Patients diagnosed with hypertension (HT) are at high risk for end-organ damage. With changing living conditions and access to healthcare facilities worldwide, the rate of diagnosis in childhood is increasing. In this study, healthy children were compared with a group of pediatric patients diagnosed with hypertension. Cardiac findings in the hypertensive group were compared at presentation and at six months. We aimed to determine the discriminatory value of epicardial adipose tissue (EAT) measurements as an early imaging marker for cardiac involvement in children with HT compared to healthy children and to determine its prognostic feature for HT treatment response.
Methods:
Fifty-nine primary hypertension patients and 76 control patients aged 0-18 years were compared. EAT values measured between the healthy group and the patient group and at the beginning of treatment and subsequent follow-ups in the patient group were evaluated with M-mode measurements.
Results:
There was no difference between the groups in terms of sex, and age. EAT was found to be significantly higher in the patient group than in the healthy group. There was a statistically significant difference between the EAT measurements evaluated before and after treatment in the patient group.
Conclusions:
Hypertension is an important cause of morbidity and mortality. Using EAT measurements as a noninvasive parameter may provide information about early cardiac involvement due to HT. EAT is promising as an imaging marker that can be used in diagnosis and follow-up.
Noradrenergic activation in the central and peripheral nervous systems is a putative mechanism explaining the link between hypertension and affective disorders.
Aims
We investigated whether these stress-sensitive comorbidities may be dependent on basal noradrenergic activity and whether vascular responses to centrally acting stimuli vary according to noradrenergic activity.
Method
We examined the relation of affective disorders and stress-mediated vascular responses to plasma concentrations of normetanephrine, a measure of noradrenergic activity, in subjects with primary hypertension (n = 100, mean ± s.d. age 43 ± 11 years, 54% male). The questionnaires Patient Health Questionnaire-9 (PHQ-9), 16-item Quick Inventory of Depressive Symptomatology-Self Report (QIDSSR-16) and Generalized Anxiety Disorder-7 (GAD-7) were used for evaluation of symptoms of depression and anxiety. Forearm blood flow (strain gauge plethysmography) was used to assess vascular responses to mental stress and to device-guided breathing (DGB), interventions that respectively increase or decrease noradrenergic activity in the prefrontal cortex and locus coeruleus.
Results
Low mood and high anxiety were two- to threefold higher for hypertensive subjects in the highest compared with the lowest normetanephrine tertiles (each P < 0.005). Forearm vasodilator responses to mental stress and vasoconstrictor responses to DGB were attenuated in those with high compared with low normetanephrine (28.3 ± 21% v. 47.1 ± 30% increases for mental stress and 3.7 ± 21% v. 18.6 ± 15% decreases for DGB for highest versus lowest tertiles of normetanephrine, each P ≤ 0.01).
Conclusions
A hyperadrenergic state in hypertension is associated with mood disturbance and impaired stress-modulated vasomotor responses. This association may be mediated by chronic stress impinging on pathways regulating central arousal and peripheral sympathetic nerve activity.
Passive smoking is associated with an increased risk of hypertension in children. Antioxidant nutrients are known to alleviate oxidative stress, a key factor in the development of hypertension. Riboflavin, with its antioxidant properties, may help mitigate oxidative damage caused by passive smoke exposure. This study aimed to examine whether riboflavin intake could influence the relationship between passive smoking and hypertension in children and adolescents aged 6–19 years. Data were extracted from the 2007–2018 National Health and Nutrition Examination Survey. Weighted logistic regression models were used to identify potential covariates, and weighted multiple logistic regression models assessed the associations between passive smoking, riboflavin intake and hypertension. The association was also investigated in diverse age, gender and race subgroups. Results were presented as OR and 95 % CI. A total of 11 445 children and adolescents with a mean age of 12·89 (0·06) years were included. After adjusting covariates, cotinine ≥ 0·05 ng/ml was associated with increased odds of hypertension (OR = 1·20, 95 % CI: 1·06, 1·36). When individuals had a riboflavin intake < 1·87 mg, passive smoking (OR = 1·98, 95 % CI: 1·25, 3·13) and active smoking (OR = 1·69, 95 % CI: 1·14, 2·51) were both related to higher odds of hypertension. When individuals had a riboflavin intake ≥ 1·87 mg, no association was observed between passive smoking (OR = 0·83, 95 % CI: 0·48, 1·44) and active smoking (OR = 1·05, 95 % CI: 0·68, 1·62) and hypertension. Riboflavin intake may modulate the association between smoking status and hypertension in children and adolescents aged 6–19 years. The moderating effect was also found in age < 13 years old, ≥ 13 years old, males and non-Hispanic Whites.

