Outcomes After Noncardiac Surgery Performed Within 2 Years of Percutaneous Coronary Intervention

Background Limited data exist on noncardiac surgery patients with prior percutaneous coronary intervention (PCI) in the contemporary era. The objective was to examine rate, characteristics, and outcomes of patients who underwent noncardiac surgery within 2 years of PCI and develop a risk model of factors that predict long-term postoperative outcomes among patients with recent PCI.Methods and Results Patients in the Veterans Affairs Surgical Quality Improvement Program database who underwent noncardiac surgery between October 1, 2017 and September 30, 2021 were included. Patients with versus without PCI within 2 years were propensity matched to examine major adverse cardiovascular events (MACE), defined as a 1-year composite of mortality, revascularization, and rehospitalization for myocardial infarction or stroke. Among patients with recent PCI, multivariable logistic regression was used to develop a risk model to predict 1-year postoperative MACE. Among 334 828 patients undergoing surgery, 2297 (0.68%) had PCI within 2 years. Among 9160 propensity-matched veterans, there was no difference in MACE between patients with and without preceding PCI (hazard ratio [HR], 1.04 [95% CI, 0.96-1.17]). Patients with versus without preceding PCI within 2 years had lower risk of all-cause death (HR, 0.83 [95% CI, 0.72-0.96]) but higher risk of revascularization (HR, 1.88 [95% CI, 1.50-2.36]) at 1 year. A 13-component MACE prediction model among patients with recent PCI had moderate discrimination (area under the receiver operating characteristic curve 0.73 derivation, 0.72 validation).Conclusions Among patients who underwent surgery, risk of MACE did not differ, but the risk of revascularization was higher and all-cause death was lower in patients with versus without recent PCI. A risk model can be used to stratify risk of surgery among patients with preceding PCI.
