You didn’t mentioned your age.
Any way,you need proper clinical examination and investigations.
Investigations include Routine hemogram,RBS,LFT,RFT, Lipid profile
of abdomen and upper GI endoscopy.
Reflux pain mimics cardiac pain so cardiovascular causes should also be screened.
Right now ,you can take proton pump

Get well soon.
