That said, I think there's a pretty big leap you're taking from "playing a lot of games" and "had a heart attack at 32." Obviously, I don't know this person; but I do know a lot of folks who have gone on binge gaming sessions who have never had heart attacks.
I'm not saying there isn't any connection or that it didn't contribute in any way; however, let's be honest with ourselves and admit that a binge gaming session, while not in any way healthy and certainly a likely contributor to this person's poor health, most likely did not cause a heart attack.
