Background: Hypertension poses a significant risk as a complication of chronic kidney disease (CKD), contributing to its hastened advancement. Implementing ambulatory blood pressure monitoring (ABPM), a straightforward and non-invasive method proves beneficial in identifying masked hypertension. Methods: A cross-sectional study was carried out involving children aged 5–15 years diagnosed with CKD to estimate the difference in masked HTN prevalence between the 2014 and 2022 AHA ABPM guidelines. The study encompassed a comprehensive assessment, including 24-h blood pressure monitoring and was performed using ABPM. Left ventricular mass (LVM) was computed based on measurements obtained from M-mode echocardiography. PWV was determined by calculating the ratio of distance (D) to time (t). Results: We examined a cohort of 138 children diagnosed with CKD. Our findings reveal that, in accordance with the 2022 American Heart Association (AHA) ABPM guidelines, prevalence of masked hypertension stands at 29.7% marking a notable increase of 17.4% compared to the 2014 ABPM guidelines signifying a substantial proportion of undetected hypertensive cases. Furthermore, the prevalence of hypertension is 48.5% as detected by ABPM, marking a notable increase of 22.5%. Conclusions: A substantial occurrence of masked hypertension was identified in pediatric CKD patients through the application of ABPM. ABPM proves to be an effective tool for uncovering masked hypertension in children with CKD. [ABSTRACT FROM AUTHOR]

Abstract Background Hypertension is a leading cause of premature mortality and morbidity. Recent guidelines advocate for out-of-office blood pressure monitoring, including ambulatory and home BP monitoring, to better identify hypertension phenotypes like masked hypertension, white coat hypertension, and sustained hypertension. However, clinical inertia persists due to a lack of robust evidence on the effectiveness of screening these phenotypes and their association with cardiovascular and all-cause mortality. This systematic review and meta-analysis aims to evaluate the relationship between various hypertension phenotypes and future cardiovascular events and all-cause mortality to support the broader implementation of out-of-office BP monitoring. Main body Following PRISMA, Cochrane, and MOOSE guidelines, we conducted a comprehensive search in Pubmed, OvidSP, and Cochrane Central databases up to October 17, 2023. Eligible studies reported associations between hypertension phenotypes and cardiovascular or all-cause mortality, with normotension as the reference group. Hazard ratios with 95% confidence intervals (CIs) were pooled using random-effects models. Eight studies with 15,327 participants were included. Masked hypertension was associated with increased cardiovascular mortality (pooled HR 2.05, 95% CI 1.69–2.48). Sustained hypertension also showed a higher risk (pooled HR 2.42, 95% CI 2.12–2.76). WCH did not significantly increase cardiovascular mortality risk (pooled HR 1.18, 95% CI 0.98–1.42). For all-cause mortality, neither masked hypertension (pooled HR 2.10, 95% CI 0.91–4.88) nor white coat hypertension (pooled HR 1.96, 95% CI 0.71–5.42) showed significant increases. Conclusion Masked hypertension and sustained hypertension are linked to higher cardiovascular mortality compared to normotension, highlighting the importance of out-of-office BP monitoring to identify and manage high-risk phenotypes effectively. Further high-quality studies are needed to generalize these findings and support policy changes.

With the widespread use of ABPM, new phenotypes of essential hypertension have been uncovered. One of such phenotypes is the so-called masked hypertension wherein a patient has a normal office bp but hypertension on ABPM or HBPM. It is important to recognize this phenotype because it may be associated with HMOD in presence of normal office bp. We carried out a study to find out the prevalence of masked hypertension in patients who had office bp in high normal range with or without diabetes, CKD, alcohol intake, smoking, obesity, and sedentary lifestyle. The prevalence of masked hypertension was 17%. Statistically significant association was found between masked hypertension and obesity, diabetes and CKD. 29.4% of patients with masked hypertension had retinopathy, 17.9% had nephropathy, and 26.9% had LVH. Our study makes a strong case for screening for masked hypertension in all patients who present with high normal office bp with or without obesity, diabetes and CKD. [ABSTRACT FROM AUTHOR]

The article presents a study which described ambulatory blood pressure monitoring (ABPM) utilization in children with hypertension and children with conditions associated with masked hypertension. Topics discussed include utilization of ABPM by characteristics of patients aged five to 18 years, patient characteristics associated with ABPM utilization, and study limitations.

