Safety and Efficacy of Glycoprotein IIb/IIIa Inhibitors in Patients With Acute Myocardial Infarction in the Presence of Intracoronary Thrombus: An Analysis From the Grand Drug-Eluting Stent Registry.

This study, performed from January 1, 2004, to November 31, 2014, at 55 centers in Korea, was based on the Grand Drug-Eluting Stent registry, which is a Korean, nationwide, multicenter, pooled registry of drug-eluting stents. The registry enrolled all-comers without any exclusion criteria except patient withdrawal of consent. A total of 1329 patients with AMI who had an overt intracoronary thrombus at the initial coronary angiography were analyzed. The efficacy end point was a 1-year major adverse cardiovascular event, defined as a composite of all death, myocardial infarction, target lesion revascularization, and stent thrombosis. The primary safety end point was any 30-day bleeding event. FINDINGS: GPIs were associated with a significantly higher rate of any bleeding events at 30 days (0.9% vs 2.9% in the non-GPI and GPI groups, respectively; P = 0.015), whereas GPI use was the only significant independent predictor of 30-day bleeding events by multivariable Cox proportional hazards regression analysis (hazard ratio = 4.76; 95% CI, 1.66-13.64; P = 0.004). Regarding the efficacy end points, no significant differences were noted according to GPI use (7.0% vs 9.0%, P = 0.287), and GPI use has no significant effect on 1-year major adverse cardiovascular events (hazard ratio = 1.33; 95% CI, 0.82-2.15; P = 0.253). IMPLICATIONS: Early upstream use of GPIs should not be considered even in the presence of an intracoronary thrombotic occlusion. ClinicalTri...
