1. 11. Biomarkers of fibrosis in heart failure and relations to left ventricular size, function and outcome

   Författare :Johan Löfsjögård; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Heart failure (HF) is a syndrome with impaired quality of life and higher mortality than most forms of cancer. The excessive accumulation of collagen in the myocardial extracellular matrix is called myocardial fibrosis, which is a reaction to myocardial stress, myocardial injury and a part of the remodeling process that alters the shape, size, and function of the heart.

3. 12. The right ventricle in volume or pressure overload : Insights from novel imaging techniques

   Författare :Aleksandra Trzebiatowska-Krzynska; Eva Swahn; Niels Erik Nielsen; Lars Wallby; Marcus Carlsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : This study is inspired by the gap in knowledge regarding the timing of cardiac surgery and interventions in adult patients with congenital heart disease. There are many parameters used assessing right ventricular function; however, most of them have pitfalls. LÄS MER

4. 13. New insights in the assessment of right ventricular function : an echocardiographic study

   Författare :Avin Calcutteea; Michael Y Henein; Per Lindqvist; Jan Engvall; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 14. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

   Författare :Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 15. Effects of ageing and training on the human heart

   Författare :Frederic Bouvier; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ageing; endurance training; exercise capacity; myocardial perfusion scintigraphy; ejection fraction; left ventricular end-diastolic volume; ventricular arrhythmias and heart rate variability;

   Sammanfattning : The aim of the present studies was to evaluate the effects of ageing and endurance training on the human heart. One hundred and twelve healthy subjects, athletes and non-athletes, between 20 and 80 years of age and two master athletes between 70 and 80 years of age with previous myocardial infarction were investigated.
