A 78-year-old male with inferior ST-segment elevation on electrocardiogram, diabetic ketoacidosis and acute pancreatitis.

Abstract

A 78-year-old male presented with shortness of breath, metabolic acidosis, severe hyperglycaemia and ketonemia. Inferior ST-elevation was present on 12-lead ECG with raised troponin I, but coronary arteries were normal on emergency cardiac catheterization. Despite no previous history of diabetes mellitus and normal HbA1c levels 7 months prior, diabetic ketoacidosis (DKA) was diagnosed, complicated by subsequent shock. The underlying cause was acute pancreatic disease, supported by elevated pancreatic enzyme levels and a history of chronic heavy alcohol use. There are no previous reports, to our knowledge, of patients with acute pancreatitis presenting to the ED with secondary DKA mimicking STEMI.
