The causes of stomach pain and heart pain include gastritis, cholecystitis and angina. 1. Gastritis: due to the inflammation constantly stimulating the gastric mucosa, causing excessive secretion of gastric acid, triggering the symptoms of stomach pain. As the stomach and the heart are located relatively close to each other, when severe pain occurs in the stomach, the heart will be involved in the symptoms of discomfort, such as chest pain, palpitations, panic, and so on. 2. Cholecystitis: Due to the inflammation and infection in the gallbladder, the inflammatory factor constantly stimulates and triggers patients to experience pain in the upper abdomen. When the patient’s pain intensifies, radiating pain will appear, such as stomach pain, heart pain, back pain, etc. 3. Angina: due to insufficient blood supply to the coronary arteries, it triggers ischemia and hypoxia of the cardiomyocytes, and the symptoms of angina appear. When angina pectoris attacks, there may be radiating pain to the stomach, precordial area, back and other parts of the body, leading to the emergence of symptoms of stomach pain and heart pain in patients. When the patient has stomach pain and heart pain symptoms, it is recommended that the patient go to the hospital in time to improve the gastroscopy, electrocardiogram, ultrasound and other tests, to clarify the cause of the disease, and follow the doctor’s instructions for treatment, so as to avoid adverse consequences.
