Is the word apertadas the same in Brazilian and European Portuguese?

Yes

The meaning, grammar, and spelling of "apertadas" are identical in both Brazilian and European Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels are more "open" and clearly articulated. In Continental (European) Portuguese, unstressed vowels are often reduced or "closed," meaning the "e" in apertadas might be almost silent or pronounced very subtly, giving the word a more clipped sound.
