A real world registry to compare dual therapy with Dabigatran/Ticagrelor to dual therapie with Dabigatran/Clopidogrel in patients with an indication for NOAC undergoing PCI in the setting of ACS. Hypothesis: Dual therapy with Dabigatran/Ticagrelor will be non-inferior in reducing the risk of bleeding compared to Dual therapy with Dabigatran/Clopidogrel (RE-DUAL PCI trial based) in patients with an indication for NOAC undergoing PCI in the setting of ACS. Thromboembolic events, stent thrombosis and death will be evaluated for estimation of events between both groups. Data will be pooled for this secondary endpoint with data from the upcoming WOEST-3 trial to compare both treatments.


The REDUAL PCI Registry will we be an open-label multicenter registry based randomised controlled trial (RBRCT) within the ZON-HR collaboration in 4 of the 6 centers in the Netherlands: Maastricht Universitair Medisch Centrum (Maastricht), Zuyderland (Heerlen and Sittard), Vie Curi (Venlo) and Radboud Medisch Centrum (Nijmegen). Isala (Zwolle) and Canisius Wilhelmina ziekenhuis (Nijmegen) will not be part of this study. This study is Investigator initiated with an unrestricted grant from Boehringer Ingelheim (subsidising party). This study is also to be noted as a Post Authorisation Safety Study (PASS). Patients 1000 patients with an indication for NOAC, who underwent successful PCI with Drug Eluting Stent (DES) in the setting of ACS will be included and randomised at each of the 4 centers of the ZON-HR. After randomisation, patients will be treated with Dual therapy with Dabigatran/Clopidogrel or with Dabigatran/ Ticagrelor. A total of 1000 patients in 4 centers will be included: 250 patients in each center. In each center inclusion and randomisation will be executed within 48 hours after PCI. Inclusions are expected to be done within 1 year. After inclusion of the interventional (Dual therapy with Dabigatran/Ticagrelor) and control group (Dual therapy with Dabigatran/Clopidogrel), follow-up of 1 year is planned.
