RESUMEN

BACKGROUND: Although aging and being of African descent are well-known risk factors for masked uncontrolled hypertension (MUCH), data on MUCH among elderly black sub-Saharan Africans (BSSA) are limited. Furthermore, it is unclear whether the determinants of MUCH in younger individuals differ from those in the elderly. OBJECTIVE: This study aimed to determine the prevalence and risk factors associated with MUCH in both elderly and younger BSSA individuals. METHODS: In this study, 168 patients with treated hypertension were assessed for medical history, clinical examination, fundoscopy, echocardiography, and laboratory data. All patients underwent ambulatory blood pressure (BP) monitoring for 24 h. MUCH was diagnosed if the average 24-h mean BP ≥ 130/80 mmHg, the daytime mean BP ≥ 135/85 mmHg, and/or the nighttime mean BP ≥ 120/70 mmHg, despite controlled clinic BP (≤ 140/90 mmHg). Logistic regression analysis was performed to assess independent factors associated with MUCH, including elderly and younger adults separately. P-values < 0.05 were used to indicate statistical significance. RESULTS: Of the 168 patients aged 53.6 ± 11.6 years, 92 (54.8%) were men, with a sex ratio of 1.2, and, 66 (39%) were aged ≥ 60 years. The proportion of patients with MUCH (27.4% for all patients) was significantly higher (p = 0.002) among elderly patients than among younger patients (45.5% vs. 15.7%). Diabetes mellitus (adjusted odds ratio [aOR], 2.44; 95% confidence interval [CI], 1.27-4.46; p = 0.043), anemia (aOR, 3.18; 95% CI, 1.07-5.81; p = 0.043), hypertensive retinopathy (aOR, 4.50; 95% CI, 1.57-5.4; p = 0.043), and left ventricular hypertrophy (aOR, 4.48; 95% CI, 2.26-8.35; p = 0.043) were independently associated with MUCH in the elderly. In younger individuals, male gender (aOR, 2.16; 95% CI, (1.33-4.80); p = 0.029), obesity (aOR, 3.02; 95% CI, (1.26-5.32); p = 0.001), and left ventricular hypertrophy (LVH) (aOR, 3.08; 95% CI, (2.14-6.24); p = 0.019) were independently associated with MUCH were independently associated with MUCH. CONCLUSION: MUCH is more prevalent among elderly than among younger BSSA individuals. Determinants of MUCH vary by age. MUCH prevention and management strategies should be age-specific.

RESUMEN

OBJECTIVE: Accurate measurement of arterial blood pressure (BP) is crucial for the diagnosis, monitoring, and treatment of hypertension. This narrative review highlights the challenges associated with conventional (cuff-based) BP measurement and potential solutions. This work covers each method of cuff-based BP measurement, as well as cuffless alternatives, but is primarily focused on ambulatory BP monitoring. RESULTS: Manual BP measurement requires stringent training and standardized protocols which are often difficult to ensure in stressful and time-restricted clinical office blood pressure monitoring (OBPM) scenarios. Home Blood pressure monitoring (HBPM) can identify white-coat and masked hypertension but strongly depends on patient adherence to measurement techniques and procedure. The widespread use of nonvalidated automated HBPM devices raises further concerns about measurement accuracy. Ambulatory blood pressure measurement (ABPM) may be used in addition to OBPM. It is recommended to diagnose white-coat and masked hypertension as well as nocturnal BP and dipping, which are the BP values most predictive for major adverse cardiac events. Nonetheless, ABPM is limited by its non-continuous nature and susceptibility to measurement artefacts. This leads to poor overall reproducibility of ABPM results, especially regarding clinical parameters such as BP variability or dipping patterns. CONCLUSIONS: Cuff-based BP measurement, despite some limitations, is vital for cardiovascular health assessment in clinical practice. Given the wide range of methodological limitations, the paradigm's potential for improvement is not yet fully realized. There are impactful and easily incorporated opportunities for innovation regarding the enhancement of measurement accuracy and reliability as well as the clinical interpretation of the retrieved data. There is a clear need for continued research and technological advancement to improve BP measurement as the premier tool for cardiovascular disease detection and management.


