Abstract:
ZIEL: Antiaggregatorischer Einfuss von 600 mg Loading Dosis Clopidogrel bei Patienten mit chronischer Statintherapie (Atorvastatin bzw. Simvastatin) vor geplanter Koronarintervention.
METHODEN UND ERGEBNISSE: Entnahme von Blutproben frühestens nach Gabe von 100 mg Aspirin und 600 mg Loading Dosis Clopidogrel und vor geplanter Koronarintervention bei 90 Patienten ohne Statintherapie und 90 Patienten mit chronischer (mindestens 4-wöchiger) Statintherapie (Atorvastatin und Simvastatin).Bestimmung der maximalen und residuellen Aggregation als Antwort auf ADP (5, 20 µmol/l). Durchflusszytometrische ADP(5,20µmol/l)-induzierte Bestimmung der Oberflächenexpression von GP IIb/IIIa (CD61) und P-Selektin (CD62).
ZUSAMMENFASSUNG: Die Inhibition der ADP-induzierten Plättchenaggregation wurde durch begleitende Statintherapie nicht beeinflusst.

AIMS: To test prospectively whether the antiplatelet effect of a 600 mg loading dose of clopidogrel is attenuated in patients receiving atorvastatin and simvastatin for at least 4 weeks prior to coronary artery stenting.
METHODS AND RESULTS: Blood samples were obtained at least 2 h after receiving 100 mg aspirin and 600 mg clopidogrel and prior to coronary stenting from 90 patients without statin therapy and 90 patients with statin (atorvastatin and simvastatin) therapy for at least 4 weeks. Maximal and residual platelet aggregation was evaluated with optical aggregometry in response to ADP (5 and 20 micromol/l). Surface expression of IIb/IIIa (CD61) and P-selectin (CD62) was assessed with whole blood flow-cytometry at baseline and following stimulation (5 and 20 micromol/l ADP). Inhibition of ADP-induced platelet aggregation was not impaired in the presence of concomitant statin therapy. Moreover, patients with and without statin therapy did not differ in respect to all flow-cytometric parameters obtained.
CONCLUSION: The antiplatelet effect of a high, 600 mg loading dose of clopidogrel is not diminished in patients receiving atorvastatin and simvastatin for at least 4 weeks prior to coronary stenting.
