Abstract
Introduction The association of physical activity (PA) with subclinical cardiovascular disease (CVD) is unclear. Clarifying this relationship may inform cardiovascular prevention strategies. Methods We performed a systematic review (CRD42021226089) using Medline, Embase, CINAHL and Cochrane (1 January 2000 to 1 September 2023). Studies published with adult populations exploring the relationship between objectively measured PA and subclinical CVD were included. Subclinical CVD was assessed using: ankle-brachial index (ABI); arterial stiffness; carotid artery disease; coronary artery atherosclerosis; endothelial function; and measures of cardiac structure and function. The Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) and Cochrane Risk of Bias tools were used for quality review. Results Of 68 included studies, most supported an inverse relationship between PA and subclinical CVD. Arterial stiffness was the most common outcome (n=40), and 33 studies suggested that less sedentary behaviour (SB), increased PA and/or higher intensity PA was associated with less arterial stiffness. Ten studies of carotid artery disease (total n=18), six of endothelial function (n=10), two of coronary artery disease (n=3) and all of ABI (n=6) suggested that PA or less SB is associated with less subclinical disease. Five studies assessing cardiac structure/function (n=6) suggested alterations in structure/function with PA. Conclusions PA reduces the risk of CVD events, and this systematic review demonstrates that some of the benefits may be mediated by an inverse association between PA and subclinical CVD. Interventions to increase PA are important for CVD prevention, so we provide a comprehensive overview of which surrogate outcome measures may be most useful to assess future CVD prevention interventions. PROSPERO registration number CRD42021226089.

Comparison between Carotid Distensibility-Based Vascular Age and Risk-Based Vascular Age in Middle-Aged Population Free of Cardiovascular Disease. J Clin Med 2022; 11:jcm11164931. [PMID: 36013170 PMCID: PMC9410254 DOI: 10.3390/jcm11164931] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 08/15/2022] [Accepted: 08/17/2022] [Indexed: 12/05/2022] Open
Abstract
The concept of vascular age (VA) was proposed to provide patients with an understandable explanation of cardiovascular (CV) risk and to improve the performance of prediction models. The present study compared risk-based VA derived from Framingham Risk Score (FRS) and Systematic Coronary Risk Estimation (SCORE) models with value-based VA derived from the measurement of the common carotid artery (CCA) distensibility coefficient (DC), and it assessed the impact of DC-based VA on risk reclassification. In 528 middle-aged individuals apparently free of CV disease, DC was measured by radiofrequency-based arterial wall tracking that was previously utilised to establish sex- and age-specific reference values in a healthy population. DC-based VA represented the median value (50th percentile) for given sex in the reference population. FRS-based and SCORE-based VA was calculated as recommended. We observed a good agreement between DC-based and FRS-based VA, with a mean difference of 0.46 ± 12.2 years (p = 0.29), while the mean difference between DC-based and SCORE-based VA was higher (3.07 ± 12.7 years, p < 0.0001). When only nondiabetic individuals free of antihypertensive therapy were considered (n = 341), the mean difference dropped to 0.70 ± 12.8 years (p = 0.24). Substitution of chronological age with DC-based VA in FRS and SCORE models led to a reclassification of 28% and 49% of individuals, respectively, to the higher risk category. Our data suggest that the SCORE prediction model, in which diabetes and antihypertensive treatment are not considered, should be used as a screening tool only in healthy individuals. The use of VA derived from CCA distensibility measurements could improve the performance of risk prediction models, even that of the FRS model, as it might integrate risk prediction with additional risk factors participating in vascular ageing, unique to each individual. Prospective studies are needed to validate the role of DC-based VA in risk prediction.

Association of physical activity with vascular aging in a population with intermediate cardiovascular risk, analysis by sex: MARK study. Biol Sex Differ 2022; 13:46. [PMID: 35987700 PMCID: PMC9392339 DOI: 10.1186/s13293-022-00456-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Accepted: 08/13/2022] [Indexed: 11/10/2022] Open
Abstract
Background The aim of this study was to analyze the association of physical activity and its intensity with arterial stiffness and vascular aging and differences by sex in a Spanish population with intermediate cardiovascular risk. Methods Cross-sectional study. A total of 2475 individuals aged 35–75 years participated in the study. Brachial–ankle pulse wave velocity (baPWV) was measured using a VaSera VS-1500® device. Based on the age and sex percentile presented by the participants, the latter were classified as follows: those with a percentile above 90 and presenting established cardiovascular disease were classified as early vascular aging (EVA); those with a percentile between 10 and 90 were classified as normal vascular aging (NVA) and those with a percentile below 10 were classified as healthy vascular aging (HVA). Physical activity was analyzed through the short version of the Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ). Results The mean age of the participants was 61.34 ± 7.70 years, with 61.60% men. Of the total sample, 86% were sedentary (83% men vs 90% women). The total physical activity showed a negative association with baPWV (β = − 0.045; 95% CI − 0.080 to − 0.009). Intense physical activity showed a negative relationship with baPWV (β = − 0.084; 95% CI − 0.136 to − 0.032). The OR of the total physical activity and the intense physical activity carried out by the subjects classified as NVA with respect to those classified as HVA was OR = 0.946; (95% CI 0.898 to 0.997) and OR = 0.903; (95% CI 0.840 to 0.971), and of those classified as EVA it was OR = 0.916; (95% CI 0.852 to 0.986) and OR = 0.905; (95% CI 0.818 to 1.000). No association was found with moderate- or low-intensity physical activity. Conclusions The results of this study suggest that, when intense physical activity is performed, the probability of presenting vascular aging is lower. In the analysis by sex, this association is only observed in men. Supplementary Information The online version contains supplementary material available at 10.1186/s13293-022-00456-w. This study is the first to find a negative association between total physical activity and arterial stiffness and vascular aging in adults with intermediate cardiovascular risk. This study also shows that the association of physical activity with arterial stiffness and vascular aging in adults with intermediate cardiovascular risk varies depending on its intensity, with a negative association being found only with intense physical activity. In the analysis by sex, the results found suggest that the association is greater in men.

