Morning blood pressure surge (MBPS) has been recognized as an independent predictor of cardiovascular disease events. Psychological distress, including anxiety, depression, and perceived stress, and behavioral risk factors, such as poor sleep quality, have been associated with increased MBPS. Elevations in sympathetic activity induced by forced awakening may also contribute to further increases in MBPS. Yet, no examination of the interrelationships among psychological distress, sleep quality, awakening mode (natural vs. forced awakenings), and MBPS has been undertaken.

Atrial fibrillation (AF) is a stroke and heart complication risk but is often overlooked due to subtle symptoms. The accessibility of sphygmomanometers that can detect AF, may play crucial roles in identifying asymptomatic patients. AViTA BPM63B is an automatic blood pressure (BP) monitor for atrial fibrillation detection. This study validated the performance of BPM63B for AF detection using two novel algorithms of time-domain analysis and frequency-domain analysis which evaluate multiple statistics.

Evaluation of the accuracy of the wrist-type fully automatic blood pressure (BP) monitor: DBP-2242 in adolescent and adult populations according to ISO 81060-2 : 2018+Amd.1 : 2020.

ST2 receptor is a member of toll-like/interleukin-1 receptor family. After the activation of IL-33/ST2 signaling pathway clinically detectable amount of soluble form of ST2 (sST2) is released into the circulation. Previous studies showed that sST2 levels were significantly higher in hypertension patients than in controls. In this prospective study, we aimed to analyze this relation and test the predictive accuracy of the sST2 level in diagnosis of nondipping hypertension in newly diagnosed hypertension patients.

Since hyperuricemia is a risk factor for cardiovascular disease and chronic kidney disease, it is necessary to pay attention to trends in uric acid levels when treating hypertensive patients with drugs. The present study investigated the effect of switching from angiotensin II receptor blocker (ARB) to sacubitril/valsartan on serum uric acid levels in treated hypertensive patients and further examined what factors could be associated with its effect.

To determine the accuracy of the AViTA BP636 upper-arm home blood pressure (BP) monitor in general populations with small to extra-large arms according to the ANSI/AAMI/ISO Universal Standard (ISO 81060-2 : 2018/Amd1 : 2020).

Remote patient monitoring (RPM) beat-to-beat blood pressure (BP) provides an opportunity to measure poststroke BP variability (BPV), which is associated with clinical stroke outcomes. BP sampling interval (SI) influences ambulatory BPV, but RPM BP SI optimisation research is limited. SI and RPM device capabilities require compromises, meaning SI impact requires investigation. Therefore, this study assessed healthy and stroke subtype BPV via optimised BP sampling, aiding sudden BP change identification and potentially assisting cardiovascular event (recurrent stroke) prediction.

Ambulatory blood pressure monitoring (ABPM) requires automatic measurement and the use of a validated device, according to current guidelines and international standardization. The TM-2441 (A&D Co. Ltd, Tokyo, Japan) ABPM device is small, lightweight, and suitable for use in ambulatory settings. It was validated against the ISO 81060-2:2013 standard in the general population. This study investigated the reliability of the ABPM device for patients with type 2 diabetes.

This study evaluated the accuracy of blood pressure measurement in adults using FF680 electronic blood pressure monitors with the Korotkoff-Sound method, in accordance with the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) universal standards (ISO 81060-2 : 2018). The study was conducted at Shijiazhuang People's Hospital and lasted 56 days, from May 26 to 21 July 2023. Participants, drawn from an adult demographic, underwent data verification and analysis with strict adherence to the trial protocol. For the FF680 electronic blood pressure monitor using the Korotkoff-Sound method, data from 85 valid participants were analyzed. The findings revealed mean differences (standard deviations) of -0.66 mmHg (2.45 mmHg) for SBP and -0.28 mmHg (2.09 mmHg) for DBP. SBP and DBP had standard deviations of ≤6.9 mmHg and ≤6.95 mmHg, meeting the standard requirements. FF680 devices are recommended for adult blood pressure monitoring because they meet the AAMI/ESH/ISO universal requirements (ISO 81060-2 : 2018).

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.

This study aimed to validate the accuracy of the test device (TMB-2296-BT) blood pressure (BP) monitor in adults according to International Standard Organization (ISO) 81060-2:2018 + Amd.1:2020 universal standard protocol, which is a digital monitor. Three trained observers used the same arm sequential method to compare the SBPs and DBPs measured by the test device with those measured by the reference device (mercury sphygmomanometer). For the test device with cuff ranging from 22 to 32 cm, there are 88 adults, with a male-to-female ratio of 35 : 53. The mean difference and SD between reference BPs and test device BPs readings were (0.21 ± 2.59)/(0.66 ± 2.12) mmHg for SBP/DBP for criterion 1, and (0.21 ± 2.07)/(0.66 ± 1.76) mmHg for SBP/DBP for criterion 2. For the test device with cuffs ranging from 22 to 42 cm, there are 87 adults, with a male-to-female ratio of 49 : 38.

And for the test device with cuff arm circumference sizes of 22-32 cm and 22-42 cm fulfilled both validation criterion 1 and 2 of the ISO 81060-2:2018 + Amd.1:2020 standard and can be recommended for both clinical and self/home BP measurement in adults.

Cardiovascular events are positively associated with primary hypertension (HTN), obesity, and low cardiorespiratory fitness (CRF) and negatively with healthy dietary patterns, such as Healthy Diet Indicator (HDI), Mediterranean diet (MD), and the Dietary Approaches to Stop Hypertension (DASH). The aim is to analyze the association between healthy dietary patterns with body composition and CRF. Body composition (bioimpedance) and CRF [peak oxygen uptake (V̇O2peak)] were assessed in 165 participants with HTN and overweight/obesity. There were (1) a positive association (unadjusted) between fat-free mass (%) with DASH and MD (P = 0.03) and a negative association between fat mass (%) and MD (P = 0.03); (2) positive associations (adjusted) between V̇O2peak (l·min-1) with DASH (P = 0.007), HDI (P = 0.017), and MD (P = 0.010) and V̇O2peak (ml·kg-1·min-1) with DASH (P = 0.005); (3) a negative relationship (unadjusted and adjusted) between energy intake and DASH (P = 0.004). In conclusion, these findings highlight the cardiovascular health protection provided by healthy dietary patterns associated with healthier CRF and body composition in people with a profile of HTN and overweight.

To determine the independent effect of high-sensitivity C-reactive protein (hs-CRP) and the combined effects of hs-CRP and other traditional risk factors on microalbuminuria in hypertensive patients during the 3-year follow-up period.

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.

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.

This study aims to compare the differences between unattended and conventional blood pressure measurements in hospitalized hypertensive patients.
