29. In clopidogrel-treated patients, measuring ADP-dependent platelet reactivity with platelet function assays may be considered to predict the risk of ST and bleeding after PCI. IIbB Where the availability of prasugrel and ticagrelor is restricted or limited to certain indications, platelet function testing may be considered to identify patients with HPR, who are at heightened risk for thrombotic complications on clopidogrel and require a potent P2Y12- inhibitor (prasugrel or ticagrelor). IIbC Administration of high-dose clopidogrel in ACS patients with HPR is not recommended. IIIB Platelet reactivity is one of the most important prognostic biomarkers after PCI to PREDICT outcomes -- Low platelet reactivity (LPR) predicts the risk for bleeding -- These results suggest the relevance of a therapeutic window for P2Y12- inhibitors -- 29
