Clopidogrel pre-treatment in stable angina: for all patients > 6 h before elective coronary angiography or only for angiographically selected patients a few minutes before PCI? A randomized multicentre trial PRAGUE-8.

ABSTRACT:

Aims

To compare two different clopidogrel regimens on the outcomes of patients undergoing elective coronary angiography (CAG)+/-ad hoc percutaneous coronary intervention (PCI).

Methods and results

Open-trial randomized 1028 patients with stable angina to group A ('non-selective'-clopidogrel 600 mg > 6 h before CAG; n = 513) or group B ('selective'-clopidogrel 600 mg in the cath-lab after CAG, only in case of PCI; n = 515). Combined primary endpoint was death/periprocedural myocardial infarction (MI)/stroke/re-intervention within 7 days. Secondary endpoints were troponin elevation and bleeding complications. Primary endpoint occurred in 0.8% group A patients vs. 1% group B (P = 0.749; 90% CI for the percentage difference -1.2-0.8). Periprocedural troponin elevation (> 3 x ULN
