1. 1. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

   Författare :Toomas Kangro; Uppsala universitet; []
   Nyckelord :Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

   Sammanfattning : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. LÄS MER

3. 2. 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

4. 3. Left ventricular filling during coronary artery bypass grafting

   Författare :Sten Samuelsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Heart: surgery; coronary artery revascularization; ventricle; mitral valve Cardiopulmonary bypass Cardiac output Thermodilution Echocardiography: transesophageal; two-dimensional; Doppler Radionuclide ventriculographySten Samue;

   Sammanfattning : Left ventricular (LV) filling, determination of preload, right ventricular end-diastolic volumes, volume contributions during early (E) and atrial (A) phases of LV filling and mitral valve opening areas were studied in 75 patients scheduled for elective coronary artery bypass grafting (CABG). The purposes of the study were: (1) To evaluate changes in LV filling judged as peak velocity E/A ratios determined by Doppler transesophageal echocardiography during and in the early phase after CABG.

5. 4. Echocardiographic assessment and B-type natriuretic peptide for risk evaluation in acute coronary syndromes

   Författare :Anita Persson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute coronary syndromes; Dopplerechocardiography; BNP; mortality; NT-proBNP; mitral regurgitation; congestive heart failure; restrictive filling pattern;

   Sammanfattning : Acute coronary syndromes (ACS) is one of the most common causes of emergency medical care and the single most common cause of death in Sweden in both men and women. Despite a significant improvement in survival in the acute phase, the frequency of rehospitalization and death in subsequent years is unacceptably high. LÄS MER

7. 5. Myocardial electromechanical function in long QT syndrome

   Författare :Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; stress-echocardiography; left ventricular filling; mechanical dispersion; diastolic myocardial function; exercise; arrhythmia; electromechanical window; speckle-tracking echocardiography; myocardial relaxation sequence.; kardiologi; Cardiology; cardiovascular disease; hjärt- och kärlforskning;

   Sammanfattning : AIM: The aim of this thesis is to assess, in LQTS and according to genotype, the myocardial electromechanical (EM) function response to exercise, its relation to symptoms and its response to b-blocker therapy. To achieve this aim, we conducted 4 studies with the following specific objectives: i. LÄS MER