Accurate blood pressure measurement is crucial for diagnosing, monitoring, and treating hypertension and preventing cardiovascular diseases.Manual blood pressure monitoring is common but may not always be reliable due to the stress and time constraints in clinical settings. It also fails to detect white-coat and masked hypertension.Home blood pressure monitoring helps to identify white-coat and masked hypertension but depends on how well patients follow the measurement instructions. Many devices are not validated, raising concerns about their accuracy.Ambulatory blood pressure measurement may be used in addition to office blood pressure measurement because of its better reproducibility and higher predictive value. It is recommended to diagnose white-coat and masked hypertension as well as nocturnal BP and dipping. However, it and can be prone to errors, affecting the reliability of results like BP variability or night-time dipping patterns.Patient's posture, physical activity, and conditions like atrial fibrillation can influence BP readings.Automated BP devices often have limitations in detecting measurement artefacts, underscoring the need for technological improvements.Despite its limitations, cuff-based blood pressure measurement is essential in everyday clinical practice but has unlocked potential for improvement.

RESUMEN

The values used to define white-coat and masked blood pressure (BP) effects are usually arbitrary. This study aimed at investigating the accuracy of various cutoffs based on the differences (ΔBP) between office BP (OBP) and 24h-ambulatory BP monitoring (ABPM) to identify white-coat (WCH) and masked (MH) hypertension, which are phenotypes coupled with adverse prognosis. This cross-sectional study included 11,350 [Derivation cohort; 45% men, mean age = 55.1 ± 14.1 years, OBP = 132.1 ± 17.6/83.9 ± 12.5 mmHg, 24 h-ABPM = 121.6 ± 11.4/76.1 ± 9.6 mmHg, 25% using antihypertensive medications (AH)] and 7220 (Validation cohort; 46% men, mean age = 58.6 ± 15.1 years, OBP = 136.8 ± 18.7/87.6 ± 13.0 mmHg, 24 h-ABPM = 125.5 ± 12.6/77.7 ± 10.3 mmHg; 32% using AH) unique individuals who underwent 24 h-ABPM. We compared the sensitivity, specificity, positive and negative predictive values and area under the curve (AUC) of diverse ΔBP cutoffs to detect WCH (ΔsystolicBP/ΔdiastolicBP = 28/17, 20/15, 20/10, 16/11, 15/9, 14/9 mmHg and ΔsystolicBP = 13 and 10 mmHg) and MH (ΔsystolicBP/ΔdiastolicBP = -14/-9, -5/-2, -3/-1, -1/-1, 0/0, 2/2 mmHg and ΔsystolicBP = -5 and -3mmHg). The 20/15 mmHg cutoff showed the best AUC (0.804, 95%CI = 0.794-0.814) to detect WCH, while the 2/2 mmHg cutoff showed the highest AUC (0.741, 95%CI = 0.728-0.754) to detect MH in the Derivation cohort. Both cutoffs also had the best accuracy to detect WCH (0.767, 95%CI = 0.754-0.780) and MH (0.767, 95%CI = 0.750-0.784) in the Validation cohort. In secondary analyses, these cutoffs had the best accuracy to detect individuals with higher and lower office-than-ABPM grades in both cohorts. In conclusion, the 20/15 and 2/2 mmHg ΔBP cutoffs had the best accuracy to detect hypertensive patients with WCH and MH, respectively, and can serve as indicators of marked white-coat and masked BP effects derived from 24 h-ABPM.

RESUMEN

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.


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.