Aging-Related Moderation of the Link Between Compliance With International Physical Activity Recommendations and the Hemodynamic, Structural, and Functional Arterial Status of 3,619 Subjects Aged 3–90 Years. Front Sports Act Living 2022; 4:800249. [PMID: 35265833 PMCID: PMC8899126 DOI: 10.3389/fspor.2022.800249] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 01/11/2022] [Indexed: 12/16/2022] Open
Abstract
Background Compliance with physical activity recommendations (CPARs) is associated with better health indicators. However, there are only few studies to date that have comprehensively analyzed the association between CPARs and cardiovascular status “as a whole” (e.g., analyzing hemodynamic, structural, and functional properties, and different arterial territories). The relationship between CPARs and cardiovascular properties could be strongly influenced by the growth and aging process. Aim The goal of the study is to investigate the association between CPAR and cardiovascular properties by placing special emphasis on: (i) identifying if there is an independent association, (ii) if the association is “moderated” by age, and (iii) to what extent the association depends on the arterial parameter (hemodynamic vs. structural vs. functional) and/or the arterial segment (e.g., central vs. peripheral; elastic vs. transitional vs. muscular arteries). Methods A total of 3,619 subjects (3–90 years of age) were studied. Extensive cardiovascular evaluations were performed. Cardiovascular risk factors (CRFs) and physical activity (PA) levels were determined. The subjects were categorized as compliant (n = 1, 969) or non-compliant (n = 1,650) with World Health Organization-related PA recommendations. Correlation and multiple regression models (including CPAR*Age interaction) were obtained, and Johnson-Neyman technique was used to produce regions of significance. Results The independent association between CPARs and cardiovascular characteristics were strongly moderated by age. The moderation was observed on a wide range of age but particularly notorious on the extremes of life. Certain arterial characteristics demonstrated opposite effects in relation to CPAR status depending on the range of age considered. The association between CPAR and cardiovascular characteristics was independent of CRFs and moderated by age. In subjects younger than 45–55 years, CPAR status was associated with lower central and peripheral blood pressure (i.e., the younger the subject, the higher the reduction). During adult life, as age increases in the subjects, CPARs was associated with a beneficial hemodynamic profile, which is not related with variations in pressure but strongly related with lower levels of waveform-derived indexes and ventricular afterload determinants. Conclusions The independent associations between CPARs and arterial properties were strongly moderated by age. Data provided by blood pressure levels and waveform-derived indexes would be enough to evaluate the independent association between CPARs and the vascular system in the general population.

Abstract
Background: Carotid intima-media thickness (cIMT) and stiffness (cS) are predictive markers of early vascular aging and atherosclerotic risk. This study assessed, whether exercise has protective effects on carotid structure and function or on vascular risk in the young. Methods: Volume and change of exercise (recreational and organized sports participation) of German adolescents and young adults was assessed within the prospective population-study KiGGS at KiGGS-Wave-1 (2009-2012) and KiGGS-Wave-2 (2014-2017) using standardized self-reporting questionnaires. CIMT and cS were measured by real-time B-mode ultrasound sequences with semi-automated edge-detection and automatic electrocardiogram-gated quality control in 2,893 participants (14-28 years, 49.6% female). A cumulative index for atherosclerotic risk (CV-R) included z-scores of mean arterial pressure, triglycerides, total/HDL-cholesterol-ratio, body mass index, and HbA1c. Results: At KiGGS-Wave-2 cross-sectional CV-R but not cS and cIMT was lower in all exercise-groups compared to "no exercise" (B = -0.73, 95%-CI = -1.26 to 0.19, p = 0.008). Longitudinal volume of exercise was negatively associated with CV-R (B = -0.37, 95%-CI = -0.74 to 0.00, p = 0.048) but not with cS and cIMT. Cross-sectional relative risk of elevated CV-R but not cS and cIMT was lower in all exercise-groups compared to "no exercise" (RR = 0.80, 95%-CI = 0.66 to 0.98, p = 0.033). High exercise volumes were associated with lower relative risk of elevated CV-R (RR = 0.80, 95%-CI = 0.65-0.97, p = 0.021) and cS in tendency but not with cIMT. Conclusions: Increased levels of exercise are associated with a better cardiovascular risk profile in young individuals, but not with cS and cIMT. Our study confirms previous recommendations on exercise in this age group without demonstrating a clear benefit on surrogate markers of vascular health.

Abstract
Background Regular exercise training represents an important modifier of arterial stiffness (AS). Therefore, sex‐specific relations between domains of physical activity (PA; commuting, domestic, and leisure‐time PA, including active sport and occupational PA) with AS were investigated. Methods and Results Stiffness index by digital photoplethysmography was investigated in 12 650 subjects from the GHS (Gutenberg Health Study). Self‐reported PA was evaluated by the “Short Questionnaire to Assess Health‐Enhancing Physical Activity” and reported as activity score peer week, being a combined measure of duration, frequency, and intensity of PA. Multivariable linear regression analysis demonstrated strong beneficial effects of repetitive activities, such as active commuting or leisure‐time PA–related walking on AS in men, but not in women. Lower AS associated with endurance training was also found among men and premenopausal women. In contrast, intense occupational PA was related to stiffer vessels in men (P<0.0001) and women (P=0.0021) in a fully adjusted model. Combination of both, performing endurance training and having stiffness index values below median, resulted in the best survival. In contrast, subjects with elevated stiffness index at baseline without any endurance activities demonstrated the worst survival. Conclusions In this population representative sample, a differential impact of domains of self‐reported PA on AS was demonstrated. Our data strengthen the importance of regular endurance PA to induce a reduction of AS, which, in turn, may improve cardiovascular prognosis. We also report deleterious effects of intense occupational PA on stiffness index, a finding that needs further confirmation by larger prospective trials.