Background: Hypertension (HTN), especially masked hypertension, is one of the cardiovascular consequences of nephrotic syndrome. Masked hypertension cannot be identified during routine follow-up visits and adversely effects the patients' cardiac function. The purpose of this study was to use ambulatory blood pressure monitoring (ABPM) to evaluate the blood pressure status of children with nephrotic syndrome. Methods: Ninety children with nephrotic syndrome (NS) participated in this cross-sectional study, which was carried out at Cairo University Children Hospital's nephrology clinic (CUCH). A sphygmomanometer was used in the clinic to measure blood pressure, and a Meditech monitor was used for 24-hour ambulatory blood pressure monitoring (ABPM). Interventricular septum (IVS) was measured, and heart functions were evaluated, using echocardiography. Results: Two groups comprised the included patients: Group1 (n = 70): HTN group included masked and ambulatory hypertension, and Group 2 (n = 20): non-HTN group included normal blood pressure, white coat HTN and well controlled HTN, 35% of the studied cohort (n = 32/90) had masked HTN.The serum urea was significantly higher in HTN group than non-HTN group with p-value: 0.047, while the serum albumin was significantly lower in HTN group than non-HTN group with p-value: 0.017. The cut-off point of 9.9, the sensitivity and specificity of serum urea to predict the occurrence of hypertension in NS patients was 92.9% and 35% respectively, with p-value : 0.024 and 95% CI (0.534–0.798). The z score of IVS is significantly higher in group 1 (2.5 ± 1.2) when compared to group 2 (1.7 ± 2.1) with p-value: 0.025 and Among group 1, it was noticed that 74% (n = 52/70) of them were systolic non-dipper, also it was observed that the mean serum potassium and cholesterol were significantly higher among systolic non-dipper when compared with systolic dipper patients with p-values: 0.045 and 0.005 respectively. Conclusion: Children with nephrotic syndrome are particularly vulnerable to experience ambulatory hypertension and masked hypertension, which may adversely impact their cardiac condition because they are not detectable by standard blood pressure readings at the clinic.

BACKGROUND: Hypertension is a prevalent complication of Chronic Kidney Disease (CKD) and Ambulatory Blood Pressure Monitoring (ABPM) is the gold standard for diagnosis. The aim of our study was to assess the usefulness of obtaining ABPM and to identify barriers to ABPM in this pediatric patient population. METHOD: In this retrospective analysis of patients with CKD stage 3-5 who were seen in one academic medical centers outpatient Pediatric Nephrology clinics between 2018 and 2021, we performed logistic regression to evaluate for associations between demographic factors and odds of having an ABPM. RESULT: Among 96 patients included in the study, 48 patients carried a diagnosis of hypertension. 31 patients had ABPM performed with usable data. In those who had ABPM done, 21 had normotension and 10 had undertreated hypertension. Our study also showed 1 had masked hypertension and 5 had white coat hypertension or effect. We did not find a statistically significant difference in those who did or did not undergo ABPM evaluation based on gender, previous diagnosis of hypertension, distance from clinic, language preference, or racial or ethnic identity. CONCLUSION: ABPM is a useful tool in our CKD population for the diagnosis and management of hypertension. We did not identify specific barriers to ABPM in our CKD population, and there were no differences in patients who obtained ABPM when looking at specific demographic and disease characteristics. Given these findings, we recommend focusing on areas of future improvement in spheres of patient and provider education as well as better quantification using surveys to further illuminate barriers.

Twenty-four-hour ambulatory blood pressure monitoring (ABPM) is recognized as a reference tool for accurately diagnosing hypertension. Until a few years ago, this technique was restricted to use by specialists. Recently, however, due to the need for wider availability and thanks to technological innovation, simplification of analysis processes, and increasing recognition of the importance of this tool for the diagnosis of hypertension, ABPM is now also being used in non-specialist settings. In such settings, ABPM is used with a two-pronged approach: (i) independently by a general practitioner with the possibility of specialist supervision for particular and complex cases; (ii) in the non-medical setting (community pharmacies, home care services, etc.) where the healthcare provider is trained in the proper use of the technique, with the understanding a physician must be responsible for the final clinical reporting. Unfortunately, due to the increasingly wide diffusion of ABPM, there has been considerable confusion about management roles and responsibilities in recent years. To clarify competencies and roles and standardize the processes related to the technique's implementation and proper management, experts of the Blood Pressure Monitoring Working Group of the Italian Society of Hypertension have drafted this document with the aim of providing a quick and easy reference guide for training healthcare professionals in the field.

Background: Ambulatory Blood Pressure Monitoring (ABPM) is recommended for diagnosis and management of hypertension. We aimed to identify characteristics associated with physician action after receipt of abnormal findings. Methods: This was a retrospective cross-sectional analysis of patients 5–22 years old who underwent 24-h ABPM between 2003–2022, met criteria for masked or ambulatory hypertension, and had a pediatric nephrology clinic visit within 2 weeks of ABPM. "Action" was defined as medication change/initiation, lifestyle or adherence counseling, evaluation ordered, or interpretation with no change. Characteristics of children with/without 1 or more actions were compared using Student t-tests and Chi-square. Regression analyses explored the independent association of patient characteristics with physician action. Results: 115 patients with masked (n = 53) and ambulatory (n = 62) hypertension were included: mean age 13.0 years, 48% female, 38% Black race, 21% with chronic kidney disease, and 25% overweight/obesity. 97 (84%) encounters had a documented physician action. Medication change (52%), evaluation ordered (40%), and prescribed lifestyle change (35%) were the most common actions. Adherence counseling for medication and lifestyle recommendations were documented in 3% of encounters. 24-h, wake SBP load, and sleep DBP load were significantly higher among those with physician action. Patients with > 1 action had greater adiposity, SBP, and dipping. Neither age, obesity, nor kidney disease were independently associated with physician action. Conclusions: While most abnormal ABPMs were acted upon, 16% did not have a documented action. Greater BP load was one of the few characteristics associated with physician action. Of potential actions, adherence counseling was underutilized. [ABSTRACT FROM AUTHOR]

