Effective cardio-protective strategies with the aim of reducing infarct size are therefore of great interest. Local and systemic inflammation influences the fate of ischemic myocardium and thus, adverse remodeling and clinical outcome. C-reactive protein (CRP) also acts as a potential mechanistic mediator that adversely affects the amount of irreversible myocardial tissue damage after acute myocardial infarction.\n\nObjective: The main objectives of the current study are to investigate the efficacy of selective CRP apheresis, using the PentraSorb®-CRP system, as an adjunctive therapy to standard of care for patients with acute STEMI treated with primary PCI.\n\nDesign: Investigator-initiated, prospective, randomized, open-label (outcome assessors masked), controlled, multicenter, two group trial with a two-stage adaptive design.\n\nInnovation: Selective CRP apheresis offers potential to decrease infarct size and consequently improve outcome after PCI for STEMI. This is the first randomized trial investigating the impact of selective CRP apheresis on infarct size in post-STEMI patients. In perspective, the study design allows furthermore to collect robust evidence for the design of a definitive outcome study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
