REUTERS/Dado RuvicJune 29 (Reuters) – Members of the U.S. military who were immunized against COVID-19 revealed higher-than-expected rates of heart swelling, although the condition was still very rare, according to a research study launched on Tuesday.The study discovered that 23 formerly healthy males with an average age of 25 complained of chest pain within 4 days of getting a COVID-19 shot. The incident rate was higher than some previous estimates would have anticipated, it said.All the patients, who at the time of the research studys publication had actually recuperated or were recovering from myocarditis – an inflammation of the heart muscle – had actually received shots made by either Pfizer Inc (PFE.N) and BioNTech SE (22UAy. DE) or Moderna Inc (MRNA.O). U.S. health regulators recently added a warning to the literature that accompanies those mRNA vaccines to flag the unusual danger of heart inflammation seen mainly in young males. They said the benefit of the shots in preventing COVID-19 clearly continues to outweigh the danger. find out more The research study, which was published in the JAMA Cardiology medical journal, said 19 of the patients were existing military members who had actually gotten their 2nd vaccine dose. The others received either had one dose or were retired from the military.General population quotes would have forecasted 8 or fewer cases of myocarditis from the 436,000 male military members who received two COVID-19 shots, the study said.An outside panel of professionals advising the U.S. Centers for Disease Control and Prevention (CDC) stated recently that reports of myocarditis were greater in males and in the week after the 2nd vaccine dosage than would be anticipated in the general population. A discussion at that meeting discovered the heart disease turned up at a rate of about 12.6 cases per million people vaccinated. 8 of the military patients in the study were given diagnostic scans and revealed indications of heart inflammation that might not be described by other causes, the study said. The patients in the research study varied from ages 20 to 51. The CDC started examining the prospective link in between the mRNA vaccines and myocarditis in April after Israel flagged that it was studying such cases in individuals who received the Pfizer/BioNTech vaccine there, and after a report that the U.S. military had also discovered cases.Health regulators in numerous nations are performing their own investigations.Reporting by Carl ODonnell
