Gastritis typically does not cause chest pain. However, if patients with chronic gastritis experience chest pain, it is important to pay attention to whether it is accompanied by chest tightness or difficulty breathing. If such symptoms are present, one must be alert to the possibility of heart disease or respiratory system disorders, and seek medical attention promptly. Based on relevant medical history and clinical symptoms, a physical examination should be conducted, followed by appropriate diagnostic tests. These may include chest X - rays, chest CT scans, electrocardiograms (ECG), echocardiograms, and endoscopy to establish a clear diagnosis. Additionally, targeted and proper treatment should be administered accordingly.
