Insights
Essential thrombocythemia (ET) rarely causes coronary artery thrombosis. This case highlights acute myocardial infarction (MI) due to ET, successfully treated with angioplasty and stenting.
Area of Science:
- Cardiology
- Hematology
Background:
- Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterized by elevated platelet counts.
- ET can lead to systemic vascular thrombosis, but coronary artery involvement is uncommon.
Observation:
- A 67-year-old male with ET presented with severe chest pain.
- Coronary angiography revealed subtotal thrombotic occlusion of the left main trunk (LMT) coronary artery.
Findings:
- Successful coronary angioplasty and stenting were performed for the LMT occlusion.
- Follow-up angiography showed no significant restenosis after 4 weeks.
Implications:
- This case underscores the rare but serious risk of acute myocardial infarction in ET patients.
- Coronary stenting and antiplatelet therapy can be effective in managing ET-related coronary thrombosis.
Abstract:
Essential thrombocythemia (ET) can cause systemic vascular thrombosis, but involvement of coronary arteries in the setting of ET is rare. This report describes a case of acute myocardial infarction (MI) in a patient with ET. A 67-year-old man with ET complained of severe acute chest pain. Emergent coronary angiography revealed subtotal thrombotic occlusion of the left main trunk (LMT) coronary artery. Coronary angioplasty and stenting were performed successfully. Coronary angiography 4 weeks later revealed no significant restenosis. The patient has done well after primary coronary stenting with the use of only an antiplatelet agent to treat the thrombocythemia.
