Abstract
BACKGROUND Primary hypertension in childhood tracks into adulthood and may be associated with increased cardiovascular risk. Studies conducted in children and adolescents provide an opportunity to explore the early cardiovascular target organ injury (CV-TOI) in a population free from many of the comorbid cardiovascular disease risk factors that confound studies in adults. METHODS Youths (n=132, mean age 15.8 years) were stratified by blood pressure (BP) as low, elevated, and high-BP and by left ventricular mass index (LVMI) as low- and high-LVMI. Systemic circulating RNA, miRNA, and methylation profiles in peripheral blood mononuclear cells and deep proteome profiles in serum were determined using high-throughput sequencing techniques. RESULTS VASH1 gene expression was elevated in youths with high-BP with and without high-LVMI. VASH1 expression levels positively correlated with systolic BP (r=0.3143, p=0.0034). The expression of hsa-miR-335-5p, one of the VASH1-predicted miRNAs, was downregulated in high-BP with high-LVMI youths and was inversely correlated with systolic BP (r=-0.1891, p=0.0489). GSE1 hypermethylation, circulating PROZ upregulation (log2FC=0.61, p=0.0049 and log2FC=0.62, p=0.0064), and SOD3 downregulation (log2FC=-0.70, p=0.0042 and log2FC=-0.64, p=0.010) were observed in youths with elevated BP and high-BP with high-LVMI. Comparing the transcriptomic and proteomic profiles revealed elevated HYAL1 levels in youths displaying high-BP and high-LVMI. CONCLUSIONS The findings are compatible with a novel blood pressure-associated mechanism that may occur through impaired angiogenesis and extracellular matrix degradation through dysregulation of Vasohibin-1 and Hyaluronidase1 was identified as a possible mediator of CV-TOI in youth with high-BP and suggests strategies for ameliorating TOI in adult-onset primary hypertension.

Abstract
BACKGROUND This is the first study to report on the impact of race on differences in the prevalence of echocardiographic left ventricular hypertrophy and left ventricular adaptation at the time of diagnosis of essential hypertension in children. METHODS This cross-sectional, single-centre study included patients aged 3-18 years who had newly diagnosed essential hypertension. Echocardiography was used to assess left ventricular mass index and left ventricular relative wall thickness. An left ventricular mass index > the 95th percentile for age and gender, and an left ventricular relative wall thickness > 0.42, were used to diagnose left ventricular hypertrophy and concentric adaptation. Various echocardiographic parameters were compared between African Americans and Caucasians. RESULTS The study included 422 patients (289 African Americans and 133 Caucasians) diagnosed with essential hypertension at a median age of 14.6 (interquartile range; 12.1-16.3) years. Eighty-eight patients (20.9%) had left ventricular hypertrophy. There was no statistically significant difference in the prevalence of left ventricular hypertrophy between African Americans and Caucasians (22.5% versus 17.3%, p=0.22). The median left ventricular relative wall thickness was 0.35 (0.29-0.43), and 114 patients (27.0%) had an left ventricular relative wall thickness > 0.42. The presence of an left ventricular relative wall thickness > 0.42 was significantly higher among African Americans compared to Caucasians (30.1% versus 20.3%, p = 0.04). The African American race was a strong predictor for an left ventricular relative wall thickness > 0.42 (odds ratio 1.7, p = 0.04), but not for left ventricular mass index > the 95th percentile (p = 0.22). Overweight/obesity was a strong predictor for an left ventricular mass index > the 95th percentile. CONCLUSIONS There was no difference in the prevalence of left ventricular hypertrophy in children with essential hypertension of different races. Obesity, rather than being African American, is associated with left ventricular hypertrophy.

J Hum Hypertens 2024; 38:238-244. [PMID: 38114720 DOI: 10.1038/s41371-023-00883-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 11/27/2023] [Accepted: 12/06/2023] [Indexed: 12/21/2023]
Abstract
The spot urinary sodium-to-potassium (Na/K) ratio is a simple measure of salt loading and has been shown to be associated with elevated blood pressure (BP) in middle-aged and older adults. This study aimed to evaluate the association between the spot urinary Na/K ratio and BP in 457 healthy adolescents aged 12-15 years in a school-based setting. The mean urinary Na/K ratio was 4.99 ± 2.76, and no significant difference was found between the boys and girls. When the participants were stratified based on urinary Na/K ratio quartile, age- and sex-adjusted systolic and diastolic BP gradually increased as Na/K ratio increased (systolic BP: 106.1, 106.9, 108.2, and 111.5 mmHg, Ptrend < 0.001; diastolic BP: 62.0, 62.4, 63.1, 64.3 mmHg, Ptrend = 0.022). The systolic and diastolic BP were more closely associated with urinary Na/K ratio than with Na and K levels, as well as estimated daily salt intake. In the multiple regression analysis, the urinary Na/K ratio was significantly associated with systolic BP (β = 0.144, P < 0.001) and diastolic BP (β = 0.114, P = 0.015) independent of potential confounding factors. An additional subgroup analysis revealed that the BP of the group with both high salt intake (≥8.5 g/day) and high Na/K ratio (≥6.60) was significantly higher than that of the group with high salt intake alone (systolic BP, 115.0 vs. 109.1 mmHg, P < 0.001; diastolic BP, 66.0 vs. 62.5 mmHg, P = 0.017). These results suggest that the urinary Na/K ratio is associated with BP levels in healthy adolescents and may be useful for assessing salt loading and its effects on BP elevation.

Abstract
BACKGROUND Current recommendations regarding the utility of diagnostic investigations for pediatric hypertension are based on limited evidence, leading to wide practice variation. The objective of this study was to characterize the cohort of children that may benefit from secondary hypertension workup, and determine the diagnostic yield of investigations. METHODS This was a single-center, retrospective cohort study of 169 children aged 1-18 years referred between 2000 and 2015, to a tertiary pediatric nephrology center in Canada, for evaluation of hypertension. The number of investigations completed, abnormal findings, and diagnostic findings that helped establish hypertension etiology was determined. RESULTS 56 children were diagnosed with primary and 72 children with secondary hypertension in the outpatient setting. Secondary hypertension was predominant at all ages except for obese adolescents ≥ 12 years. Half of children with traditional risk factors for primary hypertension, including obesity, were diagnosed with secondary hypertension. Kidney ultrasound had the highest yield of diagnostic results (19.8%), with no difference in yield between age groups (P = 0.19). Lipid profile had a high yield of abnormal results (25.4%) as part of cardiovascular risk assessment but was only abnormal in overweight/obese children. Echocardiogram had a high yield for identification of target-organ effects in hypertensive children (33.3%). CONCLUSION A simplified secondary hypertension workup should be considered for all hypertensive children and adolescents. High yield investigations include a kidney ultrasound, lipid profile for overweight/obese children, and echocardiograms for assessment of target-organ damage. Further testing could be considered based on results of initial investigations for the most cost-effective management.

Abstract
BACKGROUND Hypertension acquired in paediatric critical patients is a recognised challenge, with variable reported frequency. Pain, agitation, and/or medications such as beta stimulants and corticosteroids are well-known risk factors. Sympathomimetics in septic patients can cause high blood pressure, especially with unobserved haemodynamic monitors. Beyond haemodynamic factors, several endocrinal-metabolic factors - including catecholamines, insulin, renin, angiotensin, the aldosterone system, and sodium consumption - may contribute to the left ventricular growth. It is well known that the sympathetic tone has a trophic effect on the heart muscle. METHOD A prospective cohort study was conducted during the year 2021. The children were divided into two groups: those who were critically ill with paediatric intensive care unit-acquired hypertension (n = 59) and those without paediatric intensive care unit-acquired hypertension (n = 62). We used the American Academy of Pediatrics' 2017 definition of hypertension to diagnose paediatric intensive care unit-acquired hypertension. Measurement of cardiac output and systemic vascular resistance was performed by cardiometry. Left ventricular myocardial performance and left ventricular mass index were measured by bedside echocardiography at the onset of hypertension diagnosis. RESULTS Critically ill children with acquired hypertension had a higher cardiac index (p = 0.0001), systemic vascular resistance index (<0.0001), myocardial performance (0.037), and left ventricular mass index (0.009). The longer duration of stay observed in the hypertension group had no observable effect on mortality (<0.0001). CONCLUSION Both myocardial performance and left ventricle mass index increased in critically ill children with paediatric intensive care unit-acquired hypertension.

Body Mass Index (BMI) Is the Strongest Predictor of Systemic Hypertension and Cardiac Mass in a Cohort of Children. Nutrients 2023; 15:5079.

