Novel Coronavirus Pneumonia is a respiratory disease, mainly characterized by respiratory symptoms. Patients may present with cough, fever, chest tightness, dyspnea, uncorrectable respiratory acidosis, and even coagulation disorders. Chest tightness is one of the manifestations of novel coronavirus pneumonia, but not all chest tightness is novel coronavirus pneumonia. Chest tightness can be a manifestation of cardiopulmonary disease, or it can be a result of poor air circulation, such as chest tightness that can also occur with anger and bad mood. Chest tightness can occur with a bad throat, heart disease, and respiratory diseases such as chronic bronchitis and asthma. When determining novel coronavirus pneumonia, be sure to consider its gold indicators: novel coronavirus nucleic acid testing, a history of lung inflammation, exposure in an infected area, or a history of exposure to a patient with novel coronavirus pneumonia.
