Abstract Background Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterized by uninhibited platelet production. It can present with vasomotor symptoms, and less commonly, severe thrombotic events such as myocardial infarction. ST-segment elevation myocardial infarction (STEMI) secondary to the hypercoagulable state in ET is a diagnostic challenge as the complication is rare, especially outside the typical demographics affected by ET such as the female and elderly populations. Case presentation Here we report a case of a 32-year-old male found to have STEMI and a markedly elevated platelet count. Angiography revealed occlusion of the left anterior descending and left circumflex arteries, requiring percutaneous intervention and Impella support. The patient was later diagnosed with essential thrombocythemia, treated with hydroxyurea and antiplatelet therapy, and discharged with a wearable cardioverter defibrillator. Conclusions This case illustrates the potential for severe thrombotic complications such as STEMI due to ET. Severe thrombotic complications are less common manifestations of ET in general, particularly in young males. Recognition and diagnosis of ET are critical for the institution of appropriate therapy and prevention of STEMI and cardiogenic shock among other complications.
