1. 1. 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).

3. 2. Importance of cardiac reserve for evaluation and prediction of cardiac function and morbidity assessed by low-dose dobutamine stress echocardiography

   Författare :Margareta Scharin Täng; Göteborgs universitet; []
   Nyckelord :Stress echocardiography; Heart failure; Beta-1-adrenoceptor; Cardiac reserve;

   Sammanfattning : This thesis aimed to evaluate the cardiac reserves capacity to be used to predict treatment effects, sub clinical heart disease and to evaluate b1-adrenoceptor (AR) gene polymorphism (Ser49Gly). Studies were performed in patients with dilated cardiomyopathy, in rats (young, healthy, diabetic and hypertensive), in mice (immunized against the ?1AR) and in heart-transplanted patients. LÄS MER

4. 3. Acute myocardial infarction : early diagnosis and the prognostic value of ECG and echocardiography

   Författare :Josephine Muhrbeck; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Introduction: Acute myocardial infarction (AMI) is a main cause of death. Despite vast improvements in management and treatment strategies over the past decades, morbidity and mortality after an AMI remains high. LÄS MER

5. 4. Risk assessment in patients with acute myocardial infarction treated with thrombolysis

   Författare :Bassem Abdel Samad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :echocardiography; exercise stress test; heart rate variability; Holter recording; low-dose dobutamine echocardiography; myocardial infarction; myocardial perfusion scintigraphy; myocardial viability; prognosis; thrombolysis.;

   Sammanfattning : Risk stratification in patients with acute myocardial infarction is essential for guiding the clinical decision concerning management. Thrombolytic therapy and other new management policies have led to a significant reduction in mortality from myocardial infarction. LÄS MER

7. 5. Electromechanical effects and optimization modalities of cardiac resynchronization therapy

   Författare :Cinzia Valzania; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cardiac resynchronization therapy; coronary blood flow; dyssynchrony; echocardiography; exercise; heart failure; hemodynamics; intracardiac electrogram; intracardiac impedance; optimization;

   Sammanfattning : Background and aims: Heart failure is a major health care problem, with high morbidity and mortality rates. In recent years, cardiac resynchronization therapy (CRT) has become an established additive treatment for patients with advanced heart failure, left ventricular (LV) dysfunction, and wide QRS complex.