RESUMEN

BACKGROUND AND AIMS: Guidelines suggest similar blood pressure (BP) targets in patients with and without diabetes and recommend ambulatory BP monitoring (ABPM) to diagnose and classify hypertension. It was explored whether different levels of ambulatory and office BP and different hypertension phenotypes associate with differences of risk in diabetes and no diabetes. METHODS: This analysis assessed outcome data from the Spanish ABPM Registry in 59 124 patients with complete available data. The associations between office, mean, daytime, and nighttime ambulatory BP with the risk in patients with or without diabetes were explored. The effects of diabetes on mortality in different hypertension phenotypes, i.e. sustained hypertension, white-coat hypertension, and masked hypertension, compared with normotension were studied. Analyses were done with Cox regression analyses and adjusted for demographic and clinical confounders. RESULTS: A total of 59 124 patients were recruited from 223 primary care centres in Spain. The majority had an office systolic BP >140 mmHg (36 700 patients), and 23 128 (40.6%) patients were untreated. Diabetes was diagnosed in 11 391 patients (19.2%). Concomitant cardiovascular (CV) disease was present in 2521 patients (23.1%) with diabetes and 4616 (10.0%) without diabetes. Twenty-four-hour mean, daytime, and nighttime ambulatory BP were associated with increased risk in diabetes and no diabetes, while in office BP, there was no clear association with no differences with and without diabetes. While the relative association of BP to CV death risk was similar in diabetes compared with no diabetes (mean interaction P = .80, daytime interaction P = .97, and nighttime interaction P = .32), increased event rates occurred in diabetes for all ABPM parameters for CV death and all-cause death. White-coat hypertension was not associated with risk for CV death (hazard ratio 0.86; 95% confidence interval 0.72-1.03) and slightly reduced risk for all-cause death in no diabetes (hazard ratio 0.89; confidence interval 0.81-0.98) but without significant interaction between diabetes and no diabetes. Sustained hypertension and masked hypertension in diabetes and no diabetes were associated with even higher risk. There were no significant interactions in hypertensive phenotypes between diabetes and no diabetes and CV death risk (interaction P = .26), while some interaction was present for all-cause death (interaction P = .043) and non-CV death (interaction P = .053). CONCLUSIONS: Diabetes increased the risk for all-cause death, CV, and non-CV death at every level of office and ambulatory BP. Masked and sustained hypertension confer to the highest risk, while white-coat hypertension appears grossly neutral without interaction of relative risk between diabetes and no diabetes. These results support recommendations of international guidelines for strict BP control and using ABPM for classification and assessment of risk and control of hypertension, particularly in patients with diabetes. CLINICAL TRIAL REGISTRATION: Not applicable.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Blood pressure (BP) measurement is affected by multiple variables which influence clinical management decisions and patient outcomes. Around 24-hour ambulatory blood pressure monitoring (ABPM) avoids incorrect diagnosis of hypertension (HT), and unnecessary treatment and provides the best prediction of cardiovascular (CV) risk. Clinically important phenotypes of HT such as masked HT (masked HT), white coat HT (white coat HT), and nocturnal HT (nocturnal HT) may be missed by not incorporating ambulatory BP monitoring in practice. However, lack of device availability, operational difficulties, and cost remain barriers to its widespread acceptance in India. In this review, we discuss the when, what, who, why, and where (5Ws) relevant to ABPM measurement.

