  • There have been reports of suspected myocarditis associated with COVID-19 vaccinations in adolescents and young adults.
  • A North American study shows that most of these individuals recover quickly from symptoms.
  • More research is needed to determine the long-term effects of COVID-19 vaccine-related myocarditis.

Rare cases of myocarditis, an inflammation of the heart muscle, have been linked to COVID-19 vaccinations in adults in Israel and the US Army.

While most of these cases occurred in men under the age of 30, researchers have also reported suspected cases of the condition in Adolescents.

On June 23, 2021, the Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices reported a likely link between mRNA COVID-19 vaccination and myocarditis, especially in people younger than 39 years.

Because of the important health implications when deciding to vaccinate young people, it is vital to understand the effects of suspected myocarditis following COVID-19 vaccinations.

A recent study in the flagship journal of the American Heart Association (AHA), Edition, suggests that young people who have experienced the myocarditis side effects of COVID-19 vaccinations recover quickly.

Researchers collected data from 26 centers in the US and Canada. Using CDC guidelines to classify cases of myocarditis as probable or confirmed, 139 patients under the age of 21 showed symptoms of myocarditis within 1 month of receiving a COVID-19 vaccination before July 4, 2021.

Of the 139 teens and young adults who met the study criteria, most were white, non-Hispanic and male, with a median age of 15.8 years.

According to symptoms, laboratory data, and imaging results, approximately one-third of suspected myocarditis cases were classified as confirmed and two-thirds as probable.

Nearly 98% of all cases followed an mRNA vaccine and 91% occurred after the second vaccine dose. Chest pain, fever and shortness of breath were the most common symptoms reported by the patients.

More than 75% of those who received a cardiac MRI showed signs of inflammation or injury to the heart muscle. Most of these individuals were hospitalized for 2-3 days and their illness was considered mild. About 20% of hospitalized patients were admitted to the ICU and there were no deaths.

However, the research team noted several limitations of the study. For example, there was no comparison of the incidence or risk between those experiencing myocarditis due to the vaccination with those experiencing cardiac symptoms following COVID-19 infection.

In addition, the authors could not rule out the possibility of a viral infection causing the myocarditis.

The authors point to the need for future studies to evaluate long-term outcomes for those who have experienced myocarditis following COVID-19 vaccinations.

Underlying genetic differences or immune responses make men particularly prone to developing this heart condition. Scientists are not aware of these apparent risk factors.

dr. Sanjay Prasad, cardiologist at Mayo Clinic, London, spoke with: Medical news today regarding the need for specific follow-ups of this study:

“Important questions to address are why this subgroup was more susceptible, and for those who developed myocarditis after one dose, how and when should they receive the second dose?”

In an interview with MNTexplained Dr. Ryan Serrano, assistant professor of clinical pediatrics at Indiana University School of Medicine in Indianapolis, how the results matched his own observation:

“The patient characteristics and outcomes described here are consistent with our own experience with post-vaccine-related myocarditis, in that most cases are mild without major involvement, such as cardiac dysfunction or arrhythmia, and patients recover quickly, especially when compared to patients who have had myocarditis due to myocarditis. a viral infection such as COVID-19.”

He also agrees with the need for more research regarding the future safety of people with myocarditis, especially those who are athletes:

“Athletes experiencing viral myocarditis should be banned from sports for 3-6 months,” says Dr. Serrano. However, as supported by this study, myocarditis appears to be milder after vaccination with a faster recovery time. “Should these athletes rest for 3-6 months, or can they return to the field safely earlier?” he adds.

The researchers state that myocarditis, even though the majority is mild, is a cause for great concern. However, the risk must be weighed against critical illnesses associated with COVID-19.

“Overall, I still think the personal and public health benefits significantly outweigh the risk, and I still recommend that all parents get their children vaccinated when they are age-appropriate.”

The researchers conclude that myocarditis from the COVID-19 vaccine that occurs in individuals under the age of 21 quickly resolves with only mild symptoms.

However, they recommend health professionals be alert to boys and young male adults who have chest pain after receiving a COVID-19 vaccination, especially in the first week after the second vaccination.