This chapter covers drugs affecting the cardiovascular system in three distinct sections. Firstly we discuss antihypertensive agents, those used in anaesthesia and critical care, and those used in the community. We then go on to discuss antiarrhythmic agents and the Vaughan-Williams classification, with additional focus on digoxin and amiodarone. Finally we discuss inotropic and vasopressor drugs, both essential knowledge for the exam and clinical practice.
The purpose of this study was to report on the prevalence of hypertension and anaemia, and types of medications prescribed to expectant mothers attending antenatal clinics at Intermediate Hospital Katutura in Windhoek, Namibia.
Background:
Millennium Development Goals 4 and 5 speak to reduction of child mortality and improvement of maternal health by 2015, respectively. Gestational hypertension is a major contributor to maternal and perinatal mortality and is reported to affect up to 10% of women world-wide. Prevalence of anaemia among pregnant women is reported higher in low- and middle-income countries than in developed countries.
Methods:
This was a cross-sectional study involving the review of outpatient and clinic health records for patients attending antenatal clinics at Intermediate Hospital Katutura, Windhoek during October to November 2022. Data for patients on first antenatal clinic visit were obtained from facility antenatal clinic patient registers while that of follow-up patients were from patient health passports. All expectant mothers over 18 years of age who had provided written consent to participate, were included. Data collected were: age, body weight, haemoglobin concentration, blood pressure, gravida, number of babies delivered, pregnancy stage, comorbidities, and prescribed medications. The results were summarised using descriptive statistics. A p-value <0.05 is considered to be statistically significant.
Findings:
354 records were included: 303 (85.6%) first visit, and 51 follow-up (14.4%). There was a significant correlation between systolic blood pressure (BP) and body weight (r = 0.31, p < 0.001). 13.5% of first-time visitors had haemoglobin levels lower than the normal range (11 g/dL). Difference in haemoglobin levels between trimesters 1 and 3 were significant (p < 0.001). Methyldopa was prescribed for all hypertensive expectant mothers. To reduce the incidences of anaemia and hypertension during pregnancy, women of childbearing age should be encouraged to attend antenatal visits earlier in pregnancy and to take measures for body weight reduction, respectively.
Hypertension disorders of pregnancy are a clinical spectrum that includes gestational hypertension, preeclampsia, and eclampsia. Hypertensive disorders are a common cause of significant maternal and fetal morbidity and mortality. Therefore, it is important for women’s health clinicians to be knowledgeable of the diagnostic criteria and management guidelines. A 25-year-old gravida 3 para 0 at 35 weeks’ gestation presents with a blood pressure of 165/95, proteinuria, and develops seizures. Based on her clinical presentation, physical examination, and laboratory findings, a diagnosis of eclampsia was made. The patient was promptly stabilized, treated with magnesium sulfate for seizure prophylaxis, received antihypertensive treatment, and delivered in a timely manner. The case highlights the recommended maternal evaluation, fetal surveillance, timing of delivery, and treatment for hypertension disorders of pregnancy.
Comorbidities, which are additional health conditions that occur alongside diabetes, can have a significant effect on blood sugar control. These conditions often complicate the management of diabetes and worsen overall health. Malnutrition, on the other hand, is a common concern for people with diabetes due to difficulties with food intake and metabolism. Proper nutrition is crucial for maintaining general health and effectively managing the disease. However, the extent of comorbidities and malnutrition within this group is not well understood in the study area. A cross-sectional study was conducted at Hawassa governmental hospitals between April and May 2023, involving 422 adult outpatients living with diabetes. The study aimed to evaluate their comorbidities, nutritional status, and associated factors. The required data were collected using structured and semi-structured questionnaires. Bivariate and multivariate logistic regression analyses were conducted using SPSS version 25.0. Undernutrition and concordant comorbidities were prevalent in the study population, occurring at rates of 15.2% and 57.8%, respectively. Additionally, 18.5% of participants were classified as overweight and obese with a BMI greater than 25 kg/m2. Three significant predictors of undernutrition among adult outpatients living with diabetes were identified: alcohol intake (P < 0.05), comorbidities (P < 0.01), and educational status (P < 0.05). Concordant comorbidity was notably common in these patients. It is recommended that the healthcare system consider comorbid conditions when managing diabetes. A longitudinal study is suggested to provide stronger evidence on these findings.
