Purpose: Determining the optimal duration of dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation is an important clinical issue. We evaluated the effects of ischemia (by DAPT score) and bleeding (by PRECISE-DAPT score), as well as the impact of DAPT duration, on clinical outcomes. Methods: From pooled analysis of four randomized clinical trials, 5131 patients undergoing second-generation DES implantation were randomized to short-duration (n = 2575; ≤ 6 months) or standard-duration (n = 2556; ≥ 12 months) DAPT groups. This population was further divided into four subgroups according to PRECISE-DAPT (high bleeding risk ≥ 25) and DAPT (high ischemic risk ≥ 2) scores. Results: Net clinical outcomes (1.3% vs. 1.3%; p = 0.89) and ischemic events (5.0% vs. 4.5%; p = 0.44) did not differ between the two duration groups, although bleeding events were more frequent in patients with standard-duration DAPT (0.4% vs. 0.9%; p = 0.04). Standard-duration DAPT was associated with fewer ischemic events (6.9% vs. 4.0%; p = 0.02) and no increase in bleeding events only among patients at low bleeding risk and high ischemic risk. The other groups show no differences in net clinical outcomes, ischemic events, or bleeding events according to DAPT duration. Conclusion: Compared with short-duration DAPT, standard-duration DAPT was associated with similar net clinical outcomes and ischemic events, but more bleeding events at 12 months after second-generation DES implantation. However, standard-duration DAPT reduced ischemic events without increasing bleeding events among patients at low bleeding and high ischemic risk. When determining DAPT duration, considering both ischemic and bleeding risk can help optimize patient benefits. Clinical trial registration: EXCELLENT (NCT00698607), RESET (NCT01145079), IVUS-XPL (NCT01308281), OPTIMA-C (NCT03056118).
