Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, his
chest pain is mostly due to GERD (
gastroesophageal reflux disease) because it is improved with
antacid (gas x pills).
But better to rule out heart diseases because he is 60 years old and heart diseases are common at this age.
So
consult doctor and get done blood pressure monitoring, ecg and 2d echo.
If all these are normal then no need to worry for heart diseases.
His chest pain is more likely due to GERD.
So ask him to avoid stress and tension, avoid hot and spicy food. Avoid large meals, instead take frequent small meals. Take
proton pump inhibitors and prokinetic drugs regularly.
Quit smoking and alcohol if he have these habits.
Don't worry, he will be alright.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
