ClinicalTrials.gov Identifier:
NCT01308138
First received: February 2, 2011
Last updated: August 1, 2013

  Purpose

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.
