'Stanford Medicine study shows why mRNA-based COVID-19 vaccines can cause myocarditis'

"A new study implicates a pair of substances secreted by immune cells in inducing myocarditis among mRNA-based COVID-19 vaccine recipients:

Symptoms — chest pain, shortness of breath, fever and palpitations — appear in the absence of any viral infection. And they happen quickly: within one to three days after a shot. Most of those affected have high blood levels of a substance called cardiac troponin, a well-established clinical indicator of heart-muscle injury. (Cardiac troponin is normally found exclusively in the heart muscle. When found circulating in blood, it indicates damage to heart muscle cells.)

“It’s not a heart attack in the traditional sense,” he said. “There’s no blockage of blood vessels as found in most common heart attacks. When symptoms are mild and the inflammation hasn’t caused structural damage to the heart, we just observe these patients to make sure they recover.”

However, Wu noted, if the inflammation is severe the resulting heart injury can be quite debilitating, leading to hospitalizations; ICU admissions for critically ill patients; and deaths, albeit rarely."