Abstract
STUDY OBJECTIVES Vascular dysfunction is a hypothesized mechanism linking poor sleep habits to an increased incidence of cardiovascular diseases (CVDs). However, the vascular profile associated with free-living sleep duration and sleep regularity has not been well elucidated, particularly in young adults. Thus, this study aimed to evaluate the associations between mean sleep duration, regularity in sleep duration, and peripheral vascular function in young adult college students. METHODS Fifty-one healthy undergraduate students (20 ± 1 years) completed 14 days of 24-hour wrist actigraphy and subsequent vascular assessments. Macrovascular function was measured using brachial artery flow-mediated dilation (FMD) while microvascular function was measured via passive leg movement (PLM). RESULTS Mean sleep duration was unrelated to FMD and PLM. Conversely, more irregular sleep duration (14-day sleep duration standard deviation [SD]) was unfavorably associated with all three measures of PLM-induced hyperemia (peak leg blood flow [LBF], p = 0.01; change in LBF from baseline to peak, p < 0.01; LBF area under the curve, p < 0.01), and remained significant in regression models which adjusted for sex, body mass index, blood pressure, physical activity, alcohol and caffeine consumption, and sleep duration (all p < 0.05). When using a median split to dichotomize "low" and "high" sleep duration SD groups, those demonstrating high variability in sleep duration exhibited ~45% lower PLM responses compared with those demonstrating low variability. CONCLUSIONS Irregular sleep duration is associated with poorer microvascular function as early as young adulthood. These findings support the growing body of evidence that irregular sleep patterns may be an independent and modifiable risk factor for CVD.

Abstract
OBJECTIVE To examine associations between physical activity (PA), inflammation, coronary artery calcification (CAC), and incident coronary heart disease (CHD) in African Americans. METHODS Among Jackson Heart Study participants without prevalent CHD at baseline (n=4295), we examined the relationships between PA and high-sensitivity C-reactive protein, the presence of CAC (Agatston score ≥100), and incident CHD. Based on the American Heart Association's Life's Simple 7 metrics, participants were classified as having poor, intermediate, or ideal PA. RESULTS After adjustment for possible confounding factors, ideal PA was associated with lower high-sensitivity C-reactive protein levels (β, -0.15; 95% CI, -0.15 to -0.002) and a lower prevalence of CAC (odds ratio, 0.70; 95% CI, 0.51-0.96) compared with poor PA. During a median of 12.8 years of follow-up, there were 164 incident CHD events (3.3/1000 person-years). Ideal PA was associated with a lower rate of incident CHD compared with poor PA (hazard ratio, 0.55; 95% CI, 0.31-0.98). CONCLUSION In a large community-based African American cohort, ideal PA was associated with lower inflammation levels, a lower prevalence of CAC, and a lower rate of incident CHD. These findings suggest that promotion of ideal PA may be an important way to reduce the risk of subclinical and future clinical CHD in African Americans.

Abstract
Oral contraceptive (OC) intake seems to be associated with increased central hemodynamics and arterial stiffness. Conversely, physical activity (PA) is known to induce benefits on vascular structure and function, suggesting that the negative effects of the OC pill could be counterbalanced by regular PA. The aim of this cross-sectional study was to determine (1) whether OC intake in young women is associated with higher values of hemodynamic parameters and arterial stiffness and (2) whether these negative effects could be counterbalanced by regular physical activity. Forty-nine young healthy women (21.9 years ± 2.1) were recruited and divided into 4 groups, depending on their hormonal status (OC users: OC+ or non-OC users: OC−) and their physical habits (active/inactive). Assessments of central hemodynamics (central blood pressure, Aix75) and pulse wave velocity (PWV) were performed using applanation tonometry. cBP was higher in OC+ vs. OC−, while PWV was similar between these two groups. No interaction between physical activity and hormonal status was observed for any of these variables. Nevertheless, PWV was lower in young active women compared with age-matched inactive women, suggesting that the positive effect of regular physical exercise on the cardiovascular system is already visible in the first years of women’s adulthood, whatever the hormonal status.

Abstract
[Purpose] Physical inactivity behavior at middle age or older is a major risk factor for cardiovascular disease. However, the effects of levels of habitual physical activity on arterial stiffness in elderly population remain unclear currently. Therefore, the purpose of this study was to demonstrate whether the effects of habitual physical activity could attenuate arterial stiffness in elderly individuals via a meta-analysis. [Methods] We searched the Medline and Embase databases from January 1997 through November 2017, using the medical subject headings “older population”, “physical activity” (e.g., walking, cycling, climbing, and any participation in sports), “arterial stiffness”, “pulse wave velocity”, and “cardiovascular health” published in English. Six articles (2,932 participants) were included in this meta-analysis. We investigated the effects of habitual physical activity on arterial stiffness, which was measured by the pulse wave velocity. [Results] Results confirmed heterogeneity (Q-value = 160.691, p = 0.000, I2 = 96.888) between individual studies. The effect size was calculated using random effect model. It has shown that physically active individuals have significantly lower arterial stiffness than their sedentary peers do (standardized mean difference: -1.017 ± 0.340, 95% confidence interval: -1.684 ~ -0.350, p = 0.003). [Conclusion] Findings of our systematic review and meta-analysis indicate that habitual physical activity can significantly ameliorate arterial stiffness in the elderly population.

