Myocarditis

Circulation Journal Report - A new international study found that 54 out of nearly 57000 adults (a rate of 2.4 of every 1000) hospitalized due to COVID-19 ...

- The people found to have both COVID-19-related acute myocarditis and pneumonia had a mortality rate of 15.1%, compared to no deaths during hospitalization in the people who did not have pneumonia. The Dallas-based organization has been a leading source of health information for nearly a century. Further, in some of the hospitals that were heavily hit early in the pandemic, some people with acute myocarditis may have been missed. The American Heart Association is a relentless force for a world of longer, healthier lives. Within the large study group, a total of 54 people hospitalized with COVID-19 were identified as having definite or probable acute myocarditis, based upon results of heart muscle biopsy and/or magnetic resonance imaging. The statements and conclusions in each manuscript are solely those of the study authors and do not necessarily reflect the Association’s policy or position. The people with pneumonia were older than those without pneumonia (average age of 45 years vs. - A new international study found that 54 out of nearly 57,000 adults (a rate of 2.4 of every 1,000) hospitalized due to COVID-19 infection developed acute myocarditis, an inflammation of the heart muscle often caused by viral infections. Some people were not screened for other viruses or immunological causes of myocarditis, so there may have been other contributing factors. Revenues from pharmaceutical and biotech companies, device manufacturers and health insurance providers and the Association’s overall financial information are available here. An episode of myocarditis may resolve on its own or with treatment or may result in long-lasting damage. It can weaken the heart and its electrical system, and it can make it difficult for the heart to pump blood.

Additionally, in some of the hospitals that were hit hard early in the pandemic, some people with acute myocarditis may be missing. - The subjects who were found to have both COVID-19-related acute myocarditis and pneumonia had a mortality rate of 15.1% compared with no deaths during hospitalization in the people who did not have pneumonia. In addition, 43 people with possible acute myocarditis were excluded due to lack of imaging or biopsy information. Within the large study group, a total of 54 people admitted with COVID-19 were identified as having safe or probable acute myocarditis, based on results of cardiac muscle biopsy and / or magnetic resonance imaging. Some people were not screened for other viruses or immunological causes of myocarditis, so there may have been other contributing factors. An episode of myocarditis may disappear on its own or with treatment or may result in prolonged injury. People with pneumonia were older than those without pneumonia (mean age 45 years vs. It can weaken the heart and its electrical system, and it can make it difficult for the heart to pump blood. , according to new research published today in the American Heart Association’s flagship, peer-reviewed journal Circulation. The authors note that the potential rate of COVID-19-related myocarditis may be between 1.2-5.7 per 1,000 inpatients due to COVID-19. Some people were identified with possible myocarditis based on preliminary testing, but they were not included in the final analysis because they did not meet all study protocols. “ Acute myocarditis, inflammation of the heart muscle typically triggered by a virus, occurred in about two out of every 1,000 people admitted with COVID-19 and was associated with more serious illness and complications in people with COVID-19, especially among people who also had pneumonia.

New Zealand has recorded its third death considered to be linked to the Pfizer Covid-19 vaccination.

"What I would say of course, this was a young person, a teenager, and very sad that this young person has died. This is the third death in New Zealand that is considered to be linked to the Pfizer Covid-19 vaccine. New Zealand has recorded its third death considered to be linked to the Pfizer Covid-19 vaccination.

Among COVID-19 vaccinations, we examined the effect of the type of vaccine (mRNA or non-mRNA), sex, age, and dose on the incidence of myopericarditis. This ...

- In the midst of the devastating COVID-19 pandemic, rapid development of highly effective vaccines was enthusiastically welcomed. - 82.Clinical considerations: myocarditis and pericarditis after receipt of mRNA COVID-19 vaccines among adolescents and young adults. It is also important to interpret the risks and benefits in the context of the background incidence of myopericarditis across subpopulations—ie, the risk of myopericarditis will depend on the prevailing prevalence of COVID-19 locally and at the time of vaccination. In people who received a COVID-19 vaccine, our results showed that myopericarditis was nearly four times as common in those receiving an mRNA vaccine than a non-mRNA vaccine and in those receiving their second dose of vaccine compared with a first or third dose. Additionally, given current robust vaccine surveillance systems and the fact that COVID-19 vaccines have received a much higher degree of scrutiny than previous vaccines, the possibility of relative under-reporting of adverse events following non-COVID-19 vaccinations cannot be excluded, despite mass vaccination of more than 6 billion people in the past year. We also found that young men have a higher incidence of myopericarditis than others receiving mRNA COVID-19 vaccinations. Vaccine doses, n Definitions of pericarditis, myocarditis, and myopericarditis in individual studies or databases are summarised in the 38 We clustered the pooled estimates around each unique study identifier to derive the robust-variance estimates for SE. In addition, we evaluated differences in the incidences of myocarditis and pericarditis between COVID-19 and non-COVID-19 vaccines. We also did a sensitivity analysis excluding any database and preprint data and studies with high risks of bias (JBI score <7) to assess the impact of intra-study risk of bias on the reporting of myopericarditis. The screening of studies, data collection, and risk of bias assessment were done independently in duplicate by RRL, FLT, and KR; disagreements were resolved by consensus. Although a number of mechanisms have been suggested, the actual mechanism for the pathogenesis of post-vaccine myopericarditis has not been established.