Background and Objectives: We evaluated the prevalence and characteristics of isolated nighttime masked uncontrolled hypertension (IN-MUCH) in treated patients. Materials and Methods: Participants aged 20 years or older who were on antihypertensive medication underwent three-day office blood pressure (BP) and 24 h ambulatory BP measurements. Hypertension phenotypes were classified as controlled hypertension (CH), isolated daytime masked uncontrolled hypertension (ID-MUCH), IN-MUCH, and daytime and nighttime masked uncontrolled hypertension (DN-MUCH). Results: Among 701 participants, 544 had valid BP data and controlled office BP (<140/90 mmHg). The prevalence of IN-MUCH was 34.9%, with a higher prevalence of men and drinkers than in those with CH. Patients with IN-MUCH had higher office systolic BP (SBP) and diastolic BP (DBP) than those with CH. The prevalence of IN-MUCH was 37.6%, 38.5%, and 27.9% in patients with optimal, normal, and high-normal office BP levels, respectively. Among IN-MUCH patients, 51.6% exhibited isolated uncontrolled DBP and 41.1% uncontrolled SBP and DBP. Younger age (p = 0.043), male sex (p = 0.033), and alcohol consumption (p = 0.011) were more prevalent in patients with isolated uncontrolled DBP than in those with uncontrolled SBP and DBP. Age and alcohol consumption were positively associated, whereas high-normal office BP exhibited a negative association with IN-MUCH. Conclusions: The IN-MUCH was significantly more prevalent in patients with normal or optimal office BP, posing treatment challenges. Further investigation is needed to determine whether differentiation between isolated uncontrolled DBP and combined uncontrolled SBP and DBP is necessary for prognostic assessment of IN-MUCH.

Background: In the in-clinic blood pressure (BP) recording setting, a sizable number of individuals with normal BP and approximately 30% of patients with chronic renal disease (CKD) exhibit elevated outpatient BP records. These individuals are known as masked hypertension (MHTN), and when they are on antihypertensive medications, but their BP is not controlled, they are called masked uncontrolled hypertension (MUHTN). The masked phenomenon (MP) (MHTN and MUHTN) increases susceptibility to end-organ damage (a two-fold greater risk for cardiovascular events and kidney dysfunction). The potential extension of the observed benefits of MP therapy, including a reduction in end-organ damage, remains questionable. Aim and methods: This review aims to study the diagnostic methodology, epidemiology, pathophysiology, and significance of MP management in end-organs, especially the kidneys, cardiovascular system, and outcomes. To achieve the purposes of this non-systematic comprehensive review, PubMed, Google, and Google Scholar were searched using keywords, texts, and phrases such as masked phenomenon, CKD and HTN, HTN types, HTN definition, CKD progression, masked HTN, MHTN, masked uncontrolled HTN, CKD onset, and cardiovascular system and MHTN. We restricted the search process to the last ten years to search for the latest updates. Conclusion: MHTN is a variant of HTN that can be missed if medical professionals are unaware of it. Early detection by ambulatory or home BP recording in susceptible individuals reduces end-organ damage and progresses to sustained HTN. Adherence to the available recommendations when dealing with masked phenomena is justifiable; however, further studies and recommendation updates are required. PLAIN LANGUAGE SUMMARY: Blood pressure tells us how much force the heart exerts on the blood vessels as it pumps blood. Normal blood pressure should be 120/80 mmHg, which generally decreases when a person is sleeping or sitting. High blood pressure or hypertension occurs when the blood pressure is too high. Hidden or masked hypertension (MH) is a type of high blood pressure. Masked hypertension was described as having high blood pressure readings even though the doctor's office or in-clinic showed normal blood pressure readings. This review aimed to teach people about various kinds of high blood pressure, focusing on hidden (masked) hypertension and how to recognise it, as well as its consequences, treatment, and new information.

Abstract There is a controversial debate regarding whether unattended blood pressure (BP) measurement should be regarded as the new gold standard of office BP measurement. Unattended BP measurement eliminates the white‐coat effect and reduces external influences on the patient. On the other hand, it might underestimate real‐life BP. The present study compares the prevalence of masked hypertension using attended versus unattended office BP measurements. We performed a cross‐sectional study on 213 patients in a general practitioner's outpatient clinic and compared attended and unattended office BP with 24h‐ambulatory BP monitoring (24h‐ABPM). Masked hypertension was defined as pressure ≥135/85 mmHg in daytime ABPM with office systolic BP

There is a controversial debate regarding whether unattended blood pressure (BP) measurement should be regarded as the new gold standard of office BP measurement. Unattended BP measurement eliminates the white‐coat effect and reduces external influences on the patient. On the other hand, it might underestimate real‐life BP. The present study compares the prevalence of masked hypertension using attended versus unattended office BP measurements. We performed a cross‐sectional study on 213 patients in a general practitioner's outpatient clinic and compared attended and unattended office BP with 24h‐ambulatory BP monitoring (24h‐ABPM). Masked hypertension was defined as pressure ≥135/85 mmHg in daytime ABPM with office systolic BP < 140/90 mmHg. Median attended and unattended office BPs were 140/86 and 134/80 mmHg with a median 24h‐BP of 129/79 mmHg and daytime ABP of 133/82 mmHg. The number of patients with masked hypertension was 45/213 (21.2%) using unattended and 23/213 (10.8%) using attended office BP measurements (p <.0001). Bland–Altman analysis revealed a 7.4 mmHg systolic and 6.2 mmHg diastolic bias between the attended versus unattended office BP, and two systolic and −1.7 mmHg diastolic biases between the unattended office BP and daytime ambulatory BP. In linear regression analysis, an unattended office BP of 134 mmHg corresponded to 140 mmHg in attended BP measurement. Using a cut‐off of 135/85 mmHg instead of 140/90 mmHg in unattended office BP measurement, the rate of masked hypertension was 26/213 (12.2%). Thus, unattended office BP measurement results in a substantial increase in the prevalence of masked hypertension using the traditional definition of hypertension. The present findings suggest that it might be reasonable to use a definition of 135/85 mmHg. [ABSTRACT FROM AUTHOR]

