NCT01328470

Brief Summary

Impaired renal function is associated with reduced responsiveness to clopidogrel. There are no studies which have shown a means by which to overcome platelet hyporesponsiveness in patients with chronic kidney disease (CKD). The purpose of this study was to determine the functional impact of cilostazol in patients with CKD undergoing hemodialysis.

Outcome Measures

Primary Outcomes (1)

  • The differences of platelet aggregation according to the anti-platelet therapy.

    Platelet function was assessed with light transmittance aggregometry and the VerifyNowTM P2Y12 assay. High on-treatment platelet reactivity was defined as 5 μmol/L of ADP-induced Aggmax \> 50%. Inhibition of platelet aggregation (IPA) was defined as the percent decrease in aggregation values obtained at baseline and after treatment. VerifyNow-P2Y12 assay results are also assessed and expressed in P2Y12 reaction units (PRUs) and the percentage of inhibition.

    14 days

Secondary Outcomes (1)

  • Changes of platelet activation markers according to the anti-platelet therapy

    14 days

Study Arms (4)

clopidogrel 75 mg/day

ACTIVE COMPARATOR

CKD patients undergoing chronic hemodialysis and PCI for stable coronary artery disease will be randomized to receive clopidogrel 75 mg/day for 14 days.

Drug: Clopidogrel, cilostazol

clopidogrel 150 mg/day

ACTIVE COMPARATOR

CKD patients undergoing chronic hemodialysis and PCI for stable coronary artery disease will be randomized to receive clopidogrel 150 mg/day for 14 days.

Drug: Clopidogrel, cilostazol

adjunctive cilostazol

ACTIVE COMPARATOR

CKD patients undergoing chronic hemodialysis and PCI for stable coronary artery disease will be randomized to receive co-administration of adjunctive cilostazol (100 mg twice daily) and clopidogrel (75 mg/day; \[group 3, 20 patients\]) for 14 days.

Drug: Clopidogrel, cilostazol

75mg clopidogrel

ACTIVE COMPARATOR

control group undergoing PCI for stable angina will be also maintained on clopidogrel (75 mg/day for 14 days).

Drug: Clopidogrel, cilostazol
