  2. 1. In the hands of ohm : hemodynamic aspects in pulmonary hypertension

    Author : Erik Tossavainen; Per Lindqvist; Michael Henein; Stefan Söderberg; Peter Eriksson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

    Abstract : Congestive heart failure (CHF) is one of the most challenging diseases in terms of health care demand and mortality, in the western world. Despite major breakthroughs in the fields of diagnosis and treatment over the three last decades, the management of CHF still remains challenging. READ MORE

  4. 2. Inhibition of 11 ß-HSD. Hemodynamic and hormonal response induced by liquorice

    Author : Helga A Sigurjónsdóttir; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11 ß-hydroxysteroid dehydrogenase; glycyrrhetinic acid; liquorice; hypertension; gender; androgen hormones;

    Abstract : Introduction: The enzyme 11 ß-hydroxysteroid-dehydrogenas (11 ß-HSD) type 2 that converts the active hormone cortisol to the inactive cortisone is inhibited by glycyrrhetinic acid (GA), the active substance in liquorice. This leads to hypertension, hypokalaemia and sodium- and fluid retention, the syndrome of pseudo-hyperaldosteronism. READ MORE

  5. 3. Sleep disordered breathing and hemodynamic function

    Author : Ludger Grote; Göteborgs universitet; []
    Keywords : sleep apnea; hypertension; blood pressure; vascular function; exercise; arousal;

    Abstract : This thesis addresses the association between sleep disordered breathing (SDB) and hemodynamic function. A cross sectional study in a sleep laboratory cohort (n=1190) demonstrated a dose-response relationship between the severity of SDB, expressed as respiratory disturbance index (RDI), and office blood pressure, heart rate, and the risk of hypertension.

  6. 4. Hemodynamic aspects of biventricular pacing in heart failure

    Author : Marcus Ståhlberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Heart failure; biventricular pacing; hemodynamic monitoring; heart rate; cardiac output;

    Abstract : Background and aims: Biventricular pacing or cardiac resynchronization therapy (CRT) is an established treatment option for selected heart failure (HF) patients. We aimed at evaluating acute and longer-term hemodynamic effects of different pacemaker programmings in CRT patients. READ MORE

  7. 5. Physiological aspects on intracardiac blood flow

    Author : Per Arvidsson; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Abstract : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.
