2. 1. Myocardial Perfusion and Function: Comparative assessment by ECG, SPECT and MRI

   Author : Eva Persson; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; medicinsk instrumentering; Physiology; radiologi; radiology; tomography; medical instrumentation; Klinisk fysiologi; Clinical physics; ST-segment deviation ; myocardial ischemia ; myocardial perfusion ; MRI; CMR; MPS; ECG; SPECT; Fysiologi; Cardiovascular system; myocardial function ; Kardiovaskulära systemet;

   Abstract : Evaluation of myocardial perfusion and function is important in management of patients with suspected or known coronary artery disease. This thesis focuses on the use of common diagnostic methods, myocardial perfusion single-photon emission computed tomography (MPS) and electrocardiography (ECG), to enhance and validate the diagnostic information.

4. 2. Electrocardiographic Imaging of Myocardial Ischemia, Infarction and Scar: Correlation with SPECT, MRI and Arrhythmias

   Author : David G Strauss; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Imaging; Arrhythmias; Ischemia; Infarction; Cardiomyopathy; SPECT; MRI;

   Abstract : This thesis focuses on the development and testing of electrocardiographic (ECG) methods to diagnose and characterize myocardial ischemia, infarction and fibrosis (scar). The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF).

5. 3. Clinically Unrecognized Myocardial Scars Detected by MRI

   Author : Raquel Espregueira Themudo; Tomas Bjerner; Andrew Arai; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unrecognized myocardial scars; myocardial infarction; epidemiology; magnetic resonance; computed topographic coronary angiography; exercise test; NT-proBNP; Radiology; Radiologi; Cardiology; Kardiologi;

   Abstract : A high percentage of unrecognized myocardial infarctions (UMIs) seen at delayed-enhanced magnetic resonance imaging (DE-MRI) are not detected by ECG. DE-MRI-detected UMIs are independent predictors of cardiovascular events in patients with coronary artery disease. READ MORE

6. 4. Myocardial Scars on MRI : Their Prevalence and Possible Impact

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

   Abstract : 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.

7. 5. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT

   Author : Erik Hedström; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Fysiologi; Physiology; humans; cardiac troponin T; creatine kinase isoenzyme MB; delayed contrast-enhanced magnetic resonance imaging; single photon emission computed tomography; myocardial perfusion; myocardial infarct size; myocardium at risk; duration of ischaemia; Kardiovaskulära systemet;

   Abstract : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. READ MORE
