This is really quite a hand you have presented us. You have only five HCP, yet opposite partner's AKxxxx of hearts and any two aces (15 HCP) you are a 78% favorite to make a 6♥ slam. Of course, if partner has a bunch of kings, queens and jacks, 4♥ may be too high. You have no way of knowing as yet, and maybe never.
My advice is to first bid 4♥. If the opponents bid 4♠, then bid 5♦ on your next turn even if partner doubles 4♠. Partner will play you for 10 red cards and not much defense, which is almost what you have. On hands like this with so much offensive potential and so little defense, you almost never want to defend.
If they now bid 5♠, and partner doubles again, you have to pass. Enough is enough.
