Summary

Background: In patients with acute ST-elevation myocardial infarction (STEMI), the amount of infarcted myocardium (infarct size) is known to be a major predictor for adverse remodeling and recurrent adverse cardiovascular events. 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.

Objective: 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.

Design: Investigator-initiated, prospective, randomized, open-label (outcome assessors masked), controlled, multicenter, two group trial with a two-stage adaptive design.

Innovation: 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.

Interventions

DEVICE

Selective CRP apheresis using the PentraSorb®-CRP system

Selective CRP apheresis as an adjunct to standard of care. Apheresis using the PentraSorb®-CRP system will be performed at day 1, 2 and 3 after PCI.
