Associations between physical activity and cardiorespiratory fitness with vascular health phenotypes in older adults: a cross-sectional study. Front Physiol 2023; 14:1096139. [PMID: 37256064 PMCID: PMC10225566 DOI: 10.3389/fphys.2023.1096139] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 04/24/2023] [Indexed: 06/01/2023] Open
Abstract
Objective: We investigated the associations between physical activity (PA) and cardiorespiratory fitness (CRF) with vascular health phenotypes in community-dwelling older adults. Methods: This cross-sectional study included 82 participants (66.8 ± 5.2 years; 81% females). Moderate-to-vigorous physical activity (MVPA) was assessed using accelerometers, and CRF was measured using the distance covered in the 6-min walk test (6MWT). The vascular health markers were as follows: i) arterial function measured as aortic pulse wave velocity (aPWV) estimated using an automatic blood pressure device; and ii) arterial structure measured as the common carotid intima-media thickness (cIMT). Using a combination of normal cIMT and aPWV values, four groups of vascular health phenotypes were created: normal aPWV and cIMT, abnormal aPWV only, abnormal cIMT only, and abnormal aPWV and cIMT. Multiple linear regression was used to estimate the beta coefficients (β) and their respective 95% confidence intervals (95% CI) adjusting for BMI, and medication for diabetes, lipid, and hypertension, sex, age, and blood pressure. Results: Participants with abnormal aPWV and normal cIMT (β = -53.76; 95% CI = -97.73--9.78 m; p = 0.017), and participants with both abnormal aPWV and cIMT (β = -71.89; 95% CI = -125.46--18.31 m; p = 0.009) covered less distance in the 6MWT, although adjusting for age, sex and blood pressure decreased the strength of the association with only groups of abnormal aPWV and cIMT covering a lower 6MWT distance compared to participants with both normal aPWV and cIMT (β = -55.68 95% CI = -111.95-0.59; p = 0.052). No associations were observed between MVPA and the vascular health phenotypes. Conslusion: In summary, poor CRF, but not MVPA, is associated with the unhealthiest vascular health phenotype (abnormal aPWV/cIMT) in older adults.

Abstract
BACKGROUND Carotid-femoral pulse wave velocity (cfPWV), the referent measure of aortic stiffness, is an established measure of vascular aging. In studies where cfPWV cannot be measured, alternative methods are needed to help promote research on vascular aging. This study examines the construct validity of a measure of PWV estimated from age and blood pressure (ePWV). The specific aims of the study are to: 1) explore the strength of association between ePWV, cfPWV, and other established measures of vascular aging; 2) examine the sensitivity and specificity of elevated ePWV (≥10m/s) in relation to elevated cfPWV (≥10m/s). METHODS We measured cfPWV in two-hundred and fifty-two adults (mean age 57±12 years, 48% female) and calculated each participant's ePWV from their age and brachial blood pressure. Additional measures of vascular aging included: carotid intima-media thickness (cIMT); carotid stiffness measured as elastic modulus (cEp); and carotid augmentation index (cAIx). RESULTS The correlations between cfPWV and measures of vascular aging were: cEp (r = 0.36), cIMT (r = 0.49), and cAIx (r = 0.04). The correlations between ePWV and measures of vascular aging were: cEp (r = 0.45), cIMT (r = 0.60), and cAIx (r = 0.24). The correlation between ePWV and cfPWV was (r = 0.67). The sensitivity and specificity of elevated ePWV (≥ 10 m/s) for concomitantly identifying high cfPWV (≥ 10 m/s) were 85.4% and 73.0% respectively. CONCLUSION ePWV is associated with established measures of vascular aging, such as carotid thickness, carotid stiffness and carotid augmentation index. ePWV may be a useful tool to help promote research on vascular aging.

