What is cor pulmonale?
Pulmonary heart disease is the abbreviation of pulmonary heart disease, which is caused by chronic diseases of lung, bronchus or pulmonary vessels. Under normal circumstances, the development of primary diseases of lung tissue or pulmonary artery and its branches increases the resistance of pulmonary blood circulation and causes the pressure in pulmonary artery to increase. In this way, the resistance of the right ventricle to deliver blood to the lungs increases, which leads to the hypertrophy and enlargement of the right ventricle with the progress of the disease. Such patients often have symptoms of right ventricular dysfunction such as edema of lower limbs, hepatomegaly, palpitation, shortness of breath and loss of appetite.

Generally speaking, cor pulmonale is a chronic disease and a common disease that seriously endangers human health. In the late middle age, the incidence rate is higher. There are many ways to treat cor pulmonale, but basically it is to maintain the existing symptoms. Pulmonary heart disease is difficult to cure. In recent years, the treatment of cor pulmonale has made rapid progress, but the mortality rate is still high. Therefore, it is particularly important to prevent cor pulmonale.
