Early Onset Hypertension Is Associated With Hypertensive End-Organ Damage Already by MidLife

Multiethnic norms for blood pressure response to submaximal exercise testing in young-to-middle adulthood and associations with hypertension: The NHANES dataset

The blood pressure (BP) response during exercise testing is a robust correlate of hypertension in middle-to-older White people, but whether this extends to a healthy, young-to-middle-aged multiethnic population is unknown. Moreover, it is unclear what constitutes an exaggerated BP to submaximal exercise, which is a more reliable and stronger correlate of hypertension than maximal testing. The NHANES dataset was used to interrogate the association of submaximal exercise BP with current hypertension and to provide multiethnic norms for BP responses in young-to-middle-aged adults. The analyses combined NHANES cycles wherein treadmill exercise testing was conducted with an analytic sample of 2544 participants aged 12-49 years (Female: White = 467; Black = 324; Hispanic = 439; Male: White = 493, Black = 351; Hispanic = 470). Weighted logistic models were fitted to test associations between exercise BP and hypertension. Age, sex, and race-specific percentiles were estimated. Exaggerated systolic BP (SBP) responses to exercise testing were defined as readings ≥90th percentile, and ≥ROC-derived cutoff. Regardless of race, sex, exercise workload, clinical and socioeconomic characteristics, a 5-mmHg increase in SBP and diastolic BP during stage 1 of exercise testing was associated with a 15% (aOR: 1.15, 95% CI: 1.08-1.21), and 31% (aOR: 1.31, 95% CI: 1.22-1.40) higher odds for hypertension, respectively. Black males had the highest proportion of exaggerated SBP responses (44%, 95% CI: 36-53%) when defined only via ROC-derived cutoffs. BP responses during submaximal exercise were associated with hypertension, irrespective of race in young-to-middle adulthood. Still, the exaggerated SBP response to exercise of Black males suggests uncontrolled high BP not detected at rest.

Early onset of hypertension and increased relative risks of chronic kidney disease and mortality: two population-based cohort studies in United Kingdom and Hong Kong

This study aimed to evaluate the association between hypertension (HT) onset age and later risks of chronic kidney diseases (CKD) and mortality. Adult patients without CKD from 2008 to 2013 were identified using electronic medical records from United Kingdom (UK) and Hong Kong (HK). Patients newly diagnosed with HT and those without were included in the HT and control groups, respectively. All subjects were stratified into six age groups (18-39, 40-49, 50-59, 60-69, 70-79, ≥80). Multivariable Cox proportional hazard regression, adjusted with baseline characteristics and fine stratification weights, was conducted to investigate the association between HT onset and risks of CKD, renal decline, end-stage renal disease (ESRD), and all-cause mortality. Subjects were followed up from baseline until an outcome event, death, or administrative end of the cohort, whichever occurred first. A total of 4,413,551 and 3,132,951 subjects were included in the UK and HK cohorts, respectively. HT was significantly associated with increased risks of outcome, but the hazard ratios (HRs) decreased with increasing onset age. In the UK cohort, the HRs (95% confidence intervals) for subjects aged 18-39 and ≥80 were 3.69 (3.53, 3.86) and 2.01 (1.96, 2.06) for CKD, 3.83 (3.60, 4.07) and 3.17 (2.97, 3.38) for renal decline, 17.26 (14.34, 20.77) and 2.55 (2.12, 3.07) for ESRD, 2.88 (2.66, 3.11) and 1.09 (1.07, 1.12) for mortality. The HK cohort exhibited a similar pattern. Our study concluded that early onset of HT significantly affects renal health later in life, while the contribution decreases with the onset age of HT.

Association between TyG-BMI and early-onset hypertension: evidence from NHANES

Early-onset hypertension (EHT) is a growing concern due to its long-term cardiovascular risks. This study investigated the association between the triglyceride glucose-body mass index (TyG-BMI) and EHT in a nationally representative US sample. EHT was defined as physician-reported hypertension diagnosed before age 40. We used weighted logistic regression models to assess the association between TyG-BMI and EHT, adjusting for potential confounders. Mediation analysis was conducted to examine the role of oxidative stress and inflammation markers in this association. We analyzed data from 5193 adults with age under 40 years from the National Health and Nutrition Examination Survey (NHANES) 2009-2018.Participants with EHT had significantly higher TyG-BMI compared to those without EHT (P < 0.001). In multivariable analysis, the highest quartile of Ty-BMI was independently associated with 6.47-fold increased odds of EHT (OR: 6.47, 95% CI: 4.35-9.61) compared to the lowest quartile. This association remained significant across subgroups stratified by gender, race, and smoking status. Gamma-glutamyl transferase (GGT) and uric acid were identified as potential mediators. Higher TyG-BMI is significantly associated with EHT. TyG-BMI may serve as a readily available clinical tool for early identification and management of individuals at increased risk for EHT, facilitating timely interventions to mitigate long-term cardiovascular risks.

Association of Duration of Recognized Hypertension and Stroke Risk: The REGARDS Study

BACKGROUND

The focus for reducing hypertension-related cardiovascular disease is the management of blood pressure. Limited data are available on the potential benefit of delaying the onset of hypertension.

METHODS

Stroke-free Black and White participants from the REGARDS cohort study (Reasons for Geographic and Racial Differences in Stroke; recruited 2003-2007) were followed through 2022 for incident stroke events. Participants were stratified by duration of recognized hypertension: normotensive (0 years), ≤5 years, 6 to 20 years, or 21+ years. The baseline systolic blood pressure (SBP), the number of classes of antihypertensive medications, and the risk of incident stroke were assessed by duration strata adjusting for demographics, cerebrovascular risk factors, SBP, and use of antihypertensive medications (where appropriate).

RESULTS

Of 30 239 study participants, we included 27 310 participants (mean age, 65 years; 45% male), followed a median of 12.4 years, during which 1763 incident stroke events occurred. On average, participants with hypertension duration ≤5 years, 6 to 20 years, and 21+ years were taking 1.68 (95% CI, 1.65-1.71), 2.04 (95% CI, 2.01-2.07), and 2.28 (95% CI, 2.25-2.31) classes of antihypertensive medications, respectively. The adjusted mean SBP level was higher with each increasing duration of recognized hypertension (0, ≤5, 6-20, and 21+ years): 123.9 mm Hg (95% CI, 123.3-124.6), 129.7 mm Hg (95% CI, 129.1-130.2), 131.7 mm Hg (95% CI, 130.6-131.5), and 132.6 mm Hg (95% CI, 132.0-133.1). Compared with normotensive individuals, the hazard for incident stroke increased from 1.31 (95% CI, 1.05-1.63) for ≤5 years duration, 1.50 (95% CI, 1.21-1.87) for 6 to 20 years duration, and 1.67 (95% CI, 1.32-2.10) for 21+ years duration.

CONCLUSIONS

Longer duration of recognized hypertension was associated with more classes of antihypertensive medications, higher mean SBP, and higher stroke risk even after adjustment for age and SBP. Collectively, this suggests that delaying the onset of hypertension could reduce the burden of stroke.

The relationship between the age of onset of hypertension and chronic kidney disease: a cross-sectional study of the American population

Background

Hypertension can damage multiple target organs. The younger the age of onset of hypertension is, the greater the risk of cardiovascular disease (CVD) and cardiovascular death. Chronic kidney disease (CKD) is a complication of hypertension, but few studies have investigated the relationship between the age of onset of hypertension and CKD.

Objective

We investigated the relationship between the age of onset of hypertension and CKD.

Method

We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2007-2018. A total of 30,613 participants were assigned to one of four groups. Group 1, no hypertension (n = 19,516); Group 2, age of onset <35 years (n = 2,180); Group 3, 35≤ age of onset <45 years (n = 2,128); and Group 4, age of onset ≥45 years (n = 6,789). Logistic regression analysis was used to evaluate the relationship between the age of onset of hypertension and CKD.

Results

After adjusting for potential confounders, a younger age at onset of hypertension was associated with a greater risk of developing CKD compared with the absence of hypertension (Group 2 OR: 2.52, 95% CI: 1.53-4.14, P < 0.001; Group 3 OR: 1.59, 95% CI: 1.01-2.51, P = 0.048; Group 4 OR: 1.54, 95% CI: 1.00-2.38, P = 0.050).

