This analysis, reported by TIME magazine, addressed a related concern about the Risk associated with coronavirus vaccines (RNA type) with myocarditisespecially in young men.
Myocarditis is defined by the Mayo Clinic as inflammation of the heart muscle (myocardium), which may reduce the heart’s ability to pump bloodThis condition can cause chest pain, shortness of breath, and rapid or irregular heart rhythms (known as arrhythmias).
In this regard, the research led by the professor of epidemiology and public health of the University of Versailles, Mahmoud Zureikanalyzed the medical condition of People aged 12 to 49 who had been hospitalized for myocarditis in France, from December 2020 to June 2022, when mass vaccination against Covid-19 was being carried out.
For this, They divided the patients into three groups. The first, those who developed myocarditis and were hospitalized within seven days of receiving the vaccine dose; the second, those who were hospitalized within 30 days of contracting covid, but who had not received the vaccine in the previous seven days; the third, those who had myocarditis due to other causes. All were followed for 18 months..
During that time, the study says, people with vaccine-related myocarditis were half as likely to be hospitalized again for myocarditis or heart-related events, compared with those with infection-related myocarditis or myocarditis from other causes.
In this regard, the results indicate that The risk of myocarditis associated with RNA vaccines “is very low”as Mahmoud Zurei argues, adding that the risk of Covid for the heart “is not limited to myocarditis, there are also other cardiovascular risks.”
This analysis, however, did not delve into why vaccines are linked to myocarditis or why the immune system’s response to the vaccine appears to be different from that generated by COVID-19 infection.
In this regard, Zureik said that it is likely that, as people are aware of the potential risk of myocarditis associated with the vaccine, those hospitalized due to infection after being vaccinated may present milder cases.
