Multivessel stent thrombosis with optical coherence tomography (OCT) utilization for therapeutic guidance

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiovascular Medicine

Background:

• Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) is a common treatment for coronary artery disease.
• Dual antiplatelet therapy (DAPT) is crucial following DES implantation to prevent stent thrombosis.
• Discontinuation of DAPT increases the risk of adverse cardiovascular events.

Observation:

• A 63-year-old male presented with an anterior ST elevation myocardial infarction (STEMI).
• Two years prior, the patient underwent PCI with DES in the left anterior descending (LAD) and circumflex arteries.
• Clopidogrel, a key component of DAPT, was discontinued several weeks before the current presentation.

Findings:

• The patient's STEMI occurred after a period of clopidogrel discontinuation.
• This suggests a potential link between cessation of DAPT and recurrent ischemic events.
• The location of the myocardial infarction in the anterior wall may relate to the previously stented LAD.

Implications:

• Premature discontinuation of DAPT after DES implantation carries significant risks.
• This case underscores the need for careful management of antiplatelet therapy duration.
• Further research into optimal DAPT duration in specific patient populations is warranted.
