  1. 6. Heart rate variability and vascular function in healthy subjects and in patients with insulindependent (Type 1) diabetes mellitus

    Författare :Kerstin Jensen-Urstad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :atherosclerosis; autonomic nervous system; blood-glucose control; Holter ECG; heart rate variability; insulin-dependent diabetes mellitus; population-study; ultrasound; vascular endothelium.;

    Sammanfattning : The incidence of atherosclerosis parallels the decreasing function of the autonomic nervous system. Both atherosclerosis and autonomic dysfunction are common in patients with diabetes mellitus. LÄS MER

  3. 7. Importance of cardiac reserve for evaluation and prediction of cardiac function and morbidity assessed by low-dose dobutamine stress echocardiography

    Författare :Margareta Scharin Täng; Göteborgs universitet; []
    Nyckelord :Stress echocardiography; Heart failure; Beta-1-adrenoceptor; Cardiac reserve;

    Sammanfattning : This thesis aimed to evaluate the cardiac reserves capacity to be used to predict treatment effects, sub clinical heart disease and to evaluate b1-adrenoceptor (AR) gene polymorphism (Ser49Gly). Studies were performed in patients with dilated cardiomyopathy, in rats (young, healthy, diabetic and hypertensive), in mice (immunized against the ?1AR) and in heart-transplanted patients. LÄS MER

  4. 8. Effects of physical activity and gravitational stress on cardiovascular control

    Författare :Patrik Sundblad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :leg exercise; posture; blood pressure; heart rate; cardiovascular model; heart function; stroke volume; tilting; orthostasis; simulated weightlessness; long-term hypokinesia;

    Sammanfattning : The long-term goal of the present work was to characterize the responses to gravitational challenges in exercising humans after long-term head-down-tilt bedrest (HDT). HDT is a simulation of weightlessness with respect to effects on the systemic circulation, and previous studies in resting men have suggested that impairments of arterial baroreflexes contribute to the orthostatic intolerance seen after HDT and spaceflight.

  5. 9. Psychomotor and cardiorespiratory functions during inert gas sedation

    Författare :Anders Östlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :arterial baroreflex; heart rate; gas density; hyperbaric bradycardia; inert gas; inspiratory loading; narcosis; nitrous oxide; sedation; ventilation;

    Sammanfattning : Relative hypoventilation and bradycardia are commonly observed in both resting and exercising divers. Divers are exposed to a complex environment where there are increases of hydrostatic pressure, gas density and partial pressure of sedating inert gas. LÄS MER

  7. 10. Risk assessment in patients with acute myocardial infarction treated with thrombolysis

    Författare :Bassem Abdel Samad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :echocardiography; exercise stress test; heart rate variability; Holter recording; low-dose dobutamine echocardiography; myocardial infarction; myocardial perfusion scintigraphy; myocardial viability; prognosis; thrombolysis.;

    Sammanfattning : Risk stratification in patients with acute myocardial infarction is essential for guiding the clinical decision concerning management. Thrombolytic therapy and other new management policies have led to a significant reduction in mortality from myocardial infarction. LÄS MER
