Completely unrelated I'm sure:
“mRNA-1273 booster vaccination-associated elevation of markers of myocardial injury occurred in about one out of 35 persons (2.8%)"
“mRNA-1273 booster vaccination-associated elevation of markers of myocardial injury occurred in about one out of 35 persons (2.8%)"
...and, from the study you link to:
> mRNA-1273 vaccine-associated myocardial injury was more common than previously thought, being mild and transient, and more frequent in women versus men.
"Mild and transient" does not describe a heart attack.
Obviously any form of heart damage increases the chances of heart attacks in the future. The heart is extremely poor at repairing itself.