Effects of Anti-Inflammatory Treatment and Surgical Intervention on Endothelial Glycocalyx, Peripheral and Coronary Microcirculatory Function and Myocardial Deformation in Inflammatory Bowel Disease Patients: A Two-Arms Two-Stage Clinical Trial. Diagnostics (Basel) 2021; 11:diagnostics11060993. [PMID: 34070768 PMCID: PMC8227308 DOI: 10.3390/diagnostics11060993] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/27/2021] [Accepted: 05/28/2021] [Indexed: 02/06/2023] Open
Abstract
Sixty inflammatory bowel disease (IBD) patients (45 Crohn disease and 15 ulcerative colitis, 40 ± 13 years, 53% male) were examined at baseline and 4 months after intervention (surgical (35 patients) or anti-TNFa treatment (25 patients)). IBD severity, using Mayo score, Harvey–Bradshaw Index (HBI) and biomarkers, was correlated with cardiovascular markers. At baseline, the disease severity, the white blood cells (WBC) values and the reducing power (RP) were significantly correlated with the aortic pulse wave velocity (PWV) (r = 0.4, r = 0.44 and r = 0.48, p < 0.05) and the lateral mitral E’ velocity (r = 0.35, p < 0.05 and r = 0.3, p < 0.05). Four months after intervention, there was a reduction of WBC (1962.8/mm3 ± 0.425/mm3, p < 0.001), C-reactive protein (CRP) (8.1 mg/L ± 1.7 mg/L, p < 0.001), malondialdehyde (MDA) (0.81 nmol/mg ± 0.37, p < 0.05) and glycocalyx perfused boundary region (PBR 5-25) (0.24 μm ± 0.05 μm, p < 0.01). Moreover, the brachial flow mediated dilatation (FMD), the coronary flow reserve (CFR) and the left ventricle global longitudinal strain (LV GLS) were significantly improved for both groups (4.5% ± 0.9%, 0.55 ± 0.08, 1.4% ± 0.35%, p < 0.01), while a more significant improvement of PWV/GLS was noticed in the anti-TNFa group. IBD severity is associated with vascular endothelial, cardiac diastolic, and coronary microcirculatory dysfunction. The systemic inflammatory inhibition and the local surgical intervention lead to significant improvement in endothelial function, coronary microcirculation and myocardial deformation.

Abstract
In this study, our aim was to assess the coronary flow reserve (CFR) by performing the adenosine stress (99m)Tc-MIBI single-photon computed tomographic (SPECT) myocardial perfusion imaging in patients with hypertension. 47 hypertensive patients with normal coronary angiography were divided into 2 groups, defined by the presence (LVH, n = 22) and absence (non-LVH, n = 25) of left ventricular hypertrophy with 17 normal cases as controls. All patients were administered the adenosine stress-rest (99m)Tc-MIBI scintigraphy. 0.14 mg/kg/min adenosine was administered by continuous infusion for 6 min. We found that adenosine-induced myocardial ischemia was present in 26 cases (55.3 %) with 87 segments (20.6 %) showing abnormal distribution in the hypertensive group versus a single case (5.9 %) (χ (2) = 31.12, P < 0.001) and segment (0.7 %) (χ (2) = 32.90, P < 0.001) in the control group by SPECT perfusion. In the LVH group, 17 cases (77.3 %) and 67 segments (33.8 %) of myocardial ischemia were present. In the non-LVH group, there were 9 cases (36.0 %) (χ (2) = 8.06, P < 0.001), 20 segments (8.9 %) (χ (2) = 40.13, P < 0.001). There was a significant decrease in coronary reserve in the hypertensive groups following adenosine infusion with a fourfold decrease in cases and a sixfold decrease in segments (P < 0.001). Our study suggests that assessing CFR by the (99m)Tc-MIBI adenosine stress by SPECT imaging is a relatively easy, safe, and non-invasive test in patients with hypertension. We noted a decrease in CFR in patients with hypertension. This decrease was especially remarkable for hypertensive patients with LVH. This study shows that administering the (99m)Tc-MIBI adenosine stress by SPECT imaging is a safe, simple, and non-invasive test for detecting CFR in patients with hypertension.

Abstract
High-density lipoprotein cholesterol (HDL-C), a negative risk factor, is positively associated with a decreased risk of coronary heart disease. We investigated the association between high HDL-C levels and target organ damage (TOD) in never treated women with hypertension. We measured HDL-C levels in 117 women followed by estimation of TODs, that is, pulse wave velocity, microalbuminuria, left ventricular mass index, coronary flow reserve, and carotid intima–media thickness (cIMT). Women were divided into 2 groups (HDLH and HDLL), regarding HDL-C quartiles (upper quartile vs the first 3 lower quartiles). In HDLH group (HDL ≥70 mg/dL), cIMT was nonindependently, negatively related to HDL-C (ρ = −.42, P < .05). Using receiver –operating characteristic curve (ROC) analysis in the HDLH group, we concluded that the cutoff value of HDL ≥76.5 mg/dL moderately predicted the absence of carotid atherosclerosis (area under the curve: 0.77, P = .02; confidence interval: 0.57-0.97; sensitivity 73% and specificity 67%). Increased HDL-C may predict the absence of carotid atherosclerosis in middle-age women with untreated essential hypertension and consequently contribute to total cardiovascular risk estimation and treatment planning.