Conclusions

There was a strong association between the age of onset of hypertension and CKD. The younger the age of onset of hypertension is, the greater the risk of CKD.

Global burden of disease attributable to metabolic risk factors in adolescents and young adults aged 15-39, 1990-2021

BACKGROUND

Metabolic risk factors are a significant cause of global burden among adolescents and young adults, but there is a lack of attention to the burden attributable to these metabolic risk factors globally.

AIMS

This study aims to provide comprehensive estimates of five important metabolic risk factors and the attributable disease burden in people aged 15-39 years from 1990 to 2021, based on the Global Burden of Disease Study (GBD) database.

METHODS

Global total deaths and disability-adjusted life years (DALYs) were used to describe the burden attributable to five common metabolic risk factors, including high fasting plasma glucose (FPG), high low-density lipoprotein cholesterol (LDL-C), high systolic blood pressure (SBP), high body mass index (BMI), and kidney dysfunction, in adolescents and young adults. The estimated annual percentage changes (EAPC) of DALYs were utilized to depict the trends from 1990 to 2021.

RESULTS

From 1990 to 2021, the DALY rates attributable to all metabolic risk factors showed a globally significant upward trend, with EAPC reaching 33.0 % (27.4-38.7). Compared to females, males had a heavier burden and a more significant increase in deaths and DALYs attributable to metabolic risk factors. High BMI and high FPG have become the top two metabolic risk factors in 2021, with summary exposure variables (SEV) rising by 84.2 % and 53.6 %, respectively. Low-middle socio-demographic index (SDI), middle SDI, and high SDI regions experienced upward regional trends in DALY rates, while low SDI regions remained stable. Among 204 countries and territories, 101 (49.5 %) showed a significant increase in DALY rates, as indicated by the EAPC.

CONCLUSIONS

There is a substantial global burden attributable to metabolic risk factors in adolescents and young adults in 2021, especially high BMI and high FPG. This calls for further investigation and intervention to address this emerging trend.

Association of alcohol consumption with hypertension or prehypertension in Chinese adolescent: A cohort study of the China Health and Nutrition Survey

This study was conducted to investigate the association between alcohol consumption in adolescence and the risk of hypertension or prehypertension development in early adulthood. This cohort study included adolescent participants aged 12-18 years from the 2000-2011 China Health and Nutrition Survey. Cox proportional risk regression models were used to analyze the associations of the frequency of alcohol consumption, alcohol intake, and type of alcohol with the risk of developing hypertension or prehypertension. Restricted cubic spline analysis was used to assess the dose-response relationships for alcohol intake and their hazard ratios (HRs). A total of 1556 participants were included in the final analysis. Among the overall population, 448 (30.81%) and 35 (34.31%) participants developed hypertension or prehypertension, respectively. Compared with no alcohol consumption, alcohol consumption ≥ 2 times/week and consumption of ≥2 types of alcohol were associated with an increased risk of hypertension and prehypertension, with HRs of 1.97 (95% confidence interval [CI] 1.17-3.34; p = 0.011) and 1.77 (95% CI 1.01-3.09; p = 0.046), respectively. Alcohol intake of > 96 mL/week was associated with an increased risk of hypertension and prehypertension, with HRs of 2.09 (95% CI 1.12-3.90; p = 0.020) and 2.07 (95% CI 1.11-3.84; p = 0.021), respectively. The restricted cubic spline analysis showed that the risk of developing high blood pressure or prehypertension tends to increase with increasing alcohol consumption. Heavy alcohol consumption in adolescence increased the risk of developing hypertension and prehypertension in early adulthood.

Pediatric Blood Pressure and Cardiovascular Health in Adulthood

PURPOSE OF REVIEW

This review summarizes current knowledge on blood pressure in children and adolescents (youth), with a focus on primary hypertension-the most common form of elevated blood pressure in this demographic. We examine its etiology, progression, and long-term cardiovascular implications. The review covers definitions and recommendations of blood pressure classifications, recent developments in measurement, epidemiological trends, findings from observational and clinical studies, and prevention and treatment, while identifying gaps in understanding and suggesting future research directions.

RECENT FINDINGS

Youth hypertension is an escalating global issue, with regional and national variations in prevalence. While the principles of blood pressure measurement have remained largely consistent, challenges in this age group include a scarcity of automated devices that have passed independent validation for accuracy and a generally limited tolerance for ambulatory blood pressure monitoring. A multifaceted interplay of factors contributes to youth hypertension, impacting long-term cardiovascular health. Recent studies, including meta-analysis and sophisticated life-course modelling, reveal an adverse link between youth and life-course blood pressure and subclinical cardiovascular outcomes later in life. New evidence now provides the strongest evidence yet linking youth blood pressure with clinical cardiovascular events in adulthood. Some clinical trials have expanded our understanding of the safety and efficacy of antihypertensive medications in youth, but this remains an area that requires additional attention, particularly regarding varied screening approaches. This review outlines the potential role of preventing and managing blood pressure in youth to reduce future cardiovascular risk. A global perspective is necessary in formulating blood pressure definitions and strategies, considering the specific needs and circumstances in low- and middle-income countries compared to high-income countries.

Prognostic value of the triglyceride-glucose index for adverse cardiovascular outcomes in young adult hypertension

BACKGROUND

The triglyceride-glucose (TyG) index is a reliable marker of insulin resistance that is involved in the progression of hypertension. This study aimed to evaluate the association of the TyG index with the risk for major cardiovascular events (MACE) in young adult hypertension.

METHODS

A total of 2,651 hypertensive patients aged 18-40 years were consecutively enrolled in this study. The TyG index was calculated as Ln [triglycerides × fasting plasma glucose/2]. The cutoff value for an elevated TyG index was determined to be 8.43 by receiver-operating characteristic curve analysis. The primary endpoint was MACE, which was a composite of all-cause death, non-fatal myocardial infarction, coronary revascularization, non-fatal stroke, and end-stage renal dysfunction. The secondary endpoints were individual MACE components.

RESULTS

During the median follow-up time of 2.6 years, an elevated TyG index was associated with markedly increased risk of MACE (adjusted hazard ratio [HR] 3.440, P < 0.001) in young hypertensive adults. In subgroup analysis, the elevated TyG index predicted an even higher risk of MACE in women than men (adjusted HR 6.329 in women vs. adjusted HR 2.762 in men, P for interaction, 0.001); and in patients with grade 2 (adjusted HR 3.385) or grade 3 (adjusted HR 4.168) of hypertension than those with grade 1 (P for interaction, 0.024). Moreover, adding the elevated TyG index into a recalibrated Systematic COronary Risk Evaluation 2 model improved its ability to predict MACE.

CONCLUSIONS

An elevated TyG index is associated with a higher risk of MACE in young adult hypertension, particularly in women and those with advanced hypertension. Regular evaluation of the TyG index facilitates the identification of high-risk patients.

Early-onset alcohol, tobacco, and illicit drug use with age at onset of hypertension: a survival analysis

PURPOSE

To examine the associations of age when first substance use and early-onset substance use before age 18 with age at onset (AAO) of hypertension.

METHODS

This study included 19,270 individuals with AAO of hypertension from the 2015-2019 National Survey on Drug Use and Health. Age when first use of 10 substance use variables included alcohol, daily cigarettes, cigars, smokeless tobacco, marijuana, cocaine, hallucinogens, lysergic acid diethylamide (LSD), inhalants, and methamphetamine use. The outcome was AAO of hypertension and variable cluster analysis was used to classify the exposures and outcome. Substance use status was classified into three categories: early-onset substance use (first used substance before age 18), late-onset substance use (first used substance after age 18), and never used.

RESULTS

The mean AAO of hypertension was 42.7 years. Age when first use of 10 substance use variables had significant correlations with AAO of hypertension (all p values < 0.001). Individuals with early-onset alcohol, cigars, smokeless tobacco, marijuana, hallucinogens, inhalants, cocaine, LSD, and methamphetamine use revealed significantly earlier onset of hypertension than those never used. Compared with never used substances, the Cox regression model showed that early-onset alcohol, smokeless tobacco, marijuana, inhalants, and methamphetamine use had an increased risk of AAO of hypertension [hazard ratio (HR) (95%CI) = 1.22 (1.13, 1.31), 1.36 (1.24, 1.49), 1.85 (1.75, 1.95), 1.41 (1.30, 1.52), and 1.27 (1.07,1.50), respectively].

