Untimely Myocardial Infarction or COVID-19 Vaccine Side Effect

We present the case of a 96-year-old female, with no known cardiac history, who suffered a myocardial infarction (MI) one hour after her first Moderna coronavirus disease 2019 (COVID-19) vaccination. The patient was medically managed and discharged three days later. We are unable to attribute the cause of the patient’s MI to the Moderna vaccine unless further data are published. As healthcare providers, we need to be aware of attempts to correlate bad outcomes with the vaccine without substantiated data, and anticipate patient questions that may arise from these reports. Any research on the topic should be written carefully and avoid overstating the findings. If more reports of serious side effects in older adults are published, providers should consider additional screenings prior to COVID-19 vaccination.
