Scientists from the Norwegian Institute of Public Health found that the risk for heart inflammation after COVID-19 mRNA vaccines is highest in young men after the second vaccine dose.
The research is published in JAMA Cardiology and was conducted by Øystein Karlstad et al.
In the study, the team evaluated the risks of heart inflammation among 23.1 million residents (aged 12 years and older) of four Nordic countries.
They identified 2226 heart inflammation events. The second vaccine dose was associated with a higher risk within 28 days among all individuals aged 12 years and older.
These findings suggest that the risk of heart inflammation was highest in young males after the second COVID-19 vaccine dose.
But this risk should be balanced against the benefits of protecting against severe COVID-19 disease.
According to NIH, Heart inflammation is your body’s natural reaction to an infection or injury to the heart.
To protect your body, your white blood cells send chemicals that increase blood flow to the affected area, which can lead to redness, swelling, or pain.
Inflammation can affect the lining of your heart or valves, the heart muscle, or the tissue surrounding the heart.
Inflammation in the heart can lead to serious health problems, including an irregular heartbeat (also called arrhythmia), heart failure, and coronary heart disease.
Many things cause heart inflammation. Common causes include viral or bacterial infections and medical conditions such as autoimmune diseases.
If you care about COVID, please read studies that drugs for high blood pressure, diabetes may lower COVID-19 death risk, and breakthrough COVID infections very mild for vaccinated people.
