[Diagnosis of essential thrombocythemia after myocardial infarction and cardiac arrest: A case report].

Acute coronary syndrome is now a well-known disease, with codified treatments. The main presentation is chest pain, but more and more cases are revealed by cardiorespiratory arrest thanks to pre-hospital care. And, depending on the evolution in such situations, cardiocirculatory support techniques like extracorporeal membrane oxygenation (ECMO) can be implemented. If the more common cause of SCA is atherosclerosis, consequence of the combination of one or more cardiovascular risk factors, there are rare aetiologies, which include myeloproliferative syndromes, in particular essential thrombocythemia. We describe the case of a 34-year-old man presenting with anterior ST-elevation myocardial infarction complicated by an initial cardiac arrest, whose aetiology is unknown essential thrombocythemia, and its therapeutic management requiring circulatory support by ECMO and IMPELLA(®) techniques.
