Abciximab i.v. Versus i.c. in Primary PCI Patients With STEMI

Randomized Comparison of Abciximab i.v. Versus i.c. in Primary PCI Patients With STEMI and Effects on Infarct Size and Microvascular Obstruction

Randomized comparison of abciximab i.v. versus i.c. in patients with STEMI undergoing primary PCI. The hypothesis is, that higher concentration of abciximab i.c. leads to improved epicardial flow, perfusion, reduction of no-reflow, reduction in infarct size and subsequently better outcome.
