However, combining a VKA with antiplatelet therapy is associated
with an increased risk of serious bleeding episodes3

lower bleeding rates than 20 mg

In Groups 2 and 3, a period of triple therapy was followed by dual
therapy using an OAC plus low-dose ASA.
ASA was selected over clopidogrel because it is used for long-term
therapy after PCI (guidelines from the ACCF/AHA/SCAI for the
management of PCI recommend continuing therapy with
ASA indefinitely)4
WOEST showed that combining
an OAC (VKA) and clopidogrel
was safe and effective1

Remarks
OAC are needed for preventing stroke.
Antiplatelet drugs are needed for preventing ST.
Combining OAC and APT increases bleeding.
Therefore, there is a need to clarify the optimal
combination regimen in terms of choice of agents,
dose and duration.
PIONEER AF-PCI is the first RCT to address this
issue with NOACs.
Given the safety and convenience advantages of
Rivaroxaban over VKA, this is of paramount
importance.
In AF and PCI, these are the facts:
