Troponin is a protein in the muscles of your heart, it shouldn't be in the blood stream, and when it is that's indicative of damage to the heart muscles
In nearly all people tested, 70-90% people had elevated Troponin levels over baseline (see graph at 6:16) 3 days after being boosted
in 2.3% of those cases, the elevation was of clinical significance
nearly everyone is getting at least a small amount of heart damage on every vaccine injection, and there is valid speculation that there are placebos mixed into vaxx batches which may be responsible for those who have no symptoms, no side effects, no troponin, but also no antibody response, exactly as if they had gotten a placebo
