There are more causes of precordial pain, which may include heart disease, esophageal diseases, respiratory diseases and psychosomatic factors, etc. Common causes include coronary heart disease and gastroesophageal reflux disease. The diseases that may be associated with precordial pain are as follows: 1. Cardiovascular system diseases: coronary heart disease can cause myocardial ischemia and hypoxia, causing pain in the precordial region. Coronary heart disease is related to exertion and emotional excitement, and mainly includes angina pectoris, infarction and other types. If it is angina, rest or nitroglycerin containing can be relieved. Coronary artery disease is more likely if the patient has previous hypertension, diabetes, and hyperlipidemia. Cardiac enzymes, troponin, electrocardiogram, echocardiogram, coronary CT, cardiac MRI or coronary angiogram can be used to clearly exclude heart disease problems. 2, digestive system diseases: gastroesophageal reflux disease causing pain in the precordial region is more common. Gastroesophageal reflux disease occurs when the reflux stimulates the esophagus and can cause chest pain, sometimes similar to angina pectoris. It may be accompanied by reflux and a feeling of heartburn. Digestive system disorders are affected by eating and antacid therapy. It can be clarified by gastrointestinal endoscopy. When anterior cardiac pain is detected, cardiovascular disease must first be ruled out, as heart attacks can be fatal if not treated promptly. Regardless of the condition causing precordial pain, the patient needs to be seen as soon as possible to rule out critical illnesses.