While the traditional Japanese diet has been suggested to increase blood pressure due to its high Na content, whether the contemporary Japanese diet is associated with blood pressure remains elusive. We developed a traditional Japanese diet score (nine items: white rice, miso soup, soy products, vegetables, mushrooms, seaweeds, fish, salty food and green tea) and a modified version by substituting white rice with whole-grain rice, reverse scoring for salty food and adding fruits, raw vegetables and dairy products using data from 12 213 employees from Japanese companies. Hypertension was defined as a blood pressure of 140/90 mmHg or more or the use of antihypertensive drugs. A multi-level Poisson regression model with a robust variance estimator was used to calculate prevalence ratios (PR) and 95 % CI while adjusting for covariates. The adjusted PR (95 % CI) of hypertension for the lowest through highest quartiles of the traditional Japanese diet score were 1·00 (reference), 0·94 (0·88, 1·02), 0·98 (0·90, 1·06) and 0·96 (0·90, 1·02), respectively (P for trend = 0·29), while those for the modified Japanese diet score were 1·00 (reference), 0·96 (0·94, 0·99), 0·95 (0·85, 1·05) and 0·94 (0·87, 1·01), respectively (P for trend = 0·10). In this cross-sectional study, close adherence to the traditional Japanese diet was not associated with the prevalence of hypertension, whereas there was a suggestion of an inverse association between the modified Japanese diet and the prevalence of hypertension.
We conducted a pilot study of implementing community health workers (CHWs) to assist patients with hypertension and social needs. As part of clinical care, patients identified as having an unmet need were referred to a CHW. We evaluated changes in blood pressure and needs among 35 patients and conducted interviews to understand participants’ experiences. Participants had a mean age of 54.1 years and 29 were Black. Twenty-six completed follow-up. Blood pressure and social needs improved from baseline to 6 months. Participants reported being accepting of CHWs, but also challenges with establishing a relationship with a CHW and being unclear about their role.
This study was designed to explore the mediating role of serum 25-hydroxyvitamin D (25(OH) D) in Triglyceride–glucose (TyG) index and hypertension (HTN). Study participants were selected from the 2001 to 2018 National Health and Nutrition Examination Survey. Firstly, we estimated the association between TyG index and serum 25(OH)D with HTN using a weighted multivariable logistic regression model and restricted cubic spline. Secondly, we used a generalised additive model to investigate the correlation between TyG index and serum 25(OH)D. Lastly, serum 25(OH)D was investigated as a mediator in the association between TyG index and HTN. There were 14 099 subjects in total. TyG index was positively and linearly associated with HTN risk, while serum 25(OH)D had a U-shaped relationship with the prevalence of HTN. When the serum 25(OH)D levels were lower than 57·464 mmol/l, the prevalence of HTN decreased with the increase of serum 25(OH)D levels. When serum 25(OH)D levels rise above 57·464 mmol/l, the risk of HTN increases rapidly. Based on the U-shaped curve, serum 25(OH)D concentrations were divided into two groups: < 57·464 and ≥57·464 mmol/l. According to the mediation analysis, when serum 25(OH)D levels reached < 57·464 mmol/l, the positive association between the TyG index and incident HTN was increased by 25(OH)D. When serum 25(OH)D levels reached ≥ 57·464 mmol/l, the negative association between the TyG index and incident HTN was increased by 25(OH)D. There was a mediation effect between the TyG index and HTN, which was mediated by 25(OH)D. Therefore, we found that the association between serum 25(OH)D levels and TyG index may influence the prevalence of HTN.
Post-traumatic stress disorder (PTSD) and hypertension are highly prevalent among Veterans. Cognitive dispersion, indicating within-person variability across neuropsychological measures at one time point, is associated with increased risk of dementia. We examined interactive effects of PTSD symptom severity and hypertension on cognitive dispersion among older Veterans.
Methods:
We included 128 Vietnam-era Veterans from the Department of Defense-Alzheimer’s Disease Neuroimaging Initiative (DoD-ADNI) with a history of PTSD. Regression models examined interactions between PTSD symptom severity and hypertension on cognitive dispersion (defined as the intraindividual standard deviation across eight cognitive measures) adjusting for demographics and comorbid vascular risk factors.
Results:
There was an interaction between PTSD symptom severity and hypertension on cognitive dispersion (p = .026) but not on mean cognitive performance (p = .543). Greater PTSD symptom severity was associated with higher cognitive dispersion among those with hypertension (p = .002), but not among those without hypertension (p = .531). Results remained similar after adjusting for mean cognitive performance.
Conclusions:
Findings suggest, among older Veterans with PTSD, those with both hypertension and more severe PTSD symptoms may be at greater risk for cognitive difficulties. Further, cognitive dispersion may be a useful marker of subtle cognitive difficulties. Future research should examine these associations longitudinally and in a diverse sample.