CONCLUSION

These findings suggest that intervention strategies or programs focusing on preventing early-onset substance use before age 18 may delay the onset of adult hypertension.

New-onset hypertension as a contributing factor to the incidence of atrial fibrillation in the elderly

Hypertension and atrial fibrillation are closely related. However, hypertension is already prevalent in young adults, but atrial fibrillation usually occurs in the elderly. In the present analysis, we investigated incident atrial fibrillation in relation to new-onset hypertension in an elderly Chinese population. Our study participants were elderly (≥65 years) hypertensive residents, recruited from community health centers in the urban Shanghai (n = 4161). Previous and new-onset hypertension were defined as the use of antihypertensive medication or elevated systolic/diastolic blood pressure (≥140/90 mmHg), respectively, at entry and during follow-up on ≥ 2 consecutive clinic visits. Atrial fibrillation was detected by a 30-s single-lead electrocardiography (ECG, AliveCor® Heart Monitor) and further evaluated with a regular 12-lead ECG. During a median of 2.1 years follow-up, the incidence rate of atrial fibrillation was 7.60 per 1000 person-years in all study participants; it was significantly higher in patients with new-onset hypertension (n = 368) than those with previous hypertension (n = 3793, 15.76 vs. 6.77 per 1000 person-years, P = 0.02). After adjustment for confounding factors, the hazard ratio for the incidence of atrial fibrillation was 2.21 (95% confidence interval 1.15-4.23, P = 0.02) in patients with new-onset hypertension versus those with previous hypertension. The association was even stronger in those aged ≥ 75 years (hazard ratio 2.70, 95% confidence interval 1.11-6.56, P = 0.03). In patients with previous hypertension, curvilinear association (P for non-linear trend = 0.04) was observed between duration of hypertension and the risk of incident atrial fibrillation, with a higher risk in short- and long-term than mid-term duration of hypertension. Our study showed a significant association between new-onset hypertension and the incidence of atrial fibrillation in elderly Chinese. In an elderly Chinese population with previous and new-onset hypertension, we found that the new-onset hypertension during follow-up, compared with previous hypertension, was associated with a significantly higher risk of incident atrial fibrillation. In patients with previous hypertension, curvilinear association was observed between duration of hypertension and the risk of incident atrial fibrillation, with a higher risk in short- and long-term than mid-term duration of hypertension.

Primary Arterial Hypertension Associated with Cognitive Dysfunction in Young Adults: Results from a Cross-Sectional Controlled Study

Despite evidence of primary hypertension (PH)-associated cognitive dysfunction in pediatric, middle-aged, and older adult populations, respective data in young adults remains scarce. We aimed to define differences in cognitive performance between individuals with PH and healthy controls in early adulthood. A convenience sample of young adults (age 18-45 years) with PH and their healthy sex, age, education, and household income matched counterparts were cross-sectionally tested for verbal fluency, verbal memory, general intelligence, reaction speed, attention, visual memory, and executive functioning. Between-group differences were determined using Student's t and Mann-Whitney U tests. Sensitivity analysis was performed by adjusting for body mass index (BMI) in analysis of covariance (ANCOVA) and regression models. Thirty-three adults with PH (22, 66.7% male, median age 38.8, interquartile range (IQR) = 33.2-41.6 years) and twenty-two healthy controls (9, 40.9% male, median age 36.1, IQR = 27.5-39.8 years) completed the neuropsychological assessment. Participants with PH performed worse on computerized tasks of reaction time (median response time (Z = -2.019, p = 0.044), median time for release of response button (Z = -2.509, p = 0.012)) and sustained attention (signal detection measure, RVPA (t = 2.373, p = 0.021), false alarms ÷ (false alarms + correct rejections), RVPPFA (Z = -2.052, p = 0.040)). The group variable was not a statistically significant predictor of performance in these domains after adjustment for BMI (p > 0.05). In regression analyses, high office systolic blood pressure (oSBP) was independently associated with poor sustained attention (βSBP(st.) = -0.283, multiple R2 = 0.252 (RVPA), βSBP(st.) = 0.551, multiple R2 = 0.386 (RVPPFA)). Young adults with PH were found to perform worse in tasks of response speed and sustained attention. While the difference between neuropsychological evaluation results in PH and control groups was confounded by BMI, oSBP measures were independently related to sustained attention. The selectivity of PH-associated cognitive profile in young adults has to be confirmed in larger trials.

Effect of Meditation, Mindfulness-Based Stress Reduction, and Relaxation Techniques as Mind-Body Medicine Practices to Reduce Blood Pressure in Cardiac Patients: A Systematic Review and Meta-Analysis

Elevated blood pressure is one of the major risk factors for cardiovascular diseases. Available evidence on mind-body medicine (MBM) techniques on blood pressure is inconclusive and provides conflicting results. The objective of the current systematic review and meta-analysis is to evaluate the effect of MBM techniques on blood pressure in patients with cardiovascular disease. Randomized control trials (RCTs) done between the years 2000 and 2020 on cardiovascular disease, using MBM techniques such as meditation, mindfulness-based stress reduction and relaxation techniques were searched through electronic databases such as PubMed, Cumulative Index to Nursing & Allied Health (CINAHL), EMBASE and Cochrane Library. Three authors independently performed article selection, data extraction and validation. Meta-analysis was performed using a random effect model and standardized mean difference (SMD) with 95% confidence interval (CI) estimated for the effect size. Fifteen RCTs with 927 patients were included in the meta-analysis. Heterogeneity among the studies was very high for all analyses (I2>94%). For studies comparing systolic blood pressure, MBM interventions show a significant (p=0.01) effect when compared to conventional treatment, an overall estimated effect size of SMD - 0.78 (95% CI: -1.36, -0.20). For studies comparing the diastolic blood pressure, MBM intervention did not show any significant effect when compared to the conventional treatment, an overall effect size of SMD -0.26 (95% CI: -0.91, 0.39). The findings of the meta-analysis suggest that MBM interventions may improve systolic blood pressure alone in patients with cardiac diseases. With high heterogeneity and low quality of the included studies, more robust evidence is required before suggesting MBM as an effective treatment modality for reducing blood pressure in cardiovascular diseases.

Dietary Fructose and Sodium Consumed during Early Mid-Life Are Associated with Hypertensive End-Organ Damage by Late Mid-Life in the CARDIA Cohort

We aimed to investigate how dietary fructose and sodium impact blood pressure and risk of hypertensive target organ damage 10 years later. Data from n = 3116 individuals were obtained from the Coronary Artery Risk Development in Young Adults (CARDIA) study. Four groups were identified based on the four possible combinations of the lower and upper 50th percentile for sodium (in mg) and fructose (expressed as percent of total daily calories). Differences among groups were ascertained and logistic regression analyses were used to assess the risk of hypertensive target organ damage (diastolic dysfunction, coronary calcification and albuminuria). Individuals in the low-fructose + low-sodium group were found to have lower SBP compared to those in the low-fructose + high-sodium and high-fructose + high-sodium groups (p < 0.05). The highest risk for hypertensive target organ damage was found for albuminuria only in the high-fructose + high-sodium group (OR = 3.328, p = 0.006) while female sex was protective across all groups against coronary calcification. Our findings highlight that sodium alone may not be the culprit for hypertension and hypertensive target organ damage, but rather when combined with an increased intake of dietary fructose, especially in middle-aged individuals.

Prevalence of hypertension and high-normal blood pressure among young adults in Zimbabwe: findings from a large, cross-sectional population-based survey

BACKGROUND

Hypertension is the greatest driver of cardiovascular mortality and onset might be in youth. We aimed to investigate the prevalence of and risk factors for elevated blood pressure (hypertension ≥140 mm Hg systolic, ≥90 mm Hg diastolic, or both) and high-normal blood pressure (130-139 mm Hg systolic, 85-89 mm Hg diastolic, or both) among youth in Zimbabwe.

