Study Description
Brief Summary:
The main focus of the project is to determine to what degree myocardial energy metabolism is linked to impaired function in human cardiomyocytes, whether exercise training and remote ischemic preconditioning can restore cardiomyocyte function and whether this is linked to improved mitochondrial and cell function.

Condition or disease Intervention/treatment
Myocardial Injury Behavioral: Exercise training Procedure: remote ischemic preconditioning
