Introduction: Cardiovascular disease (CVD) remains the number one cause of mortality in the western world. Carotid intimal media thickness (carotid IMT) is a safe and reliable predictor of future CVD risk. Hypothesis: The study aims to assess the hypothesis that lifestyle factors impact carotid IMT, and determine which nutrition and fitness risk factors best predict mean carotid IMT scores. Methods: A prospective cross-sectional analysis of 592 men and women undergoing health and cardiovascular risk screening. This study reflects the first visit of these subjects, age 23 to 65 (mean = 48.2), who are followed longitudinally and who were participants at a “wellness” oriented program for patients who are generally well-educated and mostly in good health. Measurements were made of fitness using VO2max stress testing and push-up and sit-up scores following the American College of Sports Medicine testing protocols, diet intake using a 3-day dietary intake survey and computerized analyses. Mean carotid IMT scores were obtained using high resolution B-mode ultrasonography of the common carotid arteries. Each subject had ≥10 images collected from the far wall of the right and left distal 1 cm of the common carotid arteries at end diastole. The carotid intimal thickness was measured as a continuous variable, using both multivariate linear and bivariate linear regression. Multivariate analyses adjusted for potential confounders using multiple linear regression and included measures of body composition, blood pressure, fasting lipid and glucose levels, and statin use. Results: Multivariate analyses show that higher mean carotid IMT values are associated with increasing age (p<0.0001), male gender (p<.0.0001), lower aerobic capacity (p=0.0045), lower intake of fish (p=0.05), and lower intake of zinc (p=0.0002). Bivariate analyses controlling for age and gender, with and without statin use, showed higher mean carotid IMT scores were statistically associated with lower levels of aerobic fitness, (p = 0.0007), lower intake of fiber (p=0.02) and lower intake of magnesium (p=0.019). Intake of protein, carbohydrate, and fat as percent of calories; as well as intake of saturated fat, sodium, calcium, potassium, and vitamin K; measures of strength (assessed with push-up and sit-up testing); and self-reported exercise minutes per week were not associated with mean carotid IMT scores. Conclusions: In this database, aerobic fitness and dietary intake of fiber, fish, magnesium, and zinc are associated with lower carotid IMT scores. Further studies are warranted to explore the impact of emerging lifestyle factors on cardiovascular risk and clinical outcomes.

The blood flow in arteries affects both the biology of the vessels and the development of atherosclerosis. The flow is three dimensional, unsteady, and difficult to measure or to model computationally. We have used phase-shift-based magnetic resonance angiography to image and measure the flow in the common carotid arteries of a healthy human subject. There was curvature of the vessels and thin-slice dynamic flow imaging showed evidence of the presence of secondary motions. Flexing the cervical spine straightened the vessels and reduced the asymmetry of the flow.

Aim. To study changes in structural and functional features of the common carotid arteries and central hemodynamic parameters under the influence of fosinopril at hypertensive patients depending on achieving target blood pressure.Material and methods. The study included 116 patients with essential hypertension. All patients underwent a general clinical study, an ultrasound scan of the common carotid arteries (CCA ) with the assessment of the structure and intravascular blood flow, and echocardiography with the definition of the parameters of central hemodynamic and intravascular, ambulatory blood pressure monitoring (ABPM) before the study and after 24 weeks of antihypertensive therapy angiotensin - converting enzyme fosinopril. Two groups of patients: the first group consisted of 74 people with the achievement of the targets of blood pressure (BP), the second 42 people who have not been achieved target BP levels.Results. In the first group there was a statistically significant decrease in the proportion of peripheral resistance, increased systolic index, distensibility coefficient of the common carotid arteries peak flow velocity. In the second group specific peripheral resistance was significantly increased, the thickness of the intima-media increased, decreased peak flow velocity.Conclusion. Effectiveness depends on fosinopril initial state total peripheral resistance, cardiac output, structural and functional features elastic arteries.

Cerebral ischemia causes tissue death owing to occlusion of the cerebral blood vessels, and cerebral ischemia activates mitogen-activated protein kinase (MAPK) and induces secretion of pro-inflammatory cytokines. Adenosine A2A receptor agonist, polydeoxyribonucleotide (PDRN), suppresses the secretion of pro-inflammatory cytokines and exhibits anti-inflammatory effect. In the current study, the therapeutic effect of PDRN on cerebral ischemia was evaluated using gerbils. For the induction of cerebral ischemia, the common carotid arteries were exposed, and then aneurysm clips were used to occlude the common carotid arteries bilaterally for 7 minutes. In the PDRN-treated groups, the gerbils were injected intraperitoneally with 0.3 mL of saline containing 8 mg/kg PDRN, per a day for 7 days following cerebral ischemia induction. In order to confirm the participation of the adenosine A2A receptor in the effects mediated by PDRN, 8 mg/kg 7-dimethyl-1-propargylxanthine (DMPX), adenosine A2A receptor antagonist, was treated with PDRN. In the current study, induction of ischemia enhanced the levels of pro-inflammatory cytokines and increased phosphorylation of MAPK signaling factors in the hippocampus and basolateral amygdala. However, treatment with PDRN ameliorated short-term memory impairment by suppressing the production of pro-inflammatory cytokines and inactivation of MAPK signaling factors in cerebral ischemia. Furthermore, PDRN treatment enhanced the concentration of cyclic adenosine-3,5’-monophosphate (cAMP) as well as phosphorylation of cAMP response element-binding protein (p-CREB). Co-treatment of DMPX and PDRN attenuated the therapeutic effect of PDRN on cerebral ischemia. Based on these findings, PDRN may be developed as the primary treatment in cerebral ischemia.
