The fact that music tuned to 432 Hz might sound slightly off to listeners might explain the change in attention, which in turn might explain the change in heart rate.

It would have been helpful measure other tuning values like 430 or 445 Hz to determine if it's caused by 432 Hz specifically.

How did they transform the original music to A=432Hz? If they did it in the naïve way, it would result in a decrease in tempo by almost 2%.

Good question, but nowadays all video players and platforms are able to increase/decrease the speed of a video without affecting the audio's pitch, so I guess the reverse is also widespread...

i'm also guessing they didn't test different temperament tunings either, which is a shame given that the whole argument for 432Hz has to do with mathematical symmetry
