  1. 6. Echocardiographic assessment of atrioventricular plane displacement, Clinical application in patients with coronary artery disease, atrial fibrillation and aortic stenosis

    Författare :Erik Rydberg; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prognosis; aortic stenosis; atrial fibrillation; AVPD; coronary artery disease;

    Sammanfattning : Left atrioventricular plane displacement (AVPD) has been shown to correlate well with left ventricular (LV) systolic function measured as ejection fraction (EF). AVPD has also been shown to be related to diastolic performance. LÄS MER

  2. 7. 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

    Författare :Bente Grüner Sveälv; Göteborgs universitet; []
    Nyckelord :Echocardiography; Long axis function; Heart failure; Age; Dobutamine stress; Recover; Prognosis; Warm water immersion;

    Sammanfattning : 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.

  3. 8. Nitric oxide in experimental pulmonary embolism

    Författare :Kristofer F Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination. LÄS MER

  4. 9. Myocardial Effects of Type 2 Diabetes, Co-morbidities, and Changing Loading Conditions : a Clinical Study by Tissue Velocity Echocardiography

    Författare :Satish C. Govind; Lars-Åke Brodin; Mohbubul Alam; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical technology; Medicinsk teknik;

    Sammanfattning : Ever since the validation of the tissue velocity echocardiography (TVE) technique more than a decade ago the modality has been used rather successfully in various clinical situations, at rest as well as during stress echocardiography. Hitherto, dobutamine stress echocardiography has been the hallmark of all forms of stress procedures, now with TVE, quantification of the longitudinal motions of the left ventricle shows far superiority, with improved sensitivity and specificity in the functional diagnosis of coronary artery disease.

  5. 10. New approaches to monitoring of cardiac function

    Författare :Emil Söderqvist; Lars-Åke Brodin; Michael Haney; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; left ventricle; pressure and volume; Medical engineering; Medicinsk teknik;

    Sammanfattning : Left ventricular pumping performance may be described by intraventricular pressure and volume variables, usually presented as a pressure-volume plot. However, on-line monitoring of left ventricular pressure and volume with high temporal resolution requires the use of an invasive catheter technique such as, for example, the conductance catheter method.