Abstract
BACKGROUND Hypertension (HTN) is a well-established cardiovascular (CV) risk factor in adults. The presence of HTN in children appears to predict its persistence into adulthood. Early diagnosis of HTN is crucial to reduce CV morbidity before the onset of organ damage. AIM The aim of this study is to investigate cardiac damage in HTN, its risk factors (RFs), and evolution. METHODS We conducted a prospective/retrospective study involving children referred to the Childhood Hypertension Outpatient Clinic. This study included clinical and echocardiographic assessments of cardiac morphology and function at three time points: enrollment (T0) and follow-up (T1 and T2). RESULTS Ninety-two patients (mean age 11.4 ± 3 years) were enrolled. Cardiac eccentric and concentric hypertrophy were present in 17.9% and 9%, respectively, with remodeling in 10.5%. Overweight/obese subjects exhibited significantly higher systolic blood pressure (SBP), frequency of HTN, and body mass index (BMI) at T0 compared with patients with chronic kidney disease (CKD). SBP and BMI persisted more during follow-up. Normal-weight vs. overweight/obese patients were significantly more likely to have normal geometry. Positive correlations were found between BMI and left ventricular (LV) mass at T0, BMI and SBP at T0 and T1. Gender, BMI, SBP, and diastolic blood pressure (DBP) significantly predicted LV mass index (LVMI), but only BMI added significance to the prediction. During follow-up, the variation of BMI positively correlated with the variation of SBP, but not with LVMI. CONCLUSIONS In our cohort, body weight is strongly associated with HTN and cardiac mass. Importantly, the variation in body weight has a more significant impact on the consensual variation of cardiac mass than blood pressure (BP) values. A strict intervention on weight control through diet and a healthy lifestyle from early ages might reduce the burden of CV morbidity in later years.

Abstract
Autosomal dominant (ADPKD) and autosomal recessive (ARPKD) polycystic kidney disease are the most widely known cystic kidney diseases. They are significantly different from each other in terms of genetics and clinical manifestations. Hypertension is one of the main symptoms in both diseases, but the age of onset and secondary cardiovascular complications are significantly different. Most ARPKD children are hypertensive in the first year of life and need high doses of hypertensive drugs. ADPKD patients with a very early onset of the disease (VEOADPKD) develop hypertension similarly to patients with ARPKD. Conversely, a significantly lower percentage of patients with classic forms of ADPKD develops hypertension during childhood, although probably more than originally thought. Data published in the past decades show that about 20%–30% of ADPKD children are hypertensive. Development of hypertension before 35 years of age is a known risk factor for more severe disease in adulthood. The consequences of hypertension on cardiac geometry and function are not well documented in ARPKD due to the rarity of the disease, the difficulties in collecting homogeneous data, and differences in the type of parameters evaluated in different studies. Overall, left ventricular hypertrophy (LVH) has been reported in 20%–30% of patients and does not always correlate with hypertension. Conversely, cardiac geometry and cardiac function are preserved in the vast majority of hypertensive ADPKD children, even in patients with faster decline of kidney function. This is probably related to delayed onset of hypertension in ADPKD, compared to ARPKD. Systematic screening of hypertension and monitoring secondary cardiovascular damage during childhood allows initiating and adapting antihypertensive treatment early in the course of the disease, and may limit disease burden later in adulthood.

Abstract
Beginning in the 1970s, hypertension in children and adolescents has been defined as systolic and/or diastolic blood pressure (BP) that is equal to or greater than the 95th percentile of the normal BP distribution in healthy children. The definition of hypertension in adults is based on longitudinal data that links a BP level with an increased risk for subsequent adverse outcomes related to hypertension including heart failure, kidney failure, stroke, or death. The statistical definition of hypertension continues to be used in childhood because there have been no data that link a BP level in childhood with a heightened risk for adverse outcomes in adulthood. Findings from clinical and epidemiologic research have advanced understanding of high BP in childhood. While hypertension in some children can be secondary to underlying kidney, cardiovascular, or endocrine disorder, it is now known that primary (essential) hypertension can be present in childhood. The prevalence of hypertension in childhood is approximately 2–5% and another 13–18% of children and adolescents have elevated BP and are at heightened risk for developing hypertension. The leading cause of childhood hypertension is primary hypertension, especially in adolescents. For children and adolescents with secondary hypertension, the treatment can focus on managing the underlying cause of hypertension. Less is known about managing primary hypertension in childhood, including diagnosis, evaluation, treatment, and possibilities for prevention. The phenotype of primary hypertension in childhood and recent findings will be discussed.

Abstract
PURPOSE OF REVIEW To review target organ outcomes and current pharmacologic treatment options for children and adolescents with hypertension. RECENT FINDINGS There is an increased prevalence of pediatric hypertension. Following the 2017 AAP clinical practice guidelines, there is a growing body of literature illustrating the association between pediatric hypertension and end organ damage, though few studies looking at long-term outcomes. There is also new data to support the use of n-of-1 trials to identify the best antihypertensive therapy for an individual. Pediatric hypertension is increasing in prevalence and is associated with end organ damage. Treatment of hypertensive children has been shown to reverse end organ damage. Due to the lack of large, randomized trials assessing antihypertensive classes against one another, n-of-1 studies may serve as a viable and safe option to optimize patient care.

Abstract
BACKGROUND Left ventricular hypertrophy (LVH) is the main marker of HMOD in children and young people (CYP). We aimed to assess the prevalence of LVH and its determinants in CYP with primary hypertension (PH). METHODS A meta-analysis of prevalence was performed. A literature search of articles reporting LVH in CYP with PH was conducted in Medline, Embase, and Cochrane databases. Studies with a primary focus on CYP (up to 21 years) with PH were included. Meta-regression was used to analyze factors explaining observed heterogeneity. RESULTS The search yielded a total of 2,200 articles, 153 of those underwent full-text review, and 47 reports were included. The reports evaluated 51 study cohorts including 5,622 individuals, 73% male subjects, and a mean age of 13.6 years. LVH was defined as left ventricle mass index (LVMI) ≥ 95th percentile in 22 (47%), fixed cut-off ≥38.6 g/m2.7 in eight (17%), sex-specific fixed cut-off values in six (13%), and miscellaneously in others. The overall prevalence of LVH was 30.5% (95% CI 27.2-33.9), while heterogeneity was high (I 2 = 84%). Subgroup analysis including 1,393 individuals (76% male subjects, mean age 14.7 years) from pediatric hypertension specialty clinics and LVH defined as LVMI ≥95th percentile only (19 study cohorts from 18 studies), reported prevalence of LVH at 29.9% (95% CI 23.9 to 36.3), and high heterogeneity (I 2 = 84%). Two studies involving patients identified through community screening (n = 1,234) reported lower LVH prevalence (21.5%). In the meta-regression, only body mass index (BMI) z-score was significantly associated with LVH prevalence (estimate 0.23, 95% CI 0.08-0.39, p = 0.004) and accounted for 41% of observed heterogeneity, but not age, male percentage, BMI, or waist circumference z-score. The predominant LVH phenotype was eccentric LVH in patients from specialty clinics (prevalence of 22% in seven studies with 779 participants) and one community screening study reported the predominance of concentric LVH (12%). CONCLUSION Left ventricular hypertrophy is evident in at least one-fifth of children and young adults with PH and in nearly a third of those referred to specialty clinics with a predominant eccentric LVH pattern in the latter. Increased BMI is the most significant risk association for LVH in hypertensive youth.

Abstract
BACKGROUND Unlike in adults, there are limited pediatric data exploring the association between acute respiratory illnesses and blood pressure abnormalities. The aim of our study was to explore the association of bronchiolitis, a common respiratory illness, with elevated blood pressure in hospitalized children. METHODS In this single center retrospective case-control study, we evaluated the association between bronchiolitis and elevated blood pressure and hypertension in hospitalized children, compared to a control group admitted with nonrespiratory conditions, using multivariate regression analyses. Standard published normative data on pediatric blood pressure were used to classify children in various blood pressure categories. RESULTS A high prevalence of elevated blood pressure (16%) and hypertension (60%) was noted among children with bronchiolitis; this was not statistically different from the control group (18% for elevated blood pressure; 57% for hypertension; P-values, 0.71 and 0.53, respectively). On multivariate regression analyses, only length of stay was associated with hypertension. No patient with blood pressure abnormalities received antihypertensives nor were any nephrology consults documented. CONCLUSIONS A high prevalence of blood pressure abnormalities, without documentation of their recognition, was noted in hospitalized children regardless of diagnosis, pointing to the need for more data on outcomes-driven significance of pediatric inpatient blood pressure measurements.

