A case highlighted the possibility of hyperthyroidism to cause a large area of myocardium injury and ST segment elevation in ECG, suggesting the routine thyroid testing for patients with chest pain.

  • Acute myocardial infarction (AMI) complicated by hyperthyroidism was presented by a 66-year-old female patient admitted with chest pain and palpitations to the hospital.
  • The patient had changes in blood pressure, heart rate, ECG findings (arched ST segment elevation), cardiac markers (troponin) & enzymes (CK, CK-MB). Treatment for AMI relived the patient from the symptoms but the tachycardia was persistent.
  • Upon requesting for thyroid testing patient was found to be hyperthyroid, and was referred to endrocinologist and started on propylthyouracil. The complication of AMI with hyperthyroidism could not be ruled out!
  • Then 11 days later the patient showed stabilized condition and returned to sinus rhythm and had no focal lesions in thyroid.
  • Thus the present case highlighted the possibility that hyperthyroidism might cause a large area of myocardium injury and ST segment elevation in ECG, suggesting the routine thyroid testing for patients with chest pain.
