DAPT = Gold standard after ACS and DES 1 m 3 m 6 m 12 m 30 m SHORT LONG Thrombotic risk Bleeding Risk Stent thrombosis Recurrent ACS Bleeding events
Improvement of DES technology Thinner strut Biodegradable polymer Abluminal polymer Drug and polymer release → Lower risk of ST ? → Shorter DAPT possible ? Stefanini, Taniwaki, Windecker. Heart 2013

Impact of PCI Complexity on long-term DAPT benefit Factors of Complex PCI 3 Vessel PCI Bifurcation w/ 2 DES ≥ 3 DES Total DES lenth > 60 mm CTO → 17. 5% of patients 9577 patients from DAPT duration studies > 12 Mo vs 3 -6 Mo DAPT Giustino et al, JACC 2016
PEGASUS study -1. 2% +1. 2% 60 mg + 1. 5% 90 mg Bonaca et al, NEJM 2015
Choice of DAPT duration: Rule and exceptions ! After DES Improvement of DES technology Evidence that shorter DAPT is safe in low-risk patients with new DES 6 Mo as rule, shorter in high bleeding risk patients (1 -3) Longer in very selected patients After ACS 12 Mo as rule, shorter in high bleeding risk patients (1 -3 -6) Evidence that high-risk ACS pts benefit from longer DAPT (CHARISMA post-MI, DAPT post-MI, PEGASUS)
DAPT duration DAPT indication For the patient ? Optimal Duration For DES ? Minimal Duration ? Prevention of recurrent events Prevention of stent thrombosis