Abstract
OBJECTIVE We aimed to evaluate the effects of blood pressure (BP) values obtained by 24-h ambulatory BP monitoring (ABPM) of hypertensive children and adolescents on left ventricular mass index (LVMI). METHODS Patients diagnosed with HT with BP measurements confirmed with ABPM and evaluated with echocardiography for LVMI were included. The patients were divided into two groups according to their BMI as obese and nonobese. SDSs of ABPM parameters were compared between the groups. RESULTS A total of 158 children with HT were included in the study. Ninety of these patients were obese. In obese and nonobese cases, mean SDS levels were similar in ABPM parameters, whereas LVMI was significantly higher in obese patients ( P = 0.049). There was a significant correlation between LVMI and 24-h SBP SDS, daytime SBP SDS, 24-h SBP load and daytime BP load. In obese cases, there was a statistically significant correlation between LVMI and 24-h SBP SDS, daytime SBP SDS, 24-h SBP load, daytime SBP load as well as nighttime SBP SDS and nighttime SBP load. When the whole group was evaluated, 24-h SBP SDS was the most effective parameter influencing LVMI ( P = 0.001). Similarly, the most effective ABPM parameter on LVMI in obese patients was 24-h SBP SDS ( P = 0.001). CONCLUSION A significantly higher rate of LVMI in obese patients suggests that obesity itself is an effective factor on LVMI. In addition, systolic hypertension is more effective on cardiac functions compared with DBP measurements and systolic-DBP dipping ratios.

Abstract
OBJECTIVE To investigate the relative contributions of obesity and obstructive sleep apnea (OSA) to unfavorable blood pressure in children. STUDY DESIGN Children aged 3-18 years with OSA-related symptoms were recruited. All children underwent office blood pressure (BP) monitoring and full-night polysomnography. Obesity was defined as a body mass index ≥95th percentile. OSA severity was divided into primary snoring (apnea-hypopnea index [AHI] <1), mild OSA (5> AHI ≥1), and moderate to severe OSA (AHI ≥5). Age- and sex-adjusted logistic regression analysis was performed to determine the associations among OSA, obesity, and elevated BP. RESULTS This cross-sectional study enrolled 1689 children (66% boys), with a mean age of 7.9 years. Compared with children with primary snoring, children with moderate to severe OSA had significantly higher systolic BP (108.1 mmHg vs 105.6 mmHg), diastolic BP (75.0 mmHg vs 70.4 mmHg), systolic BP percentile (75.0 vs 70.4), and diastolic BP percentile (74.0 vs 69.2). The rate of unfavorable BP (ie, elevated BP or hypertension level BP) also was significantly higher in children with more severe OSA. Children with obesity had higher BP and BP percentile. Logistic regression analysis revealed that children with obesity and moderate to severe OSA have a 3-fold greater risk of unfavorable BP compared with children without obesity and primary snoring. CONCLUSIONS We identified a 3-fold greater risk of unfavorable BP in children with obesity and moderate to severe OSA.

Abstract
A follow-up data on electrocardiogram (ECG) and blood pressure (BP) changes in adolescent athletes are scarce. We compared ECG and BP between adolescent athletes and non-athletes in a 4-year follow-up. A total of 154 youth sports clubs (SC) in Finland and 100 secondary schools for comparison data participated in this observational follow-up study. Those who maintained or adopted SC participation are referred to as "Always athletes" (n=137), those who never participated in SC as "Never athletes" (n=108) and those who dropped out of SC during the follow-up as "Changers" (n=116). The mean age of the participants was 15.5 (0.6) years in all study groups at baseline. Resting ECG including heart rate, PR interval, QRS duration, QRS axis, QRS amplitude, T axis and QT interval and BP were measured from all participants at baseline and after follow-up. "Always athletes" had lower resting heart rate, more negative T-wave axis and higher QRS amplitude than "Never athletes" at baseline and at 4-years (P < 0.05). "Changers" had lower resting heart rate, more negative T-wave axis and higher QRS amplitude, systolic BP and pulse pressure than "Never athletes" at baseline (P < 0.05). None of the observed differences at baseline, were visible at 4-years (P > 0.05) except the difference in T-wave axis (P = 0.028). The significant group x time interaction between "Changers" and "Never athletes" was found for QRS amplitude (P = 0.017). Adolescent athletes have several training-induced cardiovascular adaptations, which return towards the levels of non-athletes after cessation of regular training.

Abstract
PURPOSE OF REVIEW The prevalence of hypertension in adolescents and young adults has increased in part due to the obesity epidemic. The clinical impact and future cardiovascular risk of this underestimated public health problem is an evolving field. RECENT FINDINGS The development of hypertension is predicted by tracking of elevated blood pressure from childhood to adulthood. Young hypertensive individuals have lower awareness, slower diagnosis rates, and poorer blood pressure control than older patients. Increased awareness, appropriate screening, early identification, and individualized treatment approaches for elevated blood pressure could prevent development of hypertension in adulthood and cardiovascular events in later life. The optimal blood pressure management for young adults with a low 10-year risk of atherosclerotic cardiovascular disease of < 10% remains challenging due to lack of randomized controlled trials. Evidence-based recommendations are needed to implement appropriate measures for time of treatment initiation, preferred antihypertensive drug class to be used and optimal target blood pressure level from childhood through young adulthood.

Abstract
OBJECTIVE To assess prevalence of and factors associated with left ventricular diastolic dysfunction (LVDD) in youth with obesity and elevated blood pressure (BP). STUDY DESIGN This was a cross-sectional analysis of baseline and follow-up visits of 83 youth, 5-21 years, evaluated for overweight/obesity and elevated BP in a multidisciplinary clinic. LVDD was defined according to established adult criteria (LVDDadult; E/A < 1, E/e' > 14, or e'/a' < 0.8) and pediatric criteria (LVDDpeds; E/A <10th percentile, E/e' >99th percentile, or e'/a' <1st percentile) based on data from 103 age-sex matched healthy controls. Baseline factors associated with LVDDpeds were examined using Wilcoxon rank sum and χ2 tests. Multiple logistic regression analyses using generalized estimating equations to account for repeated measures evaluated the associations of adiposity and BP with LVDDpeds. RESULTS The prevalence of LVDD ranged from 1.2% to 2.7% when we used adult criteria and 19% to 28% when we used pediatric criteria. Those with LVDDpeds were older, predominantly male, and non-African American and had greater weight, BP, BP medication use, and non-high-density lipoprotein cholesterol than those without LVDDpeds. Diastolic BP z score was associated with LVDDpeds by E/A (OR 1.95, 95% CI 1.15-3.32, P = .014) after we adjusted for age, sex, race, BP medications, and body mass index z score. CONCLUSIONS LVDD was present in a substantial proportion of youth with overweight/obesity and elevated BP using pediatric criteria. Those with LVDDpeds had significantly greater measures of adiposity and BP compared with those without LVDDpeds, and diastolic BP z score was an independent predictor of LVDDpeds by E/A. These data emphasize the importance of prevention and treatment of cardiovascular disease risk factors in childhood.

Abstract
Extensive evidence shows that risk factors for cardiovascular disease (CVD) begin to develop early in life. Childhood obesity and elevated blood pressure (BP) have become overwhelmingly challenging, with 57% of today's children predicted to be obese by the age of 35 years, and global rates of hypertension in children and adolescents increasing by 75% from 2000 to 2015. Thus, there is an urgent need for tools that can assess early CVD risk in youth, which may lead to better risk stratification, preventative intervention, and personalised medicine. Vascular ageing (the deterioration in vascular structure and function) is a pivotal progenitor of health degeneration associated with elevated BP. Exposure to adverse environmental and genetic factors from fetal life promotes the development and accumulation of subclinical vascular changes that direct an individual towards a trajectory of early vascular ageing (EVA)-an independent predictor of target organ damage in the heart, brain, and kidneys. Therefore, characterising vascular ageing from youth may provide a window into cardiovascular risk later in life. However, vascular ageing measurements only have value when techniques are accurate/validated and when reliable thresholds are available for defining normal ranges and ranges that signal increased risk of disease. The aim of this paper is to summarise current evidence on the importance of vascular ageing assessment in youth and the impact of interventions to prevent or delay EVA, to highlight the need for standardisation and validation of measurement techniques in children and adolescents, and the importance of establishing reference values for vascular ageing measures in this population.

