I think that when you get raised on the turn, you have odds to chase a 5 outer. However, you have to have the discipline to fold the river when you don't catch an ace or 5. Calling the turn raise has one advantage - when villain is semibluffing two hearts for example, you can win the hand because he will often check behind on the river with his worse hands.

But since you donked the flop, villain figures you for a made hand, so he's likely not semi-bluffing the turn.

I don't think you have 5 outs here. Villain could be slowplaying a big hand like 99, or else he's got AJ, QTh, KJ/KK. Some hands you have 5 outs against, others you are drawing dead. Plus, you don't always win a bet on the river when you have the best hand or improve to the best hand (as illustrated in this hand). So I'd probably just fold right there on the turn. As played, I would also check the river for fear of getting raised.
