Jun 29 (Reuters) – Members of the U.S. Army who have been vaccinated against COVID-19 have a higher than expected rate of heart inflammation Although such symptoms are still very rare. according to a study published Tuesday.
The study found that 23 previously healthy men, with an average age of 25, experienced chest pain within four days of vaccinating against COVID-19. The rate of such incidents was higher than previously anticipated.
All patients who have recovered from or are recovering from myocardial infarction which is an inflammation of the heart muscle It has been vaccinated by Pfizer Inc and BioNTech SE or Moderna Inc.
last week US health regulators It added a warning to the literature accompanying those mRNA vaccines to identify a rare risk of heart inflammation. which is more common in young men But they say the benefits of shooting in preventing COVID-19 clearly outweigh the risks.
The study, published in the medical journal JAMA Cardiology, showed that 19 of the patients were members of the Armed Forces who received the second dose of vaccine, others received one dose or retired from the military.
General population estimates would project eight or fewer myocardial infarction cases out of 436,000 male military members who received two COVID-19 vaccines.
A panel of outside experts consulting the U.S. Centers for Disease Control and Prevention (CDC) said last week that reports of myocardial ischemia among men were outnumbered. and in the week after the second vaccine dose was greater than expected in the general population. A presentation at that meeting found that heart conditions occur at a rate of about 12.6 cases per million people vaccinated.
Eight military patients in the study were scanned for diagnosis and showed signs of heart inflammation that could not be explained by other causes. Patients in the study ranged from ages 20 to 51.
The CDC began investigating the link between the mRNA vaccine and myocarditis in April. After Israel said it was studying the case among vaccinated people Pfizer/BioNTech there, and after reporting that the US military Found a case as well.
Health regulators in many countries are conducting their own investigations. (Reporting by Carl O’Donnell Editing by Bill Berkrot)