METHODS

A population-based, cross-sectional survey of randomly sampled youth aged 18-24 years from 24 urban and peri-urban communities in three provinces (Harare, Bulawayo, and Mashonaland East) in Zimbabwe was conducted between Oct 4, 2021, and June 2, 2022. Standardised questionnaires were used by research assistants to collect sociodemographic, behavioural, and clinical data. Height, bodyweight, and blood pressure were recorded. Three seated blood pressure measurements were taken at standardised timepoints during participant interview using a digital sphygmomanometer and cuffs sized on mid-upper arm circumference. The association of potential risk factors with elevated blood pressure was examined using multivariable logistic regression.

FINDINGS

17 682 (94·4%) of 18 729 eligible participants were recruited, 17 637 (99·7%) of whom had complete data, and 16 883 (95·7%) of whom were included in the final study sample after excluding 754 (4·3%) pregnant women. The median age was 20 years (IQR 19-22), 9973 (59·1%) participants were female, and 6910 (40·9%) were male. The prevalence of hypertension was 7·4% (95% CI 7·0-7·8) and high-normal blood pressure was 12·2% (11·7-12·7). Overall, prevalence of hypertension was higher in men (8·7% [95% CI 8·2-9·6]) than in women (6·6% [6·0-6·9]), but with age increased to similar levels (at age 18 years 7·3% [6·2-8·6] and 4·3% [3·5-5·2]; at age 23-24 years 10·9% [9·3-12·6] and 9·5% [8·4-10·7] in men and women, respectively). After adjusting for factors associated with hypertension in the crude analysis, hypertension was associated with male sex (adjusted odds ratio 1·53 [95% CI 1·36-1·74]), increasing age (age 19-20 years 1·20 [1·00-1·44]; age 21-22 years 1·45 [1·20-1·75]; age 23-24 years 1·90 [1·57-2·30], vs age 18 years), and BMI of 30·0 kg/m2 or more (1·94 [1·53-2·47] vs 18·5-24·9 kg/m2). A BMI of 18·5 kg/m2 or less (0·79 [0·63-0·98] vs 18·5-24·9 kg/m2) and living with HIV (0·71 [0·55-0·92]) were associated with lower odds of hypertension.

INTERPRETATION

Prevalence of elevated blood pressure is high among urban and peri-urban youth in Zimbabwe and increases rapidly with age. Further research is needed to understand drivers of blood pressure elevation and the extent of target organ damage in youth in Zimbabwe and similar sub-Saharan African settings, to guide implementation of prevention and management strategies.

Thymoquinone: A comprehensive review of its potential role as a monotherapy for metabolic syndrome

Metabolic syndrome (MetS) is a widespread global epidemic that affects individuals across all age groups and presents a significant public health challenge. Comprising various cardio-metabolic risk factors, MetS contributes to morbidity and, when inadequately addressed, can lead to mortality. Current therapeutic approaches involve lifestyle changes and the prolonged use of pharmacological agents targeting the individual components of MetS, posing challenges related to cost, compliance with medications, and cumulative side effects. To overcome the challenges associated with these conventional treatments, herbal medicines and phytochemicals have been explored and proven to be holistic complements/alternatives in the management of MetS. Thymoquinone (TQ), a prominent bicyclic aromatic compound derived from Nigella sativa emerges as a promising candidate that has demonstrated beneficial effects in the treatment of the different components of MetS, with a good safety profile. For methodology, literature searches were conducted using PubMed and Google Scholar for relevant studies until December 2023. Using Boolean Operators, TQ and the individual components of MetS were queried against the databases. The retrieved articles were screened for eligibility. As a result, we provide a comprehensive overview of the anti-obesity, anti-dyslipidaemic, anti-hypertensive, and anti-diabetic effects of TQ including some underlying mechanisms of action such as modulating the expression of several metabolic target genes to promote metabolic health. The review advocates for a paradigm shift in MetS management, it contributes valuable insights into the multifaceted aspects of the application of TQ, fostering an understanding of its role in mitigating the global burden of MetS.

Mindsets and self-efficacy beliefs among individuals with type 2 diabetes

Growth mindsets and self-efficacy beliefs have been known to predict and promote resilience, challenge seeking, and improved outcomes in areas such as education and intelligence. However, little is known about the role of these two potentially influential beliefs in the context of type 2 diabetes (T2D), specifically in terms of whether and in which domains (i.e., beliefs toward general life, general health, or condition-specific domains) these beliefs-or lack thereof-is prevalent among individuals with T2D. Given the lifelong challenges that individuals with diabetes often encounter with managing their disease, many may slip into a conceding negative belief that their diabetes is "too difficult to control" or simply "out of their hands," inhibiting proactive self-management efforts. Results from our study (n = 893) revealed that individuals with T2D had a significantly lower growth mindset towards their blood glucose level and lower self-efficacy towards their general health, blood glucose, and cholesterol levels compared to those without T2D. Among participants with T2D, further analyses showed a pattern of higher HbA1c among those with lower growth mindsets and self-efficacy toward their general health or blood glucose level. These findings identify the belief-domains that may pose barriers to necessary self-care behaviors, informing future interventions to promote improved diabetes care and management.

Association of the age of onset of metabolic syndrome with the risk of all cancer types

BACKGROUND

The association between the age at onset of metabolic syndrome and cancer risk remains unknown. This study explored the association between age at metabolic syndrome onset and the risk of overall and site-specific cancer incidence.

METHODS

This study included 31,688 participants with new-onset metabolic syndrome and 31,688 participants matched according to sex, age (±1 y), and examination year among the 179,328 participants who underwent Kailuan health examinations from 2006 to 2017 in Tangshan, China. Weighted Cox regression was used to calculate the hazard ratios and 95% confidence intervals of new-onset metabolic syndrome for overall and site-specific cancer incidence across age groups. Population-attributable risk proportions were used to estimate the number of cases that could be prevented by eliminating the risk factors from the population.

RESULTS

During an average follow-up period of 10.22 y, we identified 2,710 cases of cancer and 4,218 deaths that occurred before the diagnosis of cancer. With an increase in metabolic syndrome onset age, the hazards of overall cancer incidence were gradually attenuated. The average hazard ratios (95% confidence intervals) of overall cancer were 1.94 (1.25-2.99) for metabolic syndrome onset age <45 year old, 1.41 (1.15-1.71) for age 45-54 years old, 1.38 (1.11-1.73) for age 55-64 years old, and 1.07 (0.89-1.28) for age ≥65 years old, respectively (p for interaction = 0.005). Similar results were obtained for colorectal, liver, and breast cancers in the site-specific analysis.

CONCLUSIONS

New-onset metabolic syndrome was associated with a higher risk of overall cancer and incidence of several types of cancer, and the associations were stronger with a younger age of onset.

Age-dependent topic modeling of comorbidities in UK Biobank identifies disease subtypes with differential genetic risk

The analysis of longitudinal data from electronic health records (EHRs) has the potential to improve clinical diagnoses and enable personalized medicine, motivating efforts to identify disease subtypes from patient comorbidity information. Here we introduce an age-dependent topic modeling (ATM) method that provides a low-rank representation of longitudinal records of hundreds of distinct diseases in large EHR datasets. We applied ATM to 282,957 UK Biobank samples, identifying 52 diseases with heterogeneous comorbidity profiles; analyses of 211,908 All of Us samples produced concordant results. We defined subtypes of the 52 heterogeneous diseases based on their comorbidity profiles and compared genetic risk across disease subtypes using polygenic risk scores (PRSs), identifying 18 disease subtypes whose PRS differed significantly from other subtypes of the same disease. We further identified specific genetic variants with subtype-dependent effects on disease risk. In conclusion, ATM identifies disease subtypes with differential genome-wide and locus-specific genetic risk profiles.

Childhood Parental Incarceration and Adult-Onset Hypertension and Cardiovascular Risk

Importance

Parental incarceration is an adverse childhood experience that disproportionately affects racially minoritized individuals and has been associated with long-term health risks. Although cardiovascular disease remains the primary cause of mortality differences between Black and White individuals in the US, the association between parental incarceration and cardiovascular risk remains poorly understood.

Objective

To examine the association between parental incarceration during childhood and incident cardiovascular risk in adulthood.

