title: Chest pain relieved with a bronchodilator or other asthma drugs.
abstract: BACKGROUND
  Although many patients who experience chest pain or pressure consult their physicians, unfortunately a large number of them do not, and consequently they remain undiagnosed and untreated. Chest pain, in a subset of these patients, may be relieved with a bronchodilator or other asthma drugs.
  
  
  METHODS
  This retrospective study included twenty cases of chest pain that were relieved with asthma drugs. Chest pain was categorized into three types: chest pain variant asthma, bronchial asthma with chest pain, and non-asthmatic allergic chest pain. Chest pain variant asthma was defined as chest pressure that improved in response to a bronchodilator, without the characteristic attacks of bronchial asthma. Bronchial asthma with chest pain was defined as chest pressure, with the characteristic attacks of bronchial asthma that improved following the administration of a leukotriene receptor antagonist, systemic corticosteroid, or bronchodilator. Non-asthmatic allergic chest pain was defined as chest pressure without the typical asthma attack, but with chest pressure that improved in response to a leukotriene receptor antagonist or systemic corticosteroid, but not a bronchodilator.
  
  
  RESULTS
  Fourteen cases of chest pain were diagnosed as variant asthma, three cases were diagnosed as bronchial asthma with chest pain, and three cases were diagnosed as non-asthmatic allergic chest pain.
  
  
  CONCLUSIONS
  The results suggest that the mechanism underlying chest pain that is relieved with asthma drugs can involve either an airway constriction pathway or a non-constrictive pathway presumably airway inflammation. Analysis of the patient's response to treatment with asthma medication is useful for the correct diagnosis of the source of chest pain.
