<bot>: Hello! Welcome on Chat Doctor! Considering your past medical history for coronary artery disease, I would recommend consulting with your doctor as soon as possible and performing some tests: - a resting ECG and cardiac enzymes- a dobutamine stress echo or a myocardial perfusion cardiac stress test to investigate for the presence of coronary artery disease. If these tests result normal, I would recommend performing a fibrogastroscopy to investigate for the presence of gastritis or esophagitis, which can be related to gastroesophageal reflux. Hope you will find this answer helpful! Wishing good health,
