Wheezing is a typical manifestation of bronchial asthma, especially during acute attacks, but because asthma is a chronic inflammatory disease of the airways, there is airway hyperresponsiveness and variable airflow limitation, during the non-acute attacks of asthma, there are also often symptoms, including: cough, chest tightness and breathlessness, chest pain, activity intolerance, and easy fatigue, so if these manifestations occur, and may be symptoms of asthma, indicating that asthma is not fully controlled, rather than other diseases. Especially if chest tightness is the main manifestation, it cannot be treated according to myocarditis. Therefore, it is important for patients to give a good account of their past medical history to the doctor during the consultation.
