Hi, was the coronary angiography normal? If this study is normal, then you can be sure that the blood supply to the heart is good and that you don't need any medications. The pain could be due to other causes like GERD, (Gastro Esophageal Reflux Disease), where the acid contents of the stomach come up into the esophagus. You can try lifestyle measures and see if it helps with the pain. Take frequent small meals. Eat dinner about two hours before sleeping. Elevate the head end of the bed. Keep a food diary and note down what aggravates your symptoms and avoid them. Ensure to maintain optimum weight by regular exercise. Avoid non steroidal anti inflammatory medications NSAIDs, quit smoking, eliminate alcohol and reduce stress levels. These measures need to be practiced long term for results. Hope this helps!!