BACKGROUND An important prevalence (32%–45%) of masked hypertension has been reported in children with sickle cell disease (SCD). Stroke screening is well established using transcranial Doppler (TCD) ultrasound. The objectives of our proof-of-concept study in childhood SCD were to evaluate the prevalence of hypertension and its relationships with cerebral vasculopathy (TCD velocity) and to further evaluate in a subgroup of children the correlations of cardiovascular autonomic nervous system indices with TCD velocity. METHODS Ambulatory blood pressure measurement (ABPM) and TCD velocity were obtained in children with SCD and in a restricted sample, cardiac sympathovagal balance using heart rate variability analyses, baroreflex sensitivity, and pulse wave velocity were measured. RESULTS In 41 children with SCD (median age 14.0 years, 19 girls, SS/Sβ + thalassemia/SC: 33/2/6), ABPM results showed masked hypertension in 2/41 (5%, 95% confidence interval, 0–11) children, consistent with the prevalence in the general pediatric population, elevated blood pressure (BP) in 4/41 (10%) children, and a lack of a normal nocturnal dip in 19/41 children (46%). Children with increased TCD velocity had lower nocturnal dipping of systolic BP. In the 10 participants with extensive cardiovascular assessment, increased TCD velocity was associated with parasympathetic withdrawal and baroreflex failure. Exaggerated orthostatic pressor response or orthostatic hypertension was observed in 7/10 children that was linked to parasympathetic withdrawal. CONCLUSIONS Autonomic nervous system dysfunction, namely loss of parasympathetic modulation, of SCD contributes to increase TCD velocity but is not associated with an increased prevalence of masked hypertension.

Summary: Background: Masked hypertension is associated with target organ damage (TOD) and adverse health outcomes, but whether antihypertensive treatment improves TOD in patients with masked hypertension is unproven. Methods: In this multicentre, randomised, double-blind, placebo-controlled trial at 15 Chinese hospitals, untreated outpatients aged 30–70 years with an office blood pressure (BP) of

Fetal growth restriction (FGR) is a major risk factor for complicated pregnancy including stillbirth. The all-pathophysiology results in uteroplacental insufficiency. Hypertension chronic or pregnancy-related complicates the all-prenatal periods. The relationship between fetal growth restriction and hypertension is well-known and this risk increases with maternal age. Late-onset FGR is diagnosed >32 weeks. Masked hypertension (MH) is a phenotype of hypertension when clinic blood pressure is in the normal range in the office but elevated outside the office. This study examined the risk of late-onset FGR and masked hypertension at advanced maternal age. Sixty pregnant women over 40 years old were included in the study who delivered at our hospital with late-onset fetal growth restriction diagnosis. After taking detailed anamnesis from all individuals included in the study, detailed physical examination, obstetric examination and ambulatory blood pressure monitoring (ABPM) were performed. Women with maternal chronic hypertension, pregestational or gestational diabetes mellitus, chronic kidney disease, rheumatoid disease history, tobacco use, cardiac arrhythmia, fetal genetic abnormality or placental abnormality were excluded from the study. The prevalence of masked hypertension was statistically significantly higher in the group with late intrauterine growth. (n:13, 43% vs n:5, 16.7% p=0.02). Office systolic BP (125.5±4.1 mmHg vs 118.5±5.7 mmHg p=0.016), 24-hour systolic BP measurement (125±9 mmHg vs 119.7±5.7 mmHg p=0.03), and ambulatory nocturnal diastolic BP measurement (66.7±10 mmHg vs. 61.±5.5 mmHg p=0.03) was higher in the group with late FGR. Hypertension can lead to complications in the perinatal period. There is a bad association between FGR and hypertension. Masked hypertension should be considered especially in advanced age pregnant individuals with FGR. [Med-Science 2023; 12(4.000): 1193-7]