Abstract
Coronary artery disease (CAD) is a major cause of death in Japan. Coronary angiography is useful to assess the atherosclerotic burden in CAD patients, but its ability to predict whether patients will respond favorably to optimal medical therapy and revascularization is limited. The measurement of the fractional flow reserve with angiography is a well-validated method for identifying ischemic vessels. However, neither an anatomical assessment nor a functional assessment can delineate microvasculature or estimate its function. The quantitative coronary flow reserve (CFR) estimated from sequential myocardial perfusion images obtained by positron emission tomography (PET) during stress provides an accurate index of hyperemic reactivity to vasodilatory agents in the myocardium. In fact, there is growing evidence that the CFR reflects disease activity in the entire coronary circulation, including epicardial coronary artery stenosis, diffuse atherosclerosis, and microvascular dilatory function. Importantly, reduced CFR is observed even in patients without flow-limiting coronary stenosis, and its evaluation can improve the risk stratification of patients at any stage of CAD. This review focuses on the application of CFR estimated by cardiac PET for the diagnosis and risk stratification of patients with CAD.

Abstract
Inflammation has a role in the pathogenesis of atherosclerosis, which causes hypertension. Results from some studies have suggested links between periodontal disease and atherosclerosis, but links between periodontal disease and hypertension have been seldom studied. We investigated whether periodontal disease and serum antibody level were associated with hypertension. We studied 127 patients (93 men and 34 women, mean age 68±9 years) who were admitted with ischemic heart disease to our institution. A composite periodontal risk score was calculated from five periodontal vector scores. The levels of serum antibody against Porphyromonas gingivalis (Pg) were measured. Pulse pressure, mean blood pressure (BP) and pulse wave velocity were used as indices of atherosclerosis. We divided patients into two groups according to the levels of serum antibody against Pg: higher or equal to the median (high Pg antibody group) and lower than the median (low Pg antibody group).There was no difference in the use of antihypertensive agents between the two groups. The composite periodontal risk score (P=0.0003), systolic BP (P=0.030), diastolic BP (P=0.038), pulse pressure (P=0.050) and mean BP (P=0.055) were higher in the high Pg antibody group than in the low Pg antibody group. The composite periodontal risk score (r=0.320, P=0.0003), systolic BP (r=0.212, P=0.017), diastolic BP (r=0.188, P=0.035) and mean BP (r=0.225, P=0.011) correlated with the level of serum antibody against Pg, even after adjustment for age. An elevated antibody level against Pg indicates advanced periodontal disease and suggests advancement of atherosclerosis and hypertension.

Abstract
Background Many studies have attempted to develop relatively simple and easy noninvasive measurements of atherosclerosis (NIMA), and each NIMA assesses different atherosclerotic properties. We, therefore, investigated the association between metabolic syndrome (MetS) components and different NIMAs. Methods This study included 1,132 Korean subjects over 20 years of age who had visited a Health Promotion Center in Korea. Carotid injury (increased carotid intima-media thickness or plaques) was evaluated by ultrasonography and arterial stiffness by brachial-ankle pulse wave velocity. The MetS components were assessed according to the Asian criteria of the American Heart Association/National Heart, Lung, and Blood Institute. Results Both arterial stiffness and carotid injury gradually deteriorated with increase in the number of MetS components. Arterial stiffness and carotid injury were associated with different MetS components, each of which had varying impact. After adjustment for all possible confounders such as age, sex, and lifestyle, elevated blood pressure (BP) was found to have the strongest association with arterial stiffness, whereas central obesity, impaired fasting plasma glucose, and elevated BP had comparable connection with carotid atherosclerosis. Conclusion Individual MetS components were related with subclinical atherosclerosis in different ways. Elevated BP showed the strongest association with arterial stiffness, while central obesity, impaired fasting plasma glucose, and elevated BP showed good correlation with carotid atherosclerosis.