Despite the blaze of advancing knowledge on its complex genetic architecture, hypertension remains an elusive condition. Genetic studies of blood pressure have yielded bitter-sweet results thus far with the identification of more than 2,000 genetic loci, though the candidate causal genes and biological pathways remain largely unknown. The era of big data and sophisticated statistical tools has propelled insights into pathophysiology and causal inferences. However, new genetic risk tools for hypertension are the tip of the iceberg, and applications of genomic technology are likely to proliferate. We review the genomics of hypertension, exploring the significant milestones in our current understanding of this condition and the progress towards personalised treatment and management for hypertension.
To evaluate the relationship between the food environment in favelas and the presence of arterial hypertension and diabetes among women in the context of social vulnerability.
Design:
A cross-sectional and partially ecological population-based study was conducted in a Brazilian capital city. The healthiness and availability of ultra-processed foods in the food environment were assessed through retailer audits using the AUDITNOVA instrument. The presence of diabetes and arterial hypertension was evaluated based on self-reported prior medical diagnosis. Logistic regression models were applied using generalised estimating equations, adjusted for age, education, race/skin colour and poverty status.
Participants:
1882 adult women of reproductive age (20–44 years).
Results:
It was found that 10·9 % of women were hypertensive and 3·2 % had diabetes. The likelihood of having diabetes and arterial hypertension decreases with higher levels of healthiness in the food environment (diabetes (OR: 0·25; 95 % CI: 0·07, 0·97)/arterial hypertension (OR: 0·45; 95 % CI: 0·24, 0·81)) and increases with greater availability of ultra-processed foods in their living area (diabetes (OR: 2·18; 95 % CI: 1·13, 4·21)/arterial hypertension (OR: 1·64; 95 % CI: 1·09, 2·47)).
Conclusions:
These results suggest that characteristics of the consumer food environment have a significant effect on the occurrence of chronic diseases among socially vulnerable women, adding to the existing evidence in the literature and highlighting the need for integrated health care.
In response to increasing hypertension rates, South Africa implemented a regulation which set a maximum total sodium content for certain packaged food categories. We assess changes in reported sodium intake among 18-39 year old adults living in one township in the Western Cape as a result of the implementation of the regulation in 2016.
Design:
By linking one set of 24 hour dietary recall data to two versions of the South Africa Food Composition Database which reflect the pre-regulation and post-regulation periods, we calculated changes in sodium intake due to reformulation of food products, not behavior change. We statistically tested differences in mean consumption in this sample with paired t-tests.
Setting:
Langa, Western Cape, South Africa
Participants:
Surveyed participants were residents of Langa between 18-39 years old (n=2,148)
Results:
Before and after the implementation of the regulation there was a statistically significant decrease in the estimated sodium intake among adults of 189.4 mg (137.5, 241.4; p=0.00). Reported sodium from cured meat (such as Russians) and certain types of soup powder, cereals, and salted peanuts had a 9 to 33 percent lower calculated sodium consumption.
Conclusions:
Our conclusions show that independent of any behavioral changes on the part of consumers, it is possible to lower sodium intake by using regulations to induce food manufacturers to lower the sodium levels in their products. As countries explore similar regulatory strategies, this work can add to that body of evidence to inform policies to improve the food system.
Renal sinus fat (RSF) crucially influences metabolic regulation, inflammation, and vascular function. We investigated the association between RSF accumulation, metabolic disorders, and nutritional status in obese individuals with hypertension. A cross-sectional study involved 51 obese hypertensive patients from Salamat Specialized Community Clinic (February–September 2022). Basic and clinical information were collected through interviews. Data included anthropometrics, blood pressure, number of antihypertensive medications, body composition (bioelectrical impedance analysis), dietary intake (semi-quantitative 147-item food frequency questionnaire), and blood samples. Renal sinus fat was measured via ultrasonography. Statistical analyses included Pearson correlation, binary logistic regression, and linear regression. RSF positively correlated with abdominal visceral adipose tissue (VAT) area (P = 0.016), systolic blood pressure (SBP) (P = 0.004), and diastolic blood pressure (DBP) (P = 0.005). A strong trend toward a positive association was observed between antihypertensive medications and RSF (P = 0.062). In linear regression, RSF was independently associated with abdominal VAT area, SBP, and DBP after adjusting for confounders. After considering other risk factors, RSF volume relates to prescribed antihypertensive medications, hypertension, and central fat accumulation in obese hypertensive subjects. These findings suggest the need for further investigations into whether RSF promotes metabolic disorders.