RESUMEN

BACKGROUND: This study aimed to elucidate the prognostic role of Masked Morning Hypertension (MMH) in non-dialysis-dependent chronic kidney disease (NDD-CKD). METHODS: 2,130 NDD-CKD patients of the inpatient department were categorized into four blood pressure (BP) groups: clinical normotension (CH-), clinical hypertension (CH+) with morning hypertension (MH+), and without MH+ (MH-) respectively. The correlation between these four BP types and the primary (all-cause mortality) and secondary endpoints (cardio-cerebrovascular disease [CVD] and end-stage kidney disease [ESKD]) was analyzed. RESULTS: The prevalence of MH and MMH were 47.4% and 14.98%, respectively. Morning hypertension independently increased the risk of all-cause mortality (P = 0.004) and CVD (P < 0.001) but not ESKD (P = 0.092). Masked morning hypertension was associated with heightened all-cause mortality (HR = 4.22, 95% CI = 1.31-13.59; P = 0.02) and CVD events (HR = 5.14, 95% CI = 1.37-19.23; P = 0.02), with no significant association with ESKD (HR = 1.18, 95% CI = 0.65-2.15; P = 0.60). When considering non-CVD deaths as a competing risk factor, a high cumulative incidence of CVD events was observed in the MMH group (HR = 5.16, 95% CI = 1.39-19.08). CONCLUSIONS: MMH is an independent risk factor for all-cause mortality and combined cardiovascular and cerebrovascular events in NDD-CKD patients, underscoring its prognostic significance. This highlights the need for comprehensive management of MH in this population.

RESUMEN

BACKGROUND: The increasing prevalence of childhood obesity has led to a corresponding increase in hypertension among children, necessitating early identification of subclinical target organ damage for accurate cardiovascular risk assessment. However, in the pediatric population, there is a paucity of literature comparing ambulatory and home blood pressure monitoring, and this knowledge gap is exacerbated by limited access to ambulatory blood pressure monitoring (ABPM) facilities, particularly in developing countries, where pediatricians often resort to home blood BP monitoring as the preferred option. METHODS: In this cross-sectional study with 60 obese children (aged 5-18 years) at tertiary health care in central India, we aimed to comprehensively characterize blood pressure profiles, including office, ambulatory, and home, and investigated their correlations with indicators of end-organ damage. RESULTS: Among 60 children, 26 (43.3%) participants were found to be hypertensive based on 24-hour-ABPM evaluation. Masked hypertension (MH) and white coat hypertension (WCH) were observed in 21.6% and 13.3%, respectively. Surprisingly, 20% of participants were identified as hypertensive through 7-day home BP monitoring (HBPM). A notable discordance of 36.6% was between HBPM and ABPM results. Moreover, 26.7% of the children had end-organ damage, with higher odds associated with night-time systolic ambulatory hypertension in the adjusted regression model (OR = 1.06, 95% CI: 1.03-1.10, P < 0.001). CONCLUSIONS: The study highlights 24-hour ABPM's vital role in classifying hypertensive status, especially in high-risk children. The diagnostic performance of HBPM shows poor sensitivity in detecting MH and lower specificity in identifying WCH compared to ABPM. This limitation translates to missed opportunities for early preventive interventions.

RESUMEN

Ambulatory Blood Pressure Monitoring (ABPM) is considered the best method for obtaining a reliable estimation of the true blood pressure. Average values obtained during the whole 24-hour period, or during daytime and nighttime periods are better correlated with the risk of mortality and cardiovascular disease compared to clinic or office blood pressure. Indeed, nighttime blood pressure, a measure only obtained through ABPM, is the most powerful risk predictor. ABPM is complementary to clinic blood pressure measurement and allows the definition of blood pressure phenotypes, such as "white-coat or masked hypertension, when clinic and ABPM measurements show discrepancy in normal values. Additional potentially relevant features include blood pressure variability, such as nocturnal blood pressure decline, morning surge or short-term variability, as determined by standard deviation or the coefficient of variation.

