Myocarditis: its association with COVID-19 and vaccines
The myocarditis disease began to resonate among people, as they associate it with the Coronavirus, ensuring that it is really alarming.
One of the reasons why Myocarditis is now named is because the European Pharmacovigilance Risk Assessment Committee (PRAC) suggested including it as another symptom of the secondary symptoms of vaccines with mRNA technology.
Despite the fact that he also inferred that the probability of its appearance is extremely low, there are individuals who prefer to avoid vaccination for fear of suffering from it.
What is myocarditis?
This is the inflammation of the heart muscle known as the myocardium, which is responsible for working with contraction to pump blood, so when it becomes inflamed, this development can become annoying.
Dr. Jorge Salinas, epidemiologist and hospital infectologist at Stanford University, assured in an interview that the best known manifestation is the appearance of fever in some cases and chest pain.
In more extreme appearances, there may be a cardiovascular decomposition, that is, the patient may have shortness of breath, swelling in the legs and in very serious cases it can even cause death.
Why does it manifest itself, and what is its relationship with the Coronavirus?
Myocarditis can appear after any disease, or as a result of a deficiency in the immune system.
Taking into account that the Coronavirus is an infection that contaminates the body, it can cause such inflammation to appear.
Some investigations have reported that the frequency of myocarditis is more than 100 per 100,000 cases in individuals with Coronavirus, although the rate before the Coronavirus existed was in the range of one to 10 cases per 100,000.
Covid-19 contamination seems to increase the danger of creating myocarditis by more than 10 times, according to the specialist.
Another important point is the severity of myocarditis, a case similar to Covid-19, it is usually mild, but it can get complicated.
The reaction changes from one individual to another if the immune system is allowed to act. In case the individual is immunized and myocarditis appears, he realizes that it will be much milder.
Does the risk increase in case of being vaccinated?
As the doctor explains, it is not entirely certain that vaccines cause myocarditis, but it could happen, although the rate is very low.
An Israeli study published in The New England Journal of Medicine, in conjunction with Harvard University and the Clalit Research Institute, shows that among patients in an Israeli health system who received a portion of the BNT162b2 mRNA immunization, The evaluated rate of myocarditis was 2.13 cases per 100,000 people.
As a result, the highest incidence occurred among male patients between 16 and 29 years of age. The presented cases of myocarditis were of moderate and mild severity.
Salinas clarified that the vaccination process tries to reduce the danger of having myocarditis. In the event that you do not have the vaccine, you will be infected with Coronavirus and in view of this, the danger of myocarditis is greater, and its severity can be erratic.
In short, coronavirus disease is dangerous, so the risk of becoming seriously ill is greater than that of immunization-related myocarditis.
Dr. Salinas added that the miracle of immunization is that it trains the body so that it does not become contaminated and thus, regardless of whether the person gets sick, it can respond in a methodical way.
The moment the infection reaches the body, it establishes a progression of deliberate limits to fight it. However, when one is not inoculated and the infection enters the body, the safe frame may act desperately and by this situation may create myocarditis.
