That's tough. I had a heart attack at 53, while riding the bike. I was lucky in that my stress echos all came back good, and I am riding strong.
It's really up to you. For me, I would not want to sit on my azz and start getting fatter, and sicker. They probably gave you nitro-stat. Get multiple bottles. stash one in your car, seat bag, back back if you wear on, and even your wife's purse.
I had a second event five years later. It came out of the blue. One of the stents had re occluded, and the onset was so sudden they figured that I had a "ruptured plaque" that blew a clot into the stent. It was bad, but I am back on the bike again.
I figure I can get hit by a spoiled teenager texting while driving daddy's Beemer, have "the big one", or die a low miserable death sitting on a couch.
I am not a religious person, so don't fear hell. I've lived past half a century, and have a bright grand kid who will do good in life. I have no regrets, and chose to go out living life. At the same time I am not crazy, and am not looking to die. The choice is yours.
