We investigated the association of perioperative antiplatelet therapy (APT) and outcomes in patients with drug-eluting stent (DES) placement for noncardiac surgery (NCS). In consecutive 23,358 patients who underwent percutaneous coronary interventions between 2005 and 2016, total of 2,179 patients that required 2,179 elective NCS after DES placement were retrospectively analyzed. A net adverse clinical event (NACE), composite of death, myocardial infarction, stent thrombosis, and major bleeding, was assessed at 30 days. Of 2,179 patients, 937 patients (43%) underwent NCS with discontinuation of APT. For overall, NACE occurred in 10 patients who discontinued APT (1.1%) and 22 patients who continued APT (1.8%) without significant differences (hazard ratio [HR] 0.60, 95% confidence interval [CI] 0.28 to 1.27, p = 0.182). Also, adjusted NACE event rates were not different between groups for overall NCSs (adjusted HR 0.76, 95% CI 0.38 to 1.52, p = 0.440), for NCSs >1, ≤12 months after DES, and for NCSs >12 months after DES. Our findings persisted (adjusted HR 1.26, 95% CI 0.51 to 3.10, p = 0.618) when those who continued dual-APT were excluded from the continuation of APT group due to a higher tendency of NACE compared with those who continued single-APT (adjusted HR 2.26, 95% CI 0.98 to 5.21, p = 0.055). However, the patients who discontinued APT for >7 days had a significantly higher NACE than those who discontinued for ≤7 days (adjusted HR 6.93, 95% CI 2.16 to 22.24, p = 0.001). In conclusion, discontinuation of APT may not be associated with higher NACEs 30 days postsurgery compared with continuation of APT, when APT was discontinued for ≤7 days in patients undergoing elective NCS after DES implantation.
