  1. 1. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography

    Författare :Kambiz Shahgaldi; Lars-Åke Brodin; Michael Haney; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Three-dimensional echocardiography; heart chambers; flow-volume loop; left ventricular ejection fraction; visualization; left ventricular stroke volume; left ventricular outflow tract; and single-heartbeat; Medical technology; Medicinsk teknik;

    Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER

  3. 2. Nitrates and Left Ventricular Dysfunction

    Författare :Erik Tingberg; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid peroxidation; malondialdehyde; peptide; brain natriuretic peptide; left ventricular dysfunction; nitrates; acute myocardial infarction; heart failure; atrial natriuretic; diuretics; echocardiography; haemodynamic measurements; neurohumoral activation; diastolic dysfunction; Cardiovascular system; Medicin människa och djur ; Medicine human and vertebrates ; Kardiovaskulära systemet; oxidative stress; isoprostanes;

    Sammanfattning : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. LÄS MER

  4. 3. Left ventricular dysfunction in critically ill patients

    Författare :Oscar Cavefors; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular dysfunction; Left ventricular diastolic dysfunction; hsTNT; NT-proBNP; Coronary angiography; Regional wall motion abnormalities; Takotsubo syndrome; Septic cardiomyopathy; MINOCA; Cardiac disease; Intensive care unit; Echocardiography;

    Sammanfattning : ABSTRACT Background: Cardiac dysfunction is common in Intensive Care Unit (ICU) patients and can contribute to multiorgan failure and death. Despite this, few studies have been performed on pathogenies, prevalence, diagnosis and impact on mortality in unselected ICU patients. LÄS MER

  5. 4. 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.

  7. 5. 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.
