Elderly patients with heart failure need to be given systematic treatment, including treatment of the causative factors, treatment of the etiology, and treatment of the heart failure state, which for the treatment of the causative factors, including upper respiratory tract infections and digestive tract infections, can cause the occurrence of heart failure. In addition, too much water and too many fluids can also cause heart failure, so it is important to keep warm and to pay attention to a dry and clean diet. For the treatment of the cause of heart failure, including all types of organic heart disease, systematic treatment is needed. The treatment of heart failure, including diuretics, is the basic treatment, and care should be taken to avoid electrolyte disturbances. The treatment of renin-angiotensin system inhibitors can improve the symptoms and prognosis, and beta-blockers can play the role of anti-arrhythmia and improve the prognosis. If necessary, the application of combined cardiotonic drugs, such as digitalis, is needed.