Design, Setting, and Participants

This population-based cohort study included data from waves IV (2008-2009) and V (2016-2018) of the US National Longitudinal Study of Adolescent to Adult Health. Participants represented US adults transitioning from young adulthood to adulthood. Data were analyzed from October 28, 2021, to May 1, 2023.

Main Outcomes and Measures

Parental incarceration was defined as a parent or parent-like figure going to jail or prison when participants were aged younger than 18 years. Outcome measures included self-reported diagnoses of obesity, hyperlipidemia, hypertension, diabetes, or heart disease as well as serum elevations in non-high-density lipoprotein cholesterol (≥160 mg/dL) and high-sensitivity C-reactive protein (hsCRP >3 mg/L), a marker of inflammation used to estimate risk of future coronary events. Using sampling weights, incident development of each outcome was modeled as a function of parental incarceration, adjusting for participant- and neighborhood-level characteristics.

Results

This study included 9629 participants representing 16 077 108 US adults. Approximately half of participants were women (5498 [weighted 50.3%]) and the majority (5895 [weighted 71.4%]) were White. The mean participant age was 37.8 years (95% CI, 37.5 to 38.0 years) in wave V compared with 28.9 years (95% CI, 28.6 to 29.1 years) in wave IV. In wave V, those with childhood exposure to parental incarceration had lower educational attainment (91 [weighted 8.2%] vs 245 [weighted 4.2%] completing less than high school), had higher rates of public insurance (257 [weighted 20.6%] vs 806 [weighted 11.0%]), and were disproportionately Black (374 [weighted 22.5%] vs 1488 [weighted 13.6%]). Parental incarceration was associated with 33% higher adjusted odds (95% CI, 1.05 to 1.68) of developing hypertension and 60% higher adjusted odds (95% CI, 1.03 to 2.48) of developing elevated hsCRP. Associations between childhood parental incarceration and other diagnoses (ie, obesity, hyperlipidemia, diabetes, or heart disease) and serum lipid levels were not observed.

Conclusions and Relevance

In this cohort study of US adults transitioning from young adulthood to adulthood, an increased incidence of hypertension and high-risk hsCRP, but not other cardiovascular risk factors, was observed among those exposed to parental incarceration during childhood. These findings suggest possible transgenerational health consequences of mass incarceration.

Age-specific association of stage of hypertension at diagnosis with cardiovascular and all-cause mortality among elderly patients with hypertension: a cohort study

BACKGROUND

Hypertension affects 31.1% of adults worldwide, with higher prevalence of great than 60% in elderly. Advanced hypertension stage was associated with the higher risk of mortality. However, little is known about the age-specific association of stage of hypertension at diagnosis on cardiovascular mortality or all-cause mortality. Therefore, we aim to explore this age-specific association among the hypertensive elderly through stratified and interaction analyses.

METHODS

This cohort study included 125,978 elderly hypertensive patients aged 60+ years from Shanghai of China. Cox regression was used to estimate the independent and joint effect of hypertension stage and age at diagnosis on cardiovascular and all-cause mortality. Interactions were evaluated both additively and multiplicatively. Multiplicative interaction was examined by the Wald test of the interaction term. Additive interaction was assessed by relative excess risk due to interaction (RERI). All analyses were performed stratified by sex.

RESULTS

28,250 patients died during the follow-up up to 8.85 years, and 13,164 died of cardiovascular events. Older age and advanced hypertension stage were risk factors of cardiovascular mortality and all-cause mortality. Besides, smoking, rarely exercise, BMI < 18.5 and diabetes were also the risk factors. When we compared stage 3 hypertension with stage 1 hypertension, hazard ratios (95% confidence interval) of cardiovascular mortality and all-cause mortality were 1.56(1.41-1.72) and 1.29(1.21-1.37) for males aged 60-69 years, 1.25(1.14-1.36) and 1.13(1.06-1.20) for males aged 70-85 years, 1.48(1.32-1.67) and 1.29(1.19-1.40) for females aged 60-69 years, and 1.19(1.10-1.29) and 1.08(1.01-1.15) for females aged 70-85 years, respectively. Negative multiplicative interaction and positive additive interaction between age at diagnosis and stage of hypertension at diagnosis on cardiovascular mortality were observed in males (HR: 0.81, 95% CI: 0.71-0.93 RERI: 0.59, 95% CI: 0.09-1.07) and females (HR: 0.81, 95% CI: 0.70-0.93 RERI: 0.66, 95% CI: 0.10-1.23).

CONCLUSIONS

Diagnosed with stage 3 hypertension was associated with higher risks of cardiovascular mortality and all-cause mortality, which were stronger among patients with age at diagnosis of 60-69 years compared with those with age at diagnosis of 70-85 years. Therefore, for the younger part of the elderly, the Department of Health should pay more attention to treating patients with stage 3 hypertension.

Suboptimal control status of young hypertensive population

The prevalence of hypertension (HT) among young adults aged 18 to 39 years is estimated to be 3.7% to 8.6% worldwide. Although the prevalence of HT in young adults is lower than that of the overall population, those with HT are at substantially increased risk of cardiovascular events compared to those without HT. HT in young adults should be taken with even more caution as longer exposure to higher blood pressure leads to a higher lifetime risk of HT-mediated organ damage. However, young patients with HT show low awareness of HT compared to older patients. Also, they are more prone to show low treatment adherence despite the good efficacy of the treatment. Other risk factors that hinder HT control among young adults include alcohol intake, smoking, low physical activity, emotional stress, job stress, metabolic syndrome, and obesity. This review aimed to illustrate the suboptimal control status of the young hypertensive population and to propose strategies for improvement.

Impact of hypertension diagnosis on morbidity and mortality: a retrospective cohort study in primary care

BACKGROUND

Hypertension is responsible for a huge burden of disease. The aim of this study was to evaluate the impact of newly diagnosed hypertension on the occurrence of kidney or cardiovascular events (K/CVEs) and on mortality among community dwellers.

METHODS

Retrospective cohort study, conducted from January, 2007, to December, 2018. All patients (age > 18) newly diagnosed with hypertension and no previous K/CVEs in 2007 and 2008, in the primary care centers of Madrid (Spain) (n = 71,770), were enrolled. The control group (n = 72,946) included patients without hypertension, matched by center, sex and age. The occurrence of kidney or CV events, including mortality from these causes and total mortality were evaluated using Cox regression and multistate models. Data were collected from three sources: personal data from administrative records, clinical data from medical records, and mortality data from regional and national databases.

RESULTS

The median follow-up was 138.61 months (IQR: 124.68-143.97 months). There were 32,896 K/CVEs (including 3,669 deaths from these causes) and 12,999 deaths from other causes. Adjusted for sex, smoking, diabetes and socioeconomic status, K/CVEs HR was 4.36 (95% CI: 3.80-5.00) for diagnoses before 45 years of age, 2.45(95% CI: 2.28- 2.63) for diagnosis between 45 to 54 years, and HR decreased to 1.86 (95% CI: 1.64-210) for diagnoses over age 85. Total mortality risk was only higher for hypertension diagnosed before 55 years of age (HR: 2.47, 95% CI: 1.90-3.19 for ages 18 to 44; and HR: 1.14, 95% CI: 1.02-1.28 for ages 45 to 54).

CONCLUSION

The diagnosis of hypertension in the community environment, in patients without evidence of previous kidney or CV disease, is associated with a large increase in the risk of K/CVEs, but especially in individuals diagnosed before the age of 55. This diagnosis is only associated with an increase in kidney or cardiovascular mortality or overall mortality when it occurs before age 55.

