One danger on this hand is that partner has responded with a three-card heart suit when he has diamonds that were insufficient to pass a takeout double. However the risk of trying to cope with this possibility have to be weighed against the danger of missing game or finding a different wrong spot.
For example, I think 2♠ is an option that guards against this danger and will help you find the right game when partner is 3-3 in the majors. If partner passes 2♠, which I guess will happen with a completely worthless hand, then you will probably be in a playable spot. Otherwise you will find game somewhere. Of course they almost certainly have a diamond ruff at trick two in this case, but hopefully they will also be endplayed at trick three.
When partner is 3-4 in the majors, he will raise two spades and now you might not be able to play in the 4-4 heart fit when you have a 5-3 spade fit. No-one said bridge was easy.
It helps if your partner is expecting a strong and flexible hand for this action rather than a spade single-suiter.
With my regular partner I would bid 2♠. With many other partners I would just bid 4♥.
I agree with Paul - I am worried that partner is 2344, 33(43), or 3352/2353 and can't pass our double for penalty. If I had 5 Hearts instead of 4 with this point count, I would go straight to game.
As is, I would bid 2
♠. It is mostly forcing, and I can get a better idea. If partner passes, we are probably in the best spot, since my hand loses value if I can't take finesses.
