The treatment of CHF in the elderly should first emphasize general treatment, including etiological treatment, removal of triggers, diet and rest. The causes of CHF in the elderly are hypertension, coronary heart disease, pulmonary heart disease, arrhythmia, anemia, etc., which must be well controlled in order to reduce the symptoms of CHF, and in the elderly, due to reduced physiological function and low cardiac reserve capacity, there are often minor triggers that can lead to the occurrence or aggravation of CHF, such as emotional stimulation, climate change, urinary retention, etc. are common triggers that lead to CHF in the elderly. The most common triggers are infections, which must be avoided and corrected as much as possible. Diet and rest are also very important parts of general treatment, and improving lifestyle is a very important aspect of prevention and treatment of CHF in the elderly, including smoking cessation, alcohol cessation, weight reduction, and low sodium and low fat diet. Patients with severe CHF should also limit their water intake and maintain a relative balance of intake and output. patients with CHF should still engage in appropriate exercise to improve cardiac endurance and also to avoid thromboembolic disease brought on by long-term inactivity, etc. The definite pharmacological treatments for CHF in the elderly are diuretics, ACE inhibitors, digitalis preparations and beta-receptor antagonists, and the choice of drugs for CHF in the elderly must be individualized and systemic. (1) Diuretics: All CHF patients with evidence of fluid retention or those who have had fluid retention should be given diuretics. The elderly are prone to adverse effects such as electrolyte imbalance, blood pressure drop, renal insufficiency, cerebral insufficiency and even thrombosis after the application of diuretics due to various physiological compensatory functions and reduction of total body fluids, which must be taken seriously. Therefore, the application of diuretics for the elderly must start with a small dose and gradually increase the dose. The appropriate dose should be the initial weight reduction of the patient at 0.5-1.0 kg, and then reduce the dose and maintain the medication after the condition is stabilized. Commonly used drugs are hydrochlorothiazide and furosemide. To reduce the degree of electrolyte disorders, potassium-protecting diuretics such as anisodone and aminoglutethimide can be added at the same time, and blood biochemical indicators should be monitored frequently. (2) ACE inhibitors: ACE inhibitors can be beneficial in the treatment of CHF by inhibiting the renin angiotensin system (RAS) and acting on kinase II to inhibit the degradation of bradykinin and increase bradykinin levels. It should be used indefinitely for life in all patients with systolic CHF, unless contraindicated or intolerable. ACE inhibitors must be used with caution in cases of bilateral renal artery stenosis. Significantly elevated creatinine levels. The application of ACE inhibitors should also start with a small dose, and if tolerated, the dose should be doubled every 3-7 days until the maximum tolerated amount and then applied for a long time. (3) β-receptor antagonists: excessive activation of the adrenergic receptor pathway can have toxic effects on the heart. Therefore, it is recommended that all NYHA class II and III patients with stable disease and LvEF < 40% should be treated with β-blockers early, unless contraindicated or intolerable. However, β-blockers are powerful negative inotropic agents that can inhibit cardiac function at the beginning of treatment and improve cardiac function only after long-term treatment (>3 months). Therefore, β-blockers are generally not used in patients with unstable or severe CHF and should not be used to “rescue” patients with acute HF, including refractory CHF. most elderly people have poor cardiac reserve capacity and are often sensitive to β-blockers, so the application must start with small doses and gradually increase the dose under close monitoring. (4) Application of digitalis: The treatment of HF with digitalis preparations has been confirmed for a long time, and it can also be applied in elderly people with HF, but elderly people often have renal insufficiency and electrolyte imbalance, etc., which are less tolerable. (5) Other drugs: such as aldosterone antagonists, angiotensin II receptor antagonists, etc., are also considered to be beneficial in CHF, but further efficacy is still under study.