Abstract
The prevalence of non-communicable disease (NCDs) is rising globally, with a large burden recorded in sub-Saharan countries and populations of black race/ethnicity. Accelerated vascular deterioration, otherwise known as early vascular aging (EVA), is the underlying factor for highly prevalent NCDs such as hypertension. The etiology of EVA is multifactorial with a central component being arterial stiffness with subsequent development of hypertension and cardiovascular complications. Although arterial stiffness develops with increasing age, many children and adolescents are subjected to the premature development of arterial stiffness, due to genetic or epigenetic predispositions, lifestyle and behavioral risk factors, and early life programming. Race/ethnic differences in pediatric populations have also been reported with higher aortic stiffness in black (African American) compared with age-matched white (European American) counterparts independent of blood pressure, body mass index, or socioeconomic status. With known evidence of race/ethnic differences in EVA, the pathophysiological mechanisms underlying graded differences in the programming of EVA are still sparse and rarely explored. This educational review aims to address the early life determinants of EVA in children and adolescents with a particular focus on racial or ethnic differences.

Abstract
BACKGROUND Hypertension (HTN) is common in children and often associated with pathologic progression to end organ damage, specifically left ventricular hypertrophy (LVH). METHODS The primary goal of this retrospective chart review is to determine if patients with higher blood pressure were more likely to complete echocardiogram (ECHO) and more likely to have LVH, among a pediatric population referred for hypertension evaluation before the 2017 American Academy of Pediatrics (AAP) guidelines. To meet this goal, the number of patients evaluated by ECHO and prevalence of LVH was examined for independent associations with blood pressure and BMI categories by logistic regression. RESULTS It was found that higher blood pressure was associated with having an ECHO evaluation (p = 0.012). Among patients evaluated by ECHO, one-third had LVH but the presence of LVH was not associated with blood pressure severity or use of anti-hypertensive medication. Instead, BMI was the only factor associated with LVH cardiac remodeling in our population (p = 0.025). CONCLUSIONS Newly updated AAP practice guidelines recommend evaluation of HTN via ABPM, with ECHO performed only at the initiation of pharmaceutical therapy. It is notable that BMI, the only risk factor of LVH found in this study, is not addressed in the current AAP guidelines for ECHO evaluation among hypertensive children. This study suggests that ECHO evaluation may be warranted in a larger subset of children as is recommended by current European Society of Hypertension pediatric guidelines.

The concordance of hypertension based on pediatric criteria (American Heart Association 2014) was compared with adult criteria from American College of Cardiology/American Heart Association 2017 (overall BP ≥125/75 mm Hg, wake BP ≥130/80 mm Hg, sleep BP ≥110/65 mm Hg) using the Cohen kappa statistic. Logistic regression, adjusted for body mass index z score, and receiver operating characteristic curves (ROCs) compared pediatric criteria vs adult criteria in predicting LVH (left ventricular mass index >95th percentile reference values and left ventricular mass index >51 g/m2.7). RESULTS Of 306 adolescents, 140 (45.8%) had hypertension based on pediatric criteria vs 228 (74.5%) based on adult criteria; the agreement was poor (59.3%, n = 137, kappa = 0.41). A higher prevalence of LVH was captured by adult criteria only (n = 91) compared with pediatric criteria only (n = 3). Logistic regression found no significant differences between pediatric and adult criteria in the detection of LVH >95th percentile (OR 1.24, CI 0.66, 2.31, P = .51) or >51 g/m2.7 (OR 1.06, CI 0.47, 2.40, P = .89). ROCs for pediatric criteria were not significant for detecting LVH >95th percentile (0.50, P = .91) or >51 g/m2.7 (0.55, P = .45), whereas the ROC for adult criteria was significant for detecting LVH >95th percentile (0.59, P = .045) but not >51 g/m2.7 (0.63, P = .07). Although all individuals with LVH >51 g/m2.7 were hypertensive by adult criteria, 8 of these individuals were missed by pediatric criteria. CONCLUSIONS Adult criteria captured a higher prevalence of LVH and appeared to predict better LVH than pediatric criteria. A consideration to align ABPM criteria for diagnosing hypertension in adolescents with adult guidelines is warranted.

Left Ventricular Geometrical Changes in Severely Obese Adolescents: Prevalence, Determinants, and Clinical Implications. Pediatr Cardiol 2021; 42:331-339. [PMID: 33079265 PMCID: PMC7907012 DOI: 10.1007/s00246-020-02487-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 10/08/2020] [Indexed: 12/17/2022]
Abstract
Left ventricular hypertrophy (LVH) is independently associated with a higher risk of cardiovascular morbidity and mortality in adults. Adiposity is a risk factor for LVH, independent of blood pressure. Potential causes of this nonhemodynamic pathogenesis identified in adults include adverse body fat distribution, insulin resistance, dyslipidemia, and obstructive sleep apnea syndrome (OSA). In severely obese adolescents, the determinants of obesity-induced changes in left ventricular structure are poorly characterized. Cardiac ultrasonographic, demographic, anthropometric, and comorbidity-related data were prospectively collected in adolescents with severe obesity refractory to conservative treatment who presented for surgical therapy. Differences between adolescents with LVH and without LVH were evaluated using independent samples t, chi-square, or Fisher's exact test. Multivariable linear regression analysis was performed to evaluate associations with left ventricular structural changes, corrected for body mass index (BMI) z score. Forty-three patients entered analysis, of whom 24 (55.8%) showed LVH. The most common geometrical change was eccentric LVH (eLVH), occurring in 21 subjects (48.8%). Demographic and anthropometric variables did not differ between patients with and without LVH. Independent of BMI z score, left ventricular mass index was significantly associated with apnea-hypopnea index (AHI) (regression parameter B = 0.8; 95% CI 0.3 to 1.2). Interventricular septum thickness (IVST) was significantly associated with HOMA-IR values (B = 0.1; 95% CI 0.04 to 0.2), HDL-cholesterol (B = - 1.2; 95% CI - 2.2 to 0.1), and triglyceride levels (B = 0.5; 95% CI 0.001 to 0.9). LVH, especially eLVH, is highly prevalent amongst severely obese adolescents. Adverse changes in cardiac structure, increased IVST in particular, are independently associated with several nonhemodynamic comorbidities that are common in this population, namely OSA, insulin resistance, and dyslipidemia.

Abstract
Clinical practice guidelines for diagnosis and management of pediatric hypertension have been available for decades. Yet, most cases of hypertension in children are undiagnosed. Provider and system-based factors, such as the complexity of diagnostic standards, and a failure among physicians to recognize the importance of hypertension in children, play a role in underdiagnosis. It is unclear, however, how patient and family behaviors impact the diagnosis and treatment of pediatric hypertension. We aimed to explore the perspectives of parents whose children have had multiple high blood pressure readings or have been diagnosed with hypertension to inform clinicians with areas for practice improvement. In a 2 site qualitative study, we interviewed parents of 15 children diagnosed with hypertension. Results from semi-structured interviews with parents revealed barriers to the diagnosis of pediatric hypertension, including uncertainty about the diagnosis and concerns around the accuracy of blood pressure measurements. Delay in diagnosis and lack of child engagement emerged as obstacles to the treatment of pediatric hypertension.

Abstract
IMPORTANCE Childhood hypertension can result in adverse outcomes during adulthood; identifying and treating primary and secondary childhood hypertension may reduce such risks. OBJECTIVE To update the evidence on screening and treatment of hypertension in childhood and adolescence for the US Preventive Services Task Force. DATA SOURCES PubMed, Cochrane Library, International Pharmaceutical Abstracts, EMBASE, and trial registries through September 3, 2019; bibliographies from retrieved articles, experts, and surveillance of the literature through October 6, 2020. STUDY SELECTION Fair- or good-quality English-language studies evaluating diagnostic accuracy of blood pressure screening; cohort studies assessing the association of hypertension in childhood and adolescence with blood pressure or other intermediate outcomes in adulthood; randomized clinical trials (RCTs) or meta-analyses of pharmacological and lifestyle interventions. DATA EXTRACTION AND SYNTHESIS Two reviewers independently assessed titles/abstracts and full-text articles, extracted data, and assessed study quality; the evidence was synthesized qualitatively. MAIN OUTCOMES AND MEASURES Sensitivity, specificity, and measures of association between childhood and adulthood blood pressure; reduction of childhood blood pressure; adverse effects of treatments. RESULTS Forty-two studies from 43 publications were included (N>12 400). No studies evaluated the benefits or harms of screening and the effect of treating childhood hypertension on outcomes in adulthood. One study reported a sensitivity of 0.82 and a specificity of 0.70 for 2 office-based blood pressure measurements. Twenty observational studies suggested a significant association between childhood hypertension and abnormal blood pressure in adulthood (odds ratios, 1.1-4.5; risk ratios, 1.45-3.60; hazard ratios, 2.8-3.2). Thirteen placebo-controlled RCTs and 1 meta-analysis assessed reductions in systolic (SBP) and diastolic blood pressure from pharmacological treatments. Pooled reductions of SBP were -4.38 mm Hg (95% CI, -7.27 to -2.16) for angiotensin-converting enzyme inhibitors and -3.07 mm Hg (95% CI, -4.99 to -1.44) for angiotensin receptor blockers. Candesartan reduced SBP by -6.56 mm Hg (P < .001; n = 240). β-Blockers, calcium channel blockers, and mineralocorticoid receptor antagonists did not achieve significant reductions over 2 to 4 weeks. SBP was significantly reduced by exercise over 8 months (-4.9 mm Hg, P ≤ .05; n = 69), by dietary approaches to stop hypertension over 3 months (-2.2 mm Hg, P < .01; n = 57), and by a combination of drug treatment and lifestyle interventions over 6 months (-7.6 mm Hg; P < .001; n = 95). Low-salt diet did not achieve reductions of blood pressure. CONCLUSIONS AND RELEVANCE Observational studies indicate an association between hypertension in childhood and hypertension in adulthood. However, the evidence is inconclusive whether the diagnostic accuracy of blood pressure measurements is adequate for screening asymptomatic children and adolescents in primary care.

