Studies not taking the vaccination status into account are not serious. This study even does not talk about vaccination status..
I am not saying COVID isn't cause heart attacks.
But this study is just embarrassing.
It's literally an observational summary of all filed provisional death certificates between between April 1, 2012, and March 31, 2022 limited to those that specifically mention "heart attacks" (AMI - acute myocardial infarctions) [0].
As those death certificates don't mention measles, rubella, flu, or COVID vaccinations, etc. they don't feature in a pure numerical grouping and summary.
If you feel that vaccination status play a part worthy of notice then you are free to pull the data yourself [1] and cross reference those deaths against vaccination status data.
Very few published studies are the be all to end all, they are each at best parts of a greater picture, what this study does highlight is that AMI's trended downwards for almost a decade and then rose as COVID spread.
Clearly there is more work to be down here - as this study signposts.
