In anti-vaccine communities, there is a widespread theory, generally considered misinformation/conspiracy, that the Covid vaccines increase the rate of heart attacks and cardiac disease, and that deaths from these causes have spiked in recent months. Is that claim consistent or inconsistent with this dataset?

The Anti-vax people are nuts, so everything is kinda mixed up to serve their personal agendas and those that are "of like mind" to some extent.

This dataset speaks nothing to an existing concern. You want to look at studies like these:

COVID vaccines have triggered carditis or (possibly underlying) heart failure in people under 30 which has been expanded to all adults. I am in stage 2 heart failure (medication controlled perm afib, have to sleep on my right side or everything goes numb AND I probably have to get cardioverted, etc). I have not had a vaccine and my cardiologists have suggested I don't yet. I've had 3 open heart surgeries and my heart won't suffer another surgical insult, so although I'm super cautious, I always do what my cardiologists tell me.

The rest of my family (brother, dad, sister, etc) have been vaccinated.

(Not disagreeing with your comment, just highlighting something)

It’s worth nothing that the Israeli study linked identified 275 cases of myocarditis, all but ~14 of which were mild, out of five million doses - a far cry from the mass death and destruction due to the vaccine that the vaccine skeptics are describing.

A Covid infection of course also triggers myocarditis, and a much more severe version of it.

I believe it's arrhythmias that you've heard of. The incidence of carditis are, so far, incidental rather than attributed to COVID. It's theorized that carditis develops from overactive immune response, but that's not confirmed.

Arrhythmias are not uncommon under metabolically stressed individuals.

No, as you would expect with a virus, COVID can and does cause myocarditis, at a rate much higher than any vaccine, again, as you would expect from an active vs at most inactivated virus.

> No, as you would expect with a virus, COVID can and does cause myocarditis

I'm not sure what you mean by "No". Ofc it can cause myocarditus, as all manner of things trigger inflammation in marginal cases.

> at a rate much higher than any vaccine

Can you point to any data as justification for that conclusion?

As I understand it, this is correct.

I think you maybe posted this on the wrong thread, there is nothing in this data that correlates vaccinations with cardiovascular disease.

Especially given that this study says it's from January to April; at that point hardly any Canadians were vaccinated. Here in Ontario by the end of April only about 3% of the population had had a second dose, and about 30% had had a first dose. At the beginning of April it was only 13%.

We apparently have excess deaths data classified by cause. If these data show no excess deaths due to cardiovascular disease, then it rules out the anti-vaxxer theory. If there are excess deaths in that category, it would be consistent with the theory, although I agree it wouldn't be a correlation. However, I never asked that.

This is not the dataset you’d need to prove or disprove that.

That said, the various covid vaccines currently have research and record-keeping attention directed at them that few other things in the history of humanity can claim. If there was such a correlation I would expect somebody reputable to have shown it by now.

One of the data sets from the UK show excess deaths of heart attack and stroke in people under 50.

Granted overdoses can cause cardiac arrest.
