The following information was reported: STRESS CARDIOMYOPATHY (hospitalization, medically significant) with onset Nov2021, outcome "unknown", described as "Heart attack/ right chest pain/Back pain/ Broken heart syndrome"; DIARRHOEA (hospitalization, medically significant) with onset Nov2021, outcome "unknown", described as "diarrhea"; VOMITING (hospitalization, medically significant) with onset Nov2021, outcome "unknown"; ASTHENIA (hospitalization, medically significant) with onset Nov2021, outcome "unknown", described as "weakness"; EJECTION FRACTION DECREASED (hospitalization, medically significant) with onset Jan2022, outcome "unknown", described as "Ejection fraction low"; GLAUCOMA (hospitalization, medically significant) with onset 05May2023, outcome "unknown", described as "HOLD off restarting TEPEZZA related to her Glaucoma". The patient was hospitalized for stress cardiomyopathy (start date: 01Jan2022, discharge date: Jan2022, hospitalization duration: 6 day(s)); for ejection fraction decreased, vomiting, asthenia, diarrhoea (start date: 01Jan2022, discharge date: 06Jan2022, hospitalization duration: 6 day(s)). The patient underwent the following laboratory tests and procedures: Catheterisation cardiac: (Jan2022) unknown result, notes: no stents, diagnosed with broken heart syndrome; Ejection fraction: (Jan2022) low, notes: decreased. The action taken for teprotumumab trbw was temporarily withdrawn. Therapeutic measures were taken as a result of stress cardiomyopathy, vomiting, asthenia, diarrhoea.  Clinical course: The patient received TEPEZZA (teprotumumab) for Thyroid eye disease.

Cardiac functions were monitored weekly. On 11May2022, the physician stated that Heart attack was the cause for the Ejection fraction low. On an unknown date, the patient was told to hold off restarting TEPEZZA related to her Glaucoma (Glaucoma). The patient reported that she has been told by her HCP to hold off restarting TEPEZZA related to her Glaucoma. No treatment medications was reported. Action taken regarding TEPEZZA (teprotumumab) was withdrawn (on hold) for the event heart attack/ right chest pain, back pain, broken heart syndrome and unknown for the rest all events. Action taken with TEPEZZA (teprotumumab-trbw) was withdrawn for the event Glaucoma.   The reporter assessed the Ejection fraction low as not related to the TEPEZZA. The reporter did not provide causality assessment of the rest of the events.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