Cardiovascular disease remains the leading cause of mortality on a global scale. Individuals who possess risk factors for cardiovascular disease, such as high blood pressure (BP) and obesity, face an elevated risk of experiencing organ-specific pathophysiological changes. This damage includes pathophysiological changes in the heart and peripheral vascular systems, such as ventricular hypertrophy, arterial stiffening, and vascular narrowing and stenosis. Consequently, these damages are associated with an increased risk of developing severe cardiovascular outcomes including stroke, myocardial infarction, heart failure, and coronary heart disease. Among all the risk factors associated with cardiovascular disease, high blood pressure emerges as the most prominent. However, conventional resting BP measurement methods such as auscultatory or oscillometric methods may fail to identify many individuals with asymptomatic high BP. Recently, exercise BP has emerged as a valuable diagnostic tool for identifying real (high) blood pressure levels and assessing underlying cardiovascular risk, in addition to resting BP measurements in adults. Furthermore, numerous established factors, such as low cardiorespiratory fitness and high body fatness, have been confirmed to contribute to exercise BP and the associated cardiovascular risk. Modifying these factors may help reduce high exercise BP and, consequently, alleviate the burden of cardiovascular disease. A significant body of evidence has demonstrated cardiovascular disease in later life have their origins in early life. Children and adolescents with these cardiovascular risk factors also possess a greater propensity to develop cardiovascular diseases later in life. Nevertheless, the majority of previous studies on the clinical utility of exercise BP have been conducted in middle-to-older aged populations, often with pre-existing clinical conditions. Therefore, there is a need to investigate further of the factors influencing exercise BP in adolescence and its association with cardiovascular risk in early life. Our previously published work showed that exercise BP is a potential useful method to detect adolescents with increased cardiovascular risk. Children and adolescents with cardiovascular risk factors are more likely to develop cardiovascular diseases later in life. However, previous studies on the clinical utility of exercise BP have largely focused on middle-to-older aged populations with pre-existing clinical conditions. Therefore, there is a need to investigate further the factors influencing exercise BP in adolescence and its association with future cardiovascular risk. Our previous studies, which focused on exercise BP measured at submaximal intensity, have shown that exercise BP is a potentially useful method for identifying adolescents at increased cardiovascular risk. Our previous findings suggest that improving cardio-respiratory fitness and reducing body fatness may help to reduce the risk of developing cardiovascular disease and improve overall cardiovascular health. These findings have important implications for the development of effective prevention and early detection strategies, which can contribute to improved public health outcomes.

Aim. To establish the prevalence of masked uncontrolled hypertension (HTN) (MUH) in patients with diabetes or impaired glucose tolerance (IGT) and determine its clinical and hemodynamic characteristics.Material and methods. The study involved 87 patients who received regular antihypertensive therapy for hypertension and had established diabetes or IGT. The mean age of patients was 62,6±9,9 years, of which 51,7% were women, 48,3% — men. Type 2 diabetes was revealed in 77,7%, IGT — 22,8% of patients. For 24-hour blood pressure monitoring, BpLAB system (OOO Petr Telegin) was used; blood pressure (BP) was determined in the brachial artery, central blood pressure — in the aorta. We analyzed risk factors and target organ damage. The results were processed using the Excel Microsoft Office 2007 package and the Statistica 6.0 and 10.0 package from StatSoft, Inc (USA).Results. Uncontrolled hypertension was revealed in 59,8%, MUH — in 18,4%, controlled HTN — 21,8% of patients. Mean daytime and mean nighttime systolic BP in patients with MUH and uncontrolled HTN were comparable. Patients with controlled hypertension compared with MUH had lower mean day- and nighttime aortic BP by 27,1% (p

Background: The main benefit of home-based blood pressure monitoring (HBPM) is the potential approach to reduce the risk of white-coat hypertension (HTN) and to encourage patients to take ownership of their condition. This study was conducted to assess the role of HBPM in treatment follow-up in a cohort of hypertensive patients. Materials and methods: This was a prospective observational study conducted from December 2017 to May 2018. A total of 100 patients fulfilling the inclusion and exclusion criteria were selected by purposive sampling from Medicine Outdoor of Dhaka Medical College Hospital (DMCH). In total, 100 hypertensive patients were enrolled, and informed consent was obtained. Subsequently, the study subjects received information and training on BP self-management and performed 2 resting measurements per day for 4 days per week for 3 months. All measurements were performed using validated BP monitors. The study endpoints included patient awareness, attainment of BP goals, adherence to antihypertensive treatment, lifestyle modification, assessment of discrepancy between office and HBPM, and white coat HTN or masked HTN at 3 months. SPSS version 22.0 was used for data analysis and reporting. Results: Overall, the mean age was 57.76 ±12.60 years with a range of 34 - 80 years. Males were more prevalent than females, and the ratio was 1.17:1. The majority of cases (76.0%) had established HTN with a history of taking medication, whereas others were non-compliant with medications. Among them 47% had obesity, and 24% had diabetes mellitus. Of the patients, 91% adherence to HBP monitoring, 84.0% adherence to medication, and 75.0% achieved their target BP. The achievement of target blood pressure was significantly higher among the study subjects who adhered to HBP monitoring, and the p-value was < 0.04 (Fisher's Exact test). Conclusion: In a cohort of patients with arterial hypertension, information, and training on BP selfmeasurement and direct involvement of patients using HBPM led to improvement in BP control and could be an effective method by incorporating it into the usual care of hypertensive patients in the hypertension management center of the community.