Abstract
Background: Migraine is associated with increased cardiovascular risk and vascular dysfunction. Since aerobic exercise can reduce cardiovascular risk, the present randomized controlled trail aimed at investigating the effects of high-intensity interval training (HIT) vs. moderate continuous exercise training (MCT) on arterial stiffness in migraine patients. Methods: Forty-eight episodic migraineurs were initially enrolled in the study. 37 patients [female: 30; age: 37 (SD: 10); BMI: 23.1 (5.2); Migraine days per month: 3.7 (2.5)] completed the intervention. Central blood pressure, pulse wave reflection, and aortic pulse wave velocity (PWV) were obtained by an oscillometric monitor. Incremental treadmill exercise testing yielded maximal and submaximal fitness parameters. Participants were randomly assigned to either HIT, MCT, or a control group (CON). The intervention groups trained twice a week over a 12-week intervention period. Results: After adjustment for between-group baseline differences, a moderate meaningful overall reduction of the augmentation index at 75 min−1 heart rate (AIx@75) was observed [partial eta squared (ηp2) = 0.16; p = 0.06]. With 91% likely beneficial effects, HIT was more effective in reducing AIx@75 than MCT [HIT: pre 22.0 (9.7), post 14.9 (13.0), standardized mean difference (SMD) = 0.62; MCT: pre 16.6 (8.5), post 21.3 (10.4), SMD −0.49]. HIT induced a relevant reduction in central systolic blood pressure [cSBP: pre 118 (23) mmHg, post 110 (16) mmHg, SMD = 0.42] with a 59% possibly beneficial effect compared to CON, while MCT showed larger effects in lowering central diastolic blood pressure [pre 78 (7) mmHg, post 74 (7) mmHg, SMD = 0.61], presenting 60% possibly beneficial effects compared to CON. Central aortic PWV showed no changes in any of the three groups. Migraine days were reduced more successfully by HIT than MCT (HIT: SMD = 1.05; MCT: SMD = 0.43). Conclusion: HIT but not MCT reduces AIx@75 as a measure of pulse wave reflection and indirect marker of systemic arterial stiffness. Both exercise modalities beneficially affect central blood pressure. HIT proved to be an effective complementary treatment option to reduce vascular dysfunction and blood pressure in migraineurs.

Abstract
Obstructive sleep apnea syndrome (OSA) is associated with increased vascular morbidity. Accelerated atherosclerosis might be one of the most important mechanisms linking OSA with the development of vascular disorders. Homocysteine (HCY) and vitamin D has been associated with atherogenesis. The aim of this study was to assess a possible association between the levels of HCY and vitamin D and the carotid intima-media thickness (cIMT), which is a known marker for subclinical atherosclerosis in patients with OSA. We prospectively enrolled 110 patients with the history of snoring, who underwent standard overnight polysomnography. Clinical characteristics of the population were recorded on admission and blood samples were obtained in the fasting condition following morning. Extracranial cIMT measurements were performed according to the standardized scanning protocol. A significant correlation was found between cIMT and apnea-hypopnea index (r = .276, p = .006), age (r = .486, p < .001), diabetes mellitus (r = .377, p < .001), coronary artery disease (r = .274, p = .006) and history of stroke (r = .251, p = .012). We failed to find any significant correlation between cIMT and the levels of HCY (r = .036, p = .724) or vitamin D (r = .027, p = .800). In conclusion, our data suggest that the association of cIMT with the severity of OSA can be influenced by multiple metabolic consequences of OSA including traditional and non-traditional risk factors. HCY and vitamin D do not seem to play a superior role in this process.

Abstract
Arterial stiffness results from a degenerative process affecting mainly the extracellular matrix of elastic arteries under the effect of aging and risk factors. Changes in extracellular matrix proteins and in the mechanical properties of the vessel wall related to arterial stiffening may activate number of mechanisms involved also in the process of atherosclerosis. Several noninvasive methods are now available to estimate large artery stiffness in the clinical setting, including carotid-femoral pulse wave velocity, the reference for aortic stiffness estimate, and local distensibility measures of superficial arteries, namely carotid and femoral. An independent predictive value of arterial stiffness for cardiovascular events has been demonstrated in general as well as in selected populations, and reference values adjusted for age and blood pressure have been established. Thus, arterial stiffness is emerging as an interesting tissue biomarker for cardiovascular risk stratification and estimation of the individual "biological age". This paper overviews the mechanisms accounting for development and progression of arterial stiffness and for associations between arterial stiffness, atherosclerotic burden and incident cardiovascular events, summarizes the evidence and caveat for clinical use of stiffness as surrogate marker of cardiovascular risk, and briefly outlines some emerging methods for large artery stiffness characterization.

Abstract
Background: Carotid Intima Media Thickness (IMT) is currently used to assess the relationship between progression of coronary and systemic atherosclerosis. To date, however, the possible impact of regular physical activity (PA) on this parameter has not been well estimated. Objectives: Our study aims to examine this aspect especially in the absence of cardiovascular (CV) risk factors. Patients and Methods: 100 master athletes (MA) and 51 sedentary controls (SC) were enrolled. They were evaluated by echo test with dedicated software (QIMT-Esaote) for IMT, and Bruce protocol and 2D echocardiography for cardiac hemodynamic parameters. Results: All values were within normal range. Left IMT mean values were significantly higher than right IMT values in both MA and SC groups (MA: IMT left 635 ± 104 µ, IMT right 614 ± 104 µ and mean IMT 624 ± 91.9 µ; SC: IMT left 633 ± 78 µ, IMT right 622 ± 90 µ and mean IMT 627 ± 78.1 µ). A positive relationship was found in both groups between IMT mean values and age (P < 0.01) and between IMT mean values and peak systolic blood pressure (MA: 0.28 R, P < 0.01; SC: 0.32 R, P < 0.05). At rest, only in MA was a significant relationship evident, between mean arterial pressure value and IMT (P < 0.01). Conclusions: In the absence of CV risk factors, only age is associated with a slight increase of wall carotid thickening. The data are indicative of a physiological increase in IMT, as a consequence of increased peak effort systolic pressure after regular PA in athletes.

