Blood pressure(BP) management interventions have been shown to be more effective when accompanied by appropriate patient education. As high BP remains poorly controlled, there may be gaps in patient knowledge and education. Therefore, this study aimed to identify specific content and delivery preferences for information to support BP management among Australian adults from the general public. Given that BP management is predominantly undertaken by general practitioners(GPs), information preferences to support BP management were also ascertained from a small sample of Australian GPs. An online survey of adults was conducted to identify areas of concern for BP management to inform content preferences and preferred format for information delivery. A separate online survey was also delivered to GPs to determine preferred information sources to support BP management. Participants were recruited via social media. General public participants (n = 465) were mostly female (68%), >60 years (57%) and 49% were taking BP-lowering medications. The management of BP without medications, and role of lifestyle in BP management were of concern among 30% and 26% of adults respectively. Most adults (73%) preferred to access BP management information from their GP. 57% of GPs (total n = 23) preferred information for supporting BP management to be delivered via one-page summaries. This study identified that Australian adults would prefer more information about the management of BP without medications and via lifestyle delivered by their GP. This could be achieved by providing GPs with one-page summaries on relevant topics to support patient education and ultimately improve BP management., (© 2022. The Author(s).)

Objectives: In general, a terminology shared and agreed by different stakeholders is important to facilitate communication and cooperation. This holds true in the field of vascular ageing for the benefit of global cardiovascular health. The need to promote a common language and understanding across this area was recognised by VascAgeNet, a collaborative network with relevant and diverse expertise in the vascular ageing field, supported by the European Cooperation in Science and Technology. To contribute to the spread of unified terms in the vascular ageing field, a glossary was created by VascAgeNet and this paper describes the systematic process used for its development., Methods: An initial list of terms and preliminary definitions were collated from the network. A dedicated team was created to design the glossary development process, to facilitate its implementation and to maximise outreach and dissemination. The key steps of the process were to determine: (1) the target audience; (2) a list of priority terms; (3) a template structure for definitions; (4) methods for collecting feedback and (5) the dissemination plan., Results: An implementation strategy was provided for each key step and shared within the network; main decisions were agreed by all members of the glossary team. Small groups of definitions were released on a regular basis within a pilot phase including 19 terms (status: 05.09.2023) that were published openly at https://vascagenet.eu/official-glossary., Conclusions: The strategy for creating the first Vascular Ageing Glossary has been successfully designed and developed within VascAgeNet. A pilot phase covering the first publicly available terms was completed. The glossary is a living document, available to the scientific community, which aims to unify the vascular ageing language., Supplementary Information: The online version contains supplementary material available at 10.1007/s44200-023-00041-5., Competing Interests: Conflict of InterestElisabetta Bianchini is co-founder of QUIPU s.r.l., Pisa, Italy a spin-off company of the Italian National Research Council and the University of Pisa developing software medical devices.

Age is a key risk factor for cardiovascular disease, including atherosclerosis. However, pathophysiological disease processes in the arteries are not an inevitable feature of aging. Large cohort studies with arterial phenotyping along with clinical and demographic data are essential to better understand factors related to the susceptibility or resilience to age-related vascular pathophysiology in humans. This review explores the mechanisms by which vascular structure and function alters with age, and how these changes relate to cardiovascular pathophysiology and disease. Features of vascular aging in the coronary arteries have historically been difficult to quantify pre-mortem due to their size and location. However, non-invasive imaging modalities including CT Coronary Angiogram are now being used to assess coronary vascular age, and further advances in imaging analysis such as the CT Fat Attenuation Index will help provide further measurement of features associated with coronary vascular aging. Currently, markers of vascular aging are not used as therapeutic targets in routine clinical practice, but non-pharmacological interventions including aerobic exercise and low salt diet, as well as anti-hypertensives have been demonstrated to reduce arterial stiffness. Advances in imaging technology, both in acquisition and advanced analysis, as well as harmonisation of measurements for researchers across the globe will be invaluable in understanding what constitutes healthy vascular aging and in identifying features of vascular aging that are associated with coronary artery disease and its adverse outcomes. Assessing such images in large cohorts can facilitate improved definitions of resilient and susceptible phenotypes to vascular aging in the coronary arteries. This is a critical step in identifying further risk factors and biomarkers within these groups and driving forward the development of novel therapies aimed at slowing or stopping age-related vascular changes in the coronary arteries., Competing Interests: GF reports personal consulting fees from CSL, Novartis and grants from Abbott Diagnostic outside the submitted work.

Non-invasive ultrasound (US) imaging enables the assessment of the properties of superficial blood vessels. Various modes can be used for vascular characteristics analysis, ranging from radiofrequency (RF) data, Doppler- and standard B/M-mode imaging, to more recent ultra-high frequency and ultrafast techniques. The aim of the present work was to provide an overview of the current state-of-the-art non-invasive US technologies and corresponding vascular ageing characteristics from a technological perspective. Following an introduction about the basic concepts of the US technique, the characteristics considered in this review are clustered into: 1) vessel wall structure; 2) dynamic elastic properties, and 3) reactive vessel properties. The overview shows that ultrasound is a versatile, non-invasive, and safe imaging technique that can be adopted for obtaining information about function, structure, and reactivity in superficial arteries. The most suitable setting for a specific application must be selected according to spatial and temporal resolution requirements. The usefulness of standardization in the validation process and performance metric adoption emerges. Computer-based techniques should always be preferred to manual measures, as long as the algorithms and learning procedures are transparent and well described, and the performance leads to better results. Identification of a minimal clinically important difference is a crucial point for drawing conclusions regarding robustness of the techniques and for the translation into practice of any biomarker., (© 2023 The Authors.

