Abstract:
Objective To compare the short-term efficiency and safety of high loading dose (600 mg) clopidogreal pretreatment with that of routine loading dose (300 mg) before coronary stenting in patients with acute coronary syndromes (ACS). Methods Prospective registry method was used in this study. Between February 2003 to July 2004, a total number of 316 hospitalized patients with ACS received 600 mg clopidogrel pretreatment, before coronary stenting. 309 patients with the same disease conditions who received 300 mg clopidogrel pretreatment between October 2001 to January 2003 were included as the control. The primary endpoints were the presence of subacute in-stent thrombosis. 30 days after the procedure. The composite endpoints were death of all causes, myocardial infraction and revascularization of the target ressel. The secondary endpoint was hemorrhagic events at 30 days after the stenting procedure. Results The baseline clinical and angiographic characteristics and the result of stenting between the two groups had no significants difference. Rate of subacute in-stent thrombosis was significantly lower in 600 mg group than that of 300 mg group (0.0% vs 2.6%, P=0.003). An interval of
