BACKGROUND: In the risk assessment of patients considered for non-cardiac surgery and with recent coronary stent implantation, coronary drug-eluting stent implantation procedure characteristics may be taken into account. We aimed to evaluate associations between coronary drug-eluting stent implantation procedure characteristics and the risk of myocardial infarction and all-cause death within 30 days after non-cardiac surgery.

DESIGN: Patients with coronary drug-eluting stents were identified using the Western Denmark Heart Registry. Surgical procedures performed after stent implantation were detected using the Danish National Patient Registry. We used registry-based detection of myocardial infarction and all-cause death.

RESULTS: Of 22 590 patients treated with drug-eluting stents between 2005 and 2012, 4046 underwent non-cardiac surgery within 1 and 12 months after stent implantation. We found no significant association between the risk of myocardial infarction or all-cause death within 30 days after surgery and number of arteries treated (1 [reference] vs more), number of lesions treated (1 [reference] vs more), segments treated (left main and proximal left anterior descending artery vs other [reference]), total stent length (<20 mm [reference] vs ≥20 mm), number of stents (1 [reference] vs >1) and largest balloon diameter (≥3 mm [reference] vs <3 mm). All-cause death, but not myocardial infarction, risk was lower among patients treated with first-generation vs second-generation stents (odds ratio 0.58).

CONCLUSIONS: We identified no significant associations between stent implantation procedure characteristics and risk of myocardial infarction or all-cause death among patients undergoing non-cardiac surgery. All-cause death was lower with first- vs second-generation drug-eluting stents.
