= 3h) time to angiography. Adjusted Cox proportional
hazards models evaluated interaction between randomized
treatment and time from randomization to angiography on
subsequent outcomes. Results: Overall, a benefit of ticagrelor
vs clopidogrel for cardiovascular death/myocardial
infarction/stroke was seen at day 7 (hazard ratio [HR]: 0.67, P
= 0.002), day 30 (HR: 0.81, P = 0.042), and 1 year (HR: 0.80, P
= 0.0045). There were no significant interactions in the <3h vs
>= 3h groups at any timepoint. For major bleeding, overall
there was no significant increase (HR: 1.04, 95% confidence
interval: 0.85-1.27); but there was a significant interaction
with no difference between ticagrelor and clopidogrel in the
early group (HR: 0.79), but higher bleeding risk with
ticagrelor in the late angiography group, at 7 days (HR: 1.51,
P-int = 0.002). Patterns were similar at 30 days and 1 year.
Conclusions: The benefit of ticagrelor over clopidogrel was
consistent in those undergoing early and late angiography,
supporting upstream use of ticagrelor">

Background: Guidelines suggest that "upstream" P2Y(12) receptor antagonists should be considered in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS). Hypothesis: Early use of ticagrelor in patients managed with an invasive strategy would be more effective than clopidogrel because of its more rapid onset of action and greater potency. Methods: In the PLATO trial, 6792 NSTE-ACS patients were randomized to ticagrelor or clopidogrel (started prior to angiography) and underwent angiography within 72 hours of randomization. We compared efficacy and safety outcomes of ticagrelor vs clopidogrel as a function of "early" (<3h) vs "late" (>= 3h) time to angiography. Adjusted Cox proportional hazards models evaluated interaction between randomized treatment and time from randomization to angiography on subsequent outcomes. Results: Overall, a benefit of ticagrelor vs clopidogrel for cardiovascular death/myocardial infarction/stroke was seen at day 7 (hazard ratio [HR]: 0.67, P = 0.002), day 30 (HR: 0.81, P = 0.042), and 1 year (HR: 0.80, P = 0.0045).