Age-Dependent Association Between Modifiable Risk Factors and Incident Cardiovascular Disease

Background There have been limited data examining the age-dependent relationship of wide-range risk factors with the incidence of each subtype of cardiovascular disease (CVD) event. We assessed age-related associations between modifiable risk factors and the incidence of CVD. Methods and Results We analyzed 3 027 839 participants without a CVD history enrolled in the JMDC Claims Database (mean age, 44.8±11.0 years; 57.6% men). Each participant was categorized as aged 20 to 49 years (n=2 008 559), 50 to 59 years (n=712 273), and 60 to 75 years (n=307 007). Using Cox proportional hazards models and the relative risk reduction, we identified associations between risk factors and incident CVD, consisting of myocardial infarction, angina pectoris, stroke, and heart failure (HF). We assessed whether the association of risk factors for developing CVD would be modified by age category. Over a mean follow-up of 1133 days, 6315 myocardial infarction, 56 447 angina pectoris, 28 079 stroke, and 56 369 HF events were recorded. The incidence of myocardial infarction, angina pectoris, stroke, and HF increased with age category. Hazard ratios of obesity, hypertension, and diabetes in the multivariable Cox regression analyses for myocardial infarction, angina pectoris, stroke, and HF decreased with age category. The relative risk reduction of obesity, hypertension, and diabetes for CVD events decreased with age category. For example, the relative risk reduction of hypertension for HF decreased from 59.2% in participants aged 20 to 49 years to 38.1% in those aged 60 to 75 years. Conclusions The contribution of modifiable risk factor to the development of CVD is greater in younger compared with older individuals. Preventive efforts for risk factor modification may be more effective in younger people.

In the prevention of dementia, the focus should be on early and consistent treatment of hypertension

The brain is among the target organs of hypertension. Patients with hypertension have a higher risk of developing stroke as well as experiencing a decline in cognitive functions and dementia. Changes in the white matter and atrophy of the grey matter of the brain induced by high blood pressure develop insidiously since the onset of hypertension, even in young individuals. The effect of high blood pressure on the vessel wall cumulates in time; therefore, hypertension in younger people implies an increased risk of dementia in older age. Hypertension in young age cannot be considered a benign condition. Hypertension in middle age increases the risk of dementia by 61 %. Consistent and early hypertension control can reverse the adverse development towards dementia and lack of self-sufficiency in the patient. Data comparing individual antihypertensive drugs in terms of preventing dementia are scarce. However, renin angiotensin system blockers have been found to protect against Alzheimer's disease more than other classes of antihypertensive drugs. To achieve rapid and effective hypertension control, a combination of antihypertensive drugs is usually required. Using a fixed-dose triple combination of perindopril, indapamide, and amlodipine, blood pressure targets of < 130/80 mm Hg can be achieved within three months in 93 % of patients.

Influence of hypertension duration and blood pressure levels on cardiovascular disease and all-cause mortality: A large prospective cohort study

Background and objects

A longer duration of hypertension (HTN) has been suggested to be associated with a greater risk of cardiovascular disease (CVD). Whether such an association is similar for mortality risk, and whether HTN duration is associated with CVD/mortality beyond blood pressure (BP) control levels are yet to be assessed. We aimed to examine the associations of HTN duration and the combination of HTN duration and systolic blood pressure (SBP)/diastolic blood pressure (DBP) with risks of CVD and all-cause mortality.

Methods

We used data on ∼450,000 UK residents. Participants were categorized by HTN status and HTN duration. The primary outcome was a composite of non-fatal myocardial infarction, non-fatal stroke and CVD death. We also explored the results for the above-mentioned CVD outcomes separately. All-cause mortality was also used as a secondary outcome. The age at HTN diagnosis was obtained by self-report. HTN duration was calculated as baseline age minus age at diagnosis.

Results

Among all participants, compared with non-hypertensive participants, those with a longer HTN duration had increased risks of CVD and all-cause mortality. These associations persisted among hypertensive patients. Specifically, compared with patients with HTN durations of < 5 y, patients with a HTN duration of 5 to < 10 y, 10 to < 15 y, and ≥ 15 y had adjusted HRs (95% CI) of 1.09 (1.03, 1.17), 1.21 (1.13, 1.31), and 1.38 (1.29, 1.48) for composite CVD (P-trend < 0.001); and 1.03 (0.97, 1.08), 1.09 (1.02, 1.16), and 1.17 (1.11, 1.24) for all-cause mortality (P-trend < 0.001). When compared with hypertensive patients with BP < 140/90 mmHg and a HTN duration of < 5 y, adjusted HRs of CVD and all-cause mortality were 1.35 (1.15, 1.57) and 1.26 (1.11, 1.42) for those with BP < 140/90 mmHg and a duration of ≥ 15 y, and 1.43 (1.26, 1.60) and 1.13 (1.03, 1.25) for those with BP ≥ 140/90 mmHg and durations of ≥ 15 y, respectively.

Conclusion

A longer HTN duration was associated with increased risks of CVD and overall death in a linear fashion, and these associations were independent of BP control levels.

Association between Age of Onset of Hypertension and Incident Atrial Fibrillation

We investigated whether age at hypertension (HTN) onset was associated with the risk of atrial fibrillation (AF) in the general population. This prospective longitudinal community-based cohort study included 9892 participants without AF at baseline, who underwent biennial electrocardiography for a median duration of 11.5 years. The participants were divided into five groups, consisting of a normotensive group (Group-N) and four HTN groups based on HTN onset age: <45 years (Group-H1); 45−54 years (Group-H2); 55−64 years (Group-H3); and ≥65 years (Group-H4). A multivariate Cox proportional hazards model showed that the presence of HTN at baseline was associated with higher AF risk (hazard ratio [HR], 1.93; 95% confidence interval [CI] 1.32−2.80). The participants in Group-H1 had the highest risk of AF (HR 3.18; CI 1.74−5.82), and the risk of AF decreased as HTN onset age increased across the four HTN groups (p for trend = 0.014). The AF onset age was significantly younger in participants in Group-H1 than in Groups-H2−H4. Early-onset HTN was associated with an increased risk of AF, and younger onset of AF in the general population. Surveillance for AF should be considered at a younger age in individuals with HTN.

Apparent Treatment-Resistant Hypertension Across the Spectrum of Heart Failure Phenotypes in the Swedish HF Registry

BACKGROUND

Hypertension is common in patients with heart failure (HF), but less is known about resistant hypertension.

OBJECTIVES

This study sought to investigate apparent treatment-resistant hypertension (aTRH) in patients with HF in the SwedeHF (Swedish Heart Failure Registry), across the spectrum of HF phenotypes (heart failure with reduced ejection fraction [HFrEF], heart failure with mildly reduced ejection fraction [HFmrEF], and heart failure with preserved ejection fraction [HFpEF]).

METHODS

aTRH was defined as systolic blood pressure ≥140 mm Hg (≥135 mm Hg in diabetes) despite treatment with an angiotensin-converting enzyme inhibitor, angiotensin receptor blocker, or sacubitril-valsartan, as well as a calcium-channel blocker and a diuretic; non-treatment-resistant hypertension (TRH) was defined as systolic blood pressure above these thresholds but not on the 3-drug combination; and normal blood pressure was defined as under these thresholds. In each left ventricular ejection fraction (LVEF) category, patient factors associated with aTRH and non-TRH and outcomes (HF hospitalization and cardiovascular death composite, its components, and all-cause death) according to hypertension category were examined.

RESULTS

Among 46,597 patients, aTRH was present in 2,693 (10%), 1,514 (14%), and 1,450 (17%) patients with HFrEF, HFmrEF, and HFpEF, respectively. Older age, obesity, diabetes, and kidney disease were associated with a greater likelihood of aTRH and non-TRH (vs normal blood pressure). Associations were generally similar irrespective of LVEF category. Compared with normal blood pressure, aTRH was associated with a lower adjusted risk of the composite outcome in HFrEF and HFmrEF (HR: 0.79 [95% CI: 0.74-0.85] and HR: 0.86 [95% CI: 0.77-0.96]) but not in HFpEF (HR: 0.93 [95% CI: 0.84-1.04]).

CONCLUSIONS

aTRH was most common in HFpEF and least common in HFrEF. Associated patient characteristics were similar irrespective of LVEF category. aTRH (vs normal blood pressure) was associated with a lower risk of first HF hospitalization or cardiovascular death in HFrEF and HFmrEF but not in HFpEF.

Development and Validation of Prediction Models for Hypertensive Nephropathy, the PANDORA Study

Importance

Hypertension is a leading cause of end-stage renal disease (ESRD), but currently, those at risk are poorly identified.

Objective

To develop and validate a prediction model for the development of hypertensive nephropathy (HN).

