The role of hypoglycemia in cardiovascular disease still needs to be evaluated. Incidental case studies provide direct, but so far limited, evidence for the direct impairment of heart caused by hypoglycemia. We present a case of severe hypoglycemia manifesting with acute ST elevation myocardial infarction (STEMI).

Case presentation

A 48-year old man committed a suicidal attempt by insulin self-injection. The emerged hypoglycemia was accompanied by ECG changes and positive troponins confirming the diagnosis of STEMI. Urgent coronary angiography was performed, but no acute coronary artery closure/critical stenosis was found. After resolution of hypoglycemia all signs of ischemia diminished. Insulin and C-peptide levels confirmed exogenous hyperinsulinemia, confirming insulin self-injection. Sadly, the patient suffered irreversible brain damage.


This patient case shows that severe hypoglycemia can precipitate acute STEMI.
