1. 6. Left Ventricular Function in Elderly Men : Metabolic, Hormonal, Genetic and Prognostic Implications

   Författare :Johan Ärnlöv; Anders Waldenström; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; echocardiography; heart failure; left ventricular function; genetics; mortality; insulin sensitivity; natriuretic peptides; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Geriatrics; geriatrik;

   Sammanfattning : Heart failure and left ventricular dysfunction are major causes of morbidity and mortality. In this thesis, metabolic, hormonal, genetic and prognostic aspects of echocardiographically determined left ventricular function were investigated in a fairly large longitudinal population-based study of men.

3. 7. Mechanical Circulatory Support in Left Ventricular Heart Failure

   Författare :Petter Schiller; Laila Hellgren; Anders Jönsson; Göran Dellgren; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical Circulatory Support; Left Ventricular Heart Failure; Left Ventricular Assist Device; Extracorporeal Membrane Oxygenation; ECMO; Thorax Surgery; Thoraxkirurgi;

   Sammanfattning : Short-term mechanical circulatory support (MCS) with ventricular assist devices or veno-arterial extracorporeal membrane oxygenation (VA ECMO) has become the standard treatment in patients with cardiogenic shock unresponsive to pharmacological treatment. However, the haemodynamic effects of these devices are not yet fully described, nor are their effects on ventricular function and myocardial recovery. LÄS MER

4. 8. Mechanical and histological disturbances in advanced heart failure and cardiac transplantation

   Författare :Matteo Cameli; Michael Henein; Guy Lloyd; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Advanced heart failure; heart transplantation; speckle tracking echocardiography; left ventricular function; right ventricular function; left ventricular fibrosis; left ventricular filling pressure; atrial strain; kariologi; Cariology;

   Sammanfattning : The general purpose of this thesis is to establish capability and accuracy of speckle tracking echocardiography (STE) in assessing left atrial (LA), left ventricular (LV) and right ventricular (RV) function and their correlation with myocardial fibrosis, filling pressure and clinical outcomes in advanced heart failure (HF) patients before and after heart transplantation (HT).I demonstrated that HT recipients had impaired LV twist dynamics in the form of reduced rotation twist angle and untwist rate but time to peak twist was not different from the age matched controls and other cardiac surgical patients.

5. 9. Surgical treatment in chronic aortic regurgitation : Timing, results, prognosis and left ventricular function

   Författare :Éva Tamás; Christian Olin; Eva Nylander; Mats Broqvist; Dan Lindblom; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic regurgitation; left ventricular function; exercise; physical capacity; echocardiography; Thoracic surgery; Thoraxkirurgi;

   Sammanfattning : Chronic aortic regurgitation (AR) of varying degree affects 13% of men and 8.5% of women. In persons with severe AR, the expected length of life and its quality are influenced. LÄS MER

7. 10. Pulsed Tissue Doppler and left ventricular filling in acute coronary syndromes

   Författare :Cecilia Wallentin Guron; Göteborgs universitet; []
   Nyckelord :Tissue Doppler; pulsed; regional timing; time interval; the E e filling index; E E; ; diastolic function; left ventricular filling pressure; right ventricular pressure; left atrial size.;

   Sammanfattning : Pulsed tissue Doppler is a new technique, which can investigate longitudinal left ventricular(LV) function, by measuring tissue velocities and timings. Patients with acute coronarysyndromes (ACS) frequently display a reduced longitudinal function. They also developglobal LV filling impairment. LÄS MER
