The treatment of heart failure mainly includes the following points. The first major category is etiological treatment, where we should actively manage all common diseases that may impair cardiac function, such as hypertension, coronary heart disease, diabetes, etc. The second category is to eliminate the factors that lead to heart failure, such as infections, especially respiratory infections. The third major category is for patients to pay attention to rest, control physical activity, avoid emotional excitement, and control sodium intake to reduce blood volume. The fourth category is drug therapy, which commonly includes the use of diuretics, ACE inhibitors, positive inotropic drugs, and β-blockers in clinical practice. (Medication should be administered under the guidance of a doctor.)
