[Myocardial infarction in 22 year-old male with essential thrombocythaemia].

Essential thrombocythaemia (ET) is an acquired myeloproliferative disorder that causes thrombosis and haemorrhage. The association of myocardial infarction with ET is rare. We here describe a 22 year-old male patient with ET who presented with acute myocardial infarction. Coronary angiography showed multi-vessel thrombosis. Percutaneous coronary angioplasty was successfully performed. The patient was treated with abciximab after percutaneous coronary intervention. Bone marrow biopsy confirmed ET; treatment was started with interferon-alpha along with aspirin and clopidogrel without haemorrhagic complications.
