Abstract
Cor pulmonale refers to hypertrophy and (or) dilatation of the right ventricle due to diseases that affect the structure or function of the lungs, or both at the same time. Chronic cor pulmonale occurs with lesions of the bronchopulmonary system (chronic bronchitis, bronchial asthma, pulmonary emphysema, pulmonary tuberculosis, etc.), impaired mobility of the chest (kyphoscoliosis, Bechterew's disease, pleural folds, obesity, etc.) and diseases of the pulmonary artery system (repeated thromboembolism, primary pulmonary hypertension, lung resection, etc.). Right ventricular hypertrophy and insufficiency also occur with secondary changes in the lungs in patients with diseases of the left heart (cardiosclerosis of various etiologies, mitral stenosis) and congenital heart defects, but these cases do not apply to cor pulmonale. Most often, cor pulmonale develops in diseases of the bronchopulmonary system.
