com A recent European Heart Journal study utilized data from a Swedish nationwide register-based cohort to explore the risks of cardiovascular and cerebrovascular events following vaccination against the coronavirus disease 2019 (COVID-19). Risks from COVID-19 vaccination Although rare, COVID-19 messenger ribonucleic acid (mRNA) vaccines may increase the risk of certain cardiovascular events, including myocarditis and pericarditis. The highest incidence of these events has been observed in young males within two weeks of vaccination, particularly after the second dose.
Clinical trials conducted by Pfizer and Moderna reported a low incidence of myocardial infarction (MI) among vaccinated individuals. However, there remains a lack of population-based studies on acute MI events following vaccination. Existing evidence does not indicate that COVID-19 vaccination increases the risk of MI, whereas the risk of atrial fibrillation (AF) is extremely low.
Furthermore, individual-level data has not suggested an increased risk of stroke after vaccination. Nevertheless, additional studies are needed to determine whether COVID-19 mRNA vaccines increase the risk of adverse cardiovascular health outcomes,.
