Background: Diabetes mellitus (DM) is a common metabolic disease worldwide and has many complications. The vascular events are the major complication of DM that have an important effect on mortality and disability. The physical activity (PA) enhances the vascular function by several pathways. The aim of this study was to evaluation of the relationship between PA and vascular diseases in patients with DM.Materials and Methods: This research was performed as the case-control study that was extracted from a prospective epidemiological research study in Iran (PERSIAN). The patients with type 2 DM more than six months defined as case group and the non-DM subjects in control group with ratio 1:2, and both groups were matched in the term of age and sex. The MET score was used to evaluate the level of PA and blood glucose, lipid profile, body mass index, overweight, dyslipidemia, glomerular filtration rate, myocardial infarction (MI), unstable angina, and stroke.Results: Overall, 1242 patients with DM were extracted, and 2484 non-diabetic subjects were investigated. In the case group, 355(28.6 %) and 887(71.4%) were men and women, respectively, the and 710 (28.6%) men and 1774(71.4%) women in control group. The mean MET score was 30 and 40.97 in the DM and non-DM groups, respectively (P˂0.001). The frequency of MI, stroke, and cardiac ischemia were 44 (3.5%), 37 (3%), and 267 (21.5%), respectively in DM group, and 54 (2.2%), 43 (1.7%), and 389 (15.7%), respectively in non-DM group.Conclusion: The incidence of vascular events associated with PA level in patients with DM and adherence to regular PA reduce the vascular events and DM complications.

The Relationship

Introduction: Sex differences in plaque morphology and composition exist; men develop more unstable plaques than women. Yet, stroke kills more women than men. Despite these differences, no sex-specific guidelines for carotid disease management exist. Thus, markers that reflect sex-specific morphological features in the plaque should be explored for better prediction of stroke risk. Pro-inflammatory adipokines, chemerin and resistin, influence vascular function. Herein we are the first to investigate sex differences in the relationship between carotid plaque instability and the expression of these adipokines. Methods: Subjects with ≥50% carotid stenosis scheduled for a carotid endarterectomy were recruited from McGill-affiliated hospitals. Pre-operative plasma chemerin and resistin levels were measured using ELISA. Stability of carotid plaque specimens was assessed by two gold standard histological classifications. Stable and unstable plaques were immunostained for chemerin, chemerin’s receptor (ChemR23), and resistin. Digital and semi-quantifications assessed the % area of expression as well as staining intensity (mild to high) and % of positively stained macrophages/foam cells. Plaque mRNA expression was assessed by quantitative PCR. Sex-hormone analyses are ongoing. Results: Men (n=171) had more unstable plaque features, i.e., greater hemorrhage (P=0.022), lipid core size (P<0.001), inflammation (P=0.007), cap infiltration (P=0.006), and less fibrous tissue (P<0.001) than women (n=79). Circulating chemerin and resistin levels were similar between men and women and no sex differences were observed in relation to plaque instability. The % area of chemerin and resistin staining in the plaque was greater in unstable vs stable plaques in men only (P=0.040; P=0.005, respectively). Similarly, greater intensity in chemerin, ChemR23, and resistin staining was associated with plaque instability in men only (P<0.001; P=0.013; P=0.033, respectively). In contrast, lower resistin plaque mRNA expression was associated with plaque instability in women only (P=0.040). Conclusion: Our results suggest the possibility of a sex-dependent regulatory mechanism underlying the connection between these adipokines and plaque instability.

Abstract Aims We evaluated the relationship between epicardial adipose tissue (EAT) and coronary vascular function assessed by rubidium-82 (82Rb) positron emission tomography/computed tomography (PET/CT) in patients with suspected coronary artery disease (CAD). Methods and results The study population included 270 patients with suspected CAD and normal myocardial perfusion at stress–rest 82Rb PET/CT. Coronary artery calcium (CAC) score and EAT volume were measured. Absolute myocardial blood flow (MBF) was computed in mL/min/ from the dynamic rest and stress imaging. Myocardial perfusion reserve (MPR) was defined as the ratio of hyperaemic to baseline MBF and it was considered reduced when <2. MPR was normal in 177 (65%) patients and reduced in 93 (35%). Patients with impaired MPR were older (P < 0.001) and had higher CAC score values (P = 0.033), EAT thickness (P = 0.009), and EAT volume (P < 0.001). At univariable logistic regression analysis, age, heart rate reserve (HRR), CAC score, EAT thickness, and EAT volume resulted significant predictors of reduced MPR, but only age (P = 0.002), HRR (P = 0.021), and EAT volume (P = 0.043) were independently associated with reduced MPR, at multivariable analysis. In patients with CAC score 0 (n = 114), a significant relation between EAT volume and MPR (P = 0.014) was observed, while the relationship was not significant (P = 0.21) in patients with CAC score >0 (n = 156). Conclusion In patients with suspected CAD and normal myocardial perfusion, EAT volume predicts hyperaemic MBF and reduced MPR, confirming that visceral pericardium fat may influence coronary vascular function. Thus, EAT evaluation has a potential role in the early identification of coronary vascular dysfunction.

