Study shows COVID-19 infection causes greater risk for heart conditions

Researchers looked at the post-vaccination risk of heart diseases and found COVID-19 infection to pose higher risk.



Despite the fact that heart problems were not reported as an adverse event in the COVID-19 vaccine trials, a recent study investigated the possibility of vaccines causing cardiac disease. However, the study discovered that people who had COVID-19 infection had a higher risk of having heart issues than those who had been vaccinated. The findings were published in Nature Medicine, and they compared the effects of COVID-19 vaccination on the body to the impact of COVID-19 infection on heart health. The researchers wanted to see if the vaccine or the virus could cause myocarditis. Myocarditis is inflammation of the heart muscle; pericarditis is inflammation of the heart's lining; and cardiac arrhythmia is an abnormal heartbeat.


The study included persons aged 16 and up who were vaccinated against COVID-19 between December 1st, 2020, and August 24th, 2021, in England. For 28 days after receiving the AstraZeneca, Pfizer, or Moderna vaccine, they were evaluated for hospitalization or death due to myocarditis, pericarditis, or cardiac arrhythmias. These findings were compared to those of patients who had been infected with COVID-19. Over the 28-day post-vaccination period and following a COVID-19 positive test, the study discovered an elevated risk of myocarditis related with the first doses of AstraZeneca and Pfizer vaccinations, as well as the first and second doses of the Moderna vaccine. The results, however, show a greater risk of myocarditis, pericarditis, and cardiac arrhythmia following COVID-19 infection than after vaccination.
