1. Nitrates and Left Ventricular Dysfunction
Sammanfattning : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. LÄS MER
2. Haemodynamic and ventilatory effects of laparoscopic surgery
Sammanfattning : Background: It has been shown repeatedly that the establishment of pneumoperitoneum (PP) is associated with increased cardiac filling pressures, as well as increased blood pressure and systemic vascular resistance. Patients without heart or lung disease can compensate for these effects of PP, but cardiopulmonary compromised patients may develop cardiac failure during PP. LÄS MER
3. Ultrasonic Methods for 2D Arterial Wall Movement Measurements
Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER
4. Noninvasive haemodynamic evaluation of aortic valve prostheses : Doppler echocardiographic studies at rest and during exercise
Sammanfattning : The present series of investigations was designed to supply information on in vivo pressure-flow relationships and to analyse the incidence of regurgitation in different heart valve prostheses in the aortic position. Patients and methods: The study population comprised 185 patients with mechanical Björk-Shiley Monostrut prostheses, 54 patients with Biocor stented porcine bioprostheses, 50 patients with extended Biocor stentless bioprostheses and 59 patients with cryopreserved aortic homografts.

5. Surgically corrected univentricular hearts. Anatomical, haemodynamic and functional status at a long-term follow-up
Sammanfattning : The Fontan operation and its modifications are applied to a large spectrum of congenital heart defectswith univentricular physiology. The Fontan circulation is characterised by a reduced, non-pulsatilepulmonary blood flow and the elevated central venous pressure is the main driving force for thepulmonary blood flow. LÄS MER
