Chest pain in emergency department: A diagnosis of diabetic ketoacidosis must be ruled out

Introduction: Diabetic ketoacidosis (DKA) is a common diabetic complication presenting to the Emergency Department (ED). Early recognition and initial aggressive treatment of DKA decreases morbidity and mortality. Clinical presentations of DKA are non specific such as nausea, vomiting, dehydration and abdominal pain. Chest pain is unusual presentation of DKA, however, acute coronary syndrome and pericarditis that manifest with chest pain are known precipitating factors of DKA. Case Report: We report a case of a middle aged diabetic patient who was presented with severe chest pain and elevated creatine kinase that might have thrown us off the correct diagnosis of DKA. Conclusion: A description of his presentations and acute management, along with review of literatures, is presented.
