1. 16. Lung Emphysema & Cardiac Function

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

   Sammanfattning : 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. LÄS MER

3. 17. 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

4. 18. Echocardiographic measurements of the heart : with focus on the right ventricle

   Författare :Karin Loiske; Kent Emilsson; Allan Sirsjö; Jan Engvall; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; heart; right ventricle; right ventricular outflow tract 1; isovolumetric relaxation time; maximal early diastolic relaxation velocity; takotsubo cardiomyopathy; long-axis function; MEDICINE; MEDICIN; Clinical physiology; Klinisk fysiologi; Biomedicin; Biomedicine;

   Sammanfattning : Echocardiography is a well established technique when evaluating the size and function of the heart. One of the most common ways to measure the size of the right ventricle (RV) is to measure the RV outflow tract 1(RVOT1). Several ways to measure RVOT1 are described in the literature. LÄS MER

5. 19. Cardiac function in experimental septic and non-septic conditions with special reference to the endothelin system

   Författare :David Konrad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :sepsis; cardiac; endothelin; endotoxin; levosimendan; contractility; diastolic; LVPVR.;

   Sammanfattning : Myocardial depression in sepsis has been intensely investigated for the past 30 years and still poses a considerable issue in the intensive care units. Both systolic and diastolic dysfunction is implicated, correlating with severity of illness and mortality The importance of the endothelin (ET) system in normal physiology has been extensively studied.

7. 20. Transoesophageal and transthoracic recordings of mitral annulus motion

   Författare :Bo Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Left ventricular function; echocardiography; M-mode; tissue Doppler; mitral annulus systolic and diastolic velocities;

   Sammanfattning : Maximal systolic and diastolic velocities recorded from four sites of the mitral annulus motion (MAM) reflect left ventricular (LV) performance. This thesis focus on factors influencing M-mode derived velocities in healthy children and adults and reference values are proposed. LÄS MER
