RESUMO
CONTEXT: Disparities in cardiovascular disease prevalence and death exist among South Carolina's rural residents. Blood pressure self-monitoring (BPSM), where individuals measure their own blood pressure outside of the clinical environment, coupled with additional support, is an evidence-based, cost-effective strategy that is underutilized at large. PROGRAM: The YMCA's BPSM program is an evidence-based, 4-month program that includes 2 individualized office hours with a Healthy Heart Ambassador and 4 nutrition education sessions per month. Participants are provided with a blood pressure cuff and notebook to track their blood pressure at home in between sessions. IMPLEMENTATION: The SC Department of Health and Environmental Control partnered with the SC Alliance of YMCAs to expand the YMCA's BPSM program virtually. The traditional program was adapted to allow for virtual participant encounters. To target rural communities, partnerships were leveraged or established with rural health centers, federally qualified health centers, free medical clinics, and other state health department regions for participant referrals into the program. EVALUATION: A developmental evaluation design was utilized to monitor the virtual adaptation of the YMCA's BPSM program from April 2021 to May 2023. At the end of the project, 10 referral sources were identified to refer participants to the program. In total, 253 participants were referred to the program, 126 participants enrolled into the program, and 52 participants completed the program. Completers of the virtual program were successful in improving their blood pressure. DISCUSSION: Successes of the virtual program were not without challenges. Lessons learned from the virtual expansion of this program included ensuring participants' readiness to engage in a 4-month program, assessing participants' digital literacy, and considering broadband access in rural areas. Improvements in blood pressure and the program's reach demonstrate merit in continuing to scale the virtual adaptation of this program; however, contextual and structural factors should be considered.

Continuous blood pressure (BP) tracking provides valuable insights into the health condition and functionality of the heart, arteries, and overall circulatory system of humans. The rapid development in flexible and wearable electronics has significantly accelerated the advancement of wearable BP monitoring technologies. However, several persistent challenges, including limited sensing capabilities and stability of flexible sensors, poor interfacial stability between sensors and skin, and low accuracy in BP estimation, have hindered the progress in wearable BP monitoring. To address these challenges, comprehensive innovations in materials design, device development, system optimization, and modeling have been pursued to improve the overall performance of wearable BP monitoring systems. In this review, we highlight the latest advancements in flexible and wearable systems toward continuous noninvasive BP tracking with a primary focus on materials development, device design, system integration, and theoretical algorithms. Existing challenges, potential solutions, and further research directions are also discussed to provide theoretical and technical guidance for the development of future wearable systems in continuous ambulatory BP measurement with enhanced sensing capability, robustness, and long-term accuracy.

OBJECTIVE: Ambulatory blood pressure monitoring (ABPM) devices play a crucial role in diagnosing hypertension, not only in adults but also in pediatric patients. ABPM-06, the latest oscillometric device from Meditech Ltd. (Budapest, Hungary), is the focus of this study. The objective was to validate the ABPM-06 device using the International Organization for Standardization (ISO) 81060-2â :â 2018 standard. METHODS: A total of 86 healthy patients, consisting of 34 males and 52 females, aged between 3 and 17 years, were enrolled in this study. During the ambulatory phase, a total of 50 patients were enrolled, with 35 patients falling within the 3- to 12-year-old age range and 15 patients aged between 12 and 17 years. Additionally, for the dynamic test, 36 patients were selected, comprising of 10 individuals aged 3-12 years and 26 patients aged 12-17 years. These patients were recruited from the outpatient clinics of the Department of Pediatrics at Albert Szent-Györgyi University in Szeged, Hungary. The validation process involved utilizing the same-arm sequence protocol, both in resting positions and during stress testing. RESULTS: The ABPM-06 performed well in both clinical and ambulatory validations. In terms of validation criterion 1, the mean ± SD of the differences between the test device and reference blood pressure readings was -1.3â ±â 3.5 â mmHg for systolic and -0.1 â ±â 2.3 mmHg for diastolic, in children under the age of 12 years. For those over the age of 12 years, the mean ± SD of the differences was -2.8 ± 4.6 mmHg for systolic and -0.5 ± 2.7 mmHg for diastolic. Regarding the ambulatory validation, for children under 12 years old, the mean ± SD of the differences was -1.3 â ±â 3.5 â mmHg for systolic and -0.1 â ±â 2.3 â mmHg for diastolic. In the age group above 12 years, the mean ± SD of the differences was -2.8 ± 4.6 mmHg for systolic and -0.5 ± 2.7 mmHg for diastolic. Both tests successfully met the established criteria regarding the mean and SD values of the differences between the device readings and the observed SBP and DBP measurements. CONCLUSION: The ABPM-06 oscillometric device fully adheres to the ISO 81060-2â :â 2018 standard requirements for ABPM determination in the pediatric population (ages 3-17 years). Consequently, this ABPM device proves to be suitable for effectively managing hypertension in children and adolescents.

