Abstract

This study aimed to examine the 30-day risk of myocardial infarction (MI) and death in patients who underwent noncardiac surgery within 1 year after coronary drug-eluting stent implantation for acute coronary syndrome (ACS) or stable angina pectoris (SAP) and to compare it with the risk in surgical patients without known coronary artery disease. Patients with drug-eluting stent implantation for ACS (n = 2,291) or SAP (n = 1,804) who underwent noncardiac surgery were compared with a cohort from the general population without known coronary artery disease matched on the surgical procedure, hospital contact type, gender, and age. In patients with ACS, the 30-day MI risk was markedly increased when surgery was performed within 1 month after stenting (10% vs 0.8%; adjusted odds ratio [ORadj] 20.1, 95% confidence interval [CI] 8.85 to 45.6), whereas mortality was comparable (10% vs 8%, ORadj 1.17, 95% CI 0.76 to 1.79). When surgery was performed between 1 and 12 months after stenting, the 30-day absolute risk for MI was low but higher than in the comparison cohort (0.6% vs 0.2%, ORadj 2.18, 95% CI 0.89 to 5.38), whereas the mortality risks were similar (2.0% vs 1.8%, ORadj 1.03, 95% CI 0.69 to 1.55). In patients with SAP, the 30-day MI risk was low but higher than in the comparison cohort (0.4% vs 0.2%, ORadj 1.90, 95% CI 0.70 to 5.14), whereas the mortality risks were similar (2.2% vs 2.1%, ORadj 0.91, 95% CI 0.61 to 1.37). In conclusion, patients with ACS and SAP who underwent surgery between 1 and 12 months after stent implantation had a risk for MI and death that was similar to the risk observed in surgical patients without coronary artery disease.
