A (2022) research paper claims to record an increase in the cases of cardiac arrest and acute coronary syndrome among the 16-39-year-old population as per the (2019-2021) Israel National Emergency Services (EMS) database. This paper claims the increase in cases is related to vaccine-induced undetected severe cardiovascular side-effects. We fact-checked and found the claim to be Mostly False.
In 2022, Nature journal published a research titled, “Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave”. This research claims, “While not establishing causal relationships, the findings raise concerns regarding vaccine-induced undetected severe cardiovascular side-effects and underscore the already established causal relationship between vaccines and myocarditis, a frequent cause of unexpected cardiac arrest in young individuals”.

Did Israel see increased covid-related emergency cardiovascular events?
Not enough evidence. The research has made the conclusion based upon an increase in the National Emergency Services (EMS) calls. But the paper does not confirm whether the main outcome only represents the cases of cardiac arrest and acute coronary syndrome. Besides this, the paper doesn’t show which individuals had covid or covid vaccine during sampling. Also, there can be other reasons for the rise in cases besides covid or its vaccination.
Another problem with the methodology of the research paper is the time intervals selected for the data collection. It seems an increase in the cases within a few months of 2021 has been highlighted only when the EMS data itself shows the increase in calls since the beginning of 2020. Overall, the methodology used does not confirm whether the cases of cardiac arrest and heart attack took the covid vaccine or not.
While reading the paper, we found the conclusion to be confusing because 39 EMS calls from 2 million people as a relative difference of 25% is not justifiable as per the available data.
In conclusion, we need more studies to confirm whether EMS can be used to identify public health trends for covid and if “the findings raise concerns regarding vaccine-induced undetected severe cardiovascular side-effects and underscore the already established causal relationship between vaccines and myocarditis, a frequent cause of unexpected cardiac arrest in young individuals”. Hence, the claim remains mostly false until proven otherwise.
