Yes, that's definitely possible. All of this would be much easier to decipher if the studies went deeper into cohorts of who got the vaccination and where the heart attack delta is. So if you had 4 cohorts of people and noticed their heart attack delta: covid/no vaccine, no covid/no vaccine, covid/vaccine, no covid/vaccine, that itself would tell you a lot.
Because if no covid/vaccine is showing a much higher or similar delta as covid/*, that would be pretty worrisome. I think that seems to be missing in the given study.
