  1. 21. Cardiovascular function and biomarkers in women with preeclampsia

    Författare :Rangeen Rafik Hamad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Preeclampsia; endothelial function; FMD; thrombin; microparticle; menstrual cycle; ventricular diastolic function; echocardiography; NT-pro-BNP; cystatin C; CRP; inflammation; hemostasis; Pentraxin 3; angiogenesis; pregnancy; follow-up;

    Sammanfattning : Background: Preeclampsia (PE) is a multisystem disorder peculiar to human pregnancy and characterized by the onset of hypertension and proteinuria after the 20th week of gestation. The pathophysiology of this disorder is still not clear. LÄS MER

  3. 22. Cardiac function and long-term volume load : Physiological investigations in endurance athletes and in patients operated on for aortic regurgitation

    Författare :Kristofer Hedman; Eva Nylander; Éva Tamás; Lars Brudin; Mats Börjesson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background and aims. The heart is a remarkably adaptable organ, continuously changing its output to match metabolic demands and haemodynamic load. But also in long-term settings, such as in chronic or repeated volume load, there are changes in cardiac dimensions and mass termed cardiac hypertrophy. LÄS MER

  4. 23. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

    Författare :Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. LÄS MER

  5. 24. Left atrial function in health and disease

    Författare :Mark Henein; Per Lindqvist; Stellan Mörner; Reidar Winter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrium; Doppler echocardiography; atrial interaction; atrial pressure;

    Sammanfattning : The Objectives of this thesis are:1) To study possible atrial interaction in patients with right and left ventricular outflow tract obstruction due to significant pulmonary (PS) and aortic valve stenosis (AS), respectively.2) To assess left atrial (LA) intrinsic myocardial function and its relationship to indirect measures of left ventricular (LV) filling pressures in patients with paroxysmal atrial fibrillation (PAF).

  7. 25. Annular dynamics of the human heart : novel echocardiographic approaches to assess ventricular function

    Författare :Carljohan Carlhäll; Neil B. Ingels Jr.; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The complex myocardial fiber architecture of the left ventricle (LV) enables long-axis motion (annular excursion), short-axis motion and also a small torsional deformation throughout the cardiac cycle. The contribution of the long-axis motion has proven to be important in generating ventricular filling and emptying, and the analysis of annular excursion has become a well established diagnostic tool for the assessment of ventricular function.