Abstract
RATIONALE & OBJECTIVE Traditional and nontraditional cardiovascular disease risk factors are highly prevalent in children with chronic kidney disease (CKD). We examined the longitudinal association of adiposity with cardiac damage among children with CKD and explored whether this association was modified by sex. STUDY DESIGN Prospective cohort study. SETTING & PARTICIPANTS Children with mild-to-moderate CKD enrolled in the Chronic Kidney Disease in Children (CKiD) Study at 49 pediatric nephrology centers across North America. EXPOSURE Age- and sex-specific body mass index (BMI) z score. OUTCOME Age- and sex-specific left ventricular mass index (LVMI) z score and left ventricular hypertrophy (LVH). ANALYTICAL APPROACH Longitudinal analyses using mixed-effects models to estimate sex-specific associations of BMI z scores with LVMI z score and with LVH, accounting for repeated measurements over time. RESULTS Among 725 children with 2,829 person-years of follow-up, median age was 11.0 years and median estimated glomerular filtration rate was 52.6mL/min/1.73m2. Nearly one-third of both boys and girls were overweight or obese, median LVMI z score was 0.18 (IQR: -0.67, 1.08), and 11% had LVH. Greater BMI z scores were independently associated with greater LVMI z scores and greater odds of LVH. For each 1-unit higher BMI z score, LVMI z score was 0.24 (95% CI, 0.17-0.31) higher in boys and 0.38 (95% CI, 0.29-0.47) higher in girls (Pinteraction = 0.01). For each 1-unit higher BMI z score, the odds of LVH was 1.5-fold (95% CI, 1.1-2.1) higher in boys and 3.1-fold (95% CI, 1.8-4.4) higher in girls (Pinteraction = 0.005). LIMITATIONS Not all children had repeated measurements. LVH is a surrogate and not a hard cardiac outcome. The observational design limits causal inference. CONCLUSIONS In children, adiposity is independently associated with the markers of cardiac damage, LVMI z score and LVH. This association is stronger among girls than boys. Pediatric overweight and obesity may therefore have a substantial impact on cardiovascular risk among children with CKD.

Abstract
The ultimate goal of recognizing and treating hypertension in childhood is to prevent target-organ damage during childhood and to reduce the risk of adulthood cardiovascular disease. The quality of evidence to guide blood pressure management in children is lower than in adult medicine, yet some common findings support clinical practice recommendations. Oscillometric devices are increasingly replacing manual blood pressure measurements, but evidence shows that readings are not equivalent between the 2 methods. In addition, multiple blood pressure readings are needed before diagnosing a child with hypertension, but the optimal number and timing are still being determined. The recent American Academy of Pediatrics blood pressure guideline has revised the normative data tables and included threshold blood pressure limits which seem to identify children with higher cardiovascular risks. Threshold limits vary between guidelines, and the most accurate threshold has yet to be determined. Lifestyle modifications are a cornerstone of hypertension management, but the optimal diet and physical activity changes for beneficial effect are not known. When pharmacotherapy is needed, physicians have used drugs from all antihypertensive classes in children, yet only a few classes have been systematically studied. The long-term cardiovascular consequences of elevated blood pressure during childhood are under investigation and it seems that the lower the childhood blood pressure the better and that the rate of change during childhood is predictive of adulthood disease. With much still to learn, this article summarizes the evidence and the evidence gaps for the diagnosis, investigation, management, and outcomes of pediatric hypertension.

Abstract
BACKGROUND Childhood hypertension (CH) is related to the dietary intake and diversity of children. The study aimed to assess the critical role of dietary diversity, and seafood long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs) in reducing CH among the Iranian community. METHODS A cross-sectional two-phase study with 7-12-year-old Iranian students was designed. In the initial phase, the socio-demographic characteristics, and blood pressure status (normal, pre-hypertension, and hypertension) based on systolic (SBP) and diastolic (DBP) blood pressure data were assessed. The 24-h dietary recall questionnaire was used to generate the dietary diversity score (DDS, count of consumed food groups) and dietary variety score (DVS, the cumulative number of daily consumed food items). In the second phase, the association between CH reduction and changes in serum 25-hydroxyvitamin D (25OHD), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides (TG) levels of schoolchildren intervened by a seafood diet rich in omega-3 fatty acids were assessed using the regression analyses. RESULTS The pre-hypertension and hypertension prevalence rates were 7.8 and 9.15%, respectively. CH was significantly associated with age, gender, and DDS. A significant inverse association was found between the high intake of seafood and CH (P = 0.032). The gas-chromatography analysis showed the high presence of α-linolenic (ALA, 6.72%), eicosapentaenoic (EPA, 7.62%), docosapentaenoic (DPA, 5.88%), and docosahexaenoic (DHA, 18.52%) acids in the seafood-based diet (p < 0.05). The low blood pressure levels with regular consumption of this healthy-functional diet were significantly associated with a reduction in BMI, LDL, TC, and TG, and a remarkable increase in 25OHD and HDL levels. The multiple linear regression showed that the SBP was highly associated with the TC (p < 0.001; β = 0.464). CONCLUSIONS The age and DDS were efficient predictors for the different CH status. A regular seafood-rich dietary pattern due to the high LC n-3 PUFAs contents could significantly reduce the obesity-related cardiovascular risk factors.

Abstract
The assessment by speckle tracking echocardiography (STE) provides useful information on regional and global left ventricular (LV) functions. The aim of the study is to investigate if STE-based strain analysis could detect the difference of pressure overload-induced myocardial remodelling between young and adult rats. Physiological, haemodynamic, histological measurements were performed post-operatively in young and adult rats with transverse aortic constriction (TAC) as well as the age-matched shams. Two-way ANOVA was used to detect the statistical difference of various measured parameters. Pressure overload decreased the ejection fraction, fractional shortening, dp/dtmax and |dp/dtmin|, but increased the LV end-diastolic (ED) pressure in adult rat hearts for nine weeks after TAC operation than those in young rat hearts. Pressure overload also resulted in different changes of peak strain and strain rate in the free wall, but similar changes in the interventricular septum of young and adult rat hearts. The changes in myocardial remodelling were confirmed by the histological analysis including the increased apoptosis rate of myocytes and collagen area ratio in the free wall of adult rat hearts of LV hypertrophy when compared with the young. Pressure overload alters myocardial components in different degrees between young and adult animals. STE-based strain analysis could detect the subtle difference of pressure overload-induced myocardial remodelling between young and adult rats.

Abstract
OBJECTIVE Although an association between moyamoya disease (MMD) and renovascular hypertension has been acknowledged, the literature on systemic hypertension without renal artery stenosis among patients with MMD is scarce. The authors aimed to evaluate the prevalence and risk factors of hypertension using data from MMD patients who visited an outpatient clinic of a pediatric neurosurgical department in 2016. METHODS The authors evaluated the blood pressure (BP) of pediatric MMD patients at their postsurgical appointment following the American Academy of Pediatrics clinical practice guideline on high BP, in which hypertension was defined as BP measurements higher than the value of age-, sex-, and height-specific 95th percentile of the general population from at least 3 separate visits. Growth of patients was determined using 2017 Korean National Growth Charts for children and adolescents. The cutoff value of the 95th percentile of BP was determined by referring to normative BP tables of Korean children and adolescents. A logistic regression model was used to assess the associations between patients' clinical characteristics and prevalent hypertension. RESULTS In total, 131 surgically treated pediatric MMD patients were included, of whom 38.9% were male and the median age at diagnosis was 8.0 years (range 1.2-15.0 years). The definition of hypertension was met in 38 patients, with a prevalence of 29.0% (95% CI 21.2%-36.8%). A tendency was observed for a higher prevalence of hypertension in male patients (31.4%), in patients with posterior cerebral artery (PCA) involvement (47.8%), and in cases in which infarction was shown on initial MRI (37.3%). Age at diagnosis (adjusted OR [aOR] 0.82, 95% CI 0.70-0.97), PCA involvement (aOR 3.81, 95% CI 1.29-11.23), body mass index (aOR 1.30, 95% CI 1.13-1.51), and years of follow-up since surgery (aOR 0.80, 95% CI 0.68-0.94) were related to systemic hypertension. CONCLUSIONS A high prevalence of hypertension was demonstrated in pediatric MMD patients. Therefore, adequate attention should be paid to reduce BP and prevent subsequent events.

