2. 1. Atrial function and loading conditions in athletes

   Author : Flavio D'Ascenzi; Michael Henein; Sergio Mondillo; Roxy Senior; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; athlete s heart; training; exercise; speckle-tracking echocardiography; atrial strain; atrial deformation; Cardiology; kardiologi;

   Abstract : Intensive training is associated with hemodynamic changes that typically induce an enlargement of cardiac chamber. Despite LA dilatation in athletes has been interpreted as a benign adaptation, little evidence is available. READ MORE

4. 2. Left Ventricular Dynamics During Exercise in Endurance Athletes

   Author : Milena Sundstedt; Tommy Jonason; Egil Henriksen; Eva Nylander; Uppsala universitet; []
   Keywords : Physiology; athletes; exercise; left ventricular dynamics; stroke volume; mitral annular motion; Fysiologi;

   Abstract : Large quantities of data have described left ventricular adaptation to endurance training, but basic concepts on left ventricular performance during exercise remain controversial. In this thesis, we present the results of studies of left ventricular dynamics during exercise in 89 endurance-trained athletes. READ MORE

5. 3. Early Cardiovascular Changes of Familial Hypertrophic Cardiomyopathy in the Young

   Author : Eva Fernlund; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; A-ECG. SCD.; advanced ECG; CMR; Tissue Doppler; Echocardiography; Microcirculation; LaserDoppler; Athletes heart; HCM; hypertrophic cardiomyopathy; Familial hypertrophic cardiomyopathy;

   Abstract : Familial hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease, transmitted in an autosomal dominant fashion, i.e. 50% risk for transmission of the disease-causing mutation to each child of the affected family. READ MORE

6. 4. Pump Physiology in the Remodeled Heart

   Author : Björn Östenson; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac magnetic resonance; cardiac remodeling; exercise imaging; exercise physiology; regional contributions to stroke volume; feature-tracking strain; atrioventricular plane displacement; atrioventricular coupling; ventricular-arterial coupling; clinical physiology;

   Abstract : This thesis aimed to increase the understanding of pump physiology in the remodeled heart compared to normal pump physiology.Study I was a cross-sectional observatory study investigating the regional contributions to stroke volume in patients with heart failure prior to cardiac resynchronization therapy (CRT) and tested the hypothesis that this characterization of pumping could predict CRT response.

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

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

   Abstract : 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.
