  1. 1. Vascular Dysfunction in Stroke and CADASIL

    Författare :Anna Stenborg; Lars Lind; Andreas Terent; Toste Länne; Uppsala universitet; []
    Nyckelord :Internal medicine; stroke; CADASIL; endothelium; vasodilation; Invärtesmedicin;

    Sammanfattning : Cerebrovascular disease (CVD) is strongly linked to hypertension and generally occurs later in life than coronary artery disease (CAD). Three quarters of the patients with symptomatic CVD are above 65 years of age. The risk factors are the same for CVD and CAD, but the relative importance of the vascular risk factors differs greatly.

  3. 2. Mental Stress and Endothelium-Dependent Vasodilation

    Författare :Kristina Johansson; Sverker Jern; Uppsala universitet; []
    Nyckelord :Medical sciences; Mental stress; endothelium; adrenoceptor blockade; catecholamine; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The endothelium plays an important part in blood flow regulation by producing the vasodilatory substance nitric oxide (NO). Various studies have shown that commonly accepted risk factors for coronary heart disease, such as hypertension, diabetes, hypercholesterolemia, smoking and mental stress impair endothelium-derived vasodilation by the NO-pathway.

  4. 3. Effects of triglycerides on the endothelium

    Författare :Pia Lundman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Atherosclerosis; coronary heart disease CHD ; endothelial function; vasodilation; nitric oxide NO ; hypertriglyceridaemia; triglycerides; free fatty acids; ADMA; cellular adhesion molecules; von Willebrand factor.;

    Sammanfattning : Hypertriglyceridaemia (HTG) is a risk factor for coronary heart disease (CHD), although the mechanisms behind the increased risk remain to be defined. It is unclear whether atherogenic or thrombogenic factors are involved, or a combination thereof the endothelium is important in maintaining normal vascular function and has a key role in atherogenesis.

  5. 4. 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

  7. 5. Treating vascular dysfunction in chronic kidney disease : intervention with vitamin D

    Författare :Kristina Lundwall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Chronic kidney disease (CKD) is common, affecting 10-15% of the population worldwide. It is currently recognised by both cardiologists and nephrologists as a strong risk factor for cardiovascular events and death. LÄS MER
