Is it safe to go skydiving if you have a heart condition?

I've always wanted to go skydiving and my 21st is coming up so I want do do it. I'm not worried about me.... I want to skydive with my husband.. I think it would be fun and good for him..... he's always so serious (he's an accountant go figure ) He needs to do something crazy lol. but.... he's 53 and he had a heart attack 6 years ago (myocardial infaction) and he takes medication (beta blockers, lipex & some other stuff). Is it safe for him to go skydiving??? I mean its jumping out of a plane from 15,000 feet which is pretty scary...... Any advice from doctors?
