  2. 1. New insights in the assessment of right ventricular function : an echocardiographic study

    Author : Avin Calcutteea; Michael Y Henein; Per Lindqvist; Jan Engvall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; echocardiography; right ventricle; ischaemic heart disease; pulmonary hypertension; aortic stenosis; aortic valve replacement; three dimensional echocardiography; speckle tracking echocardiography; Cardiology; kardiologi;

    Abstract : Background:  The right ventricle (RV) is multi-compartmental in orientation with a complex structural geometry. However, assessment of this part of the heart has remained an elusive clinical challenge. READ MORE

  4. 2. 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

  5. 3. Insights into the effect of myocardial revascularisation on electrical and mechanical cardiac function

    Author : Ihab Ramzy Guirguis; Michael Y Henein; Stellan Mörner; Reidar Winter; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial infarction; natriuretic peptides; echocardiography; ventricular function; atrial function; surgical revascularisation; speckle tracking echocardiography; Cardiology; kardiologi;

    Abstract : Background: Acute coronary syndrome is known for its effect on cardiac function and can lead to impaired segmental and even global myocardial function. Evidence exists that myocardial revascularisation whether pharmacological, interventional or surgical results in improvement of systolic and diastolic left ventricular (LV) function, particularly that of the long axis which represents the sub-endocardial function, known as the most sensitive layer to ischaemia.

  6. 4. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

    Author : Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

    Abstract : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. READ MORE

  7. 5. Myocardial electromechanical function in long QT syndrome

    Author : Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