Abstract Objectives The gut microbiota is emerging as an important regulator of cardiovascular health. Indeed, gut dysbiosis is increasingly being linked to the development of cardiovascular disease (CVD). Aging and obesity are associated with the development of CVD largely due to the development of vascular dysfunction, namely endothelial dysfunction and arterial stiffness. The objective of this study was to examine the relationship between the gut microbiota, blood pressure, and vascular function in aging overweight and obese individuals. Methods This cross-sectional study included fifteen overweight and obese (mean body mass index, BMI: 29.5; range: 25.8–37.0) middle-aged/older men and postmenopausal women (mean age: 53; range: 42–64 years). Blood pressure, arterial stiffness (augmentation index, AIx, and aortic pulse wave velocity, aPWV), and endothelial function (reactive hyperemia index, RHI) were assessed. Stool samples were collected for gut microbiota analysis using 16S ribosomal RNA sequencing. Principal coordinates analysis and Pearson's correlations were performed to evaluate the relationship between the gut microbiota and measures of vascular function and blood pressure. Results Global gut microbiota phenotypes clustered most strongly by aPWV (groups separated by median value) as visualized by Non-Metric Dimensional Scaling plot of Bray-Curtis Distances (stress = 0.09; P = 0.07). Several bacterial taxa correlated with vascular parameters. For example, Bifidobacterium longum (r = 0.80, P < 0.001) and Akkermansia muciniphila (r = 0.56, P = 0.047) were positively correlated with RHI. Bifdobacterium bifidum (r = −0.61, P = 0.02) and Oxalobacter formigenes (r = −0.62, P = 0.02) were negatively correlated with systolic blood pressure. Interestingly, there was no significant clustering by BMI groupings (overweight vs. obese) or correlations between BMI and specific taxa. Conclusions These preliminary data suggest that the gut microbiota is linked to vascular dysfunction and increased blood pressure in aging overweight and obese individuals independent of BMI. Further data collection and analysis are currently underway to explore these relationships in a larger human cohort, and to explore underlying mechanisms through transferring of vascular phenotypes in humans to germ-free mice through microbiota transplantation.

The Relationship

The aim of this study was to assess the association between peripheral arterial tonometry (PAT) and two more traditional measures of endothelial function – flow-mediated dilation (FMD) and its hyperemic stimulus, hyperemic peak velocity time integral (VTI). We related three vascular function measures (natural log transformed PAT, FMD, and VTI) from 304 patients (mean age 48.9 ± 12.5 years), including 105 with coronary artery disease (CAD). Using linear regression, we studied the relationships between lnPAT, FMD, and VTI, and compared differences in these parameters in those with and without CAD. Although FMD and lnPAT both had a correlation with VTI (Pearson’s r = 0.119, p = 0.039 and r = 0.167, p = 0.004, respectively), lnPAT had no correlation with FMD ( r = −0.0471, p = 0.414). lnPAT was also lower in patients with CAD compared to controls (mean 0.51 ± 0.19 versus 0.65 ± 0.26, respectively, p < 0.0001). In multivariate analysis, VTI remained associated with lnPAT (standardized β = 0.1369, p = 0.04). Among this group of subjects with and without CAD, lnPAT was found to be unrelated to FMD but correlated with VTI. This would suggest that lnPAT is a measure of microvascular function. Although it is unrelated to FMD, lnPAT is decreased in patients with pre-existing cardiovascular disease. Further studies are required to determine if this can be used clinically as a tool for cardiac risk stratification and prediction of CAD.

The Brain

Elucidating the brain regions and networks associated with cognitive processes has been the mainstay of task-based fMRI, under the assumption that BOLD signals are uncompromised by vascular function. This is despite the plethora of research highlighting BOLD modulations due to vascular changes induced by disease, drugs, and aging. On the other hand, BOLD fMRI-based assessment of cerebrovascular reactivity (CVR) is often used as an indicator of the brain's vascular health and has been shown to be strongly associated with cognitive function. This review paper considers the relationship between BOLD-based assessments of CVR, cognition and task-based fMRI. How the BOLD response reflects both CVR and neural activity, and how findings of altered CVR in disease and in normal physiology are associated with cognition and BOLD signal changes are discussed. These are pertinent considerations for fMRI applications aiming to understand the biological basis of cognition. Therefore, a discussion of how the acquisition of BOLD-based CVR can enhance our ability to map human brain function, with limitations and potential future directions, is presented.
