The principle of treatment for chronic pulmonary heart disease is to actively remove the causes of exacerbation, control respiratory failure, and control heart failure. 1. Remove the triggering causes of exacerbation: Respiratory infections may be the cause of exacerbation of chronic pulmonary heart disease, if there are infections, it is necessary to actively control the infection. 2. Control respiratory failure: respiratory failure should be corrected in time to reduce the burden on the heart. Expectorant treatment, bronchial dilatation can be considered to improve the ventilation function and unobstructed airway. 3. Control heart failure: for chronic pulmonary heart disease, heart failure can be relieved by improving respiratory function, actively controlling infection and correcting hypoxia. If the effect is not obvious, small doses of diuretics, such as hydrochlorothiazide and spironolactone, can be used. The treatment of chronic pulmonary heart disease needs to be timely, usually through the above treatment can improve the condition, but need to be treated in a regular hospital.
