Thank you for posting your query. I can understand your concern.
In any case of acute chest the worst possibility is
acute myocardial infarction or A.M.I (
heart attack) which in your case has been hopefully ruled out by the EKGs and Lab tests.
Now, 42% of the chest pains without Myocardial infarction occurs due to gastro-oesophageal causes like gastritis , gallstone. Other causes like inflammation of the covering of heart 9
pericarditis) , pneumonia (infection of lung) , a bulging of the wall of a great vessel called aorta (
aortic aneurysm) can also cause
chest discomfort.
Look for alarming symptoms like chest pain radiating to the left arm, sweating ; in that case immediately take him to the E.R.
I would suggest you to give him a combination of Pantoprazole 40 mg and Domperidone 30 mg every morning in an empty stomach for 10 days.
I would also suggest you to take him to a cardiologist , who can correlate the labs and EKG clinically.
Hope this helps.
Post any other question. We will be happy to help.
Have a nice day. Regards.