This review critiques the literature supporting clinical assessment and management of cardiovascular disease and cardiovascular disease risk stratification with brachial-ankle pulse wave velocity (baPWV). First, we outline what baPWV actually measures-arterial stiffness of both large central elastic arteries and medium-sized muscular peripheral arteries of the lower limb. Second, we argue that baPWV is not a surrogate for carotid-femoral pulse wave velocity. While both measures are dependent on the properties of the aorta, baPWV is also strongly dependent on the muscular arteries of the lower extremities. Increased lower-extremity arterial stiffness amplifies and hastens wave reflections at the level of the aorta, widens pulse pressure, increases afterload, and reduces coronary perfusion. Third, we used an established evaluation framework to identify the value of baPWV as an independent vascular biomarker. There is sufficient evidence to support (1) proof of concept; (2) prospective validation; (3) incremental value; and (4) clinical utility. However, there is limited or no evidence to support (5) clinical outcomes; (6) cost-effectiveness; (8) methodological consensus; or (9) reference values. Fourth, we address future research requirements. The majority of the evaluation criteria, (1) proof of concept, (2) prospective validation, (3) incremental value, (4) clinical utility and (9) reference values, can be supported using existing cohort datasets, whereas the (5) clinical outcomes and (6) cost-effectiveness criteria require prospective investigation. The (8) methodological consensus criteria will require an expert consensus statement. Finally, we finish this review by providing an example of a future clinical practice model., Competing Interests: Disclosures None.

Background: Survivors of allogeneic stem cell transplant (SCT) receive intensive cancer treatments that are associated with cardiovascular dysfunction. Markers of vascular age can indicate early signs of adverse (cardio)vascular changes; however, the impact of SCT on these makers is unknown. We aimed to determine the short (3 months) and longer-term (≥2 years) effect of SCT on markers of vascular age in hematologic cancer survivors compared with an age-matched noncancer control group., Methods: The short-term effects of SCT, markers of vascular age (aortic compliance, arterial elastance, and ventricular-vascular coupling) were assessed via cardiac magnetic resonance imaging (cardiac and aortic volumes) before and ≈3 months post-SCT in 13 short-term survivors and compared with 11 controls. The longer-term impact was assessed by comparing 14 long-term survivors (6.5 [2-20] years post-SCT) to the short-term survivors (post-SCT) and controls (n=16)., Results: The groups were similar for age and body mass index. In the short-term survivors, no significant group-by-time interactions were observed for any markers of vascular aging from pretransplant to posttransplant (net difference for change in compliance between groups -0.07 [95% CI, -1.49 to 1.35]). For the time-course analysis, aortic compliance was significantly lower in both SCT groups (overall P =0.007) compared with controls, whereas ventricular-vascular coupling was higher in both survivor groups as was arterial elastance in long-term SCT survivors (ie, worse; P <0.01 for all)., Conclusion: This study provides evidence of an accelerated vascular aging phenotype in allogeneic SCT survivors and provides insight into the increased burden of cardiovascular disease among hematologic cancer survivors., Competing Interests: Disclosures None.

Prevention of cardiovascular disease (CVD) remains one of the largest public health challenges of our time. Identifying individuals at increased cardiovascular risk at an asymptomatic, sub-clinical stage is of paramount importance for minimizing disease progression as well as the substantial health and economic burden associated with overt CVD. Vascular ageing (VA) involves the deterioration in vascular structure and function over time and ultimately leads to damage in the heart, brain, kidney, and other organs. Vascular ageing encompasses the cumulative effect of all cardiovascular risk factors on the arterial wall over the life course and thus may help identify those at elevated cardiovascular risk, early in disease development. Although the concept of VA is gaining interest clinically, it is seldom measured in routine clinical practice due to lack of consensus on how to characterize VA as physiological vs. pathological and various practical issues. In this state-of-the-art review and as a network of scientists, clinicians, engineers, and industry partners with expertise in VA, we address six questions related to VA in an attempt to increase knowledge among the broader medical community and move the routine measurement of VA a little closer from bench towards bedside., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

Importance: Cardiovascular health may be used for prevention of depressive symptoms. However, data on the association of cardiovascular health across midlife with depressive symptoms are lacking., Objective: To evaluate whether better baseline cardiovascular health and improvement of cardiovascular health over time are associated with a lower risk of both incident depressive symptoms and unfavorable trajectories of depressive symptoms., Design, Setting, and Participants: Participants without depressive symptoms were included from a prospective community-based cohort in France (GAZEL cohort). Cardiovascular health examinations occurred in 1990 and 1997 and assessment of depressive symptoms in 1997 and every 3 years thereafter until 2015. Data were analyzed from January to October 2022., Exposures: Number of cardiovascular health metrics (smoking, body mass index, physical activity, diet, blood pressure, glucose, and cholesterol) at an intermediate or ideal level in 1997 (range, 0-7) and 7-year change in cardiovascular health between 1990 and 1997., Main Outcomes and Measures: Primary outcome was incident depressive symptoms (20-item Center for Epidemiologic Studies-Depression Scale [CES-D] score of 17 or greater in men or 23 or greater in women); secondary outcome was trajectories of depressive symptoms scores. Trajectories included consistently low scores, moderately elevated scores, low starting then increasing scores, moderately high starting, increasing, then remitting scores, and moderately high starting then increasing scores., Results: Of 6980 included patients, 1671 (23.9%) were women, and the mean (SD) age was 53.3 (3.5) years. During a follow-up spanning 19 years after 1997, 1858 individuals (26.5%) had incident depressive symptoms. Higher baseline cardiovascular health in 1997 and improvement in cardiovascular health over 7 years were each associated with lower risk of depressive symptoms (odds ratio [OR] per additional metric at intermediate or ideal level at baseline, 0.87; 95% CI, 0.84-0.91; OR per 1 higher metric at intermediate or ideal level over 7 years, 0.91; 95% CI, 0.86-0.96). Also, better cardiovascular health was associated with lower risk of unfavorable depressive symptoms trajectories. Compared with the consistently low score trajectory, the lowest risks were observed for the low starting then increasing score trajectory (OR per additional metric at intermediate or ideal level at baseline, 0.70; 95% CI, 0.64-0.76; OR per 1 higher metric at intermediate or ideal level over 7 years, 0.73; 95% CI, 0.68-0.79) and the moderately high starting then increasing score trajectory (OR per additional metric at intermediate or ideal level at baseline, 0.71; 95% CI, 0.64-0.79; OR per 1 higher metric at intermediate or ideal level over 7 years, 0.71; 95% CI, 0.64-0.77)., Conclusions and Relevance: In this prospective community-based cohort study of adults, higher cardiovascular health was associated with a lower risk of depressive symptoms over time. Elucidating which set of cardiovascular factors may affect depression risk could be important for prevention.

