34m with echo stress perfect in jan. acid reflux leads to gas fullness in chest why am i always thinking i will have a heart attack taken over my life?

Acid reflux : Due in part to the proximity of the anatomy between the esophagus and heart, acid reflux can produce pain/burning sensation in the mid chest. In your case, however, I would take comfort in that you had a negative stress test. Continue to follow up with your doctor regularly, eat a proper diet and exercise. If you continue to have anxiety over this issue, I'd suggest some counseling.
