Clopidogrel therapy in patients undergoing coronary stenting: Value of a high‐loading‐dose regimen

The objective of this study was to assess the value of a clopidogrel regimen based on a high loading dose initiated before the stent placement procedure. A consecutive series of 864 patients treated with a high‐loading‐dose clopidogrel regimen (600 mg given 2–4 hr prior to intervention) was compared with 870 patients treated with conventional ticlopidine therapy. Abciximab was given periprocedurally in 62% of the patients. The composite endpoint of death, myocardial infarction, or urgent revascularization was reached by 39 (4.5%) clopidogrel patients and 59 (6.8%) ticlopidine patients. Clopidogrel therapy was associated with a 35% reduction of the risk for early adverse events (odds ratio 0.65; 95% confidence interval, 0.43–0.98). Thus, a high‐loading‐dose clopidogrel regimen in patients undergoing coronary artery stenting was safe and led to a more favorable clinical outcome than conventional therapy with ticlopidine regardless of concomitant treatment with abciximab.
