Insights
Procedure characteristics of drug-eluting stents did not significantly impact myocardial infarction or death risk after non-cardiac surgery. However, first-generation stents were associated with lower all-cause death risk compared to second-generation stents.
Area of Science:
- Cardiology
- Interventional Cardiology
- Surgical Risk Assessment
Background:
- Assessing non-cardiac surgery risk in patients with recent coronary stents is crucial.
- Drug-eluting stent (DES) implantation details may influence perioperative outcomes.
- Understanding these factors aids in patient management and risk stratification.
Purpose of the Study:
- To evaluate the association between DES implantation procedure characteristics and the risk of myocardial infarction (MI) and all-cause death within 30 days after non-cardiac surgery.
- To identify specific procedural factors that may increase or decrease perioperative risks.
Main Methods:
- Retrospective analysis of patients with DES identified from the Western Denmark Heart Registry.
- Detection of non-cardiac surgical procedures and adverse events (MI, all-cause death) using Danish national registries.
- Statistical analysis to assess associations between procedural characteristics and outcomes.
Main Results:
- No significant association was found between procedural characteristics (arteries/lesions treated, segments treated, stent length, number of stents, balloon diameter) and the risk of MI or all-cause death.
- A lower risk of all-cause death, but not MI, was observed with first-generation DES compared to second-generation DES.
Conclusions:
- DES implantation procedural characteristics do not appear to significantly influence the risk of MI or death within 30 days post-non-cardiac surgery.
- First-generation DES may be associated with a lower risk of all-cause death compared to second-generation DES in this context.
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.