Objective: We aimed to evaluate the clinical significance of the “unclassified” blood pressure phenotypes on left ventricular hypertrophy in children. Materials and Methods: All children evaluated with ambulatory blood pressure monitoring in the pediatric nephrology department between October 2018 and January 2021 were included in the study. Prehypertension, normotensive, white coat hypertension, masked hypertension, ambulatory hypertension groups and 2 other groups including increased blood pressure load, normal ambulatory blood pressure measurements, but normal (unclassified group 1) or high (unclassified group 2) office blood pressure measurements were defined according to the American Heart Association 2014 statement. Left ventricular mass index, left ventricular mass index/95 percentile values, and left ventricular hypertrophy ratios were compared between the groups separately to establish the influence of the unclassified cases. Results: A total of 497 children were included. There were 52 cases in normotensive, 47 cases in unclassified group 1, 50 cases in masked hypertension, 79 cases in white coat hypertension, 104 cases in unclassified group 2, and 165 cases in the ambulatory hypertension group. Left ventricular mass index/95 percentile and left ventricular hypertrophy in masked hypertension were significantly higher than normotensive but similar between normotensive and unclassified group 1 groups. Left ventricular hypertrophy was significantly higher in the ambulatory hypertension group compared to white coat hypertension, and similar between white coat hypertension and unclassified group 2 groups. Conclusion: Independent of age, we have found that interpretation of blood pressure load not only has a limited predictable effect on left ventricular hypertrophy but also causes a large group of patients to be unclassified.

BACKGROUND Emerging evidence suggests that a hypertensive response to exercise (HRE) during dynamic or isometric stress tests assessing cardiac function is predictive of hypertension and cardiovascular events such coronary artery disease, heart failure and stroke. Whether HRE represents a marker of masked hypertension (MH) in individuals with no prior history of hypertension is still unclear. This is also the case for the association between MH and hypertension-mediated organ damage (HMOD) in the HRE setting. METHODS We addressed this issue through a review and a meta-analysis of studies providing data on this topic in normotensive individuals undergone both to dynamic or static exercise and to 24-h blood pressure monitoring (ABPM). A systematic search was performed using Pub-Med, OVID, EMBASE and Cochrane library databases from inception up to February 28th 2023. RESULTS Six studies including a total of 1,155 untreated clinically normotensive individuals were considered for the review. Data provided by the selected studies can be summarized as follows: (i) HRE is a BP phenotype linked to a high prevalence of MH (27.3% in the pooled population); (ii) MH is, in turn, associated with a greater, consistent likelihood of echocardiographic left ventricular hypertrophy (OR: 4.93, CI: 2.16–12.2, P  < 0.0001) and vascular organ damage, as assessed by pulse wave velocity, (SMD: 0.34 ± 0.11, CI: 0.12–0.56, P  = 0002). CONCLUSIONS On the basis of this, albeit limited, evidence, the diagnostic work-up in individuals with HRE should primarily be addressed to look for MH as well as for markers of HMOD, a highly prevalent alteration in MH.

Abstract Background Hypertension is a prevalent complication of Chronic Kidney Disease (CKD) and Ambulatory Blood Pressure Monitoring (ABPM) is the gold standard for diagnosis. The aim of our study was to assess the usefulness of obtaining ABPM and to identify barriers to ABPM in this pediatric patient population. Method In this retrospective analysis of patients with CKD stage 3–5 who were seen in one academic medical center’s outpatient Pediatric Nephrology clinics between 2018 and 2021, we performed logistic regression to evaluate for associations between demographic factors and odds of having an ABPM. Result Among 96 patients included in the study, 48 patients carried a diagnosis of hypertension. 31 patients had ABPM performed with usable data. In those who had ABPM done, 21 had normotension and 10 had undertreated hypertension. Our study also showed 1 had masked hypertension and 5 had white coat hypertension or effect. We did not find a statistically significant difference in those who did or did not undergo ABPM evaluation based on gender, previous diagnosis of hypertension, distance from clinic, language preference, or racial or ethnic identity. Conclusion ABPM is a useful tool in our CKD population for the diagnosis and management of hypertension. We did not identify specific barriers to ABPM in our CKD population, and there were no differences in patients who obtained ABPM when looking at specific demographic and disease characteristics. Given these findings, we recommend focusing on areas of future improvement in spheres of patient and provider education as well as better quantification using surveys to further illuminate barriers.

Background and Objectives: We evaluated the prevalence and characteristics of isolated nighttime masked uncontrolled hypertension (IN-MUCH) in treated patients. Materials and Methods: Participants aged 20 years or older who were on antihypertensive medication underwent three-day office blood pressure (BP) and 24 h ambulatory BP measurements. Hypertension phenotypes were classified as controlled hypertension (CH), isolated daytime masked uncontrolled hypertension (ID-MUCH), IN-MUCH, and daytime and nighttime masked uncontrolled hypertension (DN-MUCH). Results: Among 701 participants, 544 had valid BP data and controlled office BP (p = 0.043), male sex (p = 0.033), and alcohol consumption (p = 0.011) were more prevalent in patients with isolated uncontrolled DBP than in those with uncontrolled SBP and DBP. Age and alcohol consumption were positively associated, whereas high-normal office BP exhibited a negative association with IN-MUCH. Conclusions: The IN-MUCH was significantly more prevalent in patients with normal or optimal office BP, posing treatment challenges. Further investigation is needed to determine whether differentiation between isolated uncontrolled DBP and combined uncontrolled SBP and DBP is necessary for prognostic assessment of IN-MUCH.