Abstract
BACKGROUND If the positive impact of cardiac rehabilitation on metabolic profile and exercise tolerance is well documented in the literature, very few studies evaluated the impact of these rehabilitation programs on arterial rigidity. PURPOSE The main objective of this study was to determine if a short and intense 4-week cardiac rehabilitation program could yield a positive impact on arterial rigidity. METHOD A cohort study was performed on Leopold Bellan Foundation. All patients referred for cardiac rehabilitation program after an acute event (surgery, technical gesture or acute decompensate heart failure) were included in this study. Our CR program consists of four sessions per week for five weeks (total of 20 sessions) and includes both exercise and health and nutrition education sessions. In addition to clinical and therapeutic data collection, biochemical analysis for carbohydrate and lipid metabolism and exercise capacity measurements, carotid femoral pulse wave velocity (PWV) were measured in a quiet room in the morning of their first and last day prior to any exercise. RESULTS One hundred and ninety-eight cardiac patients have participated in this study, of which 79% were male, mean age 60 ± 10, 50 (25%) were diabetic, 103 (52%) were hypertensive, 60 (30%) were current smokers, 98 (50%) had dyslipidemia, and 140 (71%) were referred for cardiac rehabilitation after acute coronary syndrome. Arterial stiffness is defined by a VPWV value greater or equal to 10. At the beginning, 59% of our patients have rigid arteries. After 20 sessions of cardiac rehabilitation, this number is significantly reduced to 51% (P=0.12). Patients with arterial stiffness have accumulated more major cardiovascular risk factors, and have had less exercise capacity than others. However they benefit similarly from the cardiovascular rehabilitation program. CONCLUSION In the present study, we observed that arterial stiffness, as reflected by the PWV, tends to decrease after short-term ambulatory cardiac rehabilitation program.

Abstract
Alterations in cerebrovascular structure and function may underlie the most common age-associated cognitive, psychiatric, and neurological conditions presented by older adults. Although much remains to understand, existing research suggests several age-associated detrimental conditions may be mediated through sometimes subtle small vessel-induced damage to the cerebral white matter. Here we review a selected portion of the vast work that demonstrates links between changes in vascular and neural health as a function of advancing age, and how even changes in low-to-moderate risk individuals, potentially beginning early in the adult age-span, may have an important impact on functional status in late life.

Abstract
Physical activity seems to enhance cardiovascular fitness during the course of the lifecycle, improve blood pressure, and is associated with decreased prevalence of hypertension and coronary heart disease. It may also delay or prevent age-related increases in arterial stiffness. It is unclear if specific exercise types (aerobic, resistance, or combination) have a better effect on blood pressure and vascular function. This review was written based on previous original articles, systematic reviews, and meta-analyses indexed on PubMed from years 1975 to 2012 to identify studies on different types of exercise and the associations or effects on blood pressure and vascular function. In summary, aerobic exercise (30 to 40 minutes of training at 60% to 85% of predicted maximal heart rate, most days of the week) appears to significantly improve blood pressure and reduce augmentation index. Resistance training (three to four sets of eight to 12 repetitions at 10 repetition maximum, 3 days a week) appears to significantly improve blood pressure, whereas combination exercise training (15 minutes of aerobic and 15 minutes of resistance, 5 days a week) is beneficial to vascular function, but at a lower scale. Aerobic exercise seems to better benefit blood pressure and vascular function.

Abstract
BACKGROUND We conducted a study to explore the relationship between television viewing time and central hemodynamic parameters and the radial augmentation index (AIx) in adults. METHODS Random sampling was used to select 732 individuals who attended primary-care centers as subjects for the study. The self-reported time that these individuals spent in viewing television was elicited with a questionnaire and included the number of hours that they spent watching television while sitting or lying down. The subjects' physical activity was estimated through accelerometers attached to their waists. Central hemodynamic parameters and the peripheral augmentation index adjusted for a heart rate of 75 bpm (PAIx75) were measured with pulse-wave application software (A-Pulse CASP). RESULTS The subjects' systolic blood pressure (SBP) (central and peripheral), pulse pressure, and radial AIx showed significant differences between tertiles of television viewing time, with the lowest values in the first tertile (P < 0.01). After adjustment for age and sex, a multiple linear regression analysis showed an association of television viewing time with office SBP. Although the association of television viewing time with central SBP followed the same trend as for office BP, it did not reach statistical significance. After adjustment for age, sex, waist-to-height ratio, physical activity reflected by accelerometer data (counts/min), high-density lipoprotein cholesterol, smoking, antihypertensive and antidiabetic medication, and the use of lipid-lowering drugs, an increase in PAIx75 of 0.22 was estimated for each hour of increase in television viewing time (P < 0.01). CONCLUSIONS Television viewing time was directly correlated with PAIx75 in an adult population. This correlation was maintained even after adjustment for physical activity, age, sex, and other cardiovascular risk factors.

