I ain't a doc but my thoughts are:
You shouldn't have too much too worry about. If you are fit and healthy and everything else goes ok, then as long as your doc confirms that it's more or less in the past you should be fine.
BUT I would say don't be tempted to try and hide it. Be up front with them. I know several people who have had medical problems and debated wether or not to come clean so to speak. Each time they have and have been pleasantly surprised by the CAA's positive attitude (maybe the only time you'll hear that said about them!!) If you didn't disclose it and ever had any recurrence then you would be in serious trouble - not worth it after all the blood sweat and tears!!!
Try the medical forum though
