1. Management of patients treated with left ventricular assist devices : A clinical and experimental study
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
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
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
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. LÄS MER
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
