  1. 21. 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

  3. 22. 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.

  4. 23. Noninvasive Evaluation of Myocardial Ischemia and Left Ventricular Function

    Författare :Eva Maret; Jan Ohlsson; Eva Nylander; Anders Waldenström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function.Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia.

  5. 24. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography

    Författare :Petri Gudmundsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

    Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER

  7. 25. Implantable devices in heart failure : studies on biventricular pacing and continuous hemodynamic monitoring

    Författare :Frieder Braunschweig; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Implantable devices; congestive heart failure; biventricular pacing; hemodynamic monitoring; ambulatory; hospitalizations; positron emission tomography; stress; blood flow; loop diuretics; natriuretic peptides; hemodynamics.;

    Sammanfattning : Chronic heart failure is a highly symptomatic syndrome associated with increasing prevalence, frequent hospital admissions and high treatment costs. Despite recent advances in drug therapy, morbidity and mortality are still high. LÄS MER