Rationale & objectiveObservational studies have reported a U-shaped association between blood pressure (BP) before a hemodialysis session and death. In contrast, because a linear association between out-of-dialysis-unit BP and death has been reported, home BP may be a better target for treatment. To test the feasibility of this approach, we conducted a pilot trial of treating home versus predialysis BP in hemodialysis patients.Study designA 4-month, parallel, randomized, controlled trial.Settings & participants50 prevalent hemodialysis patients in San Francisco and Seattle. Participants were randomly assigned using 1:1 block randomization, stratified by site.InterventionsTo target home systolic BP (SBP) of 100-200mm Hg; 0.2% vs 0%) or low (defined as

The coronavirus disease 2019 (COVID-19) pandemic and the subsequent lockdown profoundly affected almost all aspects of daily life including health services worldwide. The established risk factors for increased blood pressure (BP) and hypertension may also demonstrate significant changes during the pandemic. This study aims to determine the impact of the COVID-19 pandemic on BP control and BP phenotypes as assessed with 24-hour ambulatory BP monitoring (ABPM). This is a multi-centre, observational, retrospective and comparative study involving Excellence Centres of the European Society of Hypertension across Europe. Along with clinical data and office BP, ABPM recordings will be collected in adult patients with treated arterial hypertension. There will be two groups in the study: Group 1 will consist of participants who have undergone two ABPM recordings - the second one occurring during the COVID-19 pandemic, i.e. after March 2020, and the first one 9–15 months prior to the second. Participants in Group 2 will have two repeated ABPM recordings - both performed before the pandemic within a similar 9–15 month interval between the recordings. Within each group, we will analyse and compare BP variables and phenotypes (including averaged daytime and night-time BP, BP variability, dipper and non-dipper status, white-coat and masked hypertension) between the two respective ABPM recordings and compare these changes between the two groups. The target sample size will amount to least 590 participants in each of the study groups, which means a total of at least 2360 ABPM recordings overall. As a result, we expect to identify the impact of a COVID-19 pandemic on blood pressure control and the quality of medical care in order to develop the strategy to control cardiovascular risk factors during unpredictable global events. What is the context? A wide range of daily activities, including health care worldwide, were deeply affected by the Coronavirus disease 2019 pandemic and the subsequent lockdown. What is new? Our multicenter study will examine the impact of the COVID-19 pandemic on blood pressure control in hypertensive patients across Europe by analysing results of 24-hour ambulatory blood pressure monitoring. What is the impact? Optimising strategies for dealing with future unpredictable global situations will depend on understanding how the pandemic affected blood pressure control.

Fetal growth restriction (FGR) is a major risk factor for complicated pregnancy including stillbirth. The all-pathophysiology results in uteroplacental insufficiency. Hypertension chronic or pregnancy-related complicates the all-prenatal periods. The relationship between fetal growth restriction and hypertension is well-known and this risk increases with maternal age. Late-onset FGR is diagnosed >32 weeks. Masked hypertension (MH) is a phenotype of hypertension when clinic blood pressure is in the normal range in the office but elevated outside the office. This study examined the risk of late-onset FGR and masked hypertension at advanced maternal age. Sixty pregnant women over 40 years old were included in the study who delivered at our hospital with late-onset fetal growth restriction diagnosis. After taking detailed anamnesis from all individuals included in the study, detailed physical examination, obstetric examination and ambulatory blood pressure monitoring (ABPM) were performed. Women with maternal chronic hypertension, pregestational or gestational diabetes mellitus, chronic kidney disease, rheumatoid disease history, tobacco use, cardiac arrhythmia, fetal genetic abnormality or placental abnormality were excluded from the study. The prevalence of masked hypertension was statistically significantly higher in the group with late intrauterine growth. (n:13, 43% vs n:5, 16.7% p=0.02). Office systolic BP (125.5±4.1 mmHg vs 118.5±5.7 mmHg p=0.016), 24-hour systolic BP measurement (125±9 mmHg vs 119.7±5.7 mmHg p=0.03), and ambulatory nocturnal diastolic BP measurement (66.7±10 mmHg vs. 61.±5.5 mmHg p=0.03) was higher in the group with late FGR. Hypertension can lead to complications in the perinatal period. There is a bad association between FGR and hypertension. Masked hypertension should be considered especially in advanced age pregnant individuals with FGR. [ABSTRACT FROM AUTHOR]

Hypertension is frequent in children with chronic kidney disease (CKD). Its prevalence varies according to CKD stage and cause. It is relatively uncommon in children with congenital kidney disease, while acquired kidney disease is associated with a higher prevalence of hypertension. Studies in children with CKD utilizing ambulatory blood pressure monitoring also showed a high prevalence of masked hypertension. Uncontrolled and longstanding hypertension in children is associated with progression of CKD. Aggressive treatment of high blood pressure should be an essential part of care to delay CKD progression in children. [ABSTRACT FROM AUTHOR]