Abstract
OBJECTIVE(S) To examine racial differences in the relationship between cardiovascular (CV) risk factors measured since age 10 years and left ventricular mass index (LVMI) in adulthood in the National Heart, Lung, and Blood Institute Growth and Health Study. STUDY DESIGN Longitudinal investigation with CV risk factors measured throughout childhood and LVMI measured in adulthood. In total, 556 black and white girls were recruited from schools in the greater Cincinnati area. Analyses examined traditional CV risk factors at baseline, follow-up, and over time (ie, area under the curve [AUC]). LVMI was collected with 2-dimensional guided echocardiographic imaging at a mean age of 25.7 ± 1.7 years. RESULTS Black girls had higher adiposity and insulin and lower heart rate across time (all P < .05). Blacks had higher LVMI compared with whites in adulthood. Major determinants of young adult LVMI, were race, body mass index z score AUC, systolic blood pressure z score AUC, percent body fat by skin fold AUC, heart rate AUC, and an interaction between race and heart rate (model R2 = 0.40, P < .0001). CONCLUSIONS The major determinants of LVMI in young female adults are race, adiposity, and systolic blood pressure.

These recommendations were systematically developed on behalf of the Network for Early Onset Cystic Kidney Disease (NEOCYST) by an international group of experts in autosomal dominant polycystic kidney disease (ADPKD) from paediatric and adult nephrology, human genetics, paediatric radiology and ethics specialties together with patient representatives. They have been endorsed by the International Pediatric Nephrology Association (IPNA) and the European Society of Paediatric Nephrology (ESPN). For asymptomatic minors at risk of ADPKD, ongoing surveillance (repeated screening for treatable disease manifestations without diagnostic testing) or immediate diagnostic screening are equally valid clinical approaches. Ultrasonography is the current radiological method of choice for screening. Sonographic detection of one or more cysts in an at-risk child is highly suggestive of ADPKD, but a negative scan cannot rule out ADPKD in childhood. Genetic testing is recommended for infants with very-early-onset symptomatic disease and for children with a negative family history and progressive disease. Children with a positive family history and either confirmed or unknown disease status should be monitored for hypertension (preferably by ambulatory blood pressure monitoring) and albuminuria. Currently, vasopressin antagonists should not be offered routinely but off-label use can be considered in selected children. No consensus was reached on the use of statins, but mTOR inhibitors and somatostatin analogues are not recommended. Children with ADPKD should be strongly encouraged to achieve the low dietary salt intake that is recommended for all children.

Abstract
High blood pressure (BP) is becoming a growing health issue even in children and adolescents. Moreover, BP elevation in youth frequently translates into children and adult hypertension contributing to the development of cardiovascular disease. The detection of early markers of vascular damage, potentially leading to overt cardiovascular disease, is important for clinical decisions about if and how to treat hypertension and can be useful in monitoring the effectiveness of the treatment. The purpose of this review is to summarize the actual knowledge about subclinical organ damage (SOD) in hypertensive children and adolescents and its association with cardiovascular disease in children and young adults. Our focus is especially put on left ventricular mass, pulse wave velocity, carotid intima-media thickness and microalbuminuria. We also want to address the scientific evidence about possible regression of SOD and cardiovascular risk with the use of behavioural and specific anti-hypertensive therapy. Indications from current guidelines are critically discussed.

The combination of obesity and high salt intake are associated with blood pressure elevation among healthy Japanese adolescents. J Hum Hypertens 2019; 34:117-124.

Abstract
We examined the associations of obesity and high salt intake with blood pressure (BP) in a cross-sectional sample of 1679 healthy Japanese adolescents (827 females and 852 males) aged 12-18 years (mean age: 14.9 years) who had no history of treatment for hypertension, diabetes mellitus, or renal disease. Brachial arterial BP of the subject was measured at the left arm using a digital BP monitor with an appropriate cuff size. The weight status was evaluated by body mass index (BMI), and obesity was determined according to the age- and sex-specific cut-off values for adolescents. All subjects were interviewed by dietitians using a food frequency questionnaire to obtain data on their average daily salt intake. In the study subjects, obesity and high salt intake were associated with a significantly increased BP except for diastolic BP in females. In multiple regression analyses, both BMI (z-score) and salt intake were found to be major determinants of systolic BP and diastolic BP after adjustment for potential confounders, including age, sex, and serum lipid and glucose parameters. The association between salt intake and BP values was more pronounced among individuals with obesity than among those with normal weight. These results suggest that high salt intake is associated with BP elevation in healthy adolescents, and the association may become stronger by the presence or severity of obesity.

Abstract
Hypertension is associated with left ventricular hypertrophy (LVH), a risk factor for cardiovascular events. Since cardiovascular events in youth are rare, hypertension has historically been defined by the 95th percentile of the normal blood pressure (BP) distribution in healthy children. The optimal BP percentile associated with LVH in youth is unknown. We aimed to determine the association of systolic BP (SBP) percentile, independent of obesity, on left ventricular mass index (LVMI), and to estimate which SBP percentile best predicts LVH in youth. We evaluated SBP, anthropometrics, and echocardiogram in 303 adolescents (mean age 15.6 years, 63% white, 55% male) classified by SBP as low-risk (L=141, <80th percentile), mid-risk (M=71, 80-<90th percentile), or high-risk (H=91, ≥90th percentile) using the mean of 6 measurements at 2 visits according to the 2017 guidelines. Logistic regression was used to determine the sensitivity and specificity of various SBP percentiles associated with LVH. Results: BP groups did not differ by age or demographics but differed slightly by body mass index. Mean BP, LVMI, and prevalence of LVH increased across groups (BP: L=111/75, M=125/82, and H=133/92 mm Hg; LVMI: L=31.2, M=34.2, and H=34.9 g/m2.7; LVH: L=13%, M=21%, H=27%, all P<0.03). SBP percentile remained a significant determinant of LVMI after adjusting for covariates. The 90th percentile for SBP resulted in the best balance between sensitivity and specificity for predicting LVH (LVMI≥38.6 g/m2.7). Abnormalities in cardiac structure in youth can be found at BP levels below those used to define hypertension.

Abstract
Early impairment of left ventricular (LV) function has been reported in some inherited connective tissue diseases such as Marfan syndrome or rheumatic heart disease in pediatric patients. However, there is no study about cardiac strain in pediatric patients with primary mitral valve prolapse (MVP). The aim of this study was to evaluate the LV functions in pediatric patients with primary MVP, mild or moderate mitral regurgitation (MR), and normal LV ejection fraction. The study group included 72 consecutive patients (40 female, mean age: 13.1 ± 5.2 with primary MVP who had mild or moderate MR, and normal systolic function (LV ejection fraction ≥60%) were compared with 40 healthy children using conventional echocardiography, tissue Doppler imaging, and 2-dimensional speckle tracking echocardiography. Patients were divided into subgroups according to the MR severity: mild (n:34), and moderate (n:38) and leaflet thickness: classical (n: 40), and nonclassical (n: 32). The children with MR had significantly lower values for global early diastolic strain rate ([SRe] patients: 1.40 ± 0.25 vs controls: 1.62 ± 0.54; p = 0.001), and E/SRe (patients: 72.7 ± 5.6 vs controls: 62.1 ± 4.9; p <0.04) when compared with the control group. In subgroup analysis, SRe (mild: 1.49 ± 0.38 vs moderate: 1.32 ± 0.31; p <0.001) was lower in MVP patients with moderate MR compared to mild MR, and E/SRe (mild: 69.4 ± 5.1 vs moderate: 75.1 ± 6.4; p <0.001) value was higher in MVP patients with moderate MR compared to mild MR. Diatolic strain parameters, SRe, and E/SRe are more sensitive markers of early subtle myocardial injury in pediatric patients with primary MVP.

