Recurrent episodes of pulmonary heart disease can affect a patient’s life expectancy, but how long one can live cannot be generalized; the exact survival time is related to the number of recurrent episodes, the severity of each episode, the treatment method, and the physical condition. Generally speaking, the earlier the disease is detected, diagnosed and treated, the less impact it has on life expectancy. Patients are advised to undergo regular treatment as early as possible. Pulmonary heart disease, referred to as pulmonary heart disease, is a disease in which the structure and/or function of the right ventricle is altered due to respiratory system diseases. Repeated episodes of pulmonary heart disease will cause a decline in pulmonary and cardiac function, thus affecting the patient’s prognosis. Active improvement of the underlying bronchial/pulmonary disease and slowing down of the progression of the underlying disease is needed during the remission period, with the use of asthma-alleviating drugs (e.g., inhaled glucocorticosteroids in combination with long-acting β2 agonists), expectorants (e.g., tranylcypromine) for improvement of the symptoms, home oxygen therapy, pulmonary rehabilitation exercises, smoking cessation, vaccinations, and attention to keeping warm, among other things. Coronary artery disease is a chronic disease that requires early detection and maintenance treatment to slow down the progression of the disease, which is often repeated acute exacerbations due to infections and other factors, and can usually be relieved with treatment. Repeated acute exacerbations will lead to a gradual deterioration of cardiopulmonary function. Patients with pulmonary heart disease need to follow the doctor’s instructions, improve their physical fitness through a reasonable diet and appropriate exercise, and undergo regular review in order to prolong their survival time and improve their quality of life.
