined training protocol can be an easily accessible, low-cost, nonpharmacological strategy for strength, and conditioning professionals to prescribe as an exercise intervention to older adults.

Background: A possible chronic effect of exercise training is the attenuation of the acute decrease in blood pressure (BP) observed after the execution of a session of exercise [i.e. called postexercise hypotension (PEH)]. However, there are few empirical data regarding this issue, and the possible mechanisms involved in this blunted response have not been studied.

Aim: The study aimed to evaluate the effects of dynamic resistance training (DRT) on PEH and its systemic, vascular, and autonomic mechanisms.

Methods: Data from 16 middle-aged treated hypertensive men who underwent DRT (eight exercises, 50% of 1RM, three sets until moderate fatigue) three times/week for 10 weeks were analyzed. Before and after the training period, the participants underwent an experimental session in which BP (auscultation), systemic hemodynamics (CO 2 rebreathing), vascular function (duplex ultrasound), and cardiovascular autonomic modulation (spectral analysis of heart rate and BP variabilities) were assessed before and after a session of DRT.

Results: DRT reduced preexercise systolic BP and mitigated the systolic PEH that occurred before but not after the training period ( P  = 0.017). DRT did not change the diastolic PEH that occurred with similar magnitude before and after the training period ( P  = 0.024). DRT did not change the PEH mechanisms, except for cardiac sympathovagal balance that increased significantly more after the session of DRT conducted in the posttraining evaluation ( P  = 0.017).

Conclusion: In medicated hypertensive men, 10 weeks of DRT decreased preexercise systolic BP, abolished systolic PEH, and induced a greater increase in postdynamic resistance exercise sympathovagal balance.

Objective: Although it has long been established that age and sex play a role in blood pressure levels across the lifespan, the extent to which educational attainment moderates these relationships has been understudied. Thus, the purpose of this study was to assess educational differences in SBP, DBP, and pulse pressure (PP) trajectories among men and women through the midlife years.

Method: We conducted an analysis of pooled data from the 1999 to 2018 National Health and Nutrition Examination Survey to assess whether education moderates blood pressure measurements among men and women over the midlife years. Statistical analyses were performed using survey-weighted linear and quadratic regressions to assess these trajectories.

Results: During midlife, women with at least a college degree maintained the lowest average level of SBP compared to men at all education levels and women with a high school diploma or less. They also maintained the lowest level of PP, though not different from men with at least a college degree and women with less than a college degree. However, no educational differences were observed in DBP between men and women during the midlife years.

Conclusion: Our study shows clear delineation in the trajectories of PP and SBP by education such that a 4-year education is more protective than some college and a high school degree, particularly among women. These results highlight the need to consider upstream policy interventions (education policy initiatives) that could reduce population-wide elevated blood pressure.

Objective: Stress and working environments are risk factors for hypertension. A new occupational health policy called the Stress Check Program was started in Japan in 2015. Therefore, we clarified whether the presence or absence of high job stress (HJS) as determined using the Brief Job Stress Questionnaire (BJSQ) is related to the comorbidity of hypertension.

Methods: The results of a single year's BJSQ and medical examinations were investigated for 18 629 active Japanese male office workers who were 30-59 years old. The presence or absence of HJS was assessed using the BJSQ and investigated using a personal computer in a medical interview. Furthermore, the relationships between HJS and hypertension comorbidity were analyzed.

Results: The mean age of the subjects was 43.8 ± 10.3 years old, and the proportion of subjects with HJS was 10%. After adjustment for age and lifestyle habits, HJS was associated with a risk of hypertension comorbidity (odds ratio, 1.18; 95% confidence interval, 1.02-1.36; P = 0.022). HJS was a significant hypertensive comorbidity factor.

Conclusion: HJS measured using the BJSQ independently contributed to hypertension comorbidity among male office workers.

The impact of wearing a face mask for an extended duration is unknown. This study aimed to determine if wearing a face mask for 10 h impacts blood pressure (BP) and arterial stiffness. Subjects received an ambulatory blood pressure cuff and were asked to wear it for 10 h while readings were taken every 15 min. During the face mask trial, subjects wore an N95 mask for 10 h. During the control, subjects did not wear a mask. Subjects were randomized to start their trial. An accelerometer was given to ensure no physical activity differences. Linear mixed models were used to determine group differences, and McNemar test was used to assess frequency differences when determining BP load. Twelve college-aged (20.5 ± 1.5 years) male ( n  = 5) and female ( n  = 7) individuals with normal BP participated in this study. There were no differences in time spent in any physical activity domain (all P  > 0.05). There was no difference in brachial SBP ( P  = 0.688), brachial DBP ( P  = 0.063), central SBP ( P  = 0.875), central DBP ( P  = 0.246), heart rate ( P  = 0.125), and augmentation pressure ( P  = 0.158) between conditions. During mask condition, augmentation pressure was reduced by 5.2 ± 3.1% compared to control ( P  < 0.001). There were no frequency differences in the number of BP readings above 140 mmHg for SBP ( P  = 0.479) and >90 mmHg for DBP ( P  = 0.212). The current study found that wearing an N95 mask for 10 h did not affect brachial or central BP but significantly decreased augmentation pressure.

Objective: To validate the accuracy of the G.LAB MD6300 oscillometric upper arm blood pressure monitor in the sitting, supine, and right lateral decubitus position in the general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2 : 2018+AMD1 : 2020).

Methods: The qualified participants were recruited in the study and the same left-arm sequential method was used for blood pressure measurement according to the Universal Standard. The validation results were assessed for the three positions and the Bland-Altman scatter plot was used to show the difference between the test device and reference results.

Results: A total of 85 participants were included in the analysis. The mean differences between the test device and reference readings were 0.95 ± 6.76/0.47 ± 6.71 mmHg, 0.55 ± 6.73/-0.20 ± 6.72 mmHg, and - 0.71 ± 7.11/-0.86 ± 7.06 mmHg for SBP and DBP for the validation criterion 1 in the sitting position, supine with upward palm position, and right lateral decubitus position with downward left palm flat on left side position, respectively. Furthermore, the mean differences and their standard deviations for SBP and DBP calculated according to criterion 2 in the ISO81060-2 : 2018+AMD1 : 2020 were acceptable in all three positions.

Conclusion: The G.LAB MD6300 upper arm blood pressure monitor fulfilled the validation criteria of the AAMI/ESH/ISO Universal Standard (ISO 81060-2 : 2018+AMD1 : 2020) in the sitting position, and its accuracy in the supine and right lateral decubitus position was acceptable and roughly equivalent to that in the sitting position. Therefore, it can be recommended for clinical use and self-measurement in the general population.
