1. 1. PET in Heart Failure - Methods and Applications

   Författare :Jens Sörensen; Göran Hedenstierna; Elisabeth Ståhle; Bengt Långström; Juhani Knuuti; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; congestive heart failure; myocardial ischemia; positron emission tomography; left ventricular dysfunction; tracer kinetic models; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : Positron Emission Tomography (PET) permits regional myocardial perfusion, fibrosis and oxidative metabolism to be non-invasively quantified with radioactive tracers such as [15O]-water and [1-11C]-acetate. PET is an established research tool in congestive heart failure (CHF), a major cause of morbidity and mortality. LÄS MER

3. 2. Myocardial metabolism in experimental infarction and heart failure

   Författare :Truls Råmunddal; Göteborgs universitet; []
   Nyckelord :Myocardial metabolism; Heart failure; Myocardial infarction; Lipotoxic heart disease; Apolipoprotein B; Arrhythmias; Cardiac reserve; Creatine metabolism;

   Sammanfattning : Abstract The heart is an organ heavily dependent on exogenous lipids for the oxidative production of adenosine-triphosphate (ATP) and therefore maintenance of normal cellular energy homeostasis. However, high energy flux organs such as the heart must closely match lipid import and utilization or otherwise lipids will accumulate in the cardiomyocytes. LÄS MER

4. 3. Management of patients treated with left ventricular assist devices : A clinical and experimental study

   Författare :Bengt Peterzén; Henrik Casimir-Ahn; Hans Ruthberg; Lars Wiklund; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postcardiotomy heart failure; perioperative monitoring; coronary artery bypass; heart-assist devices; heart failure; congestive; ventricular dysfunction; Thoracic surgery; Thoraxkirurgi;

   Sammanfattning : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. LÄS MER

5. 4. Angiotensin converting enzyme inhibition and aspirin in congestive heart failure

   Författare :Tord Juhlin; Kardiologiska klinikens forskargrupp; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical trial; ARBs; renal function; congestive heart failure; ischaemic heart disease; NSAIDs; ACE-inhibitors; aspirin; dose dependency; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : Angiotensin-converting enzyme (ACE) inhibitors act by decreasing production of angiotensin II and by potentiating the effects of bradykinin by inhibition of its breakdown. Bradykinin exerts part of its effects via vasodilating prostaglandins. Since the cyclooxygenase (COX)-inhibitors, e.g. LÄS MER

7. 5. Vascular Effects of P2 Receptors. Changes in Congestive Heart Failure

   Författare :Malin Malmsjö; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; congestive heart failure; pyrimidine; purine; P2 receptor; vasodilatation; vasoconstriction; hyperpolarisation; EDHF; NO; Vascular; endothelium; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : Extracellular nucleotides induce dilatation and constriction of blood vessels by activation of P2 receptors. In this thesis the vasomotor effects of P2 receptor activation were studied in the rat mesenteric artery, and their changes in congestive heart failure (CHF) were evaluated using in vitro pharmacology, electrophysiology and competitive RT-PCR.
