Cureus. 2024 Jun 27;16(6):e63266. doi: 10.7759/cureus.63266. eCollection 2024 Jun.

Abstract

Tacrolimus, a potent immunosuppressive agent widely used in solid organ transplantation, has been associated with numerous harmful side effects. We report an interesting case of a patient who is status post liver transplantation and who has been maintained on tacrolimus for the past 10 years. She presented in the hospital with a ST-segment elevation myocardial infarction (STEMI), with normal coronary angiography. The patient was found to have a markedly elevated tacrolimus level. After decreasing the dose of tacrolimus and starting isosorbide mononitrate, the patient's symptoms resolved, and the patient had no recurrence of symptoms.

Keywords: acute coronary syndrome; chest pain; elevated troponin; tacrolimus; vasospasm.