Design, Setting, and Participants

Individual data of cohorts of hypertensive patients from Kailuan, China served to derive and validate a multivariable prediction model of HN from 12, 656 individuals enrolled from January 2006 to August 2007, with a median follow-up of 6.5 years. The developed model was subsequently tested in both derivation and external validation cohorts.

Variables

Demographics, physical examination, laboratory, and comorbidity variables.

Main Outcomes and Measures

Hypertensive nephropathy was defined as hypertension with an estimated glomerular filtration rate (eGFR) &lt; 60 ml/min/1.73 m2 and/or proteinuria.

Results

About 8.5% of patients in the derivation cohort developed HN after a median follow-up of 6.5 years that was similar in the validation cohort. Eight variables in the derivation cohort were found to contribute to the risk of HN: salt intake, diabetes mellitus, stroke, serum low-density lipoprotein, pulse pressure, age, hypertension duration, and serum uric acid. The discrimination by concordance statistics (C-statistics) was 0.785 (IQR, 0.770-0.800); the calibration slope was 1.129, the intercept was –0.117; and the overall accuracy by adjusted R2 was 0.998 with similar results in the validation cohort. A simple points scale developed from these data (0, low to 40, high) detected a low morbidity of 7% in the low-risk group (0–10 points) compared with &gt;40% in the high-risk group (&gt;20 points).

Conclusions and Relevance

A prediction model of HN over 8 years had high discrimination and calibration, but this model requires prospective evaluation in other cohorts, to confirm its potential to improve patient care.

Approach to Hypertension in Adolescents and Young Adults

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.

Correlation of Coronary Artery Disease and Left Ventricular Hypertrophy

Ischemic heart disease (IHD) is the leading cause of death worldwide, and it is defined as an imbalance between myocardial oxygen supply and demand. Coronary artery disease (CAD) and left ventricular hypertrophy (LVH) are two common causes of IHD that independently result in myocardial ischemia. CAD decreases myocardial blood and oxygen supply whereas LVH increases myocardial oxygen demand. The coexistence of both CAD and LVH results in a significant increase in oxygen demand while simultaneously lowering oxygen supply.

Since hypertension is a shared predisposing condition for both CAD and LVH, the left ventricular (LV) mass on noninvasive echocardiography can reflect on the severity of coronary artery stenosis. In clinical practice, it can help physicians decide whether to perform invasive cardiac catheterization to visualize the extent of the coronary block. Although, both CAD and LVH are directly proportional to mortality risk, the addition of eccentric LVH can further increase morbidity and mortality due to myocardial infarction. Therefore, the latest management of both the acute and chronic phases of CAD places an increased emphasis on controlling the predisposing factors to prevent or reverse LVH. For example, angiotensin-converting enzyme inhibitors and diuretics reduce LV mass by lowering the cardiac preload and afterload. This article aims to investigate the deleterious effects of the collaboration between CAD and LVH, establish a causal relationship, and explore the new prevention and management strategies.

Clinical Correlates of Early-Onset Hypertension

BACKGROUND

Early-onset hypertension has been established as a heritable trait and a risk factor for cardiovascular disease outcomes. However, the clinical correlates of early-onset hypertension remain unidentified.

METHODS

In this study, we assessed the demographic characteristics and lifestyle factors related to hypertension onset age in a sample of 3,286 Coronary Artery Risk Development in Young Adults (CARDIA) study participants (mean baseline age 25 ± 4 years, 57% women). We examined the association between the participants’ baseline characteristics and age of hypertension onset subgroups (<35, 35‒44, or ≥45 years) using a multinomial logistic regression model with those who did not develop hypertension as the reference group. Hypertension onset was defined as blood pressure ≥140/90 mm Hg or antihypertensive medication use on 2 consecutively attended follow-up visits.

RESULTS

In the multinomial logistic regression model, individuals who were black (odds ratio [OR], 5.08; 95% confidence interval [CI], 3.17–8.14), were more obese (OR, 1.57; 95% CI, 1.32–1.88), or had higher total cholesterol (OR, 1.34; 95% CI, 1.13–1.60 per SD) had increased odds of early-onset hypertension (onset at <35 years) vs. not developing hypertension. In contrast, 1-SD higher high-density lipoprotein (HDL)-cholesterol was related to decreased odds of early-onset hypertension (OR, 0.71; 95% CI, 0.57–0.89). The odds for having earlier hypertension onset increased linearly across age of onset categories in black individuals and individuals with lower HDL-cholesterol (P < 0.05 for trend for both).

CONCLUSIONS

Our findings suggest that individuals who are black, obese, have higher total cholesterol, or have lower HDL-cholesterol level, are potentially at an increased risk of having early-onset hypertension.

Body Mass Index Trajectories during 6-18 Years Old and the Risk of Hypertension in Young Adult: A Longitudinal Study in Chinese Population

Background

Overweight/obesity in childhood is suggested to increase the risk of hypertension later in life. We aimed to assess whether and how body mass index (BMI) trajectories during 6–18 years of age are associated with hypertension in young adulthood (18–37 years) in the Chinese population.

Methods

Based on the China Health and Nutrition Survey (CHNS), a total of 1,872 participants who received ≥2 measurements of BMI during 6–18 years and had assessment of blood pressure (BP) in young adulthood were included. BMI trajectories were explored using latent class growth mixture models, and associations between identified trajectories with hypertension in young adulthood were examined by logistic regression analyses.

Results

Five heterogeneous BMI trajectories were identified: the low slow-increasing (20.03%), low moderate-increasing (56.14%), low rapid-increasing (17.04%), moderate-increasing (3.63%), and elevated-decreasing (3.15%) groups. Compared with the low slow-increasing group, another three increasing groups had gradually elevated risk of hypertension, yielding maximally adjusted odds ratio (95% confidence interval) (OR (95% CI)) of 2.48 (1.39–4.42), 3.24 (1.66–6.31), and 3.28 (1.19–9.08), respectively, whereas the elevated-decreasing group reversed overweight/obesity to normal weight in childhood, rendering its association with hypertension as not statistically significant (OR (95% CI) = 2.74 (0.98–7.65)).

Conclusion

Our study indicates that there are varied BMI trajectories from childhood to adulthood and that an elevated BMI trajectory during childhood is related with an increased risk of hypertension in young adulthood. In contrast, weight loss of children with high initial BMI may mitigate or reverse the risk. Our findings emphasize the importance of BMI continuous monitoring during early life.

Blood Pressure in Young Adults and Cardiovascular Disease Later in Life

Cardiovascular disease (CVD) mortality has declined markedly over the past several decades among middle-age and older adults in the United States. However, young adults (18-39 years of age) have had a lower rate of decline in CVD mortality. This trend may be related to the prevalence of high blood pressure (BP) having increased among young US adults. Additionally, awareness, treatment, and control of hypertension are low among US adults between 20 and 39 years of age. Many young adults and healthcare providers may not be aware of the impact of high BP during young adulthood on their later life, the associations of BP patterns with adverse outcomes later in life, and benefit-to-harm ratios of pharmacological treatment. This review provides a synthesis of the related resources available in the literature to better understand BP-related CVD risk among young adults and better identify BP patterns and levels during young adulthood that are associated with CVD events later in life, and lastly, to clarify future challenges in BP management for young adults.

Low admission blood pressure as a marker of poor 1-year survival in patients with revascularized critical limb ischemia

OBJECTIVE

To contrast the association between blood pressure (BP) level and antihypertensive medications at hospital admission with 1-year mortality in patients undergoing revascularization for critical limb ischemia (CLI).

METHODS

From November 2013 to May 2019, 315 consecutive patients were retrospectively included. A median of seven (IQR 3-13) separate readings were recorded for each patient before revascularization procedure and the average represented patient's mean BP. BP-lowering medications, clinical and biological parameters were recorded at baseline. The main outcome was total 1-year mortality.

