1. Cardioplegia and cardiac function : evaluated by left ventricular pressure-volume relations
Sammanfattning : Purpose: This thesis is focused on studies of blood cardioplegia in order to evaluate regimens of myocardial protection during cardiac surgery. To further bring down operative mortality and morbidity, in patients with acutely ischaemic hearts, an optimal peroperative myocardial management is essential. LÄS MER
2. Connecting CMR and Physiology : Expanding the capabilities of cardiovascular magnetic resonance in quantifying physiology
Sammanfattning : The assessment of cardiovascular physiology is crucial to facilitate clinical diagnostics, treatment, and research. Physiology and anatomy can be assessed noninvasively using cardiovascular magnetic resonance (CMR), a versatile and reliable medical imaging modality free from ionizing radiation. LÄS MER
3. Cardiac Long-Axis Function. Experimental and Clinical Aspects
Sammanfattning : This thesis includes both experimental and clinical projects. The experimental studies investigate pathophysiological aspects of ventricular longitudinal function and therapeutic hypothermia during acute myocardial infarction (AMI). LÄS MER
4. Respiratory mechanics during mechanical ventilation in health and in disease
Sammanfattning : The elastic pressure-volume (Pel-V) curve of the respiratory system can be used as a guide for improved ventilator management. It may indicate risks of lung damage associated with collapse or overdistension of lung units. LÄS MER
5. New approaches to monitoring of cardiac function
Sammanfattning : Left ventricular pumping performance may be described by intraventricular pressure and volume variables, usually presented as a pressure-volume plot. However, on-line monitoring of left ventricular pressure and volume with high temporal resolution requires the use of an invasive catheter technique such as, for example, the conductance catheter method.