Abstract
BACKGROUND There is no detailed strain analysis of cardiac functions in treated hypertensive pediatric patients. The aim of this study was to evaluate the cardio-protective effects of different drug classes in treated pediatric hypertensive patients. METHODS Sixty non-obese-treated hypertensive patients with preserved left ventricular (LV) systolic function and 45 age-, sex-, and body mass index-matched healthy subjects underwent clinical evaluation, including 24-h ambulatory blood pressure monitoring, standard echocardiographic examination, tissue Doppler imaging, and two-dimensional Speckle Tracking Echocardiography. The patients were divided into two subgroups based on the effects of the drugs on the Renin Angiotensin Aldosterone System. The subgroup hypertension (HT) 1 received angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, and HT 2 subgroup received calcium channel blocker, β-blocker, or diuretics. RESULTS There was no difference between the two groups and subgroups with respect to clinical, demographic, ABPM, ventricular volumes, ejection fraction, and tissue Doppler imaging (TDI) parameters. For patients and controls, respectively, global longitudinal strain was - 18.70 ± 3.41 versus - 21.01 ± 3.82 (P < 0.001), and global radial strain was 40.6 ± 9.8 versus 54.8 ± 12.8 (P = 0.004). Peak LV twist and peak LV torsion were not significantly different. The patient subgroup analyses with each other revealed no difference in systolic and diastolic myocardial deformation properties. CONCLUSIONS Strain parameters were reduced in all treated hypertensive children compared to normotensive children, and the various cardiac mechanic parameters were similarly abnormal no matter what type of antihypertensive agent was used.

Abstract
PURPOSE OF REVIEW To update the definition and clinical practice of stage 2 hypertension (HTN) in pediatrics. RECENT FINDINGS The 2017 American Academy of Pediatrics Clinical Practice Guideline (AAP CPG) for Screening and Management of High Blood Pressure in Children and Adolescent includes new normative blood pressure tables for children and adolescents ages 1 to 17 years and new definitions for stage 2 HTN. This review will highlight these aspects as well as new recommendations in the guideline specific to stage 2 HTN. It will outline how the new guideline differs from the previous 2004 guideline, the implications of these differences, and suggested changes in evaluation and management of stage 2 HTN. Lastly, the review will address topics relevant to daily clinical practice including competitive athletic participation, investigation for secondary HTN and HTN comorbidities, and blood pressure-lowering therapy. With the publication of the new AAP CPG introducing revised normative tables, the prevalence of stage 2 HTN in pediatrics is expected to rise. Based on the new guidelines, there is less emphasis on investigation for secondary HTN and more attention to lifestyle modifications for primary HTN. Future research should address whether there is BP level within the stage 2 HTN range above which the approach to evaluation and management should be altered in this heterogeneous patient population.

Abstract
Primary hypertension is not just an adult disorder. Current US population data on children and adolescents demonstrate a prevalence of elevated blood pressure (BP) and hypertension combined of over 10%. Recent reports from prospective cohort studies describe an association of high BP in childhood with hypertension in young adulthood. Excess adiposity is strongly associated with higher BP in childhood and increases risk for hypertension in adulthood. In addition to overweight/obesity, other exposures that raise the risk for high BP include low birthweight, dietary sodium, and stress. Using intermediate markers of cardiovascular injury, studies on hypertensive children report findings of cardiac hypertrophy, vascular stiffness, and early atherosclerotic changes. Impaired cognitive function has also been demonstrated in hypertensive children. Recent advances in clinical and translational research support the concept that the evolution of primary hypertension begins in childhood.

Abstract
Pediatric hypertension guidelines recommend Doppler renal ultrasonography as a screening study for the evaluation of possible renal artery stenosis (RAS) in normal-weight children ≥ 8 years of age who are suspected of having RAS and who will cooperate with the procedure. Obese children are excluded because of technical and vascular concerns. There are no data on RI in obese children. This is a retrospective review of children aged 1.5-18 who received Doppler imaging studies over a 10-year period. A total of 174 patients were studied. There was no significant difference between the RI values based on BMI. Of the 174 individuals in the study 22 obtained follow-up CT/MRA after abnormal Doppler ultrasounds. On advanced imaging 3 were confirmed to have RAS. Obesity does not seem to influence RI.RI alone should not be used as a screening tool for RAS. An approach toward diagnosis is suggested based on BMI, renin levels, and ultrasound.

Abstract
Background The diagnosis of hypertension in children is complex because based on normative values by sex, age and height, and these values vary depending on the environment. Available BP references used, because of the absence of local data, do not correspond to our pediatric population. Accordingly, our study aimed to provide the BP threshold for children and adolescents in Lubumbashi (DRC) and to compare them with German (KIGGS study), Polish (OLAF study) and Chinese (CHNS study) references. Methods We conducted a cross-sectional study among 7523 school-children aged 3 to 17 years. The standardized BP measurements were obtained using a validated oscillometric device (Datascope Accutor Plus). After excluding overweight and obese subjects according to the IOTF definition (n = 640), gender-specific SBP and DBP percentiles, which simultaneously accounted for age and height by using an extension of the LMS method, namely GAMLSS, were tabulated. Results The 50th, 90th and 95th percentiles of SBP and DBP for 3373 boys and 3510 girls were tabulated simultaneously by age and height (5th, 25th, 50th, 75th and 95th height percentile). Before 13 years the 50th and 90th percentiles of SBP for boys were higher compared with those of KIGGS and OLAF, and after they became lower: the difference for adolescents aged 17 years was respectively 8 mmHg (KIGGS) and 4 mmHg (OLAF). Concerning girls, the SBP 50th percentile was close to that of OLAF and KIGGS studies with differences that did not exceed 3 mmHg; whereas the 90th percentile of girls at different ages was high. Our oscillometric 50th and 90th percentiles of SBP and DBP were very high compared to referential ausculatory percentiles of the CHNS study respectively for boys from 8 to 14 mmHg and 7 to 13 mmHg; and for girls from 10 to 16 mmHg and 11 to 16 mmHg. Conclusions The proposed BP thresholds percentiles enable early detection and treatment of children and adolescents with high BP and develop a local program of health promotion in schools and family.

Abstract
While primary hypertension (HTN) clearly occurs in children and adolescents, the approach of many providers to such patients can best be described as ambivalent: the condition may be recognised, but is not acted upon. Such ambivalence may stem from incomplete understanding of the effects of high blood pressure in the young, which in turn is related to the shortage of information on long-term outcomes of primary childhood HTN. However, other evidence on the short- and long-term effects of blood pressure elevation in childhood clearly shows that it is not a benign condition at all. CONCLUSION Childhood HTN warrants action to prevent adult cardiovascular disease.

Abstract
OBJECTIVE Persistent hypertension in adulthood is a leading cause of end-stage renal disease (ESRD). Whether lower blood pressure (BP) values, in the range of prehypertension, are also associated with future occurrence of ESRD is unclear. Even less clear is the potential risk of early prehypertension appearing in adolescence. To address this question, we examined whether BP measurements in the prehypertensive range at age 16-19 years predict adult ESRD. METHODS Medical data on 2194 635 16-19-year-old adolescents examined for medical fitness prior to military service from 1977 to 2013 were linked to the Israeli ESRD registry in this nationwide population-based cohort study. Incident cases of ESRD were recorded. Survival models were applied. RESULTS During 35 007 506 person-years of follow-up (median follow-up 16.8 years), there were 690 ESRD cases, with an overall incidence rate of 1.97 cases per 100 000 person-years. Examinees with elevated BP readings in the prehypertensive range (BP between the 90th and 95th percentiles or between 120 and 139/80-89 mmHg) had increased incidence of ESRD with a hazard ratio of 1.32 (95% confidence interval, 1.11-1.58) adjusted for year of birth, age at examination, sex, BMI, education, socioeconomic status, and country of origin. Hypertension (BP above the 95th percentile or above 140/90 mmHg) was associated with a hazard ratio of 1.44 (95% confidence interval, 1.17-1.79). A spline model demonstrated a nadir of risk at SBP values as low as 94 mmHg. CONCLUSION Asymptomatic, healthy adolescents with prehypertension have a 32% increased risk for subsequent ESRD, compared with adolescents with optimal BP.