Abstract
Physical exercise is the cornerstone of cardiovascular disease treatment. The present study investigated whether exercise training affects atherosclerotic plaque composition through the modification of inflammatoryrelated pathways in apolipoprotein E knockout (apoE−/−) mice with diabetic atherosclerosis. Forty-five male apoE−/− mice were randomized into three equivalent (n=15) groups: control (CO), sedentary (SED), and exercise (EX). Diabetes was induced by streptozotocin administration. High-fat diet was administered to all groups for 12 weeks. Afterwards, CO mice were euthanatized, while the sedentary and exercise groups continued high-fat diet for 6 additional weeks. Exercising mice followed an exercise program on motorizedtreadmill (5 times/week, 60 min/session). Then, blood samples and atherosclerotic plaques in the aortic root were examined. A considerable (P<0.001) regression of the atherosclerotic lesions was observed in the exercise group (180.339±75.613×103µm2) compared to the control (325.485±72.302×103 µm2) and sedentary (340.188±159.108×103µm2) groups. We found decreased macrophages, matrix metalloproteinase-2 (MMP-2), MMP-3, MMP-8 and interleukin-6 (IL-6) concentrations (P<0.05) in the atherosclerotic plaques of the exercise group. Compared to both control and sedentary groups, exercise training significantly increased collagen (P<0.05), elastin (P<0.001), and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) (P<0.001) content in the atherosclerotic plaques. Those effects paralleled with increased fibrous cap thickness and less internal elastic lamina ruptures after exercise training (P<0.05), while body-weight and lipid parameters did not significantly change. Plasma MMP-2 and MMP-3 concentrations in atherosclerotic tissues followed a similar trend. From our study we can conclude that exercise training reduces and stabilizes atherosclerotic lesions in apoE−/− mice with diabetic atherosclerosis. A favorable modification of the inflammatory regulators seems to explain those beneficial effects.

Abstract
BACKGROUND Regular exercise is associated with a reduction in cardiovascular risk, but the precise mechanisms responsible are unknown. The aim of the current study was to examine the relationship between regular exercise, aortic stiffness, and wave reflections, and to determine whether this relationship differs by age. METHODS Younger (<30 years) and older (>50 years) individuals, who were either sedentary or undertook regular aerobic exercise, were drawn from the Anglo-Cardiff Collaborative Trial population. This yielded 1,036 individuals, all of whom were nonsmokers, and were free of cardiovascular disease and medication. All individuals undertook a detailed lifestyle and medical history questionnaire including details of physical activity. Brachial and central blood pressure, together with aortic stiffness, wave reflections, cardiac output, and peripheral vascular resistance were assessed in all individuals. RESULTS In younger individuals, regular exercise was associated with lower diastolic blood pressure but elevated pulse pressure. In contrast, both systolic and pulse pressure were lower in older active individuals, compared with their sedentary counterparts. Moreover, regular exercise was associated with lower wave reflections and peripheral vascular resistance in younger individuals, but lower large artery stiffness in older individuals. CONCLUSIONS These data suggest that regular exercise is associated with a beneficial vascular profile. However, this differs between younger and older individuals such that the smaller preresistance and resistance vessels are involved in younger individuals whereas the large elastic arteries are involved in older individuals. Despite these differential findings, the current data provide support for strategies that increase habitual physical activity levels in the general population.

Abstract
OBJECTIVES This study addressed the relationship between spontaneous baroreflex sensitivity and carotid mechanical properties in a clinical setting. METHODS In 191 normal volunteers (age range 20-60 years, mean 44 ± 13), spontaneous indices of baroreflex regulation were obtained noninvasively in the time (baroreflex slope, BRS) and frequency domains (α index and systolic arterial pressure-RR interval transfer gain) as well as using an exogenous autoregressive causal model (A.XAR); carotid mechanical properties were estimated by ultrasound. The link between mechanical measures and spontaneous baroreflex indices was explored by multivariate analysis and linear modeling. RESULTS Participants were divided into five groups according to age decades. With advancing age we observed a decrease in spontaneous baroreflex indices (BRS from 31.2 to 16.3; α index from 27.4 to 13.6; RR-SAP gain at high frequency from 31 ± 3.0 to 14 ± 3.0 ms/mmHg all P < 0.001) and increase in carotid intima-media thickness (IMT: from 0.53 to 0.69 mm; P < 0.001) and stiffness (local wave speed: from 4.0 to 6.9 m/s; both P < 0.001). A significant correlation was found between spontaneous indices of baroreflex sensitivity and carotid mechanical properties, particularly wave speed (r = -0.328, P < 0.001). After adjusting for age and sex, a significant correlation remained between RR-SAP gain and wave speed and between A.XAR and IMT. Factor analysis and automatic linear modeling confirmed the observation that mechanical carotid properties are strong predictors of the age-related reduction of spontaneous baroreflex. CONCLUSION A significant correlation between spontaneous baroreflex indices and local carotid mechanical properties supports the idea that they should be considered in the physiology of baroreflex regulation.

Abstract
Circulating bone-marrow-derived cells, named endothelial progenitor cells (EPCs), are capable of maintaining, generating, and replacing terminally differentiated cells within their own specific tissue as a consequence of physiological cell turnover or tissue damage due to injury. Endothelium maintenance and restoration of normal endothelial cell function is guaranteed by a complex physiological procedure in which EPCs play a significant role. Decreased number of peripheral blood EPCs has been associated with endothelial dysfunction and high cardiovascular risk. In this review, we initially report current knowledge with regard to the role of EPCs in healthy subjects and the clinical value of EPCs in different disease populations such as arterial hypertension, obstructive sleep-apnea syndrome, obesity, diabetes mellitus, peripheral arterial disease, coronary artery disease, pulmonary hypertension, and heart failure. Recent studies have introduced the novel concept that physical activity, either performed as a single exercise session or performed as part of an exercise training program, results in a significant increase of circulating EPCs. In the second part of this review we provide preliminary evidence from recent studies investigating the effects of acute and long-term exercise in healthy subjects and athletes as well as in disease populations.

