Currently, there is no better way to treat heart failure. It is only treated with medications. Clinical drugs include diuretics, angiotensin, and other medications. Patients must take medications strictly as prescribed by the doctor and should not stop taking the drugs, reduce the dosage, or change the medications without permission to avoid serious adverse consequences. When taking digitalis medications, attention should be paid to toxic reactions. If there are conditions such as bacterial infections or pulmonary infections, anti - infective treatment should be carried out first because the main inducement for heart failure in the elderly is often caused by infections. In daily life, it is essential to reduce water intake, which can effectively prevent water and sodium retention. During the treatment period, patients should pay attention to rest, avoid staying up late, ensure adequate sleep, keep a happy mood, combine work with rest, and avoid over - exertion. Therefore, elderly patients with heart failure must go to the hospital in time to avoid delaying the condition. The prognosis of heart failure is relatively poor.
