Risk Biomarkers

Ceramides are a class of sphingolipids which have recently been shown to be better cardiovascular disease (CVD) risk predictors than traditional CVD risk biomarkers. Tyrosol (TYR) is a dietary phenolic compound known to possess cardioprotective effects per se or through its in vivo active metabolite hydroxytyrosol. The purpose of this study was to evaluate the effects of the co-administration of white wine (WW) and TYR on circulating levels of ceramides and other lipids in humans at high CVD risk. Volunteers underwent a randomized controlled crossover clinical trial (4-week duration per intervention) with three different interventions: control, WW, and WW enriched with a capsule of TYR (WW + TYR). Endothelial function cardiovascular biomarkers and plasma lipidomic profile were assessed before and after each intervention. It was found that the WW + TYR intervention resulted in lower levels of three ceramide ratios, associated with an improvement of endothelial function (Cer C16:0/Cer C24:0, Cer C18:0/Cer C24:0, and Cer C24:1/Cer C24:0), when compared to the control intervention. Moreover, WW + TYR was able to minimize the alterations in plasma diacylglycerols concentrations observed following WW. Overall, the results obtained show that the antioxidant TYR administered with WW exerts beneficial effects at the cardiovascular level, in part by modulating blood lipid profile.

Cell Mobilization

Cyclosporin A (CsA) improves the success rate of transplantation. The CD26/dipeptidylpeptidase IV (DPP IV) system plays a critical role in mobilizing endothelial progenitor cells (EPCs) from bone marrow. This study investigated whether CsA manipulates CD26/DPP IV activity and increases EPC mobilization. C57BL/6 mice were divided into control and CsA-treated groups. Before and after hindlimb ischemia was induced, circulating EPC number and serum levels of different cytokines were measured. Compared with the controls, CsA treatment significantly increased the blood levels of stroma-derived factor-1α and stem cell factor after ischemic stress ( P < 0.001). The CsA group displayed a significant increase in the number of circulating EPCs (sca-1+KDR+ and c-kit+CD31+ EPCs, both P < 0.05). In vivo, CsA caused a significant increase in the numbers of EPCs incorporated into the Matrigel and ischemic limbs ( P < 0.05). In the peripheral blood, CsA significantly decreased CD26+ cell numbers and attenuated the plasma CD26/DPP IV activity ( P < 0.001). Furthermore, short-term CsA treatment significantly improved the perfusion of ischemic limbs and decreased the spontaneous digital amputation rate. In summary, CsA manipulates the mobilization of EPCs into the circulation via the CD26/DPP IV system. Short-term CsA treatment has beneficial effects on angiogenesis of ischemic tissues.

Abstract Kaempferol (KPF) is a dietary polyphenol reported to have various beneficial effects on human health. However, its molecular mechanisms in regulating lipid and glucose metabolism are not fully understood. This study examined the effects of KPF on obesity, dyslipidemia, and diabetes in Tsumura, Suzuki, Obese Diabetes (TSOD) mice. The six-week administration of KPF decreased fat weight, serum total cholesterol, and low-density lipoproteins (LDLs); increased high-density lipoproteins (HDLs); and improved glucose tolerance. Additionally, KPF increased LDL receptor (LDLR) and apolipoprotein A1 (ApoA1) gene expression and decreased serum resistin levels. These findings suggest that the decrease in LDL and the increase in HDL caused by KPF may be due to increases in hepatic LDLR and ApoA1 expression, respectively. Furthermore, it is possible that the improvement in glucose tolerance by KPF may occur via resistin reduction. These mechanisms may be parts of complex mechanism by which KPF improves metabolic syndrome.

Objective: Peroxisome proliferator-activated receptor (PPAR)-α and -γ agonists modify lipid and glucose metabolism. The aim of the study was to characterize the effects of the dual PPAR-α/γ agonist aleglitazar on endothelial function, neoangiogenesis and arteriogenesis in mice and on human endothelial progenitor cells (EPC). Methods and Results: Male C57Bl/6 wild-type (WT, normal chow) and apolipoprotein E-deficient (apoE-/-) mice on Western-type diet (WTD) were treated with aleglitazar (10 mg/kg i.p.) or vehicle by daily injection. Hindlimb ischemia was induced by right femoral artery ligation (FAL). ApoE-/- mice on WTD treated with aleglitazar before FAL were characterized by an improvement of endothelial-dependent laser Doppler perfusion (right/left foot ratio 0.40±0.03) 1 week after FAL compared to controls (R/L foot ratio 0.24±0.01; p<0.001). Collateral-dependent perfusion measured under conditions of maximal vasodilatation 1 week after FAL using fluorescent microspheres was impaired in apoE-/- on WTD compared to WT mice (R/L leg ratio in WT 78±13 vs. apoE-/- 56±6; p<0.001) and was normalized by aleglitazar treatment. Neoangiogenesis was measured in-vivo by subcutaneously implanting discs covered with cell-impermeable filters. The vascularized area of the discs was quantified after 14 days by perfusion of the animals with space-filling fluorescent microspheres. Aleglitazar increased neoangiogenesis in WT mice by 178±18% compared to vehicle (p<0.05). Endothelium-dependent relaxation of aortic rings was impaired in apoE-/- mice on WTD for 6 weeks (relaxation to 52±5% of max. contraction) compared to WT animals (relaxation to 18±5% of max. contraction) (p<0.001). Aleglitazar treatment improved endothelial function (relaxation to 39±5% of max. contraction; p<0.05). In parallel, number and function of EPC were improved in mice. Studies in human EPC showed that 1) aleglitazar’s effects were mediated by both PPAR-α and -γ signalling and Akt and 2) migration and colony forming units were up-regulated by aleglitazar in cultivated EPC from CAD patients. Conclusion: The study provides evidence for beneficial effects of the dual PPAR-α/γ agonist aleglitazar on vascular function in addition to or mediated by its metabolic actions.

