Large Artery Stiffness: Genes and Pathways
Aortic stiffness underlies systolic hypertension, promotes heart failure and is associated with in- creased cardiovascular morbidity and mortality. It is regarded as a primary driver of left ventricular hypertrophy and aortic aneurysms and is linked to the pathogenesis of cognitive impairment, …

PULMONARY ARTERY STIFFNESS IN RACEHORSES AFFECTED BY EXERCISE-INDUCED PULMONARY HEMORRHAGE
… this thesis was to investigate whether pulmonary artery stiffness (PAS), a Doppler-derived index of pulmonary arterial elasticity, can be used as a practical, non-invasive indicator of pulmonary vascular involvement in Thoroughbred racehorses affected by EIPH. Several studies were conducted to …

Effect of Nebivolol and Lifestyle Modification on Large Artery Stiffness in Middle-Aged and Older Hypertensive Adults
… disease and clearly associated with arterial stiffness. Arterial stiffness generates higher afterloads and diminishes coronary perfusion thereby causing ventricular hypertrophy and ischemia. Importantly, arterial stiffness is an independent predictor of cardiovascular disease risk and …

Investigating the Effects of Markers of Biological Stress on the Association between Adverse Childhood Experiences and Central Artery Stiffness
… risk is through their association with central artery stiffness. Pathways linking ACEs to arterial stiffness have not yet been fully elucidated; however, increased biological stress has been postulated to play a critical role. Recently, two markers have emerged as being potentially useful …

The Effects of Weight Gain and Atorvastatin Treatment on Arterial Stiffness
… in the cardiothoracic region. Importantly, large artery stiffness is an independent predictor of cardiovascular events and mortality in both healthy and diseased populations. The results of several studies suggest that obesity, particularly visceral adiposity, is associated with the accelerated …

Inflammation and arterial stiffness
Arterial stiffness is one of the earliest detectable manifestations of adverse structural and functional changes within the vessel wall. It is well known that increased large artery stiffness independently predicts the cardiovascular risk in a variety of populations. The identification of …

Effects of Aerobic Exercise on Cognitive and Cerebrovascular Function in Hypertensive Adults
… a single bout of aerobic exercise on 1) arterial stiffness and cerebral hemodynamics and 2) cognitive function in middle-aged adults with controlled-hypertension and without hypertension. Vascular and cognitive measures were assessed pre and post 30-min of aerobic exercise at ≈55% maximal oxygen …

Racial differences in cardiovascular responses following an acute bout of aerobic exercise
… output, peripheral resistance and arterial stiffness measurements and 30 min, 60 min and 90 min after 45 min of treadmill exercise at 70% HRreserve. An acute bout of aerobic exercise increases DBP in young AA but not in CA. The underlying mechanism for the BP increases may be related to …

The effect of metformin on vascular function and AMP-activated protein kinase activation in Type 2 diabetes
… improves vascular endothelial function and large artery stiffness in patients with Type 2 diabetes. In parallel, the thesis examines if metformin exerts its beneficial effects in patients with Type 2 diabetes in association with altered AMPK activity in human adipose. Finally, the thesis …

Studies of vascular function in patients with heart failure and either preserved or reduced left ventricular systolic function
… combination of LV diastolic dysfunction, or ‘LV stiffness’, and large artery stiffness, when compared with normal subjects and patients with systemic hypertension. This implies that the interaction between the left ventricle and the vasculature is dysfunctional and a potential cause of HF-PSF. …

Pulmonary arterial pulse wave velocity measurement in horses
… velocity (PWV) provides a measure of arterial stiffness. This study aimed to develop a technique to determine PA-PWV in standing sedated horses, and secondarily to investigate a potential association between PA-PWV and the presence of fibro-calcified lesions in the PA of these animals. A dual …

Vascular and metabolic profile of 5-year sustained hypertensive versus normotensive black South Africans
… exists between hypertension and arterial stiffness. Whether the increased arterial stiffness seen in hypertensives are due to structural or functional adaptations in the vasculature is uncertain. Hypertension is more common in blacks and they have an increased arterial stiffness and higher …
