Analysis of local hemodynamics in central and peripheral arteries
… system, the propagation of waves in arteries has to be investigated, since they carry information which can be used for the prevention and diagnosis of cardiovascular diseases. The main goal of this thesis is to improve the understanding of wave propagation in central and peripheral …

Flow characteristics and wall shear stresses in bifurcated peripheral arteries
Peripheral artery disease (PAD) is further complicated by co-morbidities like diabetes, hypertension and anemia. Previous studies on coronary and carotid arteries indicate that bifurcation at the arteries has an effect in the blood flow. When plaque develops at the bifurcation, it affects the …

Resistance to Apoptosis in Smooth Muscle Cells and Stent-Induced Stenosis in Coronary and Peripheral Arteries
… of lesion development. It was hypothesized that arteries from alternate embryological origins react differently with regards to the development of in-stent stenosis and that vascular smooth muscle cells derived from different arteries are unique with regards to their apoptotic responses. To test …

Diagnostik der Becken-Bein-Gefässe mittels kontrastmittelangehobener 3D-MR-Angiographie
… 3D-MR-Angiography for the assessment of peripheral arteries from the abdominal aorta to the lower leg arteries. METHODS: 3D-MRA was performed in 62 patients, using a Gd-DTPA enhanced T1 weighted 3D gradient-echo sequence (FFE). Results for 23 vascular segments from the abdominal aorta to …

The Impact of Outward Remodeling on Vasodilation in Skeletal Muscle Resistance Arteries
<p>Peripheral arterial occlusive disease (PAOD) is an ischemic disease characterized by narrowing of the peripheral arteries due to the accumulation of atherosclerotic plaque in the inner lining of the vessels, which disrupts blood flow to downstream tissues. Blood can be redirected into collateral …

The Cardiovascular Effect of GLP-1 in Humans
… I hypothesized that this effect is mediated by peripheral or coronary vasodilatation. A comprehensive assessment of the haemodynamic effects of GLP-1 in humans was made, in peripheral arteries using plethysmography, and in coronary arteries using invasive pressure and flow assessments during …

Centrinių ir periferinių arterijų struktūrinių ir funkcinių pakitimų ypatumai sergant metaboliniu sindromu /
… and structural changes in cardiovascular arteries and increase of the left ventricle myocardial mass index. The particularity of changes in different arterial stiffness indicators in patients with MS has not been determined yet in the literature, as well as prognostic value of MS when …

A novel footwear intervention to assist in the gait of patients with intermittent claudication
Peripheral arterial disease is characterised by blocking of the peripheral arteries. A common symptom is intermittent claudication, a cramping pain felt intermittently during activity such as walking. This is due to muscle oxygen demand surpassing the available supply and can significantly reduce …

Cardiovascular and metabolic control in obese children and adolescents
… in radial artery, increased vascular diameter in peripheral arteries and decreased pulse wave velocity compared to lean subjects. Obese children and adolescents also show cardiac autonomic dysfunction in terms of decreased baroreceptor sensitivity, decreased maximal exercise heart rate and greater …

Laminar and Transitional Flow disturbances in Diseased and Stented Arteries
… is dependent on the geometry and compliance of arteries, and pulsatility of blood flow. Understanding of such hemodynamic regulation in relation to atherosclerosis is of significant clinical importance in the prediction and progression of heart disease as well as design of prosthetic devices …

Application of magnetic resonance elastography to atherosclerosis
… Imaging protocol for in vivo MRE through the peripheral arteries of healthy volunteers and peripheral artery disease patients was developed. The presence of physiological motion and low signal to noise ratios made the vessel anatomy unidentifiable. The application of MRE to atherosclerotic …

Acceleration of Subtractive Non-contrast-enhanced Magnetic Resonance Angiography
… system, including the characteristics of arteries and veins, and the MR properties and flow characteristics of blood. These characteristics are the foundation of NCE-MRA technique development. Chapter 2 introduces commonly used diagnostic angiographic methods, particularly CE-MRA and …

Molecular imaging of spatio-temporal distribution of angiogenesis in hindlimb ischemia model and diabetic milieu
… of atherosclerotic occlusive disease of the peripheral arteries of diabetic patients, in conjunction with anatomic and functional microcirculatory impairments contribute to development of trophic ulcerations, infections and gangrene of the lower extremities, frequently requiring amputation of …

Metabolic profile and post-operative outcomes in contemporary patients with peripheral arterial disease and critical limb ischaemia
Background: Peripheral arterial disease (PAD) is an established occlusive disease of the peripheral arteries and is not uncommon in the elderly. Atherosclerosis accounts for 90% of the pathology. Only 15% of affected individuals become symptomatic. Most symptomatic individuals present with …
