Many people think that chest pain is a symptom of coronary heart disease, but it is not. Information shows that about one-fifth of patients treated as coronary heart disease in outpatient clinics are misdiagnosed. With plausible symptoms, many young people are diagnosed with myocarditis and older people are diagnosed with coronary artery disease. In fact, chest pain symptoms can occur not only with heart disease, but also with a number of other conditions. Esophageal lesions Information shows that half of the non-cardiac chest pains come from esophageal lesions. Some esophageal pathologies, such as gastroesophageal reflux disease, esophageal hiatal hernia, cardia failure, diffuse esophageal spasm and esophageal cancer, can cause chest pain, among which gastroesophageal reflux disease is the most common. Gastroesophageal reflux disease manifests as burning pain below or behind the sternum, which occurs after eating or worsens when eating. The clinical characteristics of chest pain caused by esophageal disease are very similar to those of cardiogenic chest pain, but chest pain caused by esophageal disease is usually related to eating and accompanied by some gastrointestinal symptoms. 1, cardiac neurosis The disease is common in middle-aged or menopausal women. Its manifestation is chest tightness or chest pain, and the pain is mostly a little, a line, a small piece or symmetrical pain in the front and back of the chest, which lasts for several hours or a whole day, and feels comfortable only after a long sigh. Most of the patients have symptoms such as heartburn, palpitations, sweating, insomnia, etc.; they feel upset and stuffy in crowded places, and feel comfortable only after they go outside or open the window. Chest pain attacks are often related to emotional tension, mental stress, overexertion and other factors. 2, chest wall itself diseases such as costal cartilage osteochondritis, often occurring in the 2nd to 4th rib cartilage and quarter rib section (the lower front edge of the rib cage). Local pain and pressure are often present, the onset of swollen and elevated rib cartilage, and pain can increase with deep breathing, coughing and upper limb movement. If the chest pain is in electroshock-like paroxysms, it may be intercostal neuralgia. If the chest pain is confined to the intercostal area and is accompanied by skin irritation, it is often an early manifestation of herpes zoster. 3.Respiratory system diseases Acute bronchitis or bronchopneumonia, in addition to cough and sputum, is often accompanied by a feeling of urgency or pain behind the sternum. If the chest pain worsens with breathing or coughing, and the pain is confined to one side of the chest, it is mostly pleurisy. If the pain in the chest is persistent, accompanied by dry cough and occasionally blood in the sputum, it is more likely to be lung cancer. Middle-aged and elderly people who suffer from chronic bronchitis, emphysema or tuberculosis and suddenly feel severe chest pain, shortness of breath, pallor and sweating without any aura should be considered as spontaneous pneumothorax. For some patients who have been bedridden for a long time, or have a history of lower limb vein thrombosis, pelvic surgery and lower limb vein surgery, if they suddenly develop chest pain with hemoptysis and dyspnea, the possibility of pulmonary embolism should be considered. 4, cervical spondylosis Some patients with cervical spondylosis may also develop palpitations, chest tightness, episodic precordial pain with dizziness, which is called cervical heart syndrome. (1) Patients with cervical heart syndrome often have a history of long-term ambulatory work, or have the bad habit of sitting or lying in bed watching TV for a long time. (2) The episodes of anterior heart pain caused by cervical spondylosis last for a long time, usually lasting 1 to 2 hours. (3) No significant effect of taking anti-anginal drugs. (4) Artificial compression of the paracervical pressure zone can induce chest pain. (5) After receiving cervical spine treatment, such as massage and physical therapy, the duration and number of episodes of precordial pain can be effectively reduced.
