The assessment of bleeding and ischemic risk is a crucial step in establishing appropriate composition and duration of dual antiplatelet therapy (DAPT) in patients with acute coronary syndrome (ACS) treated with percutaneous coronary angioplasty. Evidence from recent randomized clinical trials led to some paradigm shifts in current guidelines recommendations. Options alternative to the standard 12-month DAPT duration include shorter periods of DAPT followed by single antiplatelet treatment with either aspirin or P2Y12 monotherapy, guided or unguided de-escalation DAPT, prolonged DAPT beyond the 12-month treatment period. Although DAPT composition and duration should be selected for each ACS patient on an individual basis weighing clinical and procedural variables, data from latest trials and meta-analyses may permit suggesting the most appropriate DAPT strategy according to the ischemic and bleeding risk assessed using validated tools and scores.
