The treatment of heart failure includes bed rest, restriction of physical activity, symptomatic treatment, spironolactone, metoprolol, ivabradine and other medications as prescribed by the doctor, and cardiac resynchronization therapy if necessary. 1. General treatment: such as limiting the patient’s sodium intake and fluid intake. In the acute stage or unstable condition, patients should limit physical activities and take bed rest, while those with stabilized condition can exercise appropriately. 2. Etiologic treatment: Effective treatment of all common diseases that may lead to impaired heart function, such as hypertension, coronary heart disease, diabetes mellitus, etc., to slow down the progression of the disease. 3.Drug treatment (1) Diuretics: commonly used drugs include tachycardia, which can be combined with potassium-preserving diuretics, such as spironolactone. (2) β-receptor antagonists: such as metoprolol, etc. All patients with cardiac insufficiency who are in stable condition and have no contraindications should start applying β-receptor antagonists in small doses. (3) Use of positive inotropic agents: commonly used drugs are digitalis analogs, and systolic heart failure with rapid atrial fibrillation/atrial flutter is the best indication for the application of digitalis. (4) Ivabradine: improve left ventricular function and quality of life. 4. Ineffective drug therapy, cardiac resynchronization therapy can be considered to increase cardiac output by improving atrial, interventricular or intraventricular systolic synchronization, which can improve the symptoms of heart failure and enhance the quality of life. Specifically under the guidance of physicians to choose the appropriate treatment, not blindly use their own drugs.
