Abstract

BACKGROUND:

Several studies have shown that inhibition of the glycoprotein IIb/IIIa receptor can reduce myocardial injury during percutaneous coronary intervention (PCI). The present study was performed to investigate platelet function, using a bedside diagnostic system, to test the hypothesis that patients with activated platelets have an increased risk for myocardial injury during PCI. Such information would be valuable to guide the PCI operator to whom he or she should give a glycoprotein IIb/IIIa inhibitor during and after the procedure.

METHODS:

155 consecutive patients undergoing PCI were included in the study. 94 of the patients had stable angina pectoris and the remaining patients had unstable angina pectoris or ongoing myocardial infarction. Troponin T levels were measured in serum before PCI and at 6 am the day after PCI by an immunoassay. Platelet function was analyzed in arterial blood before PCI using the platelet function analyzer PFA-100(R) by Dade Behring.

RESULTS:

The platelet function analyzer PFA-100(R) could not discriminate between patients with or without myocardial injury during the procedure but between patients with or without acetyl salicylic acid.

CONCLUSION:

The platelet function analyzer PFA-100(R) cannot be used to guide the PCI operator to whom he or she should give a glycoprotein IIb/IIIa inhibitor but the results indicate that PFA-100(R) can be used to monitor platelet effects of ASA therapy.