The China Rural Hypertension Control Project (CRHCP) is a nonphysician-led community-based hypertension intervention program that has demonstrated clear benefits in improving blood pressure (BP) control and reducing the incidence of cardiovascular disease events among hypertensive patients in rural areas of China. However, it is currently unclear whether the benefits of the CRHCP outweigh its costs, and whether promoting this project in China is justifiable from a perspective of healthcare system.
Methods
We employed a Markov model to forecast the anticipated 20-year costs and effectiveness of the CRHCP trial. Cost data for this study was gathered from public records or published papers, whereas clinical data was extracted from the CRHCP trial. Our primary outcome measure was the incremental cost-effectiveness ratio, expressed in Chinese Yuan (CNY) per quality-adjusted life-year (QALY), representing the additional cost per additional QALY gained.
Results
Over a span of 20 years, the cost for a rural hypertensive individual in China who received intensive BP intervention by a nonphysician community healthcare provider would amount to 25,129 CNY, yielding an effectiveness of 8.19 QALY. In contrast, if usual care was provided, the cost would be 26,709 CNY with an effectiveness of 7.94 QALY. The CRHCP program demonstrated lower costs and greater effectiveness for rural hypertensive individuals in China.
Conclusion
Our study indicates that the implementation of the CRHCP program among rural hypertensive individuals in China resulted in increased effectiveness and reduced costs. From the perspective of Chinese healthcare system, the CRHCP program proves to be cost-saving within the current healthcare landscape.
Evaluation of benefits beyond quantitative academic outputs is essential in determining translational research value. We used the Translational Science Benefits Model (TSBM) to examine the impact of the QUARTET USA trial using 30 benefits across 4 domains: Clinical, Community, Economic, and Policy. We found that the QUARTET USA trial demonstrated impact in six areas within the Clinical, and Community domains and had potential impact in two additional areas within the Community and Economic domains. Use of the TSBM supports the value of the QUARTET USA trial, which can be used as a template for future cardiovascular trials.
Tuberculosis infection (TBI) has been associated with increased cardiovascular risks. We aimed to characterize abnormal blood pressure (BP) readings in individuals with TBI. We conducted a retrospective study of adults with TBI presenting for their initial medical visit at a large midwestern U.S. public health clinic between 2019 and 2020. Abnormal BP was defined as having a systolic BP ≥ 130 mmHg and/or a diastolic BP ≥ 80 mmHg. Of 310 individuals with TBI, median age was 36 years (interquartile range 27–48), 34% were male, 64% non-US-born; 58 (18.7%) were previously diagnosed with hypertension. The prevalence of any hypertension (i.e., had a history of hypertension and/or an abnormal BP reading) was 64.2% (95% confidence interval 58.7–69.4). Any hypertension was independently associated with older age, male sex, higher body mass index, and individuals of Black race. In conclusion, any hypertension was present in over half of the adults evaluated for TBI in our clinic. Established hypertension risk factors were also common among this group, suggesting that individuals with TBI could benefit from clinical and public health interventions aiming to reduce the risk of future cardiovascular events.
This study aimed to investigate the effects of pain management according to the World Health Organization (WHO) analgesic ladder on pain severity, pain interference, and blood pressure (BP) in treated hypertensive patients with chronic musculoskeletal pain.
Background:
Pain management can affect BP control owing to the proposed mechanism by which persistent pain contributes to increased BP. However, there are inadequate studies investigating the benefit of pain management in controlling both pain and BP in hypertensive patients who have chronic pain.
Methods:
In this cross-sectional study, demographic data and pain characteristics (resting pain score on the numerical pain rating scale, pain severity, and pain interference subscale of the Brief Pain Inventory) were collected via face-to-face interviews. BP was measured thrice on the same day. Data on pain medications taken in the previous 1 month were retrieved from the medical records. Participants were categorized into three groups following pain management patterns according to the WHO analgesic ladder: no, partial, and complete treatment. Multivariate logistic regression analysis (MLRA) was used to analyse the association between the variables and uncontrolled BP.
Findings:
Among 210 participants, the mean (standard deviation) age was 68 (15.5) years, and 60.47% had uncontrolled BP. The resting pain score, pain severity, and pain interference subscale scores of the complete treatment group were significantly lower than that of the partial treatment group (P = 0.036, 0.026, and 0.044, respectively). The MLRA revealed that pain management patterns were associated with uncontrolled BP (adjusted odds ratio [AOR]: 6.75; 95% confidence interval [CI]: 2.71−16.78; P < 0.001) and resting pain scores (AOR: 1.17; 95% CI: 1.04−1.38; P = 0.048). Our findings suggest that pain management patterns adhering to the WHO analgesic ladder can reduce pain severity and pain interference and also control BP in hypertensive patients with chronic musculoskeletal pain.
