Risk of myocardial infarction and death after noncardiac surgery performed within the first year after coronary drug-eluting stent implantation for acute coronary syndrome or stable angina pectoris
The American Journal of Cardiology Oct 02, 2021
Thim T, Egholm G, Kristensen SD, et al. - Patients suffering from acute coronary syndrome (ACS) and stable angina pectoris (SAP) who had surgery between 1 and 12 months post-stent implantation were found to have a risk for myocardial infarction (MI) and death that was similar to the risk noted in surgical patients without coronary artery disease.
This study included patients with drug-eluting stent implantation for ACS (n = 2,291) or SAP (n = 1,804) who had noncardiac surgery vs a matched cohort from the general population without known coronary artery disease.
ACS patients exhibited markedly elevated 30-day MI risk when surgery was done within 1 month post-stenting, whereas mortality was comparable.
When surgery was done between 1 and 12 months post-stenting, a low 30-day absolute risk for MI was evident which was still higher than the comparison cohort, whereas the mortality risks were similar.
Although low 30-day MI risk was observed in SAP patients, it was still higher than in the comparison cohort, whereas mortality risks were similar.
