Résumé
BACKGROUND: The reasons that decreased glomerular filtration rate (GFR) might alter the clinical efficacy of clopidogrel are poorly understood. STUDY DESIGN: In this study, we sought to evaluate whether decreased GFR alters platelet response to clopidogrel in patients receiving a maintenance dose of clopidogrel (75 mg/d for at least 8 days). SETTINGS & PARTICIPANTS: 126 consecutive patients categorized by estimated GFR: stages 1-2 (>60 mL/min/1.73 m(2); n = 29), stage 3a (45-59 mL/min/1.73 m(2); n = 21); stage 3b (30-44 mL/min/1.73 m(2); n = 26), stage 4 (15-29 mL/min/1.73 m(2); n = 14), and stage 5 (/=61% and in the VerifyNow turbidimetric-based assay as a value >235 PRU (adenosine diphosphate receptor reaction units) or percentage of platelet inhibition /=61% occurred in 52.8% of patients with stage 5 versus 30.8% of stage 3b and 24.1% of stages 1-2 (P = 0.1). PRU >235 was found in 63.6% of patients with stage 5 versus 36.8% of stage 3b and 17.2% of stages 1-2 (P = 0.005). Inhibition