The COVID-19 Vaccine Independent Safety Monitoring Board notified the ministry it considered the death to be linked to the Comirnaty vaccine. The person's age ...

Not only were rates of myopericarditis following COVID vaccination extremely low, but they were comparable to non-COVID vaccines, a systematic review and ...

They stated that there were "common demographic and clinical features" between myopericarditis cases associated with smallpox and mRNA COVID vaccines. Lastly, vaccines against hepatitis, Haemophilus influenzae, pneumococcus and diphtheria, pertussis and tetanus were underrepresented in the literature review. As other studies have confirmed, incidence of myopericarditis was significantly higher among those who received mRNA vaccines (22.6 cases per million doses), higher in people younger than age 30 (40.9 per million), and higher in males than females (23 vs 5.1 per million). The authors highlighted that "These findings are important additions to the conversation when weighing the risks and benefits of COVID-19 vaccination during this pandemic." Myopericarditis was significantly higher following smallpox vaccination (132.1 cases per million) compared to COVID vaccination (P<0.001). And compared with COVID vaccinations, there was no significant difference in incidence of myopericarditis after influenza vaccinations (1.3 per million doses, P=0.43), they wrote in Lancet Respiratory Medicine. In an analysis of 11 studies with over 400 million vaccine doses, there was no significant difference in incidence of myopericarditis after COVID vaccines versus non-COVID vaccines (18.2 vs 56.0 cases per million doses, P=0.20), reported Kollengode Ramanathan, MD, of National University Hospital in Singapore, and colleagues.

Director-General of Health Ashley Bloomfield says the death was "very sad" and "quite sudden".

The Board said the death reported on Monday is "the third death in New Zealand that is considered to be linked to vaccination with the Pfizer Covid-19 vaccine". The Covid-19 Vaccine Independent Safety Monitoring Board said on Monday the teen had received a dose of the Pfizer vaccine in the weeks before their death. Dr Ashley Bloomfield confirmed on Tuesday that the third death in New Zealand linked to the Pfizer Covid-19 vaccine was a teenager.

The Pfizer and Moderna shots have been linked to rare cases of myocarditis, but the risk of heart complications is more likely after a COVID-19 infection ...

The CDC study found teenage boys have the highest risk of heart complications after vaccination. The study compared the risk of heart complications after COVID-19 infection to those that followed the first and second dose of the Pfizer and Moderna vaccines. In February, the CDC advised males ages 12-39 to wait eight weeks between their first and second vaccine doses to reduce the risk of myocarditis in light of research suggesting a longer wait time diminished risk.

"What I would say of course, this was a young person, a teenager, and very sad that this young person has died. This is the third death in New Zealand that is considered to be linked to the Pfizer Covid-19 vaccine. New Zealand has recorded its third death considered to be linked to the Pfizer Covid-19 vaccination.

The grieving teen's family do not want the death used by groups to undermine Covid-19 vaccine efforts, officials have advised.

Myopericarditis means that both the heart muscle and the sac are inflamed. The board considered the myocarditis was possibly due to vaccination. More than eight of 10 reported cases have recovered quickly with rest and common medications, such as ibuprofen. Symptoms of myocarditis or pericarditis linked to the vaccine generally appear within a few days, mostly within the first few weeks after vaccination, the Ministry of Health says. Covid-19 is more likely to cause myocarditis than the vaccine – almost four-times higher risk – and the risk of Covid-19 far outweighs the risk of the vaccine. The teenager had myocarditis at the time of their death in December. However, there was not enough information at the time to determine the potential role of the vaccine.

Whereas it is about the same as in influenza, measles, mumps and rubella and polio vaccines. Fever, fatigue, headache, muscle pain, chills, diarrhoea and pain at the injection site are some of the common symptoms experienced by most people. More than 10 billion doses of COVID-19 vaccines have been administered globally as of March 2022. "The risk of such rare events should be balanced against the risk of myopericarditis from infection and these findings should bolster public confidence in the safety of Covid-19 vaccinations," Ramanathan added. Part of the study read, "Nevertheless, the risks of such rare adverse events should be balanced against the risks of COVID-19 infection (including myopericarditis)." The study examined the incidence of myocarditis following COVID-19 vaccination and compare this with non-COVID-19 vaccination as well

The family of a third person whose death is considered linked to the Pfizer Covid-19 vaccine don't want the teen's case to be used to undermine vaccination ...

"The family was very clear that they did not want this death, this unfortunate and very sad death, to in any way put people off from being vaccinated or to be used by groups to try and undermine vaccination efforts in New Zealand," Bloomfield said. "The board considers that the development of myocarditis was possibly due to vaccination with the Pfizer Covid-19 vaccine." The person had received a dose of the Pfizer Covid-19 vaccine in the weeks prior to their death. In March 2022, the board met to consider all information available that showed the person had myocarditis at the time of death. In a statement last night, the Ministry of Health said the board had first reviewed the Centre for Adverse Reactions Monitoring's report of a death in December 2021 but at the time there was not enough information to determine the potential role of the vaccine. The family of a third person whose death is considered linked to the Pfizer Covid-19 vaccine don't want the teen's case to be used to undermine vaccination efforts in Aotearoa.
