If a patient often has a burning sensation in the chest, the first thing to do is to rule out heart and digestive tract diseases. Diseases of the heart mainly refer to such people as coronary heart disease and angina pectoris. Due to the narrowing of one or more blood vessels in the heart, when the narrowing exceeds 70%, the manifestation of myocardial ischemia will occur, which is especially obvious after activity. Patients will suddenly experience pain and burning sensation in the chest for less than 5 minutes, not more than 15 minutes, and not more than half an hour, which can be quickly improved after resting or stopping exercise. If you take nitroglycerin or quick-acting heart pills orally, the pain will disappear more quickly and will return to normal after about 1-2 minutes. An electrocardiogram can reveal partial ST-T changes in the heart, and a coronary CT or coronary angiogram can clarify the location and extent of the narrowed vessels in the heart. Gastrointestinal diseases, mainly include ulcers of the gastrointestinal tract and esophageal reflux gastritis. If the patient has esophageal reflux gastritis, this burning sensation is more pronounced when lying down. Patients with gastric ulcers or duodenal ulcers will experience pain before or after meals. For duodenal ulcers, the pain is predominantly on an empty stomach before meals. For gastric ulcers, pain after meals or after a full stomach is predominant.