RESULTS

The cohort included 172 men (55%) and 143 women (45%), with a mean age of 77.9 ± 11.9 years. Treated hypertension was present in 245 (78%) patients; 288 (91%) patients had BP-lowering drug prescriptions (2.1 ± 1.3 medications at baseline). Mean SBP, DBP, mean BP (MBP) and pulse pressure (PP) were 132 ± 18, 70 ± 8, 90 ± 10 and 62 ± 16mmHg. During 1-year follow-up, 80 (25.4%) patients died. In single-pressure multivariate analysis, SBP (hazard ratio 0.97; 95% CI 0.96-0.99; P = 0.005), MBP (hazard ratio 0.96; 95% CI 0.92-0.99; P = 0.01), PP (hazard ratio 0.97; 95% CI 0.95-0.99; P = 0.009), but not DBP, were inversely correlated with 1-year mortality, independently of age, coronary heart disease, left ventricular ejection fraction, brain natriuretic peptide, serum albumin, institutionalized status and antihypertensive drugs. Association between SBP, MBP and PP with 1-year mortality had a quite linear reverse pattern.

CONCLUSION

Among patients undergoing revascularization for CLI, there is an inverse correlation between admission SBP, MBP and PP with 1-year mortality. BP may represent a modifiable therapeutic target to prevent poor outcome in CLI patients.

Association of Age of Onset of Hypertension With Cardiovascular Diseases and Mortality

BACKGROUND

The relations of hypertension onset age with cardiovascular diseases (CVD) and all-cause mortality remain inconclusive.

OBJECTIVES

This study sought to examine the associations of hypertension onset age with CVD and all-cause mortality.

METHODS

This prospective study included 71,245 participants free of hypertension and CVD in the first survey (July 2006 to October 2007) of the Kailuan study, a prospective cohort study in Tangshan, China. All participants were followed biennially until December 31, 2017. A total of 20,221 new-onset hypertension cases were identified during follow-up. We randomly selected 1 control participant for each new-onset hypertensive participant, matching for age (±1 year) and sex, and included 19,887 case-control pairs. We used weighted Cox regression models to calculate the average hazard ratios of incident CVD and all-cause mortality across the age groups.

RESULTS

During an average follow-up of 6.5 years, we identified 1,672 incident CVD cases and 2,008 deaths. After multivariate adjustment, with the increase in hypertension onset age, the hazards of outcomes were gradually attenuated. The average hazard ratio (95% confidence interval) of CVD and all-cause mortality were 2.26 (1.19 to 4.30) and 2.59 (1.32 to 5.07) for the hypertension onset age <45 years old group, 1.62 (1.24 to 2.12) and 2.12 (1.55 to 2.90) for the 45- to 54-year age group, 1.42 (1.12 to 1.79) and 1.30 (1.03 to 1.62) for the 55- to 64-year age group, and 1.33 (1.04 to 1.69) and 1.29 (1.11 to 1.51) for the ≥65-year age group, respectively (p for interaction = 0.38 for CVD and <0.01 for death).

CONCLUSIONS

Hypertension was associated with a higher risk for CVD and all-cause mortality, and the associations were stronger with a younger age of onset.

Mechanisms of Vascular Remodeling in Hypertension

Hypertension is both a cause and a consequence of central artery stiffening, which in turn is an initiator and indicator of myriad disease conditions and thus all-cause mortality. Such stiffening results from a remodeling of the arterial wall that is driven by mechanical stimuli and mediated by inflammatory signals, which together lead to differential gene expression and concomitant changes in extracellular matrix composition and organization. This review focuses on biomechanical mechanisms by which central arteries remodel in hypertension within the context of homeostasis-what promotes it, what prevents it. It is suggested that the vasoactive capacity of the wall and inflammatory burden strongly influence the ability of homeostatic mechanisms to adapt the arterial wall to high blood pressure or not. Maladaptation, often reflected by inflammation-driven adventitial fibrosis, not just excessive intimal-medial thickening, significantly diminishes central artery function and disturbs hemodynamics, ultimately compromising end organ perfusion and thus driving the associated morbidity and mortality. It is thus suggested that there is a need for increased attention to controlling both smooth muscle phenotype and inflammation in hypertensive remodeling of central arteries, with future studies of the often adaptive response of medium-sized muscular arteries promising to provide additional guidance.

Association between self-reported hypertension onset age and electrocardiographic left ventricular hypertrophy

Objectively defined early-onset hypertension, based on repeated blood pressure measurements, is associated with greater odds of organ damage and cardiovascular mortality than late-onset hypertension. In this study we examined the association between two factors that are easily available in primary care, self-reported hypertension onset age and electrocardiographic left ventricular hypertrophy (ECG-LVH), in a nationwide population sample of 2864 Finns aged ≥50 years. We observed that, in contrast to prior findings, the odds of ECG-LVH were similar between self-reported hypertension onset age groups, and thus self-reported early-onset hypertension does not seem to associate with ECG-LVH more strongly than simple presence of hypertension.

Hypertension (Blood Pressure) and Lifetime Risk of Target Organ Damage

PURPOSE OF REVIEW

The purpose of this review is to describe the long-term or lifetime relationship between blood pressure and target organ damage. The use of the term "blood pressure" as opposed to hypertension is purposeful. The risk of cardiovascular disease from blood pressure begins below the levels of blood pressure defined as hypertension by contemporary definitions.

RECENT FINDINGS

An important recent publication that bears on this topic was the 2017 ACC/AHA Blood Pressure Management Guidelines. The redefinition of hypertension and blood pressure treatment goal to 130/80 mmHg and the decision to rely almost exclusively on data from event-based randomized controlled clinical trials, which led to a recommendation for lifestyle therapy only for most with stage 1 hypertension, were important. A report from the CARDIA study demonstrated significant risk for cardiovascular disease at 20 years for stage 1 hypertension. Based on all evidence, clinicians should consider the use of medication for stage 1 hypertension in those uncontrolled on lifestyle therapy.

Age of Hypertension Onset: Overview of Research and How to Apply in Practice

PURPOSE OF REVIEW

To review the current evidence on research related to age of hypertension onset-its definition, correlates, heritability, and association with adverse outcomes. We also propose a framework for implementing assessment of hypertension onset age into clinical practice.

RECENT FINDINGS

Prior studies have used both objective measurements and self-report to determine age of hypertension onset or early-onset hypertension. Yet, no criterion for standard definition currently exists for either. Data from epidemiological and clinical studies demonstrate that early-onset hypertension is a highly heritable trait that confers an increased risk for cardiovascular death and end-organ damage compared with late-onset hypertension. Literature to date suggests that (parental) age of hypertension onset can be feasibly assessed for estimating (1) risk of future hypertension in non-hypertensive persons; and (2) the propensity for cardiovascular disease in individuals with established hypertension.

Self-reported Age of Hypertension Onset and Hypertension-Mediated Organ Damage in Middle-Aged Individuals

Background

Objectively defined early onset hypertension, based on repeated blood pressure measurements, is a strong risk factor for cardiovascular disease (CVD). We aimed to assess if also self-reported hypertension onset age is associated with hypertension-mediated organ damage (HMOD). Additionally, we evaluated the agreement between self-reported and objectively defined hypertension onset age.

Methods

We studied 2,649 participants (50 ± 4 years at the time of outcome assessment, 57% women) of the Coronary Artery Risk Development in Young Adults (CARDIA) study who underwent measurements for echocardiographic left ventricular hypertrophy (LVH), left ventricular diastolic dysfunction (LVDD), coronary calcification, and albuminuria. We divided the participants into groups according to self-reported hypertension onset age (<35 years, 35–44 years, ≥45 years, and no hypertension). We used multivariable-adjusted logistic regression models to assess the relation between self-reported hypertension onset age with the presence of HMOD, with those who did not report hypertension as the referent group.

Results

Compared with individuals without self-reported hypertension, self-reported hypertension onset at <35 years was associated with LVH (odds ratio (OR), 2.38; 95% confidence interval (CI), 1.51–3.76), LVDD (OR, 2.32; 95% CI, 1.28–4.18, coronary calcification (OR, 2.87; 95% CI, 1.50–5.47), and albuminuria (OR, 1.62; 95% CI, 0.81–3.26). Self-reported hypertension onset at ≥45 years was only associated with LVDD (OR, 1.81; 95% CI, 1.06–3.08). The agreement between self-reported and objectively defined hypertension onset age groups was 78–79%.

Conclusions

Our findings suggest that self-reported hypertension onset age, a pragmatically feasible assessment in clinical practice, is a reasonable method for assessing risk of HMOD and CVD.
