May was operated on a few days later and says he has barely had a heart issue since.
"That whole thing seems like such a long time ago now and it hasn't really bothered me physically since," says the 63-year-old.
"But I know how lucky I was."
When May, who has won the prized NZ Cup a record seven times, decided to return to driving joining the 3000 club was his main goal.
"I needed something to focus on and it was the logical thing but to get there, alongside Maurice and Tony, after everything that has happened is very special."
Even more so as many of May's family were there on Sunday to enjoy the milestone with him and the emotions flowed deepest when May drove Sheeza Artist back into the stabling area to applause from his fellow horsepeople, the rarest of all tributes in the stoic harness racing community.
"That was quite moving. I don't often get emotional but I did then."
May says now he has achieved his goal he will continue driving, enjoying his second chance at life.
