Chest burning like fire is likely to be caused by digestive system diseases, generally peptic ulcer, reflux esophagitis can reflexively cause chest pain or burning sensation behind the sternum. In such cases, gastrointestinal imaging and electronic gastroscopy can be performed to clarify the presence of esophagitis, peptic ulcer and other diseases, and such diseases can be referred to gastroenterology to promote gastric motility and control the application of acid-suppressive drugs. In addition, coronary heart disease and angina pectoris also have a burning sensation in the sternum. If the patient is old, coronary heart disease should be ruled out, and if necessary, coronary angiography and cardiac CT examination should be performed in the cardiology department to clarify the diagnosis, and then oral aspirin, betalactone, nitroglycerin and other medications should be given after the clear diagnosis.
