Abstract |
In patients with ST-elevation myocardial infarction (STEMI), direct intracoronary bolus administration of the glycoprotein (GP) IIb/IIIa receptor antagonist abciximab is associated with a reduction in infarct size, better myocardial salvage, less microvascular obstruction and improved myocardial blush grade as compared to intravenous bolus injection, presumably caused by higher local drug concentrations leading to a more pronounced inhibition of platelet aggregation. We investigated whether there are differences in the degree of GP IIb/IIIa receptor occupancy and platelet inhibition in blood drawn from the coronary sinus (CS) shortly after intracoronary versus intravenous abciximab bolus administration. |