BACKGROUND: Home blood pressure (BP) is an important component of digital strategies for hypertension management. However, no studies have used the same device to investigate 24-hour BP control status in relation to different home BP control thresholds. METHODS: Participants in the general practitioner-based, multicenter HI-JAMP study (Home-Activity Information and Communication Technology-Based Japan Ambulatory Blood Pressure Monitoring Prospective) underwent office BP measurement, then 24hour ambulatory BP monitoring, then home BP monitoring for 5 days. A validated all-in-one BP monitoring device was used to measure office, home, and ambulatory BP. Baseline data were used to investigate ambulatory BP control status in individuals with well-controlled home BP based on the different guideline thresholds (125/75 mm Hg, 130/80 mm Hg, and 135/85 mm Hg). RESULTS: Data from 2269 patients were analyzed. For individuals with well-controlled home BP <135/85 mm Hg (59.5% of the total population), the prevalence of uncontrolled 24-hour (≥130/80 mm Hg), daytime (≥135/85 mm Hg), and nighttime ambulatory BP (≥120/70 mm Hg) was 19.9%, 18.5%, and 33.6%, respectively. Corresponding prevalence rates in the 42.7% of participants with well-controlled home BP <130/80 mm Hg were 13.4%, 12.9%, and 26.0%, and when well- controlled home BP was strictly defined as <125/75 mm Hg (23.9% of the population), prevalence of rates of uncontrolled 24-hour, daytime, and nighttime ambulatory BP were 7.0%, 9.0%, and 15.3%, respectively. CONCLUSIONS: Home BP control status defined using different thresholds could predict 24-hour ambulatory BP control status in treated hypertension. One-third of individuals still had uncontrolled nocturnal hypertension when home BP was controlled to <135/85 mm Hg, but ambulatory BP was quite well controlled when home BP was <125/75 mm Hg.

Masked hypertension (MH) occurs when office blood pressure is normal, but hypertension is confirmed using out-of-office blood pressure measures. Hypertension is a risk factor for subclinical cardiovascular outcomes, including left ventricular hypertrophy, increased left ventricular mass index, carotid intima media thickness, and pulse wave velocity. However, the risk factors for ambulatory blood pressure monitoring defined M H and its association with subclinical cardiovascular outcomes are unclear. A systematic literature search on 9 databases included English publications from 1974 to 2023. Pediatric MH prevalence was stratified by disease comorbidities and compared with the general pediatric population. We also compared the prevalence of left ventricular hypertrophy, and mean differences in left ventricular mass index, carotid intima media thickness, and pulse wave velocity between MH versus normotensive pediatric patients. Of 2199 screened studies, 136 studies (n=28 612; ages 4-25 years) were included. The prevalence of MH in the general pediatric population was 10.4% (95% CI, 8.00-12.80). Compared with the general pediatric population, the risk ratio (RR) of MH was significantly greater in children with coarctation of the aorta (RR, 1.91), solid-organ or stem-cell transplant (RR, 2.34), chronic kidney disease (RR, 2.44), and sickle cell disease (RR, 1.33). MH patients had increased risk of subclinical cardiovascular outcomes compared with normotensive patients, including higher left ventricular mass index (mean difference, 3.86 g/m27 [95% CI, 2.51-5.22]), left ventricular hypertrophy (odds ratio, 2.44 [95% CI, 1.50-3.96]), and higher pulse wave velocity (mean difference, 0.30 m/s [95% CI, 0.14-0.45]). The prevalence of MH is significantly elevated among children with various comorbidities. Children with MH have evidence of subclinical cardiovascular outcomes, which increases their risk of long- term cardiovascular disease. [ABSTRACT FROM AUTHOR]

Abstract Background The prevalence of obesity-related co-morbidities is rising parallel to the childhood obesity epidemic. High blood pressure (BP), as one of these co-morbidities, is detected nowadays at increasingly younger ages. The diagnosis of elevated BP and hypertension, especially in the childhood population, presents a challenge to clinicians. The added value of ambulatory blood pressure measurement (ABPM) in relation to office blood pressure (OBP) measurements in obese children is unclear. Furthermore, it is unknown how many overweight and obese children have an abnormal ABPM pattern. In this study we evaluated ABPM patterns in a population of overweight and obese children and adolescents, and compared these patterns with regular OBP measurements. Methods In this cross-sectional study in overweight or obese children and adolescents aged 4–17 years who were referred to secondary pediatric obesity care in a large general hospital in The Netherlands, OBP was measured during a regular outpatient clinic visit. Additionally, all participants underwent a 24-hour ABPM on a regular week-day. Outcome measures were OBP, mean ambulatory SBP and DBP, BP load (percentage of readings above the ambulatory 95th blood pressure percentiles), ambulatory BP pattern (normal BP, white-coat hypertension, elevated BP, masked hypertension, ambulatory hypertension), and BP dipping. Results We included 82 children aged 4–17 years. They had a mean BMI Z-score of 3.3 (standard deviation 0.6). Using ABPM, 54.9% of the children were normotensive (95% confidence interval 44.1–65.2), 26.8% had elevated BP, 9.8% ambulatory hypertension, 3.7% masked hypertension, and 4.9% white-coat hypertension. An isolated night-time BP load > 25% was detected in almost a quarter of the children. 40% of the participants lacked physiologic nocturnal systolic BP dipping. In the group of children with normal OBP, 22.2% turned out to have either elevated BP or masked hypertension on ABPM. Conclusions In this study a high prevalence of abnormal ABPM patterns in overweight or obese children and adolescents was detected. Additionally, OBP poorly correlated with the child’s actual ABPM pattern. Herewith, we emphasized the usefulness of ABPM as an important diagnostic tool in this population.
