Hi....since all of your cardiac screening tests are normal (ECG, Echo and TMT), it is unlikely that the pain is cardiac.
If you still have chest pain, check Serum
Vitamin D and
Vitamin B12 level or consult orthopaedic surgeon to rule out any bone muscle issue
Triglycerides 438 is very high and warrants medicine. You have mentioned you stopped the medications....was it advised by a doctor or you stopped yourself? I would suggest repeat the
lipid profile and see.You may need to be on medications if it's still high
Next Steps
Check Serum
Vitamin D,
Vitamin B12
Meet orthopaedic surgeon
if your chest pain is central and related to meals, consult Gastroenterologist, sometimes food pipe related issues can cause such pain
