  1. 1. Assessment of myocardial viability using magnetic resonance imaging

    Författare :Robert Jablonowski; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; myocardial infarction; hypertrophic cardiomyopathy; fibrosis; viability;

    Sammanfattning : Myocardial infarction (MI) following an acute coronary occlusion is a leading cause of morbidity and mortality. During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated. LÄS MER

  3. 2. Myocardial Scars on MRI : Their Prevalence and Possible Impact

    Författare :Charlotte Ebeling Barbier; Håkan Ahlström; Tomas Bjerner; Lars Johansson; Lars Lind; Kirsi Lauerma; Uppsala universitet; []
    Nyckelord :Radiology; magnetic resonance imaging; myocardial infarction; epidemiology; myocardial infarction; epidemiology; Radiologisk forskning;

    Sammanfattning : Myocardial infarction (MI) causes high morbidity and mortality worldwide and for effective prevention and treatment MIs have to be adequately detected.The existence of clinically unrecognized MIs (UMIs) has been known for the past hundred years, but an ultimate tool for their detection has not yet been found.

  4. 3. 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

  5. 4. Dysfunctional but viable myocardium - ischemic heart disease assessed by magnetic resonance imaging and single photon emission computed tomography

    Författare :Martin Ugander; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; medical instrumentation; Klinisk fysiologi; radiology; tomography; Clinical physics; non-invasive imaging; myocardial infarction; viability; Physiology; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : The assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. LÄS MER

  7. 5. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

    Författare :Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; transesophageal echocardiography; low-dose dobutamine; viability; coronary artery bypass; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Sammanfattning : Transesophageal echocardiography (TEE) has become a useful tool in monitoring the heart in patients during open-heart surgery. This study was undertaken to evaluate whether it is feasible to use TEE to assess left ventricular myocardial viability in anesthetized patients scheduled for coronary artery bypass grafting (CABG).
