Vegard Malmo presented the poster “Aerobic interval training reduces the burden of atrial fibrillation”. The study shows that aerobic interval training for 12 weeks clearly reduces the burden of AF in symptomatic patients. It is followed by a significant improvement in VO2max, left atrial and ventricular function, cholesterol levels, and quality of life. Further studies are needed to evaluate the underlying mechanisms and the effect of exercise training for a longer period of time. The study was presented at the ESC Congress in Barcelona who was arranged August 30th to September 3d.
Aerobic interval exercise training two times per week gave significant improvements on the AHI index, self-reported sleepiness and maximal oxygen uptake in obese sleep apnea patients in a study from CERG shows. The patients had no change in body weight. Researcher Trine Karlsen presented the study at the congress. 30 obese men and women diagnosed with obstructive sleep apnea was randomized to 12 weeks of supervised aerobic interval training or control.

CERG was represented with 5 posters, and one invited oral presentation at the congress.
Researcher Charlotte Björk Ingul presented the poster “The effect of exercise on left ventricular twist in patients with type 2 diabetes and diastolic dysfunction”. The diastolic dysfunction improved on the patients, especially in the group who had preformed high intensity exercise training.
Erik Madssen presented the poster “Coronary atheroma regression and plaque characteristics after aerobic exercise assessed by intravascular ultrasound: a randomized controlled trial”. The combination of regular aerobic exercise and optimal medical treatment for 12 weeks induced a moderate regression of necrotic core and plaque burden in IVUS-defined coronary lesions. Changes in coronary artery plaque structure or morphology did not differ between patients undergoing High intensity interval training or continuous exercise with moderate intensity.
Researchers at CERG has been involved in a study presented by Joakim Lund at the congress with the poster “Diastolic function during exercise: effects of a 12 week high-intensity exercise program in patients with a recent myocardial infarction”. The study shows that left ventricular diastolic function during exercise is related to VO2peak. Interestingly, we found a trend towards an improved diastolic function after exercise training, even in a population with a relatively well preserved systolic and diastolic function. The results demonstrate the importance of obtaining measurements during exercise when evaluating the effects of an exercise training intervention.
Professor Øyvind Ellingsen presented preliminary results from the Smartex-HF study, a study of high intensity exercise in hear failure patients at the congress. The study is a collaboration between nine European hospitals and Universities, and one of the largest randomized exercise training studies having been performed.
