Not that I know of, the wallet was patched for an issue with Kimoto, I always ensure I am running the latest wallet but have nothing about a heartbleed patch.

From a pool side of things I have upgraded SSL on all my servers, the communication to the wallet is handled internally so no risk.

Make sure you are running the latest version of the wallet, update everything that touches your wallet and don't trust exchanges or pools that haven't explicitly explained their position on heartbleed.

In addition I would advise changing your passwords.