Background: The commonality of risk factors between cancer and cardiovascular disease suggests that primordial prevention (preventing the onset of risk factors) is a relevant strategy for cancer prevention., Objectives: This study sought to examine the association between baseline and change in the cardiovascular health (CVH) score and incident cancer., Methods: Using serial examinations of the GAZEL (GAZ et ELECTRICITE de France) study in France, we examined the associations between the American Heart Association's Life's Simple 7 CVH score (range: 0-to 14 [poor, intermediate, and ideal level of smoking, physical activity, body mass index, diet, blood pressure, diabetes status, or lipids]) in 1989/1990, their change over 7 years, and incident cancer and cardiac events up to 2015., Results: The study population included 13,933 participants (mean age: 45.3 ± 3.4 years, 24% women). After a median follow-up of 24.8 years (Q1-Q3: 19.4-24.9 years), 2,010 participants had an incident cancer and 899 a cardiac event. The risk of cancer (any site) decreased by 9% (HR: 0.91; 95% CI: 0.88-0.93) per 1-point increase in the CVH score in 1989/1990 compared with a 20% (HR: 0.80; 95% CI: 0.77-0.83) risk reduction for cardiac events. The risk of cancer decreased by 5% (HR: 0.95; 95% CI: 0.92-0.99) per unit of change in the CVH score between 1989/1990 and 1996/1997 compared with a 7% risk reduction for cardiac events (HR: 0.93; 95% CI: 0.88-0.98). These associations remained after omitting the smoking metric from the CVH score., Conclusions: Primordial prevention is a relevant strategy for the prevention of cancer in the population., Competing Interests: The GAZEL cohort study was funded by Electricité de France-Gaz de France and Institut National de la Santé et de la Recherche Médicale and received grants from the Cohortes Santé TGIR Program, Agence Nationale de la Recherché (grant ANR-08-BLAN-0028), Agence Française de Sécurité Sanitaire de l’Environnement et du Travail (grant EST-2008/1/35), Caisse d’Assurance Maladie des Industries Électrique et Gazière), and Caisse Centrale d’Activités Sociales du Personnel des Industries Électriques et Gazières.

Background: Vascular age (VA) is independent and chronological age for assessing cardiovascular disease (CVD) risk. However, tools for the implementation of VA are currently lacking. We aimed to develop a questionnaire to assess the current knowledge gaps related to VA and barriers to its implementation in routine practice., Methods: Using a stepwise mixed-method approach, a quantitative questionnaire was constructed in four phases: (1) basic item generation and the development of a semi-qualitative questionnaire (SQQ); (2) dissemination to the VascAgeNet extended network and an analysis of the semi-qualitative questionnaire responses; (3) the development of a quantitative questionnaire (QQ); and (4) an assessment of the content and face validity and internal reliability in an additional sample., Results: Based on six main topics initially identified through an expert panel, a SQQ was developed and disseminated. Finally, a 22-item QQ was developed, with questions grouped around three main themes: knowledge of VA and its risk factors; perceptions and beliefs regarding the importance and contribution of VA to risk classification; and the application of VA measurements in clinical and research practice and its potential limitations (Cronbach's alpha between 0.920 and 0.982 for all three categories)., Conclusion: We report the development of a QQ on VA addressed to both clinicians and non-clinicians aiming to assess their knowledge, perceptions and application of VA measurements.

Fibers remain undigested until they reach the colon, where some are fermented by gut microbiota, producing metabolites called short-chain fatty acids (SCFAs), such as acetate and butyrate 1 . SCFAs lower blood pressure in experimental models 2-5 , but their translational potential is unknown. Here we present the results of a phase II, randomized, placebo-controlled, double-blind cross-over trial (Australian New Zealand Clinical Trials Registry ACTRN12619000916145) using prebiotic acetylated and butyrylated high-amylose maize starch (HAMSAB) supplementation 6 . Twenty treatment-naive participants with hypertension were randomized to 40 g per day of HAMSAB or placebo, completing each arm for 3 weeks, with a 3-week washout period between them. The primary endpoint was a reduction in ambulatory systolic blood pressure. Secondary endpoints included changes to circulating cytokines, immune markers and gut microbiome modulation. Patients receiving the HAMSAB treatment showed a clinically relevant reduction in 24-hour systolic blood pressure independent of age, sex and body mass index without any adverse effects. HAMSAB increased levels of acetate and butyrate, shifted the microbial ecosystem and expanded the prevalence of SCFA producers. In summary, a prebiotic intervention with HAMSAB could represent a promising option to deliver SCFAs and lower blood pressure in patients with essential hypertension., (© 2023.

