1. 1. Post Cardiac Arrest Care : Evaluation of prognostic tools, Patient outcomes and Relatives’ experiences at 6 months after the event

   Författare :Ewa Wallin; Sten Rubertsson; Marja-Leena Kristofferzon; Silvana Naredi; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac arrest; hypothermia; neurological outcome; cerebral oxygenation; MRI; relatives; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The overall aim of the present thesis was to study post-resuscitation care of cardiac arrest (CA) patients treated with target temperature management 33°C with a focus on evaluation of two prognostic tools: variations in cerebral venous saturation and acute magnetic resonance imaging (MRI) findings on the brain post-CA. An additional aim was to investigate patients’ neurological outcome and relatives’ experiences 6 months after the event. LÄS MER

3. 2. Development and Implementation of Cardiac Event Detectors in Digital CMOS

   Författare :Joachim Rodrigues; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Elektronik och elektroteknik; Electronics and Electrical technology; event detection; cardiac pacemaker; sleep- transistors; low-power; ASIC; Neural Networks; Electrogram; Signalbehandling; Wavelets;

   Sammanfattning : This doctoral dissertation presents the development and digital hardware realization of cardiac event detectors. Implantable medical appliances, as the cardiac pacemaker, have progressed from a life sustaining device to a device that considerably improves life quality for all ages. LÄS MER

4. 3. Neurological consequences of cardiac arrest

   Författare :Hans Rosén; Göteborgs universitet; []
   Nyckelord :cardiac arrest; prognosis; S-100; NSE; Neurofilament light protein; FIM; BNIS;

   Sammanfattning : An out-of-hospital cardiac arrest is a life-threatening event with very high early mortality. More than 50% of the patients who reach the emergency ward die, showing clinical signs of brain damage during the first weeks after admission. Survivors may suffer from post-ischemic encephalopathy, which influences their future lives. LÄS MER

5. 4. Cardiac Long-Axis Function. Experimental and Clinical Aspects

   Författare :Jonathan Berg; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; acute myocardal infarct; magnetic resonance imaging MRI ; pressure-volume loops; hypothermia; atrioventricular plane displacement; global longitudinal strain; Survival analyses;

   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

7. 5. Stroke during cardiac surgery : risk factors, mechanisms and survival effects

   Författare :Magnus Hedberg; Karl Gunnar Engström; Patrik Boivie; Jan van der Linden; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; cardiac surgery; adult; risk factors; mortality; embolism; aortic cross-clamp; aortic cannulation; Thoracic surgery; Thoraxkirurgi; kirurgi; särskilt thoraxkirurgi; Thoracic and Cardivascular Suregery;

   Sammanfattning : Introduction: Neurological complications and stroke in association with cardiac surgery is a serious problem. The stroke event can occur during surgery (early stroke) or in the postoperative period with a symptom free interval (delayed stroke). LÄS MER
