"cardiac arrest & acute coronary syndrome EMS calls in the 16–39-year-old population" 2019 & 2021; enabled comparison to baseline (pre-COVID epidemic) to COVID epidemic without vaccine to vaccine
'“An increase of over 25% was detected in both call types during January–May 2021, compared with the years 2019–2020. That is to say, "increased rates of vaccination ... are associated with increased number of CA [cardiac arrest] and ACS [acute coronary syndrome]." By contrast, the trial "did not detect a statistically significant association between the COVID-19 infection rates and the CA and ACS weekly call counts."