Cardiovascular disease (CVD) has long been deemed a disease of old men. However, in 2019 CVD accounted for 35% of all deaths in women and, therefore, remains the leading cause of death in both men and women. There is increasing evidence to show that risk factors, pathophysiology and health outcomes related to CVD differ in women compared with men, yet CVD in women remains understudied, underdiagnosed and undertreated. Differences exist between the sexes in relation to the structure of the heart and vasculature, which translate into differences in blood pressure and flow waveform physiology. These physiological differences between women and men may represent an important explanatory factor contributing to the sex disparity in CVD presentation and outcomes but remain understudied. In this review we aim to describe sex differences in arterial pressure and flow waveform physiology and explore how they may contribute to differences in CVD in women compared to men. Given that unfavourable alterations in the cardiovascular structure and function can start as early as in utero, we report sex differences in waveform physiology across the entire life course., (Copyright © 2022 Wolters Kluwer Health, Inc.

Cardiovascular disease remains the leading cause of death worldwide. Cardiovascular research has therefore never been more crucial. Cardiovascular researchers must be provided with a research environment that enables them to perform at their highest level, maximizing their opportunities to work effectively with key stakeholders to address this global issue. At present, cardiovascular researchers face a range of challenges and barriers, including a decline in funding, job insecurity and a lack of diversity at senior leadership levels. Indeed, many cardiovascular researchers, particularly women, have considered leaving the sector, highlighting a crucial need to develop strategies to support and retain researchers working in the cardiovascular field. In this Roadmap article, we present solutions to problems relevant to cardiovascular researchers worldwide that are broadly classified across three key areas: capacity building, research funding and fostering diversity and equity. This Roadmap provides opportunities for research institutions, as well as governments and funding bodies, to implement changes from policy to practice, to address the most important factors restricting the career progression of cardiovascular researchers., (© 2022.

Background: Achieving healthy vascular aging (HVA) is important for decelerating age-related cardiovascular disease risk. We evaluated the interplay between HVA, cardiorespiratory fitness (CRF), and subclinical atherosclerosis., Methods: We analyzed data on 3722 men who underwent cardiopulmonary exercise testing in a health examination program. HVA was defined as blood pressure <140/90 mm Hg without hypertension and brachial-ankle pulse wave velocity <1266 cm/s. CRF was directly measured by peak oxygen uptake. Subclinical atherosclerosis was defined as coronary artery calcification scores of >0 and ≥100 and a mean carotid artery intima-media thickness (CIMT) >75th percentile for each age group as well as >0.8 mm of CIMT. Separate and joint associations of HVA and CRF with subclinical atherosclerosis were evaluated., Results: Each 1 metabolic equivalent increment in CRF was associated with 23% higher odds for having HVA. HVA was associated with lower odds of coronary artery calcification but not CIMT. CRF modified the association between HVA and CIMT>0.8 mm (interaction: P =0.01); HVA was associated with lower odds of CIMT>0.8 mm in fit men with no significant association between HVA and CIMT>0.8 mm in unfit men. Compared with no HVA and being unfit, HVA and being fit was associated with lower odds of subclinical atherosclerosis, but there was no significant association between HVA and being unfit with subclinical atherosclerosis., Conclusions: HVA and higher CRF are each associated with a lower risk of subclinical atherosclerosis in men. Higher CRF is associated with a higher prevalence of HVA and may modify the association between HVA and subclinical atherosclerosis.

Background: Early childhood may represent an opportune time to commence primordial prevention of cardiovascular disease (CVD, i.e., prevention of risk factors onset), but epidemiological evidence is scarce. We aimed to examine the distribution and parental and early life determinants of ideal cardiovascular health (CVH) in children up to 5 years and to compare the level of cognitive development between children with and without ideal CVH at age 5 years., Methods: Using data from the Etude sur les déterminants pré et post natals précoces du Développement psychomoteur et de la santé de l'Enfant (EDEN) study, a French population-based mother-child cohort study, CVH was examined in children at 5 years of age based on the American Heart Association CVH metrics (ideal body mass index, physical activity, diet, blood pressure, cholesterol and glucose levels, and passive smoking, considered in sensitivity analysis only). Children were categorized as having ideal (five to six ideal metrics) or non-ideal CVH (<5 ideal metrics). Intelligence quotient (IQ) at age 5 years was assessed using the French version of the Wechsler Preschool and Primary Scale of Intelligence., Results: Among the 566 children (55% boys), only 34% had ideal CVH. In fully adjusted logistic regression, boys compared to girls (OR = 1.77, 95% CI 1.13-2.78), children with intermediate (1.77, 1.05-2.98) or ideal (2.58, 1.38-4.82) behavioral CVH at age 3 years and children who spent < 30 min/day watching television (1.91, 1.09-3.34) at age 3 years were more likely to have ideal CVH at age 5 years. At age 5 years, there was a significant 2.98-point difference (95% CI 0.64-5.32) in IQ between children with and without ideal biological CVH after adjusting for confounders., Conclusion: This study highlights that only a third of children aged 5 years had ideal CVH and identified modifiable determinants of ideal CVH and is suggestive of an association between CVH and neurodevelopment at a young age., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Climie, Tafflet, Sloten, Lauzon-Guillain, Bernard, Dargent-Molina, Plancoulaine, Lioret, Jouven, Charles, Heude and Empana.)

