Commonly used drugs for chronic heart failure in the elderly are diuretics, angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor antagonists (ARB), aldosterone receptor antagonists, digitalis drugs and so on. 1. Diuretics: can discharge excess water through diuresis, reduce blood volume, reduce cardiac preload, reduce myocardial oxygen consumption, and at the same time reduce pulmonary edema and peripheral edema, which is conducive to relieving dyspnea. 2. ACEI: dilates blood vessels, reduces cardiac afterload, and also regulates neuroendocrine abnormalities, reversing myocardial remodeling to a certain extent. 3. ARB: It can improve abnormal hemodynamics, reduce cardiac pre and post load, reverse cardiomyocyte hypertrophy, and reduce interstitial myocardial fibrosis. 4. Aldosterone receptor antagonist: it can inhibit the role of aldosterone in promoting vascular and myocardial fibrosis, as well as excitation of sympathetic nerves, and improve cardiac function. 5. Digitalis drugs: mainly play a positive inotropic effect, while reducing the activity of the neuroendocrine system to play a role in the treatment of heart failure. Chronic heart failure patients, in addition to drug therapy, but also timely removal of triggers, such as infection, anemia, arrhythmia, etc., diet to reduce the intake of water and sodium, but also pay attention to rest and appropriate exercise.