The nocturnal blood pressure (BP) surge in seconds (sec-surge) is defined as a brief, acute transient BP elevation over several tens of seconds, triggered by obstructive sleep apnea (OSA) and sympathetic hyperactivity. Sec-surge imposes a significant strain on the cardiovascular system, potentially triggering cardiovascular events. Quantitative evaluation of sec-surge level could be valuable in assessing cardiovascular risks. To accurately measure the detailed sec-surge, including its shape as BP rises and falls, we developed a beat-by-beat (BbB) BP monitoring device using tonometry. In addition, we developed an automatic sec-surge detection algorithm to help identify sec-surge cases in the overnight BbB BP data. The device and algorithm successfully detected sec-surges in patients with OSA. Our results demonstrated that sec-surge was associated with left ventricular hypertrophy and arterial stiffness independently of nocturnal BP level or variability. Sec-surge would be worth monitoring for assessing cardiovascular risks, in addition to nocturnal BP level. Nocturnal blood pressure (BP) surge in seconds (sec-surge) places heavy load on the cardiovascular system and can trigger cardiovascular events. To identify sec-surges, we developed a beat-by-beat BP monitoring device and a sec-surge detection algorithm. Furthermore, sec-surge was more related to cardiovascular risks than conventional nocturnal BP parameters.

Adequate management of nocturnal hypertension is crucial to reduce the risk of organ damage and cardiovascular events. The EARLY-NH study was a prospective, open-label, multicenter study conducted in Japanese patients with nocturnal hypertension who received esaxerenone treatment for 12 weeks. This post hoc analysis aimed to assess (1) the relationship between changes in morning home systolic blood pressure (SBP), bedtime home SBP, and nighttime home SBP based on changes in SBP and achievement rates of target SBP levels; and (2) the correlation between nighttime home SBP measurements using brachial and wrist home BP monitoring (HBPM) devices. This analysis evaluated 82 patients who completed the 12-week treatment period. Among those who achieved target morning home SBP (<135 mmHg) and target bedtime home SBP (<135 mmHg), the brachial HBPM device showed achievement rates of 63.6% and 56.4%, respectively, for target nighttime home SBP (<120 mmHg). The wrist device showed achievement rates of 66.7% and 63.4%, respectively, for the same targets. Significant correlations were observed between both devices for nighttime home SBP measurements at baseline (r = 0.790), Week 12 (r = 0.641), and change from baseline to Week 12 (r = 0.533) (all, p < .001). In this patient population, approximately 60% of individuals who reached target morning or bedtime home SBP levels <135 mmHg exhibited well-controlled nighttime home SBP. Although nighttime home SBP measurements obtained using both brachial and wrist HBPM devices displayed a significant correlation, the wrist device needs to be examined in more detail for clinical use.