High blood pressure (BP) is a leading risk factor for cardiovascular disease (CVD). The identification of high BP is conventionally based on in-clinic (resting) BP measures, performed within primary health care settings. However, many cases of high BP go unrecognised or remain inadequately controlled. Thus, there is a need for complementary settings and methods for BP assessment to identify and control high BP more effectively. Exaggerated exercise BP is associated with increased CVD risk and may be a medium to improve identification and control of high BP because it is suggestive of high BP gone undetected on the basis of standard in-clinic BP measures at rest. This paper provides the evidence to support a pathway to aid identification and control of high BP in clinical exercise settings via the measurement of exercise BP. It is recommended that exercise professionals conducting exercise testing should measure BP at a fixed submaximal exercise workload at moderate intensity (e.g., ~70% age-predicted heart rate maximum, stage 1-2 of a standard Bruce treadmill protocol). If exercise systolic BP is raised (≥170 mmHg), uncontrolled high BP should be assumed and should trigger correspondence with a primary care physician to encourage follow-up care to ascertain true BP control (i.e., home, or ambulatory BP) alongside a hypertension-guided exercise and lifestyle intervention to lower CVD risk related to high BP.

Background: Diabetes is associated with increased hospital complications and mortality following trauma. However, there is limited research on the longer-term recovery of trauma patients with diabetes. The aim of this study was to explore the association between type 2 diabetes (T2D) and in-hospital and 24-month outcomes in major trauma patients., Methods: In this cohort study using the Victorian State Trauma Registry, middle-aged and older adults (≥45 years) with major trauma were followed up at 24 months postinjury. Logistic regression (univariable and multivariable) analyses were used to determine the association between diabetes status and 24-month patient-reported outcomes. In-hospital outcomes were compared between groups using χ2 tests., Results: Of the 11,490 participants who survived to hospital discharge, 8,493 survived to 24 months postinjury and were followed up at that time point: 953 people (11%) with and 7540 (89%) without T2D. People with T2D had a higher in-hospital death rate (19%) compared with people without T2D (16%; p < 0.001). After adjusting for confounders, people with T2D had poorer outcomes 24 months postinjury than people without T2D, with respect to functional recovery (Glasgow Outcome Scale Extended) (adjusted odds ratio [AOR], 0.58; 95% confidence interval [CI], 0.48-0.69) and return to work/study (AOR, 0.51; 95% CI, 0.37-0.71]). People with T2D experienced higher odds of problems with mobility (AOR, 1.92; 95% CI, 1.60-2.30), self-care (AOR, 1.94; 95% CI, 1.64, 2.29), usual activities (AOR, 1.50; 95% CI, 1.26-1.79), pain and discomfort (AOR, 1.75; 95% CI, 1.49-2.07), anxiety and depression (AOR, 1.45; 95% CI, 1.24, 1.70), and self-reported disability (AOR, 1.51; 95% CI, 1.28-1.79) than people without T2D., Conclusion: Major trauma patients with T2D have a poorer prognosis than patients without T2D, both during their hospital admission and 24 months postinjury. Patients with T2D may need additional health care and support following trauma to reach their recovery potential., Level of Evidence: Prognostic, level III., (Copyright © 2021 Wolters Kluwer Health, Inc.

Vascular ageing biomarkers have been found to be predictive of cardiovascular risk independently of classical risk factors, yet are not widely used in clinical practice. In this review, we present two basic approaches for using machine learning (ML) to assess vascular age: parameter estimation and risk classification. We then summarize their role in developing new techniques to assess vascular ageing quickly and accurately. We discuss the methods used to validate ML-based markers, the evidence for their clinical utility, and key directions for future research. The review is complemented by case studies of the use of ML in vascular age assessment which can be replicated using freely available data and code., Competing Interests: Conflict of interest: none declared.

Impairment of the arteries is a product of sustained exposure to various deleterious factors and progresses with time; a phenomenon inherent to vascular aging. Oxidative stress, inflammation, the accumulation of harmful agents in high cardiovascular risk conditions, changes to the extracellular matrix, and/or alterations of the epigenetic modification of molecules, are all vital pathophysiological processes proven to contribute to vascular aging, and also lead to changes in levels of associated circulating molecules. Many of these molecules are consequently recognized as markers of vascular impairment and accelerated vascular aging in clinical and research settings, however, for these molecules to be classified as biomarkers of vascular aging, further criteria must be met. In this paper, we conducted a scoping literature review identifying thirty of the most important, and eight less important, biomarkers of vascular aging. Herein, we overview a selection of the most important molecules connected with the above-mentioned pathological conditions and study their usefulness as circulating biomarkers of vascular aging., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Gopcevic, Gkaliagkousi, Nemcsik, Acet, Bernal-Lopez, Bruno, Climie, Fountoulakis, Fraenkel, Lazaridis, Navickas, Rochfort, Šatrauskienė, Zupkauskienė and Terentes-Printzios.)

