Complications of thyroid storm include:

  • High output cardiac failure
  • Cardiac arrhythmias
  • Delirium, seizures, coma
  • Abdominal pain, diarrhea, vomiting, jaundice
  • Elevation of transaminases

A study by Mohananey et al found that out of 41,835 US patients with thyroid storm, 1% developed cardiogenic shock, with the incidence of this complication in these patients rising between 2003 and 2011 from 0.5% to 3%. However, during this same period the mortality rate from cardiogenic shock in patients with thyroid storm decreased from 60.5% to 20.9%. The highest likelihood of cardiogenic shock was in male patients with preexisting atherosclerotic or structural heart disease. [16]
