  2. 1. Cardiac effects of non-adrenergic inotropic drugs : clinical and experimental studies

    Author : Birger Axelsson; Michael Haney; Hans Tydén; Anil Gupta; Patrick Wouters; Sven-Erik Ricksten; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milrinone; levosimendan; vein graft flow; myocardial ischemia; protection; inotropy; diastole; Anaesthesiology; anestesiologi;

    Abstract : Background: Myocardial failure and dysfunction is not uncommon during critical illness and following cardiac surgery. For optimal treatment, a better understanding of the effects of inotropic drugs is needed. In this thesis, two non-adrenergic mediated inotropes, milrinone and levosimendan were studied in different models of myocardial dysfunction. READ MORE

  4. 2. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

    Author : Martin Fredholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; strain echocardiography; right heart catheterization; cardiac surgery; heart failure; levosimendan; milrinone; left ventricular function; right ventricular function; systole; diastole; preload; afterload; pacing; longitudinal function; ventricular dimensions; ventricular interdependence;

    Abstract : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.

  6. 4. Lung Emphysema & Cardiac Function

    Author : Kirsten Jörgensen; Göteborgs universitet; []
    Keywords : emphysema; hemodynamics; ventricular end-diastolic volumes; lung volume reduction; ventricular function; transoesophageal echocardiography; magnetic resonance imaging; diastole; simendan; hypertrophy;

    Abstract : Patients with severe lung emphysema have poor quality of life because of impaired lung function and reduced exercise tolerance. Concomitant heart disease in severe emphysema is well recognised. The prevailing view is that mainly the right side of the heart is involved, while the issue of left ventricular (LV) involvement is less studied. READ MORE

  7. 5. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

    Author : Toomas Kangro; Uppsala universitet; []
    Keywords : Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

    Abstract : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. READ MORE