Background: A hypertensive response to exercise (HRE) is associated with cardiovascular disease and high blood pressure (BP). A poor cardiovascular risk factor profile may underlie these associations, although this has not been systematically elucidated. Via systematic review and meta-analysis, we aimed to assess the relationship between exercise BP and cardiovascular risk factors, and determine if cardiovascular risk is higher in those with an HRE vs. no-HRE across different study populations (including those with/without high BP at rest)., Methods: Three online databases were searched for cross-sectional studies reporting data on exercise BP, an HRE and cardiovascular risk factors (including arterial structure, lipid, metabolic, inflammatory and kidney function markers). Random-effects meta-analyses and meta-regression were used to calculate pooled correlations between exercise BP and each risk factor and pooled mean differences between those with/without an HRE., Results: Thirty-eight studies (38 295 participants, aged 50 ± 3years; 78% male) were included. Exercise SBP was associated with arterial, lipid and kidney function risk markers (P < 0.05). Those with an HRE had greater aortic stiffness (+0.80 ± 0.35 m/s), total (+0.14 ± 0.03 mmol/l) and low-density lipoprotein (+0.12 ± 0.03 mmol/l) cholesterol, triglycerides (+0.24 ± 0.04 mmol/l), glucose (+0.15 ± 0.05 mmol/l), white blood cell count (+0.49 ± 0.16 mmol/l) and albumin-to-creatinine ratio (standardized mean difference: +0.97 ± 0.34), and lower flow-mediated dilation (-4.13 ± 1.02%) and high-density lipoprotein cholesterol (-0.04 ± 0.01 mmol/l) vs. those with no-HRE (P < 0.05 all). Results were broadly similar across study populations., Conclusion: Exercise SBP is associated with multiple cardiovascular risk factors, which appear worse in those with an HRE vs. no-HRE. As results were similar across population groups, an HRE should be considered an important indicator of cardiovascular risk., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Background: In the last two decades, the global prevalence of paediatric hypertension increased by approximately 75%. Nearly 25% of children are now classified as obese or overweight. Substantial evidence suggests that risk factors for cardiovascular disease (CVD) begin to develop in childhood, thus warranting the need for tools to better screen for early CVD risk in youth. Vascular ageing, the deterioration of vascular structure and function, may be a potentially useful tool for detecting the early and asymptomatic signs of CVD burden. However, it is currently unclear what differentiates normal from pathological ageing in youth as existing reference values for vascular ageing in youth are limited by small sample size or homogenous populations. The international Youth Vascular Consortium (YVC) has been established to address these issues., Aims: The primary aim of the YVC is to develop reference intervals of normal vascular ageing in children, adolescents, and young adults. The secondary, exploratory, aim is to perform head-to-head comparisons of vascular ageing biomarkers to determine which biomarker is most strongly related to cardiometabolic health., Study Design: The YVC is a retrospective, multicentre study and will collate data on vascular ageing in children (5-12 years), adolescents (13-18 years) and young adults (19-40 years), as well as routine clinical biochemistry, lifestyle, sociodemographic factors and parental health., Conclusion: To date, 31 research groups from 19 countries have joined the YVC. To our knowledge, this will be the largest study of its kind to investigate vascular ageing in youth., (Copyright © 2021 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Extensive evidence shows that risk factors for cardiovascular disease (CVD) begin to develop early in life. Childhood obesity and elevated blood pressure (BP) have become overwhelmingly challenging, with 57% of today's children predicted to be obese by the age of 35 years, and global rates of hypertension in children and adolescents increasing by 75% from 2000 to 2015. Thus, there is an urgent need for tools that can assess early CVD risk in youth, which may lead to better risk stratification, preventative intervention, and personalised medicine. Vascular ageing (the deterioration in vascular structure and function) is a pivotal progenitor of health degeneration associated with elevated BP. Exposure to adverse environmental and genetic factors from fetal life promotes the development and accumulation of subclinical vascular changes that direct an individual towards a trajectory of early vascular ageing (EVA)-an independent predictor of target organ damage in the heart, brain, and kidneys. Therefore, characterising vascular ageing from youth may provide a window into cardiovascular risk later in life. However, vascular ageing measurements only have value when techniques are accurate/validated and when reliable thresholds are available for defining normal ranges and ranges that signal increased risk of disease. The aim of this paper is to summarise current evidence on the importance of vascular ageing assessment in youth and the impact of interventions to prevent or delay EVA, to highlight the need for standardisation and validation of measurement techniques in children and adolescents, and the importance of establishing reference values for vascular ageing measures in this population., (Copyright © 2021 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Objectives: A hypertensive response to exercise (HRE) is associated with cardiovascular disease and high blood pressure (BP). Sub-clinical changes to cardiac structure may underlie these associations, although this has not been systematically determined. Via systematic review and meta-analysis, we aimed to (1) assess the relationship between exercise BP and cardiac structure, and (2) determine if cardiac structure is altered in those with an HRE, across various study populations (including those with/without high BP at rest)., Design and Methods: Three online databases were searched for cross-sectional studies reporting exercise BP, HRE and cardiac structural variables. Random-effects meta-analyses and meta-regressions were used to calculate pooled correlations between exercise BP and cardiac structure, and pooled mean differences and relative risk between those with/without an HRE., Results: Forty-nine studies, (n=23,707 total; aged 44±4 years; 63% male) were included. Exercise systolic BP was associated with increased left ventricular (LV) mass, LV mass index, relative wall thickness, posterior wall thickness and interventricular septal thickness (p<0.05 all). Those with an HRE had higher risk of LV hypertrophy (relative risk: 2.6 [1.85-3.70]), increased LV mass (47±7g), LV mass index (7±2g/m 2 ), relative wall thickness (0.02±0.005), posterior wall thickness (0.78±0.20mm), interventricular septal thickness (0.78±0.17mm) and left atrial diameter (2±0.52mm) vs. those without an HRE (p<0.05 all). Results were broadly similar between studies with different population characteristics., Conclusions: Exercise systolic BP is associated with cardiac structure, and those with an HRE show evidence towards adverse remodelling. Results were similar across different study populations, highlighting the hypertension-related cardiovascular risk associated with an HRE., (Copyright © 2021 Sports Medicine Australia.

