  1. 36. Imaging of coronary artery function and morphology in living mice - applications in atherosclerosis research

    Författare :Johannes Wikström; Göteborgs universitet; []
    Nyckelord :atherosclerosis; coronary artery; coronary flow velocity reserve; imaging; mouse; transthoracic Doppler echocardiography; ultrasound biomicroscopy;

    Sammanfattning : Atherosclerosis in the coronary arteries is the major reason for myocardial infarction and cardiovascular death. In the clinic, several imaging systems make it possible to study coronary artery function and morphology non-invasively, such as transthoracic Doppler echocardiography (TTDE). LÄS MER

  3. 37. Effects of physical exercise on coronary and peripheral vascular function. An integrative physiological study from rat to man

    Författare :Ulrika Hägg Samuelsson; Göteborgs universitet; []
    Nyckelord :exercise; endothelial function; coronary flow velocity reserve; colour Doppler echocardiography; oxidative stress; gene expression; stiffness; ultrasound biomicroscopy;

    Sammanfattning : Physical exercise is beneficial for the cardiovascular health. Numerous epidemiological studies reveal that physical activity reduces the risk of cardiovascular related death. Nevertheless, the underlying vessel wall specific physiological and molecular mechanisms still remain incompletely understood. LÄS MER

  4. 38. Aortic valvular flow : a clinical and experimental doppler echocardiographic study

    Författare :Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. LÄS MER

  5. 39. Detection and haemodilutive treatment of cerebral arterial vasospasm and delayed ischaemia after Aneurysmal Subarachnoid Haemorrhage

    Författare :Anders Ekelund; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral oxygen delivery.; cerebral blood flow; hypervolaemic haemodilution; isovolaemic haemodilution; transcranial cerebral oximetry; transcranial Doppler ultrasound; delayed ischaemic deficit; Aneurysmal subarachnoid haemorrhage; cerebral arterial vasospasm; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. LÄS MER

  7. 40. Assessment of venous insufficiency in patients with chronic venous leg ulcers.Venous hemodynamics before and after surgery

    Författare :Marie Magnusson; Göteborgs universitet; []
    Nyckelord :Colour Doppler Ultrasound; leg ulcer; varicose vein surgery; recurrent leg ulcers;

    Sammanfattning : Venous insufficiency in the legs is a common disease, which may be complicated by chronic leg ulcers in 1% among the population. Venous ulcer duration is often long compared to other aetiologies and for the patient it involves long periods of pain, discomfort and reduced quality of life. LÄS MER