Abstract
CONTEXT The relative importance of fitness and fatness with cardiometabolic risk factors is uncertain during the crucial developmental stage of late adolescence. OBJECTIVE We aimed to compare the concurrent influences of cardiorespiratory fitness and fatness in relationship to cardiometabolic risk factors in adolescents from the Western Australian Pregnancy Cohort Study. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional analysis was performed on 1128 participants with complete blood pressure (BP) data and 963 participants with complete blood biochemistry at 17 years of age. Fatness (waist circumference) and cardiorespiratory fitness (physical work capacity 170) were assessed as continuous measures to avoid the use of arbitrary cut points. Analyses used linear regression models adjusted for sex and potential lifestyle confounders. MAIN OUTCOME MEASURE Cardiometabolic risk factors. RESULTS Fatness was positively associated with systolic BP (coefficient, 0.19; P < 0.001; β coefficient, 0.20), triglycerides (log coefficient, 0.009; P < 0.001; β coefficient, 0.24), low-density lipoprotein cholesterol (coefficient, 0.005; P = 0.007; β coefficient, 0.10), and high-sensitivity C-reactive protein (log coefficient, 0.05; P < 0.001; β coefficient, 0.35). There were no significant effects of fitness on any of these measures. A positive association between homeostasis model of assessment for insulin resistance and fatness (log coefficient, 0.02; P < 0.001; β coefficient, 0.33) was attenuated by fitness (log coefficient, -0.0.18; P < 0.001; β coefficient, -0.18). Fatness was inversely associated with high-density lipoprotein cholesterol (HDL-C) in both sexes (coefficient, -0.006; P < 0.001; β coefficient, -0.23), whereas fitness was positively associated with HDL-C only in females (coefficient, 0.08; P = 0.03; β coefficient, 0.15). CONCLUSIONS The adverse effects of central adiposity seen across a broad range of cardiometabolic risk factors were only partially ameliorated by fitness in this adolescent population.

Abstract
BACKGROUND High blood pressure is a risk factor for some disease like stroke, coronary heart disease, and renal failure. High blood pressure in children is an increasing health problem. OBJECTIVES The aim of this study was to determine prevalence of hypertension and pre-hypertension age between 10 to 17 years old. PATIENTS AND METHODS This descriptive analytic study was conducted using multiphase sampling method in Ahvaz (Southwest of Iran). A questionnaire include: height, weight, and body mass index, systolic and diastolic blood pressures filled for each participant. Blood pressure was measured twice for each person. For the diagnosis of hypertension, the fourth report of the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents of the National Health Institute of United States was used. RESULTS Total participants of the study were 1707children and adolescents including 922 boys (54%) and 785 girls (46%). The prevalence of high blood pressure was 1.7% (2.5% in boys and 0.8%). The prevalence of pre-hypertension was 9%(7.6% in boys, 10.6% in girls). The mean systolic and diastolic blood pressures increased with increasing body mass index. CONCLUSIONS The prevalence of high blood pressure was found to be lower than other studies in our country. The prevalence of the high blood pressure in boys was significantly higher than girls. This study, like other studies showed high correlation between being overweight and an increase in systolic and diastolic blood pressure.

Abstract
The purpose of this study is to track the trends of low visual acuity (VA) from 2005 to 2014, and to investigate its associations with systemic blood pressure (BP) components among adolescents in Northeast China. A total of 55320 students of Han nationality aged 13 to 18 years were included. There has been a significant increase in the prevalence of low VA, with 31.3% in 2005, 40.2% in 2010 and 43.4% in 2014. In multivariable-adjusted logistic regression models, each 1-mm Hg increment in systolic BP (SBP) was associated with 0.8% (95% confidence interval [CI]: 0.1–1.6%), 0.5% (95% CI: 0.1–0.9%) and 1.1% (95% CI: 0.6–1.6%) increased odds of low VA for males in 2005, 2010 and 2014; each 1-mm Hg increment in pulse pressure (PP) was associated with 1.6% (95% CI: 0.7–2.5%), 0.8% (95% CI: 0.4–1.2%) and 1.2% (95% CI: 0.7–1.7%) increased odds of low VA. Higher PP categories had greater odds for low VA compared with the reference group. Similar associations were not observed for females. We conclude that higher prevalence of low VA was significantly associated with higher SBP and PP in males. Furthermore, there was a dose-dependent association between the prevalence of low VA and the levels of PP.

Abstract
Background Epidemiological studies have demonstrated the influence of environmental factors on HBP in the population of Lithuanian children, although the role of genetic factors in hypertension has not yet been studied. The aim of this study was to assess the distribution of AGTR1, AGT, and ACE genotypes in the Lithuanian child population and to determine whether these genotypes have an impact on HBP in childhood. Methods This cross-sectional study enrolled 709 participants aged 12–15 years. The subjects were genotyped for AGT (M235 T, rs699), AGTR1 (A1166C, rs5186), and ACE (rs4340) gene polymorphisms using real-time and conventional polymerase chain reactions. Blood pressure and anthropometric parameters were measured. Results The prevalence of HBP was 38.6% and was more frequently detected in boys than in girls (47.9% vs. 29.5%; p < 0.001). No significant differences in the frequencies of the AGT or AGTR1 genotypes or alleles between boys and girls were observed, except for ACE genotypes. The mean SBP value was higher in HBP subjects with ACE ID genotype compared to those with ACE II homozygotes (p = 0.04). No significant differences in BP between different AGT and AGTR1 genotype groups were found. Boys who carried the ACE ID + DD genotypes had higher odds of having HBP than carriers of the ACE II genotype did (controlling for the body mass index (BMI): ORMH = 1.83; 95% CI, 1.11–3.02, p = 0.024; and controlling for waist circumference (WC): ORMH = 1.76; 95% CI, 1.07–2.92, p = 0.035). These associations were not significant among girls. The same trend was observed in the multivariate analysis – after adjustment for BMI and WC, only boys with ACE ID genotype and ACE ID + DD genotypes had statistically significantly increased odds of HBP (aOR = 2.05; 95% CI, 1.19–3.53 (p = 0.01) and aOR = 1.82; 95% CI, 1.09–3.04 (p = 0.022), respectively). Conclusions The evaluated polymorphisms of the AGT and AGTR1 genes did not contribute to the presence of HBP in the present study and may be seen as predisposing factors, while ACE ID genotypes were associated with significantly increased odds for the development of HBP in the Lithuanian child and adolescent population - especially in boys.

Abstract
These pediatric hypertension guidelines are an update to the 2004 "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents." Significant changes in these guidelines include (1) the replacement of the term "prehypertension" with the term "elevated blood pressure," (2) new normative pediatric blood pressure (BP) tables based on normal-weight children, (3) a simplified screening table for identifying BPs needing further evaluation, (4) a simplified BP classification in adolescents ≥13 years of age that aligns with the forthcoming American Heart Association and American College of Cardiology adult BP guidelines, (5) a more limited recommendation to perform screening BP measurements only at preventive care visits, (6) streamlined recommendations on the initial evaluation and management of abnormal BPs, (7) an expanded role for ambulatory BP monitoring in the diagnosis and management of pediatric hypertension, and (8) revised recommendations on when to perform echocardiography in the evaluation of newly diagnosed hypertensive pediatric patients (generally only before medication initiation), along with a revised definition of left ventricular hypertrophy. These guidelines include 30 Key Action Statements and 27 additional recommendations derived from a comprehensive review of almost 15 000 published articles between January 2004 and July 2016. Each Key Action Statement includes level of evidence, benefit-harm relationship, and strength of recommendation. This clinical practice guideline, endorsed by the American Heart Association, is intended to foster a patient- and family-centered approach to care, reduce unnecessary and costly medical interventions, improve patient diagnoses and outcomes, support implementation, and provide direction for future research.

Abstract
BACKGROUND This study examined the degree to which sex, weight status, and the presence of hypertension and obesity in parents/grandparents were associated with systolic (SBP) and diastolic (DBP) blood pressure (BP) among African American youth in a pilot offspring study examining obesity-related cardiovascular disease (CVD) risks among adolescents. RESULTS Fully adjusted linear regression models of the total sample produced results indicating that obesity was associated with BP (SBP: β = 7.08, P < 0.01; DBP: β = 8.14, P < 0.001). Sex-stratified analyses indicated that overweight and obesity were associated with SBP (overweight: β = 6.77, P < 0.01; obese: β = 11.65, P < 0.001) and obesity was correlated with DBP (β = 9.86, P < 0.001) among males. For females, overweight was correlated with SBP (β = 4.11, P < 0.05) while obesity was associated with DBP (β = 6.98, P < 0.01). Attempting to lose weight was inversely related to SBP (β = -4.01, P < 0.05) in the full sample and among males (β = -11.94, P < 0.001). Familial presence of hypertension and/or obesity was significantly associated with SBP among adolescent females but not males. CONCLUSIONS The relationship between weight status, familial hypertension and obesity status, and BP among adolescents vary by sex. This study underscores the need for additional research investigating the relationship between individual sex, weight status, BP and familial BP, and obesity status on risk among African American adolescents.
