If tuberculosis can be diagnosed in time and treated actively, most of them can be cured without sequelae. However, in some patients, due to the progression of the disease involving the heart and lungs and other organs, symptoms such as cough, dyspnea, shortness of breath, chest tightness and other sequelae may remain after the cure of pulmonary tuberculosis. Tuberculosis is a respiratory infectious disease that occurs in the lung tissues, trachea, bronchus and pleura caused by Mycobacterium tuberculosis infection. Patients may experience symptoms such as cough, coughing, blood in sputum, low-grade fever, malaise, and night sweats (abnormal sweating after going to sleep and stopping after waking up). Generally, the prognosis is good through timely treatment with anti-tuberculosis drugs, which may leave fibrous streaks or calcified foci in the lungs. Some patients may develop chronic pulmonary heart disease and heart failure at a later stage, then the prognosis is poor, and they may be prone to coughing, dyspnea, shortness of breath and other sequelae after TB is cured. When the tuberculosis lesion spreads to the pleura, it may cause chest tightness, chest pain and other sequelae. It is recommended that patients with tuberculosis be detected, diagnosed and treated early to improve the prognosis of the disease and reduce the occurrence of sequelae.
