The presence of chest tightness and shortness of breath when speaking suggests a decline in respiratory function, indicating varying degrees of severely impaired ventilatory and ventilatory function. More common clinically are respiratory disorders, such as persistent states of wheezing bronchitis and bronchial asthma that can be severe. Due to the instability of airway airflow stimulated by speaking, the relatively severe airway hyperresponsiveness state itself becomes more pronounced, the airway mucosa becomes significantly congested and edematous, and the bronchial smooth muscle becomes significantly contracted and spasmodic, leading to symptoms of chest tightness and shortness of breath from speaking. Clinically, it is also seen in cardiovascular system diseases, such as more severe left heart failure causing acute pulmonary edema, when cardiac function decreases and can reach class III or even class IV cardiac function, while leading to telangiectatic breathing, and even slight activity of speech can lead to symptoms of dyspnea with chest tightness and shortness of breath.
