A new study from Israel reveals that there was “no increase in the incidence of myocarditis and pericarditis” in unvaccinated adults who had COVID-19 infection.
This contradicts the findings of earlier studies that suggested there may be a connection between cardiac inflammation and coronavirus infections.
In a study published in the Journal of Clinical Medicine, the researchers concluded that there is “no increase in the incidence of myocarditis and pericarditis in COVID-19 recovered patients compared to uninfected matched controls.”
“Myocarditis and pericarditis are potential post-acute cardiac sequelae of COVID-19 infection, arising from adaptive immune responses,” the study stated. “We aimed to study the incidence of post-acute COVID-19 myocarditis and pericarditis.”
A total of 787,968 Clalit Health Services adult members were included in the study between March 2020 and January 2021. Out of that total, 196,992 adults were found to be infected with the COVID-19 virus (16,632 adults with previous vaccination were excluded from the group).
The control cohort of 590,976 adults with no Covid were age- and sex-matched, according to the study (5 adults with previous vaccination were excluded from the group).
“Nine post-COVID-19 patients developed myocarditis (0.0046%), and eleven patients were diagnosed with pericarditis (0.0056%). In the control cohort, 27 patients had myocarditis (0.0046%) and 52 had pericarditis (0.0088%),” the study stated.
“In the current large population study of subjects, who were not vaccinated against SARS-CoV-2, we observed no increase in the incidence of myocarditis or pericarditis from day 10 after positive SARS-CoV-2.”
The researchers went on and stated, “Multivariable analysis did show male sex as associated with a higher risk of developing myocarditis or pericarditis, regardless of previous COVID-19 infection.”
Dr. Peter McCullough responded to the findings.
