Coronary Artery Disease, Myocardial Infarction
Conditions
Brief summary
* Trial objective: To test the hypothesis that remote per-postconditioning in connection with primary PCI will reduce myocardial infarct size patients with STEMI. * Trial Design: Placebo controlled randomized study with parallel groups * Primary Endpoint: Myocardial infarct size expressed as a percentage of the myocardium at risk determined by Cardiac Magnetic Resonance (CMR) day 4-7 * Efficacy Parameters: Myocardial infarct size expressed as a percentage to the myocardium at risk determined by CMR at 6 months. * Global left ventricular function determined by left ventricular ejection fraction determined by CMR. * Microvascular obstruction determined by CMR day 4-7. Quantified ECV (extracellular volume) in left ventricular as myocardium at risk day 4-7 and remodelling parameters day 180. * Safety Parameters: Major adverse cardiovascular events.
Detailed description
See above. 3 patients left to include.
