Table 1. High-risk clinical and angiographic features for thrombotic events
Feature: Clinical
  • Before myocardial infarction or troponin-positive acute coronary syndrome
  • Diabetes mellitus treated with oral hypoglycemics or insulin*
  • Chronic kidney disease (creatinine clearance ≤ 60 mL/min)
  • Previous stent thrombosis
  • Current smoker
Feature: Angiographic
  • Multiple stents (≥3 stents implanted, ≥ 3 lesions stented)15 or use of a biodegradable vascular scaffold
  • Long lesion length (>60 mm total stent length)
  • Complex lesions (bifurcation treated with 2 stents, stenting of chronic occlusion)
  • Left main or proximal LAD stenting
  • Multivessel PCI
LAD, left anterior descending artery;
PCI, percutaneous coronary intervention.

* Net benefit to diabetic patients in the absence of any of other high risk features is unclear.
