Have you talked to a cardiologist? If not, you should. You might end up doing a stress test or an echocardiogram, and ruling out or confirming various possibilities. You might end up getting prescriptions for medications that you can use when you're feeling that sort of pain.

Also, while I hesitate to recommend calling EMS out unnecessarily, you may refuse transport to the hospital even if you've called 911 for a possible emergency, in the U.S. Paramedics can do an EKG, and while hospitals can additionally use bloodwork to rule out tissue death, you could make the choice to refuse further medical treatment once the paramedics have seen no signs of a heart attack.

I do have a stress test I got my Primary Care doctor to write up that I need to schedule sometime soon.

I went to a cardiologist a few years ago, but basically he had me do a stress test and an EKG, said 'you're fine', told me to exercise 7 days a week!? for a year (like no day off, no guidance on how intense it should be, just that comment), and wanted me to see him again a year later. It didn't leave a good taste in my mouth and I didn't go back.

They did a bunch of EKGs during my episodes at the ER and they all came back normal, so I think I just need to do the stress test, for now. I had an echocardiogram done when I first went to the hospital for this a few years ago, and that was normal also.
