Cor pulmonale is a disease in which respiratory conditions, including diseases of the bronchial-lung tissue and thoracic or pulmonary vascular diseases, cause changes to the right ventricle's structure and function. The disease is mostly derived from the chronic bronchial disease. It will cause the lung of the patient to be affected by long-term pulmonary vascular obstruction, resulting in a gradual increase in arterial pressure in the lungs and the ventricular load on the ventricle increases.
