Why do you think these are vaso spasms or "heart spasms", has a doctor told you this? I really do not think that chest pain that far after doing exercise is related. I do a very extensive areobic exercise daily and don't think they have ever affected me hours later.
Any chest pain needs to be checked out to be safe. Yours sounds more like a musculoskeletal problem but you should get checked out to be safe, it's not worth the risk.
I hope this helps,
