Israeli study links COVID vaccines to 25% increase in cardiac arrest, both males & females, based on data from emergency services. COVID infection itself NOT linked to significant increase

"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."
They caution that given these findings, "It is essential to raise awareness among patients and clinicians with respect to related symptoms (e.g., chest discomfort and shortness of breath) following vaccination or COVID-19 infection to ensure that potential harm is minimized."