BACKGROUND: Hypertensive disorders of pregnancy affect approximately 15% of pregnancies in the United States and are a leading cause of postpartum readmissions. Morbidity due to hypertension may be higher in the first several weeks postpartum. The ability to monitor blood pressure and intervene in the postpartum period is critical to reducing morbidity and mortality. LOCAL PROBLEM: At WellSpan Health, hypertensive disorders were increasing and a leading cause of severe maternal morbidity and readmission. INTERVENTIONS: A remote blood pressure monitoring app called BabyScripts™ myBloodPressure was implemented in September 2020. Prior to discharge postpartum, all patients with a diagnosis of a hypertensive disorder of pregnancy were given an automatic blood pressure cuff and instructions on how to monitor and track their blood pressure daily in the app. RESULTS: A total of 1,260 patients were enrolled in the BabyScripts™ myBloodPressure module between September 2020 and July 2022 across five maternity hospitals. Of those enrolled 74% ( n = 938) entered seven or more blood pressures, and of those who entered at least one blood pressure 9% ( n = 107) entered at least one critical range blood pressure ( ≥ 150 mmHg systolic and or ≥ 100 mmHg diastolic). CONCLUSION: Most women enrolled in the app were highly engaged and entered seven or more readings. Patients with critical blood pressures were identified; thus, the program has the potential to identify those at risk of severe complications. Barriers should be removed, and remote patient monitoring considered as a solution to improve postpartum assessment in patients with hypertensive disorders of pregnancy.

INTRODUCTION: Effective management of hypertension (HTN) is a priority in primary care. With telehealth now considered a staple care delivery method, uninsured and low-income patients without home blood pressure (BP) monitors may need additional attention and resources to achieve successful HTN control. METHODS: This prospective study at an underserved community clinic assessed the impact of distributing free BP monitors on patients' HTN control and therapy adherence. Enrollees were randomized into 2 groups, both completing 4 primary care physician (PCP) visits over a 6-month study period. Intervention participants collected home BP readings to report to their PCP and comparison participants completed an equivalent number of visits without having home BP data available for their PCP to review. Both groups completed an initial and final Therapy Adherence Scale (TAS) questionnaire. RESULTS: 263 patients were invited and 200 participants (mean age 50, 60% female, 19% Black, 67% Hispanic) completed the study. Intervention and comparison subjects featured comparable initial BP levels and TAS scores. After adjusting for age, race, ethnicity, sex, presence of diabetes and therapy adherence, intervention participants experienced higher odds of controlled HTN (OR 4.0; 95% Confidence Interval 2.1 to 7.7). A greater proportion of participants achieved BP control in the intervention arm compared with the comparison arm (82% vs 54% of participants, P < .001). TAS scores were higher in the intervention group (Mean = 44.1 vs 41.1; P < .001). DISCUSSION: The provision of free home BP monitors to low-income patients may feasibly and effectively improve BP control and therapy adherence.

INTRODUCTION: Widespread use of smartphone applications has opened new perspectives for home Blood Pressure monitoring based on mobile health (mHealth) technologies. Patient engagement has been dubbed 'the silver bullet of the century'. AIM: The aim was to identify the impact of engagement in patients with blood pressure using mHealth. METHODS: This scoping review was conducted in accordance with the Ark0sey and O'Malley framework. DATABASE: Pubmed, CINAHL, Scopus and PsycInfo. This review considered both qualitative and quantitative primary searches. We excluded articles belonging to grey literature, secondary literature and paediatric setting. Between September and November 2023, the review was carried out. RESULTS: A total of 569 documents were retrieved from the four databases. After the deduplication process, five articles were removed. The selection process based on titles and abstracts included 133 records. Ten studies were selected and analysed. The reviewers identified the following themes: device type and mobile applications, engagement, blood pressure control, health behaviours and hypertension knowledge. Self-management using digital technologies in the home is strongly linked to engagement, reduction and control of Blood Pressure, improved health practices and increased knowledge of hypertension. Healthcare interventions using IT platforms have had a significant impact on the health outcomes of patients diagnosed with hypertension. CONCLUSIONS: The review findings suggest the value of these technologies in improving patient engagement and, consequently, adherence to antihypertensive treatment and achieving blood pressure control rates, potentially reducing cardiovascular risk.

