Final results of the randomised evaluation of short-term dual antiplatelet therapy in patients with acute coronary syndrome treated with a new-generation stent (REDUCE trial).

Aims: The optimal duration of DAPT in ACS patients treated with DES is still unclear. Therefore, the aim of the current study was to investigate a short versus a standard 12-month DAPT regimen in ACS patients undergoing new-generation DES implantation.

Methods And Results: REDUCE was a prospective, open-label, multicentre, investigator-initiated study that randomised 1,496 ACS patients after treatment with the COMBO stent to either three (n=751) or 12 months (n=745) of DAPT.

Randomized evaluation of short-term dual antiplatelet therapy in patients with acute coronary syndrome treated with the COMBO dual therapy stent: rationale and design of the REDUCE trial.

Background: The optimal duration of dual antiplatelet therapy (DAPT) in acute coronary syndrome (ACS) patients treated with drug eluting stents (DES) is still under debate. Recent meta-analyses on ≤6months versus 12months DAPT suggest that bleeding rates can be reduced, without a higher rate of thrombotic complications. In particular, the COMBO dual therapy stent, being associated with early re-endothelialization, may allow for a reduction of the duration of DAPT without increasing the thrombotic risk, while reducing the risk of bleeding complications.
