  1. 11. Strain echocardiography in the critically ill patient : Studies in patients with septic shock and subarachnoid haemorrhage

    Författare :Keti Dalla; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Strain echocardiography in ICU patients; Left ventricle; Right ventricle; Septic shock; Subarachnoid haemorrhage; Norepinephrine;

    Sammanfattning : In this thesis, strain echocardiography by two-dimensional speckle tracking imaging (2D-STI), was used for the evaluation of left ventricular (LV) and right ventricular (RV) function in critically ill patients with septic shock and subarachnoid haemorrhage. The aims were to: 1) investigate the value of strain echocardiography for the early detection of LV and RV dysfunction not diagnosed with conventional echocardiography in severe sepsis and septic shock, 2) to study the effects of norepinephrine on RV systolic function and pulmonary haemodynamics in patients with norepinephrine-dependent septic shock 3) evaluate the use of strain echocardiography for detection of myocardial injury in patients with subarachnoid haemorrhage (SAH) and 4) study the impact of general anaesthesia and positive pressure ventilation (PPV) on RV and LV myocardial longitudinal strain.

  3. 12. Complementary strategies to improve positive response and outcome in patients with advanced heart failure undergoing CRT therapy

    Författare :ZOLTAN BAKOS; Kardiologi; []
    Nyckelord :;

    Sammanfattning : AbstractCardiac resynchronization therapy (CRT) has improved quality of life and survival in select heart faillure patients, however 30-40% of patients do not show objective benefit from the treatment. At the same time there is little evidence about the long term effect of changes in medical treatment in these patients. LÄS MER

  4. 13. Arrhythmogenic right ventricular cardiomyopathy : Is it right?

    Författare :Meriam Åström Aneq; Eva Nylander; Jan Engvall; Maria Eriksson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart disease, where sudden cardiac death in young seemingly healthy persons may be the first symptom. There is a need for more sensitive and accurate diagnostic methods to detect signs of disease, at an early stage and in relatives of affected individuals. LÄS MER

  5. 14. Cardiovascular development of the preterm infant

    Författare :Ulf Schubert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The numbers of preterm births and cardiovascular deaths are increasing in most countries. The causes of both developments are multiple and apparently not related to each other. LÄS MER

  7. 15. 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).
