2. 1. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

   Author : Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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).

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

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

   Abstract : 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.

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

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

   Abstract : 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. READ MORE

6. 4. Takotsubo stress cardiomyopathy and different types of stress

   Author : Olov Collste; Karolinska Institutet; Karolinska Institutet; []
   Keywords : takotsubo stress cardiomyopathy;

   Abstract : Myocardial infarction with normal coronary angiography (MINCA) is an important subgroup of myocardial infarction for which the prevalence, underlying pathophysiology, prognosis and optimal management are still largely unknown. Interest in and awareness of MINCA has increased in recent years due to the frequent use of coronary angiography, the description of Takotsubo stress cardiomyopathy (TSC) and new sensitive troponin assays.

7. 5. Doppler tissue imaging in ST-elevation myocardial infarction

   Author : Nils Witt; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Highly available, noninvasive and cost-effective, echocardiography remains a keystone in the evaluation of patients with coronary artery disease (CAD). Echocardiographic assessment of cardiac function at rest and during dobutamine stress has direct clinical implications. READ MORE
