The reddit post was interesting but not helpful (actionable) for other patients.

In the USA, if you experience the symptoms of a heart attack, you just take a taxi to the emergency ward, walk up to the receptionist and say, "I think I'm having a heart attack."

You will get priority over everybody else, minimal forms, and you don't need insurance to get initial treatment.

If you can think of other reasons for the symptoms, like you went to the gym for the first time the day before and have chest muscle soreness, then you can just sit in the lobby while you sort things out. (Walking up a flight of stairs at the hospital is a good DIY stress test. Some on-call doctors actually ask what entrance you arrived at, and if there's a ramp, they know you're prolly ok if you walked in.)