Abstract
Thickening of the carotid artery wall has been adopted as a surrogate marker of pre-clinical atherosclerosis, which is strongly related to increased cardiovascular risk. The cardioprotective effects of exercise training, including direct effects on vascular function and lumen dimension, have been consistently reported in asymptomatic subjects and those with cardiovascular risk factors and diseases. In the present review, we summarize evidence pertaining to the impact of exercise and physical activity on arterial wall remodelling of the carotid artery and peripheral arteries in the upper and lower limbs. We consider the potential role of exercise intensity, duration and modality in the context of putative mechanisms involved in wall remodelling, including haemodynamic forces. Finally, we discuss the impact of exercise training in terms of primary prevention of wall thickening in healthy subjects and remodelling of arteries in subjects with existing cardiovascular disease and risk factors.

Abstract
Foram avaliadas as repercussões tardias da desnutrição multicarencial imposta no período de aleitamento e os possíveis efeitos e/ou alterações tanto do processo de envelhecimento como do treinamento físico aeróbio moderado sobre o diâmetro luminal e a área da túnica média da parede das artérias carótida comum esquerda, aorta horizontal e aorta torácica de ratos em processo de envelhecimento. Vinte e quatro ratos machos, Wistar, foram separados de acordo com a dieta e o treinamento físico em: GNS - nutrido sedentário, GNT - nutrido treinado, GDS - desnutrido sedentário e GDT - desnutrido treinado. Aos 10 meses, o GNT e o GDT foram submetidos ao treinamento, em meio aquático, durante oito semanas. Em seguida, os ratos foram anestesiados, sacrificados e, posteriormente, foram coletados fragmentos arteriais para o processamento histológico. A área da túnica média foi mensurada através da diferença entre as áreas externa e interna da parede arterial e o diâmetro luminal foi mensurado a partir da média de dois diâmetros medidos a partir de quatro pontos marcados na camada interna do vaso. A área da túnica média apresentou redução na aorta horizontal quando comparamos os grupos GNS x GDS (p = 0,015) e um aumento da artéria carótida comum esquerda entre os grupos GNT e GNS (p < 0,001). A aorta torácica apresentou um aumento do diâmetro luminal ao compararmos o GDS com o GDT (p= 0,041). Tanto a desnutrição multicarencial induziu alterações parciais na parede aorta horizontal, como também o treinamento físico foi capaz de promover mudanças na área da túnica média da artéria carótida comum esquerda e no diâmetro luminal da aorta torácica.

Abstract
BACKGROUND In patients with hypertrophic cardiomyopathy (HCM) an impaired microvascular function is reported not only in the hypertrophied septum but also in the nonhypertrophied left ventricular free wall as well as in forearm resistance vessels, thus suggesting a generalized alteration in vascular function. However, information on conduit artery involvement is still sparse and controversial. The aim of this study was to evaluate whether functional abnormalities are detectable in the arteries of HCM patients. METHODS In a group of newly diagnosed, previously untreated, patients with nonobstructive HCM, conduit artery endothelium dependent and independent vasodilation (EDV and NEDV, respectively) were assessed with high resolution ultrasound by measuring respectively flow-mediated vasodilation and response to sublingual nitroglycerine of the brachial artery. Normotensive subjects free of cardiovascular disease and risk factors and untreated hypertensive patients with left ventricular hypertrophy were studied as control groups. RESULTS Compared to normotensives, HCM patients showed significantly blunted NEDV (13 ± 6% vs. 23 ± 7%, P < 0.01), whereas EDV was not significantly different between the two groups (11 ± 4 for HCM vs. 13 ± 4% for normotensives, P = 0.25). In the hypertensive group, both NEDV and EDV were significantly decreased compared to normotensives (P = 0.01 and P < 0.01, respectively). CONCLUSIONS Patients with HCM show a reduced vasodilator response of systemic conduit arteries to nitroglycerine, suggesting a remodeling of vascular wall or smooth muscle cell dysfunction.

Abstract
BACKGROUND It remains unclear whether the impact of habitual physical activity (HPA) differs for central vs. peripheral arterial stiffness, both of which are detrimental to cardiovascular health. We investigated the associations of lifetime HPA of different intensities on brachial and femoral stiffness in young adults, and compared these with those previously obtained for the carotid artery in the same study population. METHODS Prospectively measured data (eight repeated measures between ages 13 and 36 years) on HPAs, and other lifestyle and biological variables, were retrieved for 373 subjects in whom stiffness of the brachial and femoral, as well as the carotid, arteries was assessed at age 36 years. Generalized estimating equations were used to examine the differences in time spent in HPAs (min/week) across sex-specific tertiles of the brachial and femoral distensibility (DC) and compliance (CC) coefficients. RESULTS After adjustment for potential confounders, subjects in the highest (more compliant) vs. those in the lowest tertiles of the brachial and femoral CCs (less compliant) at age 36 years had spent on average more time in vigorous (+21.2 (95%CI:2.0; 40.4) and +24.4 (5.0; 43.8), respectively) but not in light-to-moderate HPAs throughout the longitudinal period. These differences were explained by 28 and 62%, respectively, by vigorous-HPA-related favorable impacts on other cardiovascular risk factors. No such associations were observed for the brachial and femoral DCs, however. CONCLUSIONS Lifetime vigorous, but not light-to-moderate, HPA is favorably associated with brachial and femoral compliance, but not DC. Altogether, these and our previous findings thus suggest generalized vigorous-HPA-related adaptations, although of different nature, throughout the arterial tree.