El rotular a un niño o adolescente de hipertenso no es una tarea fácil en la actualidad. Sabemos que el pilar para el diagnóstico de Hipertensión Arterial sigue siendo la presión arterial de consultorio; pero tenemos que tener en cuenta que, por su escasa reproducibilidad éste método tiene limitaciones. Hoy existen métodos complementarios reproducibles, validados y confiables como el Monitoreo Ambulatorio de la Presión Arterial (MAPA) y el Monitoreo Domiciliario de la Presión Arterial (MDPA) menos difundido en pediatría, que nos ayudan a llegar a un diagnostico correcto (AU)
Diagnosis of a hypertensive child or adolescent is not an easy task today. We know that the mainstay for diagnosing arterial hypertension remains the measuring of blood pressure at the office; however, it is necessary to bear in mind that, because of its low reproducibility, this method has limitations. Today there are reproducible, validated, and reliable complementary methods, such as ambulatory blood pressure monitoring (ABPM) and home blood pressure monitoring (HBPM), that are less widespread in pediatrics, which may be helpful to make an adequate diagnosis.(AU)

INTRODUCTION: Ambulatory blood pressure monitors have been used in salt loading and depletion protocols. However, the agreement between measurements made using ambulatory blood pressure monitors and those made with the sphygmomanometer has not been evaluated. OBJECTIVE: The objective of this study was to compare the concordance of the two methods of blood pressure measurements in protocols of acute salt loading and depletion. METHOD: Systolic blood pressure was measured using a sphygmomanometer at the completion of salt infusion (2 L NaCl 0.9 percent, 4 h) and salt depletion (furosemide, 120mg/day, p.o.) in 18 volunteers. Using the Pearson correlation coefficient (ρ), these readings were compared with the mean systolic blood pressure measured using the ambulatory blood pressure monitoring device during the following periods: 4 h of saline infusion and 12 h of salt depletion; 4 h of saline infusion and the last 6 h of salt depletion; 12 h of salt loading and the last 6 h of depletion; 12 h of salt loading and 12 h of depletion. Salt sensitivity was defined by a difference in the systolic blood pressure between salt loading and salt depletion greater than 10 mmHg when measured with the sphygmomanometer, and the Kappa analysis of concordance (K) was used with a significance level of P<0.05. RESULTS: Only the blood pressure readings obtained using the ambulatory blood pressure device during 4 h of intravenous NaCl and during 12 h of salt depletion showed a high correlation with the variation in the systolic blood pressure measured by the sphygmomanometer, with a full agreement with the salt sensitivity classification (p = 0.71; P = 0.001 and K=1). CONCLUSION: In acute salt loading and depletion protocols, an ambulatory blood pressure monitoring device should be used to record the blood pressure during the 4-h interval of salt infusion and 12-h interval of salt depletion.

FUNDAMENTO: A medida casual da pressão arterial (PA) pelos profissionais de saúde está sujeita a uma grande variabilidade, sendo necessário buscar novos métodos que possam superar essa limitação. OBJETIVO: Comparar e avaliar a correlação entre os níveis de PA obtidos por meio da automedida da pressão arterial (AMPA) com a medida casual e com a monitorização ambulatorial da pressão arterial (MAPA). MÉTODOS: Avaliamos hipertensos que realizaram as três metodologias de medida da PA com intervalo menor que 30 dias; as médias das pressões foram utilizadas para comparação e correlação. Foram empregados os aparelhos: OMRON 705 CP (medida casual), OMRON HEM 714 (AMPA) e SPACELABS 9002 (MAPA). RESULTADOS: Foram avaliados 32 pacientes, 50,09 por cento mulheres, idade média 59,7 (± 11,2) anos, média do IMC 26,04 (± 3,3) kg/m². Valores médios de pressão sistólica (PAS) e pressão diastólica (PAD) para a AMPA foram de 134 (± 15,71)mmHg e 79,32 (± 12,38) mmHg. Na medida casual as médias da PAS e PAD foram, respectivamente, 140,84 (± 16,15)mmHg e 85 (± 9,68) mmHg. Os valores médios da MAPA na vigília foram 130,47 (± 13,26) mmHg e 79,84 (± 9,82) mmHg para PAS e PAD, respectivamente. Na análise comparativa, a AMPA apresentou valores semelhantes aos da MAPA (p > 0,05) e diferentes da medida casual (p < 0,05). Na análise de correlação a AMPA foi superior à medida casual, considerando a MAPA como o padrão de referência nas medidas tensionais. CONCLUSÃO: A AMPA apresentou melhor comparação com a MAPA do que a medida casual e também se correlacionou melhor com a aquela, especialmente para a pressão diastólica, devendo ser considerada uma alternativa com baixo custo para o acompanhamento do paciente hipertenso.
BACKGROUND: Casual blood pressure (BP) measurement by healthcare professionals is subject to great variability and new methods are necessary to overcome this limitation. OBJECTIVE: To compare and assess the correlation between the BP levels obtained by self-measured BP (SMBP), casual BP measurement and ambulatory blood pressure monitoring (ABPM). METHODS: We assessed hypertensive individuals submitted to the three methods of BP measurement at an interval < 30 days; the BP means were used for comparison and correlation. The following devices were used: OMRON 705 CP (casual measurement), OMRON HEM 714 (SMBP) and SPACELABS 9002 (ABPM). RESULTS: A total of 32 patients were assessed, of which 50.09 percent were females, with a mean age of 59.7 (± 11.2), BMI mean of 26.04 (± 3.3) kg/m². Mean systolic (SBP) and diastolic blood pressure (DBP) for SMBP were 134 (± 15.71) mmHg and 79.32 (± 12.38) mmHg. The casual measurement means of SBP and DBP were, respectively, 140.84 (± 16.15) mmHg and 85 (± 9.68) mmHg. The mean values of ABPM during the wakefulness period were 130.47 (± 13.26) mmHg and 79.84 (± 9.82) mmHg for SBP and DBP, respectively. At the comparative analysis, the SMBP had similar results to those obtained at ABPM (p > 0.05) and different from the casual measurement (p < 0.05). At the analysis of correlation, SMBP values were higher than the casual measurements, considering ABPM as the reference standard in BP measurements. CONCLUSION: SMBP showed a better correlation with ABPM than the casual measurement and was also better correlated with the latter, especially regarding the DBP and should be considered as a low-cost alternative for the follow-up of the hypertensive patient.

