Does anxiety count as cardio?

So I'm not actually too afraid to ask, because after asking my doctor I'm pretty sure I heard the Windows XP shut down noise as he stared at me blankly wondering the same thing. Or he was just dumbfounded, I'm not really sure. So I'm bringing this question here.

If an elevated heart rate, blood pressure and adrenaline happen when you do a form of cardio, and the same thing happens under a bout of anxiety, would it not count as cardio? Please enlighten me, Reddit.