Abstract
AIMS Coronary microcirculation is disturbed in hypertensive patients. We investigated the association of coronary flow reserve (CFR) with the response of left ventricular (LV) function as assessed by tissue Doppler imaging (TDI) during adenosine stress echocardiography in never-treated hypertensive patients. METHODS AND RESULTS We studied 90 hypertensive patients and 30 control subjects, matched for age and sex, by adenosine stress echocardiography. We measured: (i) CFR, E and A Doppler, S', E', A' mitral annulus velocities with TDI, as well as the E'/A' ratio and the E/E' ratio before and during adenosine infusion (ii) the %changes of the measured indices between baseline and adenosine infusion. After adenosine infusion, there was an increase in S', E', and A' in all patients and controls (P < 0.05). Compared with controls and patients with CFR ≥ 2.5, patients with CFR <2.5 showed a smaller increase in S' (28.6 vs. 30.0 vs. 11.1%, F for interaction = 14.592) and E' (33.3 vs. 33.3 vs.1.5%, F = 28.927) as well as a decrease in E'/A' (9.2 vs. 6.4% vs. -20.0%, F = 5.128) and an increase in E/E' (-6.1 vs. -1.6 vs. 30.5%. F = 12.780) after adenosine infusion (P < 0.05 for all comparisons). CFR was independently related to %changes of TDI parameters (regression coefficient b = 0.576 for S'; b = 0.517 for E'; b = 0.473 for E'/A'; b = -0.520 for E/E', respectively, P < 0.001). By the receiver operating curve, a CFR <2.5 predicted the median changes of all measured TDI markers, with a sensitivity and specificity over 70% (AUC >75%, P < 0.05). CONCLUSION An abnormal response of the LV longitudinal function during adenosine stress echocardiography is related to impaired CFR in untreated hypertensive patients.

Abstract
It is still unclear whether silent brain infarct (SBI) and white-matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) scans are associated with cardio-ankle vascular index (CAVI), a novel parameter of arterial stiffness. We studied 220 consecutive patients (mean age, 69 years) without a history of stroke or transient ischemic attack. Patients were assessed for the presence of SBI, WMHs and risk factors. Arterial stiffness was evaluated using CAVI. Patients were categorized into one of two groups according to the presence or absence of SBI and WMHs, and clinical characteristics were compared between the two groups. CAVI was significantly higher in patients with SBI or in patients with WMHs than in those without those respective findings. The CAVI cutoff values for detection of SBI and WMHs were 9.2 and 8.9, respectively. On multivariable analyses, CAVI, a one point increase in CAVI: odds ratio (OR), 1.25; 95% confidence interval (CI), 1.01-1.56; CAVI ≥9.2: OR, 2.34; 95% CI, 1.16-5.02, was independently associated with SBI, however, CAVI was not independently associated with WMHs. Patients with CAVI ≥9.2 had higher OR for the presence of both SBI and WMHs (OR, 2.57; 95% CI, 1.15-5.98) when compared with patients with CAVI <9.2 after adjustment for age and sex. SBI is independently associated with arterial stiffness indicated by CAVI.

Abstract
Obstructive sleep apnea is a prevalent disease that is associated with significant morbidity and mortality, particularly due to cardiovascular disease. An emerging cardiovascular risk factor, arterial stiffness, may also be involved in the cardiovascular complications of obstructive sleep apnea. The purpose of this review was to summarize the current literature regarding the effect of obstructive sleep apnea on arterial stiffness. We conducted a systematic literature review using PubMed, Embase and the Cochrane Library. We identified 24 studies that met search criteria investigating the effect of obstructive sleep apnea on arterial stiffness. Arterial stiffness was found to be increased in obstructive sleep apnea patients compared with controls or increased in severe compared with mild sleep apnea. In some studies, a positive correlation was identified between the degree of arterial stiffness and sleep apnea severity. In the two randomized, controlled trials and the two nonrandomized trials identified, treatment of obstructive sleep apnea with continuous positive airway pressure led to significant decreases in arterial stiffness. Obstructive sleep apnea appears to have an independent effect on arterial stiffness, which may be one of the mechanisms accounting for sleep apnea-associated cardiovascular risk.
