New Research Shows – Heart Inflammation After COVID Vaxx More Common Than CDC Claims

A new study published in JAMA shows 1 in 100,000 people had vaccine-related myocarditis and 1.8 in 100,000 people had pericarditis — compared to the CDC’s data that 4.8 people per 1 million suffer myocarditis after receiving a COVID vaccine.

U.S. public health officials claim cases of myocarditis and pericarditis following COVID vaccination are rare — but new research published online in the Journal of American Medical Association (JAMA) shows they may happen more often than reported.

Post-vaccine myocarditis and pericarditis also appear to represent two “distinct syndromes,” Dr. George Diaz, with the Providence Regional Medical Center Everett, told Medscape Cardiology.

Diaz and colleagues reviewed 2,000,287 electronic medical records (EMR) of people who received at least one COVID vaccination.

The records, obtained from 40 hospitals in Washington, Oregon, Montana and California, showed 20 people had vaccine-related myocarditis (1.0 per 100,000) and 37 had pericarditis (1.8 per 100,000).

A recent report, by the Centers for Disease Control and Prevention (CDC), based on data from the Vaccine Adverse Events Reporting System (VAERS), suggested an incidence of myocarditis of about 4.8 cases per 1 million following receipt of an mRNA COVID vaccine.

The median age of the CDC report’s cohort was 57 years, and 59% were women. Only 77% received more than one dose. Fifty-three percent received Pfizer, 44% Moderna and 3% received Johnson & Johnson’s (J&J) COVID vaccine.

Myocarditis is inflammation of the heart muscle that can lead to cardiac arrhythmia and death. According to researchers at the National Organization for Rare Disorders, myocarditis can result from infections, but “more commonly the myocarditis is a result of the body’s immune reaction to the initial heart damage.”

Pericarditis is often used interchangeably with myocarditis and refers to inflammation of the pericardium, the thin sac surrounding the heart.

The new JAMA study showed a “similar pattern [to the CDC study], although at higher incidence [of myocarditis and pericarditis] after vaccination, suggesting vaccine adverse event under-reporting.”

The JAMA report also stated: “Additionally, pericarditis may be more common than myocarditis among older patients.”

“Our study resulted in higher numbers of cases probably because we searched the EMR, and [also because] VAERS requires doctors to report suspected cases voluntarily,” Diaz told Medscape. Also, in the governments’ statistics, pericarditis and myocarditis were “lumped together,” Diaz said.

According to Tracy Høeg, physician, epidemiologist and associate researcher at UC Davis, the results of the JAMA study are telling, as recent rates correlate with vaccination.

“An important thing I would say is COVID itself does not appear to be correlated with an uptick,” Høeg said in a tweet.

Negative heart involvement Post Covid!

Fitness trackers provide conclusions related to COVID-19!
By Ask the Doctors • August 4, 2021

Dear Doctor: I had a bad case of COVID-19 last spring. It took a while, but I’m mostly OK now. The only thing is, the numbers on my Fitbit aren’t as good as they used to be, especially my heart rate. Is that because of COVID? How long until I’m back to normal?

Dear Reader: It didn’t take long for fitness trackers to evolve from their original purpose. They began as mechanical devices designed to collect basic information, like the number of steps taken and distance traveled throughout the day. Thanks to advances in tech, they quickly progressed to electronic data-collection systems.

Depending on the specific device you’re using, a fitness tracker can keep tabs on variables like distance, speed, direction and duration of movement, and even changes in elevation of the terrain. Through skin contact with an array of sensors, these devices can deliver information about a person’s heart rate while they’re active and while they’re at rest, and specifics about their heart rhythms.

Some are even equipped with sensors and software that the manufacturers say can flag potential heart issues.
A study we wrote about last year found that subtle changes in health data collected by fitness trackers were surprisingly reliable predictors that someone was about to come down with the flu.

The same predictive ability proved true with people who became ill with COVID-19.

Now, sensors and algorithms are offering up conclusions related to long-haul COVID. As many of you doubtless know, that’s the name for the array of ongoing symptoms that some people experience for weeks, and sometimes months, after they have recovered from the initial infection.

One of the authors of that flu study, along with other researchers in California and Michigan, has examined the fitness tracker data of 234 people who had tested positive for the coronavirus that causes COVID-19. The group they followed had been moderately to severely ill. For at least three months after an initial diagnosis, the researchers saw persistent physiological changes, including an elevated heart rate.

Because fitness trackers reveal patterns of movement, the researchers were able to identify changes to the individuals’ behavior, as well. This included a decrease in distance traveled each day and an increase in time spent sleeping.

Although similar changes were seen in a group of people who had non-COVID-19 respiratory illnesses, they resolved far more quickly.

COVID-19 has a wide range of effects. This is proving to be true of long-haul COVID as well. For people in the study who were ill with COVID-19, it took an average of 79 days for their resting heart rates to return to what they had been before they became sick.

Individuals whose illness was due to something other than COVID-19 saw their heart rates returned to normal just four days after their illness ended. For 14% of the COVID-19 group, a heart rate that was five beats faster than prior to their illness persisted for more than four months. We wish we had a better answer, but there’s no way to predict how long the after-effects of COVID-19 will last.
