Gastro-cardiac syndrome is mainly a series of digestive system diseases caused by stomach diseases, such as gastric and duodenal bulb ulcers, chronic gastritis, gastric dilatation, gastric mucosal prolapse, peptic ulcer, and posterior gastric wall perforation. The pain in the precordial area refers to the functional disorder of the cardiovascular system reflexively caused by stomach diseases. It is more common in young people, and the incidence is similar between men and women. Its common symptoms are mainly discomfort or dull pain in the precordial area, or angina pectoris accompanied by chest tightness and shortness of breath. The cardiovascular symptoms disappear with the cure of the stomach diseases. This condition is easily confused with heart diseases, and attention should be paid to the differentiation.
