Reduced exercise tolerance
Introduction
Introduction Chronic obstructive pulmonary disease (COPD) and diffuse interstitial lung disease (ILD) have prominent clinical manifestations of shortness of breath and decreased exercise tolerance [1, 2], and the quality of life of patients is seriously affected. Decreased general endurance, exertional dyspnea and fatigue are important complaints for patients with congestive heart failure. The difficulty of breathing and the reduction of maximum oxygen consumption caused by pulmonary congestion during heart failure are the reasons for their decreased exercise tolerance. There may also be hypothyroidism in the elderly or alveolar proteinosis in children.

A decrease in exercise tolerance is likely to result in chronic obstructive pulmonary disease (COPD) or diffuse interstitial lung disease (ILD). It is characterized by decreased general endurance, exertion of dyspnea and fatigue.
Diagnosis
Differential diagnosis
1. Chronic Obstructive Pulmonary Disease (COPD):
Chronic chronic lung disease characterized by incomplete reversible airflow limitation, airflow limitation is not completely reversible, progressive development, and is associated with abnormal inflammatory response of the lungs to harmful gases or harmful particles.
2. Diffuse interstitial lung disease is a large heterogeneous disease with similar clinical, imaging and pulmonary functions. Pathological changes mainly occur in the alveolar interstitial structure, and may also involve bronchioles and pulmonary vessels. Cough and exertional dyspnea are the most common symptoms, usually occurring slowly, but progressively worse. Most manifested as dry cough, hemoptysis is rare, LAM, AIP, EAA, drug pneumonia, COP and pulmonary eosinophilia are sometimes accompanied by fever and other systemic symptoms. Chest pain is rare; acute pleural pain caused by pneumothorax is one of the clinical manifestations of histiocytosis X and LAM. Some patients may have no symptoms, only accidentally found during chest imaging studies for other reasons.