RESUMEN

OBJECTIVES: Optimal blood pressure (BP) control is key to prevent cardiovascular complications in patients with chronic kidney disease (CKD). We described the prevalence and factors associated with masked hypertension in CKD. METHODS: We analyzed 1113 ambulatory 24-h BP monitoring (ABPM) records of 632 patients referred for kidney function evaluation. Masked hypertension was defined as office BP less than 140/90 mmHg but daytime BP at least 135/85 mmHg or nighttime BP at least 120/70 mmHg. Factors associated with masked hypertension were assessed with mixed logistic regression models. RESULTS: At inclusion, 424 patients (67%) had controlled office BP, of whom 56% had masked hypertension. In multivariable analysis conducted in all visits with controlled office BP ( n  = 782), masked hypertension was positively associated with male sex [adjusted OR (95% confidence interval) 1.91 (1.16-3.27)], sub-Saharan African origin [2.51 (1.32-4.63)], BMI [1.11 (1.01-1.17) per 1 kg/m 2 ], and albuminuria [1.29 [1.12 - 1.47] per 1 log unit), and was negatively associated with plasma potassium (0.42 [0.29 - 0.71] per 1 mmol/L) and 24-h urinary potassium excretion (0.91 [0.82 - 0.99] per 10 mmol/24 h) as well as the use of renin-angiotensin-aldosterone (RAAS) blockers (0.56 [0.31 - 0.97]) and diuretics (0.41 [0.27 - 0.72]). CONCLUSION: Our findings support the routine use of ABPM in CKD, as more than half of the patients with controlled office BP had masked hypertension. Weight control, higher potassium intake (with caution in advanced CKD), correction of hypokalemia, and larger use of diuretics and RAAS blockers could be potential levers for better out-of-office BP control.

RESUMEN

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/Sß + 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.

RESUMEN

BACKGROUND: One of the long-term complications after hematopoietic stem cell transplantation (HSCT) is hypertension (HT). Previous studies showed that 10-15% of children post-HSCT had office HT, but only a few studies used ambulatory blood pressure monitoring (ABPM). The present study was aimed at exploring the frequency and factors associated with ABPM HT in children post-HSCT. METHODS: Patients aged ≥ 6 years who survived ≥ 2 years after HSCT were enrolled. Clinical and ABPM data were reviewed. ABPM HT was defined according to the 2022 American Heart Association guidelines. Factors associated with HT were analyzed by logistic regression. RESULTS: Ninety-eight (60 males) patients with a mean age of 15.1 years and a median follow-up time at 4.5 years after HSCT were included. Fifteen patients (15.3%) had ABPM HT (2 ambulatory HT and 13 masked HT). The ABPM HT group had a significantly older age (19 vs. 14 years), a higher proportion of males (87% vs. 57%), a higher office systolic BP index (0.93 vs. 0.85), a higher office diastolic BP index (0.96 vs. 0.82) and a higher proportion of current use of prednisolone and tacrolimus than those in the normal ABPM group. Multivariate analysis revealed that office diastolic BP index was associated with ABPM HT. Left ventricular mass index was significantly correlated with ABPM but not with office BP parameters. CONCLUSIONS: HT in children post-HSCT was not uncommon and most could not be detected with office BP measurement. A diastolic BP index can be used as a screening tool for HT.

RESUMEN

Masked hypertension is a risk factor for cardiovascular diseases. However, masked hypertension is sometimes overlooked owing to the requirement for home blood pressure measurements for diagnosing. Mental status influences blood pressure. To reduce undiagnosed masked hypertension, this study assessed the association between depressive symptoms and masked hypertension. This cross-sectional study used data from the Tohoku Medical Megabank Project Community-Based Cohort Study (conducted in Miyagi Prefecture, Japan, from 2013) and included participants with normotension measured at the research center (systolic blood pressure<140 mmHg and diastolic blood pressure <90 mmHg). Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (Japanese version). Masked hypertension was defined as normotension measured at the research center and home hypertension (home systolic blood pressure ≥135 mmHg or home diastolic blood pressure ≥85 mmHg). The study comprised 6705 participants (mean age: 55.7 ± 13.7 years). Of these participants, 1106 (22.1%) without depressive symptoms and 393 (23.2%) with depressive symptoms were categorized to have masked hypertension. Sex-specific and age-adjusted least mean squares for home blood pressure, not for research blood pressure were significantly higher in the group with depressive symptoms in both sex categories. The multivariate odds ratio for masked hypertension in the patients with depressive symptoms was 1.72 (95% confidence interval: 1.26-2.34) in male participants and 1.30 (95% confidence interval: 1.06-1.59) in female ones. Depressive symptoms were associated with masked hypertension in individuals with normotension measured at the research center. Depressive symptoms may be one of the risk factors for masked hypertension. Depressive symptoms were associated with masked hypertension in individuals with normotension measured at research center.

