Classification of chest pain by nature
The nature of chest pain can be classified as pressure-like pain, pinprick-like pain, dull pain, severe tearing-like pain, colic, burning pain, and severe knife-like pain. Chest pain can be related to breathing, exertion, activity and other factors, and can be continuous pain or paroxysmal pain. Different nature of chest pain generally corresponds to different medical conditions.
1.Posterior sternal pain is mostly associated with coronary artery disease, aortic coarctation, pulmonary embolism, pericarditis and esophageal disorders (such as esophagitis).
2, pleuritic chest pain is most commonly pneumonia, pleurisy, pulmonary embolism; followed by mediastinal disorders and esophageal rupture.
3, chest pain accompanied by abdominal pain, back pain or low back pain seen in aortic coarctation, inferior wall myocardial infarction, pancreatitis.
4, musculoskeletal pain with pressure pain, such as fractures, chest wall soft tissue injuries. However, intra-thoracic disorders may also have superficial pressure pain.
Common emergencies
1, coronary angina, acute myocardial infarction sudden onset of severe and continuous pressure-like pain behind the sternum, with a sense of imminent death. Accompanying symptoms include dizziness, nausea, chest tightness, breath-holding, and cold sweat.
2. tingling, dull pain in the chest on the side of pleurisy, associated with breathing.
3, sudden sharp tearing pain in the chest and back of aortic coarctation with a past history of hypertension.
4, sudden sharp stabbing, tearing pain in the chest with pneumothorax, associated with respiratory distress.
5, intercostal neuralgia burning, stabbing pain in the chest.
6, herpes zoster burning pain and severe knife-like pain in the chest, recent symptoms of cold and fever, chest pain for several days after the discovery of herpes in the chest wall.
7, cardiac neurosis left anterior chest pins and needles-like pain, insomnia, fear of heat.
8. pneumonia chest pain associated with breathing, with fever, cough and sputum.
9. cholecystitis gallstone right lower chest pain associated with diet.
10, chest pain is aggravated by chest trauma on inspiration, related to rib fracture, tension pneumothorax, etc. It can also cause corresponding manifestations such as dyspnea and paradoxical breathing.
Fatal and non-fatal chest pain
Chest pain can be further divided into fatal and non-fatal. Fatal chest pain can quickly become life-threatening and cardiac arrest can occur, which must be promptly resuscitated.
1.Characteristics of fatal chest pain
It is difficult to distinguish acute myocardial infarction from unstable angina based on clinical symptoms alone, and must rely on electrocardiogram and myocardial enzymatic examination to differentiate. If chest pain or chest distress radiates to the shoulder, neck and jaw, it is highly suggestive of this disease. usually accompanied by chest tightness and breath-holding.
(ii) Aortic entrapment whose pain is characterized by sudden pain, anterior-posterior pain, metastatic pain, most painful at onset, and tearing pain.
③Tension pneumothorax progressive worsening of dyspnea after trauma.
2.Characteristics of non-fatal chest pain
There is local pressure pain, pinprick-like pain manifestation, which is aggravated by turning the trunk, breathing and eating.
