Cor pulmonale

Cor pulmonale, also known as pulmonary heart disease, is a condition where increased pulmonary vascular resistance due to bronchial, pulmonary, thoracic, or pulmonary vascular lesions leads to pulmonary hypertension, ultimately causing changes in cardiac structure or function. The main symptoms of cor pulmonale include cough, dyspnea, weakness, and fatigue. As the disease progresses, respiratory failure and heart failure may occur.
