Late coronary stent thrombosis associated with exercise testing

Area of Science:

• Cardiology
• Interventional Cardiology
• Thrombosis Research

Background:

• Coronary stent thrombosis remains a significant complication following percutaneous coronary intervention.
• Optimal stenting results do not preclude late stent thrombosis, particularly in patients with acute myocardial infarction.

Observation:

• A 75-year-old male presented with reinfarction 6 months post-stenting of the left anterior descending artery.
• The event occurred shortly after a successful exercise stress test, despite an initially optimal stenting outcome.

Findings:

• A combined mechanical approach using AngioJet thrombectomy was employed to reduce thrombus burden.
• Adjunctive therapy with glycoprotein IIb/IIIa antagonists facilitated complete resolution of angiographic filling defects.

Implications:

• This case highlights the potential for late stent thrombosis even after optimal percutaneous coronary intervention.
• Mechanical thrombectomy combined with antiplatelet therapy offers an effective treatment strategy for acute stent thrombosis.
• Further research into risk factors and preventative strategies for late stent thrombosis is warranted.