En la medida casual los promedios de la PAS y PAD fueron, respectivamente, 140,84 (± 16,15) mmHg y 85 (± 9,68) mmHg. Los valores promedios de la MAPA en la vigilia fueron 130,47 (± 13,26) mmHg y 79,84 (± 9,82) mmHg para PAS y PAD, respectivamente. En el análisis comparativo, la AMPA tuvo valores similares a los de la MAPA (p > 0,05) y diferentes de la medida casual (p < 0,05). En el análisis de correlación la AMPA fue superior a la medida casual, considerando la MAPA como el estándar de referencia en las medidas tensionales. CONCLUSIÓN: La AMPA presentó una mejor comparación con la MAPA que la medida casual y también se correlacionó mejor con aquella, especialmente para la presión diastólica, debiendo ser considerada como una alternativa con bajo coste para el seguimiento del paciente hipertenso.

OBJETIVO: Avaliar o monitor OMRON 705-CP de medida de pressão arterial em adolescentes e adultos jovens. MÉTODOS: De acordo com o protocolo da British Hypertension Society e da Association for the Advancement of Medical Instrumentation, realizamos a validação do aparelho em 60 adolescentes. O monitor foi conectado em Y com a coluna de mercúrio e foram realizadas 4 medidas consecutivas e simultâneas, analisadas as independentes e calculadas as diferenças médias entre as pressões e o desvio padrão dessas diferenças. Os resultados foram analisados de acordo com o sistema de grau do protocolo utilizado. RESULTADOS: Foram avaliadas 240 medidas. A idade média dos pacientes foi 16,3 anos. Quando comparada a medida realizada pela coluna de mercúrio com o aparelho houve uma diferença < 15 mmHg em 97,9 por cento das medidas sistólicas e 98,8 por cento das diastólicas; uma diferença < 10 mmHg em 86,3 por cento das medidas sistólicas e 90,4 por cento das diastólicas, classificada como grau A; uma diferença < 5 mmHg em 59,1 por cento das medidas sistólicas e 67 por cento das medidas diastólicas, considerada pela classificação entre A/B. A diferença média e o desvio padrão dessa diferença na pressão sistólica foi de 2,91±6,42 mmHg e para a diastólica de 1,16±5,79 mmHg. CONCLUSAO: O monitor OMRON 705-CP mostrou-se válido para medidas de pressão arterial de adolescentes segundo o protocolo empregado.
