1. 1. Distensibility in Arteries, Arterioles and Veins in Humans : Adaptation to Intermittent or Prolonged Change in Regional Intravascular Pressure

   Författare :Roger Kölegård; Ola Eiken; Toste Länne; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arterial stiffness; venous distensibility; venous flow characteristics; bedrest; pressure training; Physiology; Fysiologi;

   Sammanfattning : The present series of in vivo experiments in healthy subjects, were performed to investigate wall stiffness in peripheral vessels and how this modality adapts to iterative increments or sustained reductions in local intravascular pressures. Vascular stiffness was measured as changes in arterial and venous diameters, and in arterial flow, during graded increments in distending pressures in the vasculature of an arm or a lower leg.

3. 2. The Influence of Intrauterine Environment on Cardiovascular Development During Fetal Life

   Författare :Helena Gardiner; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduktion; sexualitet; andrology; reproduction; sexuality; Obstetrik; gynekologi; Obstetrics; gynaecology; arterial distensibility; twin-twin transfusion; Growth-restriction; Fetal; Cardiovascular Development; andrologi;

   Sammanfattning : Fetal growth restriction has been linked to later cardiovascular disease, possibly through reduced arterial distensibility in response to a suboptimal intrauterine environment. This thesis sought firstly to examine the relationship between fetal growth and haemodynamics and their effect on later cardiovascular function and secondly to examine the effects of differential volume loading on arterial distensibility in genetically identical monochorionic twins with twin-twin transfusion syndrome (TTTS) and to explore the effect that early treatment has on vascular development.

4. 3. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

   Författare :Toomas Kangro; Uppsala universitet; []
   Nyckelord :Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

   Sammanfattning : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. LÄS MER

5. 4. Aspects on wall properties of the brachial artery in man : with special reference to SLE and insulin-dependent diabetes mellitus

   Författare :Niclas Bjarnegård; Toste Länne; Reinhard Volkmann; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arterial wall; atherosclerotic; brachial artery BA ; type 1 diabetes; ulse wave velocity PWV ; pulse wave analysis PWA ; intima-media thickness IMT ; nitrate mediated dilatation NMD ; Diabetology; Diabetologi;

   Sammanfattning : The mechanical properties of the arterial wall are of great importance for blood pressure regulation and cardiac load. With increasing age, large arteries are affected by increased wall stiffness. LÄS MER

7. 5. Influence of genetics and mechanical properties on large arteries in man

   Författare :Rachel De Basso; Toste Länne; Martin Björck; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Arterial pathology is the major contributor to cardiovascular diseases and mortality. The mechanical properties of arteries are independent factors for cardiovascular disease and mortality, where genetics influence the structure of the arterial wall, which may result in change in arterial stiffness.
