Heart inflammation caused by mild, short-term COVID vaccines: study

Damage to the heart muscle in rare cases of myocarditis after coronavirus vaccination is mild and unlikely to affect the long-term health of patients, according to a new study published by doctors and scientists at Rabin Medical Center.

The study, the largest of its kind to date, examined 15 patients between the ages of 17 and 76 who developed inflammation of the heart after their first or second puncture, using advanced magnetic resonance imaging (MRI) technologies that allow high-grade precision to diagnose the level of myocardial injury.

MRI is considered the gold standard for assessing cardiac function, according to the lead researcher, the head of Rabin’s Department of Cardiovascular Imaging, Dr. Ashraf Hamdan. He said the technology allows for a very high level of precision.

“This is the first and largest study in the world to look at the problem using MRI,” Hamdan said. “Any other study is smaller and includes only five to seven patients.”

Patients who had been diagnosed with myocarditis were examined within 42 days after their first or second injection.

The results of the study showed that the extent of the damage to the heart muscle is very slight (only about a median of 2% of the myocardial mass) and in most cases the heart function was normal.

The most common complaint was chest pain, the research showed, and all the patients were eventually discharged from the hospital.

A study published last month by the hospital’s Cardiology Department with the Clalit Research Institute had already shown the phenomenon to be rare. Among the 2.5 million Israelis who received the vaccine, only 54 experienced heart inflammation.

According to Hamdan, myocarditis appears to be an immediate autoimmune reaction and nothing more.

He said that given the mild damage and the fact that, despite some inflammation, the heart seemed to function normally, “we hope these patients will not have any problems in the future.”
