Pulseless ST Elevation Myocardial Infarction A Case Study on Very Late Stent Thrombosis and Advanced Management

Introduction: Start with a summary:
This case study explores a rare and complex presentation of ST elevation myocardial infarction (STEMI) resulting from very late stent thrombosis (VLST). The patient, a 75-year-old woman, faced a life-threatening condition after the withdrawal of antiplatelet therapy. This article delves into the clinical nuances of VLST, its pathophysiology, and the management strategies employed, including the use of Venoarterial Extracorporeal Membrane Oxygenation (VA-ECMO) and urgent coronary artery bypass grafting (CABG).

Main Content Sections:

• Key Findings Summary:
  The patient developed STEMI following the cessation of clopidogrel before her scheduled CABG. Immediate interventions, including PCI and VA-ECMO, stabilized her condition. A detailed angiogram revealed thrombosis at the stent site, with thrombectomy helping restore coronary flow. The case underscores the importance of recognizing peri-stent contrast staining (PSS) as a high-risk marker for stent thrombosis.
• Bullet Points:
  • Patient had a history of unstable angina treated with CYPHER™ stent placement.
  • Development of STEMI after discontinuing antiplatelet therapy.
  • Immediate use of VA-ECMO and aspiration thrombectomy.
  • Postoperative recovery without neurological complications.

Integration of External Medical Sources:
In the context of antiplatelet therapy and management of cardiogenic shock, The American Heart Association (AHA) emphasizes the need for a careful balancing act between preventing thrombosis and managing the risk of bleeding during surgery.
