Actually. I think it's the opposite in this case. That is, these are heart attacks that end up in __ER__ not all HA's. The bias is that women don't have HT's so __if__ they end up in ER then it's likely to be bad.

Can you explain what you mean by hysteria and provide some salient evidence, please?

Sure. "Hysteria" being a nonsense medical diagnosis from the past that's basically the poster child for sexism in medicine (https://en.wikipedia.org/wiki/Female_hysteria).

I bring it up because I'm suggesting that one possible explanation is that maybe this study is revealing yet remaining sexism in medicine. Just like the whole nonsense concept of hysteria, maybe professionals still discriminate by assuming women are just being "hysterical". Not consciously, but more as an artifact of western medicine and society.

I also strongly reccommend this fantastic podcast about the topic: http://www.maximumfun.org/sawbones/sawbones-hysteria

I hope this satisfies your question. I suspect I was just not clear enough that I was not legitimately suggesting hysteria as an actual explanation.

Thank you, this podcast episode looks worthwhile. I did misread your intent, I’m afraid; otherwise the history of hysteria is familiar to me.
