EpistemisDiffuse painless chest tightness
Specialty: Respiratory.
Why it occurs
- Bronchial asthma in the prodromal phase or mild to moderate exacerbation (bronchoconstriction of small airways is initially perceived as a sensation of oppression or tightness due to the stretching of rapidly adapting bronchial receptors, before the appearance of audible wheezing)
- Acute hypersensitivity pneumonitis (exposure to allergens causing diffuse alveolar inflammation and transient lung stiffness)
- Chronic obstructive pulmonary disease (COPD) with dynamic hyperinflation induced by physical exertion (air trapping that limits normal thoracic excursion)
- Laryngeal or bronchial angioedema in the initial phase of an anaphylactic reaction
- Environmental exposure to allergens or high-density air pollutants.
Initial workup
Forced spirometry with bronchodilator reversibility test; Maximum expiratory flow monitoring (Peak Flow); Chest x-ray; Blood analysis with complete blood count to evaluate eosinophilia or total IgE; Bronchial challenge test with exercise or methacholine if initial spirometry is normal.
red flags
Oppression accompanied by audible wheezing at a distance, dyspnea that prevents ambulation, labial cyanosis, persistent diaphoresis, arterial hypotension, or concomitant inspiratory stridor that suggests compromise of the upper airway.
Standard management
- Salbutamol — 100-200 micrograms inhaled through the inhalation chamber, repeat every 20 minutes according to response in the rescue phase
- IPratropium bromide — 20-40 micrograms inhaled every 6-8 hours
- Prednisone (20-40 mg orally daily for 3-5 days if progression to moderate asthma attacks is confirmed).
