Key result
AstraZeneca COVID-19 vaccine linked to myocarditis presenting with exertional tachycardia in a 32-year-old female.
Why the study?
Most reported post-vaccination myocarditis cases have occurred following mRNA vaccines, with fewer reports following adenovirus vector vaccines, warranting increased awareness.
Does the AstraZeneca COVID-19 vaccine cause myocarditis?

Alerts to possible myocarditis after AstraZeneca vaccine; leaves open causality and incidence.
Coronavirus disease-19 (COVID-19) vaccines are massively administered globally and some adverse events, such as myocarditis, are being reported. Most of the reported cases of post-vaccination myocarditis have occurred following mRNA vaccinations. However, there have also been recent reports of myocarditis following adenovirus vector vaccinations. We present a case of a 32-year-old female patient who developed myocarditis following the administration of the first dose of the AstraZeneca vaccine. The patient developed inappropriate exertional tachycardia and exertional dyspnea from Day 3 and was diagnosed with myocarditis by subsequent echocardiography about 3 months later. We are unable to confirm a direct association between myocarditis and AstraZeneca vaccination. However, we would like to increase awareness regarding the possibility of developing myocarditis following AstraZeneca vaccination.

Hassanzadeh et al. (2022) conducted a case report in Myocarditis following COVID-19 vaccination (n=1). AstraZeneca COVID-19 vaccine was evaluated on Myocarditis diagnosis. A 32-year-old female developed myocarditis, presenting with inappropriate exertional tachycardia and dyspnea, following the first dose of the AstraZeneca COVID-19 vaccine.
