1. 1. 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

3. 2. Cardiac morphology and dynamics in Swedish elite orienteers : Evaluation of the right and left ventricle by two-dimensional and doppler echocardiography

   Författare :Egil Henriksen; Uppsala universitet; []
   Nyckelord :Medical sciences; Echocardiography; sudden unexpected death in young orienteers; right and left ventricular measurements; Doppler echocardiography in athletes; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Background. Between 1979 and 1992, 16 (15 males and 1 female) sudden unexpected cardiac deaths(SUCD) were reported in Swedish orienteers. Compared with previous reports in young athletes there was a 10- to 100-fold increase in the sudden death rate in young male elite orienteers during this period. The mean age was 25 years (range 18-32 years). LÄS MER

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

   Författare :Olov Collste; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :takotsubo stress cardiomyopathy;

   Sammanfattning : 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.

5. 4. 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

7. 5. Nitrates and Left Ventricular Dysfunction

   Författare :Erik Tingberg; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid peroxidation; malondialdehyde; peptide; brain natriuretic peptide; left ventricular dysfunction; nitrates; acute myocardial infarction; heart failure; atrial natriuretic; diuretics; echocardiography; haemodynamic measurements; neurohumoral activation; diastolic dysfunction; Cardiovascular system; Medicin människa och djur ; Medicine human and vertebrates ; Kardiovaskulära systemet; oxidative stress; isoprostanes;

   Sammanfattning : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. LÄS MER
