Today we talk about how to prevent pulmonary heart disease? How should pulmonary heart disease be prevented? First of all, we need to allow patients to enhance the low body resistance. The repeated infections and inflammation of patients are caused by poor resistance, so we can not only let patients participate in outdoor sports and open windows regularly, but also take or inject drugs to improve resistance when the seasons change. You can also take sea cucumber 2 to 3 times a week during the day.

According to the actual symptoms of the patient, appropriate nebulized inhalation of drugs to calm asthma, resolve phlegm and improve airway spasm can be applied. If there are no obvious symptoms, you can also take water for nebulization. In order to prevent further expansion of the heart, the clinical application of drugs to prevent the progression of heart failure can often be chosen, at present, the main advocate of the golden triangle of drugs, including beta-blockers, aldosterone receptor antagonists, ACEI/ARB drugs. beta-blockers often have a certain effect on the airway, for patients with severe pulmonary heart disease, try to avoid the use, can apply ivabradine Alternative therapy is available. Pulmonary heart disease, both prevention and treatment, is a constant battle that requires patients to be careful in their daily routine and to take drugs with secondary prevention effects on time.
