Your comment makes no sense. The article blames Covid for a sudden increase:
> A 2022 study published in the Journal of Medical Virology found that heart attack deaths increased by 14 percent within the first year of the pandemic.
So if I were to blame the 14% increase on the vaccine instead, sources predating the pandemic wouldn't matter.
I mean, "within the first year of the pandemic" presumably means "between Jan 2020 and Jan 2021", and the vaccines didn't become widely available [to all people 16 and older] until Apr 2021, so I wouldn't blame that 14% increase on the vaccine.
I'm just saying: The original comment made it sound like (in the context of "heart attacks are rising"), as if any increase within the pandemic is already (or mostly...) covered by sources predating the pandemic and thus drawing any link to the vaccine would be invalid. These (wrong!) hand-holding statements annoy me, that's all.
To the data: Not sure what period the study is about. Though it's well known, that MRNA vaccines cause heart related problems. Whether the rise in excess death of young people is caused by "long covid"-effects, and/or by the vaccine, is still an open question I guess. But it's a fact, that the pandemic has a long-term impact on peoples health and excess death: https://www.euromomo.eu/graphs-and-maps