RESUMEN

BACKGROUND: Hypertensive disorders in pregnancy and other adverse pregnancy outcomes (APOs) increase the risk of developing chronic hypertension and cardiovascular disease. Perceptions of stress and neighborhood context also influence blood pressure (BP) fluctuations. We examined if APOs, higher perceived stress, and neighborhood deprivation were associated with hypertension phenotypes a decade after pregnancy in untreated individuals. METHODS: Participants were 360 individuals who gave birth between 2008 and 2009 and participated in a research study 8-10 years following pregnancy. Standardized office and home BP readings were obtained, and we applied the AHA/ACC 2017 guidelines to identify sustained, white coat, and masked hypertension phenotypes. We measured personal stress with the perceived stress scale and neighborhood deprivation with the CDC Social Vulnerability Index. RESULTS: Of the 38.3% (138/360) with any hypertension, 26.1% (36/138) reported a diagnosis of hypertension but were currently untreated. Sustained hypertension was the most common (17.8%), followed by masked and white coat hypertension, both 10.3%. Hypertensive disorders in pregnancy were associated with sustained (odds ratio [OR] 5.54 [95% confidence interval, CI 2.46, 12.46] and white coat phenotypes (OR 4.20 [1.66, 10.60], but not masked hypertension (OR 1.74 [0.62, 4.90]). Giving birth to a small for gestational age infant was also associated with sustained hypertension. In covariate adjusted models, perceived stress, but not neighborhood deprivation, was significantly associated with masked hypertension. CONCLUSIONS: A decade after delivery, APOs were associated with sustained and white coat hypertension, but not masked hypertension. Exploration of the mechanisms underlying, and clinical implications of, these associations is warranted.

RESUMEN

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 ±â€…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.

RESUMEN

To analyze the relationship between the level of BP achieved with treatment and the risk for development of preeclampsia/eclampsia (PE), we conducted a historical cohort study on 149 consecutive pregnant women with treated chronic hypertension, evaluated between January 1, 2016, and November 31, 2022. According to office BP readings and ambulatory blood pressure monitoring (ABPM) performed after 20 weeks of gestation, the cohort was classified in controlled hypertension, white-coat uncontrolled hypertension, masked uncontrolled hypertension and sustained hypertension. Risks for the development of PE were estimated using logistic regression. One hundred and twenty-four pregnant women with a control BP evaluation were included in this analysis. The rates of PE were 19.4%, 27.3%, 44.8% and 47.1% for controlled, white-coat uncontrolled, masked uncontrolled and sustained uncontrolled hypertension, respectively. Compared with women with controlled hypertension, the relative risk for PE increased markedly in women with sustained uncontrolled (OR 3.69, 95% CI, 1.19-11.45) and masked uncontrolled (OR 3.38, 95% CI, 1.30-11.45) hypertension, but not in those with white-coat uncontrolled (OR 1.56 95% CI, 0.36-6.70); adjustment for covariates did not modify the results. Each mmHg higher of systolic and diastolic daytime ABPM increased the relative risk for PE ~4% and ~5%, respectively. Each mmHg higher of systolic and diastolic nocturnal BP increased the risk ~5% and ~6%, respectively. When these risks were adjusted for ABPM values in opposite periods of the day, only nocturnal ABPM remained as a significant predictor. In conclusion, masked uncontrolled hypertension implies a substantial risk for the development of PE, comparable to those of sustained uncontrolled. The presence of nocturnal hypertension seems important.
