The perioperative outcomes of noncardiac surgery in patients who have received second-generation drug-eluting stents (DESs) have received limited study. We reviewed the medical records of 1,748 consecutive patients who received DES at our institution (1,789 procedures) from January 1, 2009, to July 1, 2012, to determine the outcomes of subsequent noncardiac surgery. During a median follow-up of 43 months, 221 patients underwent 345 noncardiac surgeries (138 low risk, 130 intermediate risk, and 77 high risk), of which 278 were in patients with previous second-generation DES implantation. The incidence of noncardiac surgery in patients with previous second-generation DES implantation was 4.5% at 1 year, 11.6% at 2 years, and 15.2% at 3 years. The mean time from stent implantation to surgery was 21±12.9 months. Mean age was 66±8 years, 99% were men, and 11% had a perioperative complication, including 5.8% major bleeding, 2.5% acute kidney injury, 2.2% major adverse cardiac event, and 1.4% stroke. Perioperative stent thrombosis occurred in 2 patients (0.7%, 95% confidence interval 0.2% to 2.6%): 1 patient had received a DES 14 months before surgery and had stent thrombosis on the day of surgery and the other had a DES implanted 21 months before surgery and developed stent thrombosis the day after surgery. In conclusion, the incidence of perioperative complications with noncardiac surgery after second-generation DES implantation was 11% and consisted mainly of bleeding (5.8%). The incidence of definite stent thrombosis was 0.7%.
