Objectives. The impact of age on the incidence and timing of non-cardiac surgery after coronary stent implantation is unknown. We evaluated the incidence and timing of non-cardiac surgery after drug-eluting stent (DES) implantation according to patient age. Methods. A total of 37,915 consecutive patients treated by DES implantation between February 2003 and April 2014 were included in this study. The number of patients who underwent non-cardiac surgery were as follows: 4263 (11.2%) within 1 year, 5357 (14.1%) within 2 years, and 6311 (16.6%) within 3 years of DES implantation. Patients were divided into four groups according to age: <50 years (n = 5785), between 50 and 59 years (n = 9639), between 60 and 69 years (n = 13,566), and between 70 and 79 years (n = 8925). Results. The rates of non-cardiac surgery within 1 year among patients aged <50 years, 50-59 years, 60-69 years, and 70-79 years were 8.0% (461/5785), 8.9% (855/9639), 12.1% (1636/13,566), and 14.7% (1311/8925), respectively (P-value for trend <.01). The cut-off age at which non-cardiac surgery was more likely to occur within 1 year of DES implantation was 62 years. The rate of non-cardiac surgery within 3 years of DES implantation reached a peak among patients who were 73 years old (23.9%). Conclusions. Non-cardiac surgery with requests for cessation of dual-antiplatelet treatment was frequently performed in patients ≥62 years old who were treated with DES implantation in a real-world clinical practice.
