  1. 16. Insight into Coro-Carotid atherosclerotic disease in patients with acute coronary syndrome

    Author : Rafik B. Shenouda; Michael Y. Henein; Per Wester; Ana Djordjevic-Dikic; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute coronary syndrome; Agatston score; Atherosclerosis; Carotid calcifications; Carotid intima media thickness; Coronary calcifications; Echocardiography; Speckle tracking echocardiography; Strain; Strain rate; Tissue Doppler Imaging.; kardiologi; Cardiology;

    Abstract : Background: the arterial tree branches in different parts of human body are sharing the histological and physiological features. Atherosclerosis is a systemic arterial disease, hence is expected to affect to affect more than one arterial system with similar pathologic manifestations. READ MORE

  2. 17. No touch vein harvesting technique for coronary artery by-pass surgery : impact on patency rate, development of atheroscleosis, left ventricular function and clinical outcome during 16 years follow-up

    Author : Benny Johansson; Eva Swahn; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; coronary artery disease; coronary artery bypass grafting; vein grafts; no touch vein harvesting technique; intravascular ultrasound; echocardiography; clinical outcome; revascularization; outcome analysis; angina pectoris; myocardial infarction; mortality; randomized trial; Surgery; Kirurgi;

    Abstract : This thesis was based on a prospective randomized trial which was started in 1993 to compare the no touch (NT) with the conventional (C) technique of saphenous vein harvesting for CABG.In paper I, was demonstrated superior patency for the NT grafts at short-term (1.5 years; 95,6% vs 89%; p < 0,05) and long-term follow-up (8.

  3. 18. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

    Author : Martin Fredholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; strain echocardiography; right heart catheterization; cardiac surgery; heart failure; levosimendan; milrinone; left ventricular function; right ventricular function; systole; diastole; preload; afterload; pacing; longitudinal function; ventricular dimensions; ventricular interdependence;

    Abstract : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.

  4. 19. Aspects of regular long-term endurance exercise in adolescents, with focus on cardiac size and function, hormones, and the immune system

    Author : Louise Rundqvist; Maria Faresjö; Peter Blomstrand; Katarina Steding-Ehrenborg; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; endurance-trained; cardiac dimension; cardiac systolic function; cardiac diastolic function; growth hormone; immune response; echocardiography; biomarkers; cytokines; chemokines; insulin-like growth factor 1; type 1 diabetes-related autoantigen; proinsulin;

    Abstract : The long-term effects of starting high-intensity training at younger ages are largely unknown. The present studies focused on adolescents who had performed regular endurance exercise for several years at an elite level and compared those subjects with a control group of adolescents of similar age and sex who had not engaged in regular exercise.

  5. 20. Pulmonary hypertension. Clinical and pathophysiological studies

    Author : Nedim Selimovic; Göteborgs universitet; []
    Keywords : Pulmonary hypertension; Echocardiography; Right heart catheterisation; Pulmonary vascular resistance; Pulmonary function tests; Lung transplantation; Mortality on the waiting list; Vascular remodelling; Growth substances; Inflammation; Endothelin;

    Abstract : Pulmonary hypertension (PH) is a common abnormality, most often associated with various cardiopulmonary diseases. Pulmonary arterial hypertension (PAH) is a devastating pulmonary vascular disease characterised by the proliferation of endothelial, smooth-muscle cells and fibroblasts. READ MORE