Although the biological mechanisms underlying the beneficial effects of vitamin B6 on cardiovascular disease (CVD) have been reported on, epidemiological studies have yielded controversial results, and data on the Korean population are limited. This study examined the association between dietary vitamin B6 intake and CVD incidence in Koreans. A total of 9142 participants of the Korean Genome and Epidemiology Study, aged 40–69 years, who did not have CVD or cancer at the baseline were included in the analysis. Dietary data were assessed using a validated semi-quantitative food frequency questionnaire. CVD incidence was assessed using biennial questionnaires and confirmed through repeated personal interviews. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazard regression models. After multivariate adjustment, a higher vitamin B6 intake was significantly associated with a decreased CVD risk in men (HR: 0.44; 95% CI: 0.25–0.78); no such association was observed in women. Dose-response analysis confirmed the presence of inverse linearity between vitamin B6 intake and CVD incidence in men (p for nonlinearity = 0.3). A higher dietary intake level of vitamin B6 was associated with a reduced CVD risk in Korean men. These observations require further verification in other populations.

Background: Punica granatum L. is an infructescence native of occidental Asia and Mediterranean Europe, popularly referred to as pomegranate. It has been used in ethnomedicine for several applications, including the treatment of obesity, inflammation, diabetes, and the regulation of blood lipid parameters. Thus, pomegranate has been linked to the treatment of cardiovascular diseases that have endothelial dysfunction as a common factor acting mainly against oxidative stress due to its high polyphenol content. Its biocomponents have antihypertensive, antiatherogenic, antihyperglycemic, and anti-inflammatory properties, which promote cardiovascular protection through the improvement of endothelial function. Methods: Different electronic databases were searched in a non-systematic way to uncover the literature of interest. Conclusion: This review article presents updated information on the role of pomegranate in the context of endothelial dysfunction and cardiovascular diseases. We have shown that pomegranate, or rather its components (e.g., tannins, flavonoids, phytoestrogens, anthocyanins, alkaloids, etc.), have beneficial effects on the cardiovascular system, improving parameters such as oxidative stress and the enzymatic antioxidant system, reducing reactive oxygen species formation and acting in an anti-inflammatory way. Thus, this review may contribute to a better understanding of pomegranate's beneficial actions on endothelial function and possibly to the development of strategies associated with conventional treatments of cardiovascular diseases.

To test the hypothesis that high-intensity swim training improves cardiovascular health status in sedentary premenopausal women with mild hypertension, sixty-two women were randomized into high-intensity (n=21; HIT), moderate-intensity (n=21; MOD), and control groups (n=20; CON). HIT performed 6–10 × 30 s all-out swimming interspersed by 2 min recovery and MOD swam continuously for 1 h at moderate intensity for a 15-week period completing in total44±1and43±1sessions, respectively. In CON, all measured variables were similar before and after the intervention period. Systolic BP decreased (P<0.05) by6±1and4±1 mmHg in HIT and MOD; respectively. Resting heart rate declined (P<0.05) by5±1bpm both in HIT and MOD, fat mass decreased (P<0.05) by1.1±0.2and2.2±0.3 kg, respectively, while the blood lipid profile was unaltered. In HIT and MOD, performance improved (P<0.05) for a maximal 10 min swim (13±3% and22±3%), interval swimming (23±3% and8±3%), and Yo-Yo IE1 running performance (58±5% and45±4%). In conclusion, high-intensity intermittent swimming is an effective training strategy to improve cardiovascular health and physical performance in sedentary women with mild hypertension. Adaptations are similar with high- and moderate-intensity training, despite markedly less total time spent and distance covered in the high-intensity group.

Endothelial dysfunction is an early abnormality in the process of atherosclerosis and cardiovascular disease and has been associated with worse clinical outcome. Cardiac rehabilitation (CR) has been reported to be helpful to reduce cardiovascular events in various types of cardiac disease, but the mechanisms of its beneficial effects remain only partially known. In this article, we review the studies that assessed the effect of CR on endothelial function in patients with various cardiac conditions. Available data show that CR significantly improves impaired endothelial function in these patients, which may contribute to the beneficial effects of CR on clinical outcome.
