I'd be amazed if you could, since the DSM is the Diagnostic and Statistical Manual of Mental Disorders.
But aside from that, are you claiming that there's no such thing as a heart attack? Or are you just complaining that they didn't use the more technical term "myocardial infarction"?
ya got me bubba.....I should have typed ICD....big deal, “heart attack” ain’t in either of them, because it means nothing to medical folks, and anything or everything cardiac to foolish lay people.
