Myocarditis News and Research

RSS

In medicine (cardiology), myocarditis is inflammation of heart muscle (myocardium). It resembles a heart attack but coronary arteries are not blocked.

US health officials knowingly relied on flawed vaccine safety algorithm

US health officials knowingly relied on a compromised algorithm to detect signals of harm from mRNA covid-19 vaccines and silenced efforts to fix it, finds an investigation published by The BMJ today.

The US switch in shingles vaccines revealed an unexpected heart health pattern

In a natural experiment involving 72,920 propensity-matched US adults aged 60 years and older, recombinant shingles vaccination was associated with a 9% lower cardiovascular disease burden over seven years compared with the live attenuated vaccine. Lower burdens of ischemic heart disease and heart failure were seen in both sexes, while ischemic stroke was significantly lower only among men, supporting further clinical trials and mechanistic studies

Rising tick-borne disease in Canada can trigger heart inflammation

Move over, Lyme disease - there's another tick-borne disease to worry about in Canada. Anaplasmosis, the second most common tick-borne disease in the country, can cause a range of health issues, including myocarditis (inflammation of the heart muscle).

Australia’s diphtheria outbreak shows why boosters, antibiotics, and better housing all matter

A 131-case diphtheria outbreak in Australia’s Northern Territory showed how toxigenic Corynebacterium diphtheriae can re-emerge even in highly vaccinated populations. Genomic and epidemiological evidence linked most cases to a dominant ST381 strain, with transmission shaped by overcrowding, poor skin health, and persistent health inequities.

GLP-1 therapies linked to fewer complications in adults with both obesity and autoimmune disease

Among adults with both obesity and an autoimmune disease, those taking a glucagon-like peptide-receptor 1 agonist (GLP-1RA) medication had lower rates of emergency department visits and were less likely to experience serious cardiac events, such as stroke, pulmonary embolism or death when compared to similar adults who were not taking these medications, according to new research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Early myocarditis onset after immunotherapy linked to higher fatality risk

Patients who developed myocarditis within the first month of receiving immune checkpoint inhibitor therapy were more likely to die of myocarditis, and myocarditis-specific fatality was more common in patients who experienced co-occurring myositis and myasthenia gravis, according to results from a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

Dual imaging reveals hidden causes of heart attacks without blockages

When Ashley Perlow felt a sharp pain shoot across her chest and into both wrists, she didn't think it could be a heart attack. She was 36, a new mom, and otherwise healthy.

How zinc deficiency could worsen heart inflammation and what that means for patients

This review examines how zinc regulates inflammatory and redox signaling pathways involved in myocarditis and pericarditis, highlighting mechanisms such as NF-κB inhibition and the redox zinc switch. The authors conclude that maintaining optimal zinc status may support cardiovascular resilience, while emphasizing that clinical translation requires further targeted trials.