Abstract
Habitual moderate-to-vigorous-intensity physical activity attenuates arterial stiffening. However, it is unclear whether light physical activity also attenuates arterial stiffening. It is also unclear whether light physical activity has the same effects in fit and unfit individuals. This cross-sectional study was performed to determine the relationships between amount of light physical activity determined with a triaxial accelerometer and arterial stiffness. A total of 538 healthy men and women participated in this study. Subjects in each age category were divided into either high-light or low-light physical activity groups based on daily time spent in light physical activity. Arterial stiffness was measured by carotid-femoral pulse wave velocity. Two-way ANOVA indicated a significant interaction between age and time spent in light physical activity in determining carotid-femoral pulse wave velocity (P<0.05). In the older group, carotid femoral pulse wave velocity was higher in the low-light physical activity level group than in the high-light physical activity level group (945+/-19 versus 882+/-16 cm/s; P<0.01). The difference remained significant after normalizing carotid-femoral pulse wave velocity for amounts of moderate and vigorous physical activity. The carotid-femoral pulse wave velocity (r=-0.47; P<0.01) was correlated with daily time spent in light physical activity in older unfit subjects. No relationship was observed in older fit subjects. These results suggested that longer time spent in light physical activity is associated with attenuation of arterial stiffening, especially in unfit older people.

Abstract
Higher levels of habitual physical activity favorably impact on arterial stiffness. It is not clear, however, whether lifetime habitual physical activities of different intensities carry the same protective effect and to what extent any such effect is mediated by other biological cardiovascular risk factors. We, therefore, examined longitudinal data on habitual physical activity and cardiovascular risk factors (8 repeated measures between the ages of 13 and 36 years) in 373 subjects in whom stiffness estimates of the carotid artery were assessed at age 36 years using noninvasive ultrasonography. The time spent in habitual physical activities (in minutes per week) throughout the longitudinal period was compared between subjects across tertiles of the following stiffness estimates: beta-stiffness index, distensibility and compliance coefficients, and the Young's elastic modulus. After adjustments for sex, body height, and other lifestyle variables, subjects in the highest tertile of the beta-stiffness index (ie, with stiffer arteries) had spent, on average, throughout the longitudinal period, less time in vigorous (-26.5 [95% CI: -45.9 to -7.1]) but less so in light-to-moderate habitual physical activities (-11.2 [95% CI: -53.5 to 31.1]) as compared with subjects in the lowest tertile. The difference in time spent in vigorous activities was greatly attenuated when further adjusted for blood lipids, cardiorespiratory fitness, fat distribution, resting heart rate, and mean arterial pressure (to -11.2 [95% CI: -29.4 to 7.0]). Similar results were found for the other stiffness estimates. Promoting vigorous intensity physical activities among the healthy young may, therefore, prevent arterial stiffness and related cardiovascular sequelae later in life, partly through its favorable impact on other biological cardiovascular risk factors.

Abstract
The present study investigates the effect of home-based resistance training on arterial stiffness in healthy premenopausal women. Twelve healthy non-smoking and normotensive women who were not actively involved in regular physical exercise (aged 42-55 years) performed home-based resistance training twice weekly for 10 weeks using body weight and light dumbbells. Each training session required approximately 40 min to complete. Arterial stiffness was measured using brachial-ankle pulse wave velocity (baPWV). We also determined serum total cholesterol, HDL cholesterol, glucose, triglyceride, insulin, and adiponectin and calculated the homeostasis model assessment of insulin resistance (HOMA-IR), an index of insulin resistance. After home-based resistance training, baPWV, total cholesterol, LDL cholesterol, insulin, and the HOMA-IR decreased, whereas adiponectin increased (P < 0.05) and levels of HDL cholesterol, glucose, triglyceride, blood pressure, and heart rate remained unaffected. These results suggest that home-based resistance training benefits vascular function in healthy premenopausal women.

Abstract
We investigated the effect of atorvastatin monotherapy and combined treatment with atorvastatin and pioglitazone on intima-media thickness, vascular function and the cardiovascular risk profile. In all, 148 patients (76 male, 72 female; aged 61.4+/-6.5 years; body mass index [BMI] 29.2+/-4.1 kg/m2; mean +/- SD) with increased cardiovascular (CV) risk factors were randomised. Intima-media thickness (IMT), the augmentation index (Aix@75), the microvascular response to acetylcholine (LDF), lipid status, and plasma levels of intact proinsulin, adiponectin, interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), matrix metalloproteinase-9 (MMP-9), sCD40L, P-selectin, tissue plasminogen activator (t-PA) and blood lipids were monitored over six months. Atorvastatin treatment, alone and in combination with pioglitazone, revealed a significant regression in IMT (0.923+/-0.013 to 0.874+/-0.012 mm and 0.921+/-0.015 to 0.882+/-0.015 mm; mean +/- SEM; p<0.05 respectively) and Aix@75 (27.3+/-1.2 to 25.9+/-1.4; and 25.6+/-1.4 to 24.8+/-1.7%; p<0.05). The endothelial response to acetylcholine as measured by laser Doppler fluximetry (LDF) improved during combined treatment (373+/-57 to 576+/-153 AU; p<0.05). Addition of pioglitazone to atorva-statin resulted in significant further effects on high-sensitivity C-reactive protein (hsCRP), t-PA, P-selectin, adiponectin, triglycerides and high-density lipoprotein (HDL) cholesterol (p<0.05 respectively). Atorvastatin significantly improved IMT and vascular elasticity. Co-administration of pioglitazone provided additional effects on endothelial function, lipid profile and laboratory markers of inflammation.

Abstract
The subject of arterial stiffness as a modifiable risk factor is controversial and difficult to understand. The best approach here will be to assist readers to understand the issue and the basis of controversy. We also hope to show that the subject is not as overwhelming as it might appear. We believe that new blood is required in this field and that a basic understanding is necessary for researchers to be induced to take on such investigations. Our approach sets out a historic and pathophysiologic background on which modern studies can be based; describes measures and indices of arterial stiffness including pulse wave velocity, augmentation index, ambulatory arterial stiffness index, aortic impedance, and carotid elastic modulus; and finally, addresses the specifics of this interesting and important question. Although aortic stiffening with age is attributable to fracture of elastin lamellae and is largely irreversible, stiffening of muscular arteries can be modified by vasodilator drugs, and by improved endothelial function such as induced by exercise training.