Background: Hypertension is a prevalent chronic disease worldwide that remains poorly controlled. Recent studies support the concept that the gut microbiota is involved in the development of hypertension and that dietary fibre intake may act through the gut microbiota to lower blood pressure (BP). Resistant starch is a type of prebiotic fibre which is metabolised by commensal bacteria in the colon to produce short-chain fatty acids (SCFAs), including acetate, propionate, and butyrate. Previous work in pre-clinical models provides strong evidence that both prebiotic fibre as well as SCFAs (i.e. postbiotics) can prevent the development of hypertension. The aim of this clinical trial is to determine if acetylated and butyrylated modified resistant starch can decrease BP of hypertensive individuals via the modulation of the gut microbiota and release of high levels of SCFAs., Methods: This is a phase IIa double-blinded, randomised, cross-over, placebo controlled trial. Participants are randomly allocated to receive either a diet containing 40 g/day of the modified resistant starch or placebo (corn starch or regular flour) for 3 weeks on each diet, with a 3-week washout period between the two diets. BP is measured in the office, at home, and using a 24-h ambulatory device. Arterial stiffness is measured using carotid-to-femoral pulse wave velocity. Our primary endpoint is a reduction in ambulatory daytime systolic BP. Secondary endpoints include changes to circulating cytokines, immune markers, and modulation to the gut microbiome., Discussion: The findings of this study will provide the first evidence for the use of a combination of pre- and postbiotics to lower BP in humans.

Context/purpose: Observational and acute laboratory intervention research has shown that excessive sedentary time is associated adversely with cardiometabolic biomarkers. This systematic review with meta-analyses synthesises results from free living interventions targeting reductions in sedentary behaviour alone or combined with increases in physical activity., Methods: Six electronic databases were searched up to August 2019 for sedentary behaviour interventions in adults lasting for ≥7 days publishing cardiometabolic biomarker outcomes covering body anthropometry, blood pressure, glucose and lipid metabolism, and inflammation (54 studies). The pooled effectiveness of intervention net of control on 15 biomarker outcomes was evaluated using random effects meta-analyses in the studies with control groups not providing other relevant interventions (33 studies; 6-25 interventions analysed)., Results: Interventions between 2 weeks and <6 months in non-clinical populations from North America, Europe and Australia comprised much of the evidence base. Pooled effects revealed small, significant (p<0.05) beneficial effects on weight (≈ -0.6 kg), waist circumference (≈ -0.7 cm), percentage body fat (≈ -0.3 %), systolic blood pressure (≈ -1.1 mm Hg), insulin (≈ -1.4 pM) and high-density lipoprotein cholesterol (≈ 0.04 mM). Pooled effects on the other biomarkers (p>0.05) were also small, and beneficial in direction except for fat-free mass (≈ 0.0 kg). Heterogeneity ranged widely (I 2 =0.0-72.9)., Conclusions: Our review of interventions targeting sedentary behaviour reductions alone, or combined with increases in physical activity, found evidence of effectiveness for improving some cardiometabolic risk biomarkers to a small degree. There was insufficient evidence to evaluate inflammation or vascular function. Key limitations to the underlying evidence base include a paucity of high-quality studies, interventions lasting for ≥12 months, sensitive biomarkers and clinical study populations (eg, type 2 diabetes)., Prospero Trial Registration Number: CRD42016041742., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

In healthy and overweight/obese adults, interrupting prolonged sitting with activity bouts mitigates impairment in vascular function. However, it is unknown whether these benefits extend to those with type 2 diabetes (T2D), nor whether an optimal frequency of activity interruptions exist. We examined the acute effects on vascular function in T2D of interrupting prolonged sitting with simple resistance activities (SRA) at different frequencies. In a randomized crossover trial, 24 adults with T2D (35-70 yr) completed three 7-h conditions: 1 ) uninterrupted sitting (SIT), 2 ) sitting with 3-min bouts of SRA every 30 min (SRA3), and 3 ) sitting with 6 min bouts of SRA every 60 min (SRA6). Femoral artery flow-mediated dilation (FMD), resting shear rate, blood flow, and endothelin-1 were measured at 0, 1, 3.5, 4.5, and 6.5-7 h. Mean femoral artery FMD over 7 h was significantly higher in SRA3 (4.1 ± 0.3%) compared with SIT (3.7 ± 0.3%, P = 0.04) but not in SRA6. Mean resting femoral shear rate over 7 h was increased significantly for SRA3 (45.3 ± 4.1/s, P < 0.001) and SRA6 (46.2 ± 4.1/s, P < 0.001) relative to SIT (33.1 ± 4.1/s). Endothelin-1 concentrations were not statistically different between conditions. Interrupting sitting with activity breaks every 30 min, but not 60 min, significantly increased mean femoral artery FMD over 7 h, relative to SIT. Our findings suggest that more frequent and shorter breaks may be more beneficial than longer, less frequent breaks for vascular health in those with T2D. NEW & NOTEWORTHY This is the first trial to examine both the effects of interrupting prolonged sitting on vascular function in type 2 diabetes and the effects of the frequency and duration of interruptions. Brief, simple resistance activity bouts every 30 min, but not every 60 min, increased mean femoral artery flow-mediated dilation over 7 h, relative to uninterrupted sitting. With further supporting evidence, these initial findings can have important implications for cardiovascular health in type 2 diabetes.

