Covid Vaccines Linked to 'Silent' Heart Muscle Changes in New Study
A recent study by a team of scholars has uncovered 'silent' changes in heart muscle function among Covid-vaccinated individuals. The findings, published in JAMA Cardiology, were unexpected as vaccines were not anticipated to affect the heart. The study, led by an unidentified research team, found that vaccinated patients had higher myocardial SUVmax, regardless of sex or age, compared to non-vaccinated counterparts. This was measured through myocardial Fluorine-fluorodeoxyglucose (F-FDG) uptake, indicating an abnormally high demand for glucose and suggesting abnormal cardiac function. The study showed a pattern of greater response due to the Moderna vaccine compared to Pfizer, although the difference did not reach statistical significance. Dr. Bluemke, the editor of the magazine, published an editorial discussing these findings and calling for further research. The editorial noted that the findings are not due to chance, with a P value of less than .0001. Increased myocardial FDG uptake was observed in patients imaged at various times after their second vaccination. The study suggests that mild asymptomatic myocardial inflammation could be more common than previously expected among vaccinated individuals. However, more research is needed to fully understand these 'silent' changes and their potential implications. The scientific community awaits further studies to shed light on this unexpected finding.
