Abstract
BACKGROUND Even among biomarker-negative patients undergoing elective percutaneous coronary intervention (PCI), periprocedural thrombotic and bleeding complications can lead to increased morbidity and mortality. Whether stronger platelet inhibition by an intensified oral loading strategy (ILS) before PCI impacts on outcomes among these patients in contemporary practice remains unclear. METHODS This multicenter, randomized, assessor-blinded trial tested the hypothesis that in elective PCI prasugrel 60 mg (ILS) is superior to standard loading strategy with clopidogrel 600 mg regarding a composite primary end point of all-cause death, any myocardial infarction, definite/probable stent thrombosis, stroke, or urgent vessel revascularization. After PCI, all patients were on clopidogrel 75 mg/day and aspirin. The trial was terminated prematurely because of slower-than-expected recruitment and funding discontinuation. RESULTS Of 781 patients included in the final analysis, 382 were assigned to ILS and 399 to standard loading strategy. At 30 days, the primary end point occurred in 66 patients (17.3%) assigned to ILS and 74 patients (18.6%) assigned to standard loading strategy (odds ratio, 0.92 95{\%} CI, 0.63-1.32; P=0.64). Any myocardial infarction and Bleeding Academic Research Consortium $\geq$2 bleeding rates were similar among ILS and standard loading strategy groups 16.2{\%} versus 17.5{\%}, odds ratio, 0.91 (95{\%} CI, 0.62-1.32), P=0.62 and 4.2{\%} versus 4.8{\%}, odds ratio 0.87 (95{\%} CI, 0.44-1.73), P=0.70, respectively. CONCLUSIONS In biomarker-negative stable and unstable angina patients undergoing elective PCI, the trial did not find a conclusive difference in efficacy or safety. This observation should be interpreted in the context of wide CIs and premature termination of the trial.