Background: Cardiovascular disease is the leading cause of death in Australia. Investment in research solutions has been demonstrated to yield health and a 9.8-fold return economic benefit. The sector, however, is severely challenged with success rates of traditional peer-reviewed funding in decline. Here, we aimed to understand the perceived challenges faced by the cardiovascular workforce in Australia prior to the COVID-19 pandemic., Methods: We used an online survey distributed across Australian cardiovascular societies/councils, universities and research institutes over a period of 6 months during 2019, with 548 completed responses. Inclusion criteria included being an Australian resident or an Australian citizen who lived overseas, and a current or past student or employee in the field of cardiovascular research., Results: The mean age of respondents was 42±13 years, 47% were male, 85% had a full-time position, and 40% were a group leader or laboratory head. Twenty-three per cent (23%) had permanent employment, and 82% of full-time workers regularly worked >40 hours/week. Sixty-eight per cent (68%) said they had previously considered leaving the cardiovascular research sector. If their position could not be funded in the next few years, a staggering 91% of respondents would leave the sector. Compared to PhD- and age-matched men, women were less likely to be a laboratory head and to feel they had a long-term career path as a cardiovascular researcher, while more women were unsure about future employment and had considered leaving the sector (all p<0.05). Greater job security (76%) and government and philanthropic investment in cardiovascular research (72%) were highlighted by responders as the main changes to current practices that would encourage them to stay., Conclusion: Strategic solutions, such as diversification of career pathways and funding sources, and moving from a competitive to a collaborative culture, need to be a priority to decrease reliance on government funding and allow cardiovascular researchers to thrive., (Copyright © 2020 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Objectives: Hearing impairment (HI) is a leading impairment worldwide, and identifying modifiable risk factors of HI may have major public health implications. The aim of this study was to investigate the association between obstructive sleep apnoea (OSA) and HI., Design: Observational longitudinal study (the Paris Prospective Study 3)., Setting: Population-based., Participants: Volunteers aged 50-75 years and consulting at a preventive medical centre were included between 2008 and 2012. 6797 participants were included in the present analysis., Main Outcome Measures: Audiometry testing was performed in both ears in all participants, and HI was defined by a pure-tone average (PTA) >25 decibels (dB) hearing level in the better ear., Results: Obstructive sleep apnoea (estimated by the Berlin questionnaire) was present in 18.6% (n = 1267) and HI in 13.9% (n = 947) of the participants. Mean age was 59.5 years (SD 6.2) and 63.5% were male (n = 4317). In multiple logistic regression modelling, OSA was significantly associated with a 1.21-increased odds of HI (95% confidence interval 1.01-1.44). Several sensitivity analyses supported this finding., Conclusion: Obstructive sleep apnoea is associated with a 21% increased odds of HI. These results support active screening of HI in subjects with OSA, and future studies should evaluate whether the treatment of OSA can delay the onset of HI., (© 2020 John Wiley & Sons Ltd.)

Orthopaedic injury can lead to decreased physical activity. Valid measures for assessing physical activity are therefore needed in this population. The aim of this study was to determine the agreement and concordance between the International Physical Activity Questionnaire-Short Form (IPAQ) and device-measured physical activity and sitting time in orthopaedic injury patients. Adults with isolated upper or lower limb fracture ( n = 46; mean age of 40.5 years) wore two activity monitors (ActiGraph wGT3X-BT and activPAL) for 10 days, from 2 weeks post-discharge. The IPAQ was also completed for a concurrent 7-day period. Lin's concordance correlation coefficients and Bland-Altman plots were calculated to compare walking/stepping time, total METmins, and sitting time. The IPAQ overestimated device-derived walking time (mean difference = 2.34 ± 7.33 h/week) and total METmins (mean difference = 767 ± 1659 METmins/week) and underestimated sitting time (mean difference = -2.26 ± 3.87 h/day). There was fair concordance between IPAQ-reported and device-measured walking (ρ = 0.34) and sitting time (ρ = 0.38) and moderate concordance between IPAQ-reported and device-measured METmins (ρ = 0.43). In patients with orthopaedic injury, the IPAQ overestimates physical activity and underestimates sitting time. Higher agreement was observed in the forms of activity (walking, total PA and sitting) commonly performed by this patient group., Competing Interests: The authors declare no conflict of interest.

Background: Blood collection and blood pressure (BP) measurements are routinely performed during the same consultation to assess absolute cardiovascular disease (CVD) risk. This study aimed to determine the effect of blood collection on BP and subsequent calculation of the absolute CVD risk., Methods: Forty-five participants aged 58 ± 9 years (53% male) had systolic BP (SBP) measured using clinical guideline methods (clinic SBP). Then, on a separate visit, BP was measured immediately before, during, and after blood collection. Absolute CVD risk scores were calculated (Framingham equation) using SBP from each measurement condition and compared., Results: The prevalence of low (<10%), moderate (10-15%), and high (≥15%) absolute CVD risks among the participants was 67%, 22%, and 11%, respectively, using clinic SBP. SBP values before and during blood collection were significantly higher compared to values after blood collection (130 ± 18 and 132 ± 19 vs. 126 ± 18 mm Hg; p = 0.010 and p = 0.003, respectively). However, there were no significant differences between clinic SBP (128 ± 18 mm Hg) and blood collection SBP ( p = 0.99) or the absolute CVD risk scores (7.3 ± 6.5; 7.6 ± 5.9; 7.7 ± 6.1; and 7.1 ± 5.7%, respectively; p = 0.995 for all). The mean intraclass correlation (95% CI) indicated good agreement between absolute CVD risk scores calculated with clinic SBP and each blood collection SBP (0.86 [95% CI 0.74-0.92], 0.85 [95% CI 0.71-0.91], and 0.87 [95% CI 0.76-0.93], respectively; p < 0.001, for all)., Conclusion: Absolute CVD risk calculation is not affected by use of SBP measurements recorded at the time of blood collection. Therefore, it is acceptable to collect blood and measure BP during the same consultation for absolute CVD risk assessment., (Copyright © 2020 by S. Karger AG, Basel.)
