Gastrocardiac syndrome is associated with phytonadic dysfunction, and can be caused by any disease of the stomach. Common causes include peptic ulcer, chronic gastritis, gastric mucosal prolapse, smoking, etc. Most of the cardiac examinations in this disease have no abnormal findings, most of the electrocardiograms are often normal, a few have ST-T changes and arrhythmias, which can sometimes be misdiagnosed as angina pectoris or acute myocardial infarction. If the symptoms of cardiovascular system appear on the basis of the original chronic gastric disease, the diagnosis of this disease can be made when the organic cardiovascular pathology is excluded. Sometimes the patient’s gastric symptoms are not obvious, and those who present with cardiovascular symptoms alone are prone to misdiagnosis, so the awareness of this disease should be improved. If it is not well explained by cardiovascular disease, relevant gastrointestinal examinations, such as X-ray and gastroscopy, should be performed to confirm the diagnosis. In gastrocardiac syndrome, the use of coronary dilation drugs is not effective, but the application of antispasmodic and antacid drugs can be relieved, and cardiovascular symptoms disappear with the cure of gastric disease. The treatment of this disease is mainly for the treatment of the original disease of the stomach, quit smoking and alcohol, to relieve pain can be applied to antispasmodic and antacid drugs, such as baking soda, cholinergic inhibitors, H2 receptor blockers or proton pump inhibitors.
