  1. 1. Takotsubo stress cardiomyopathy and different types of stress

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science and Education, Södersjukhuset

    Author : Olov Collste; Karolinska Institutet.; Karolinska Institutet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.

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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science and Education, Södersjukhuset

    Author : Margareta Scharin Täng; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.

  3. 3. The importance of long axis function -an echocardiographic study with respect to ageing, response to treatment, prediction of survival and effect of warm water immersion

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science and Education, Södersjukhuset

    Author : Bente Grüner Sveälv; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; Long axis function; Heart failure; Age; Dobutamine stress; Recover; Prognosis; Warm water immersion;

    Abstract : Echocardiographic M-mode measurement of atrioventricular plane displacement (AVPD) and determination of annular velocity with Tissue Doppler imaging (TDI) is a reliable method to gauge ventricular long axis function for quantification of myocardial contractility and relaxation. The aim of this thesis was to increase the understanding of the importance of long axis function with respect to ageing, response to pharmacological treatment, prediction of survival, and enhanced load condition caused by warm water immersion.

  4. 4. Cardiac electrophysiologic effects of mental stress

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine at Huddinge University Hospital

    Author : Per Insulander; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: Mental stress may trigger serious arrhythmias. Mental stress tests cause significant increases in heart rate, blood pressure and cardiac output. When beta-adrenergic inhibition is considered for secondary antiarrhythmic prophylaxis beta1 selective agents are often preferred because of less adverse reactions. READ MORE

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

    University dissertation from Malmö : Malmö University. Faculty of Health and Society

    Author : Petri Gudmundsson; Malmö University.; [2006]
    Keywords : Humanities Social Sciences; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

    Abstract : Echocardiography is an ideal clinical method for obtaining information about morphology and function of the heart. Echocardiography is more accessible, mobile and inexpensive compared to other imaging techniques and has become the perhaps most used diagnostic method in cardiology during recent years. READ MORE
