Heart failure in the elderly can be categorized into left heart failure, right heart failure and total heart failure. Left heart failure can be manifested by symptoms such as dyspnea, coughing, coughing up sputum, hemoptysis, etc., right heart failure can be manifested by symptoms such as gastrointestinal and hepatic stasis, etc., and total heart failure can be characterized by both right and left heart failure clinical manifestations. Heart failure is a serious stage of heart disease caused by various etiologic factors, with a high mortality rate, and can be divided into left heart failure, right heart failure and total heart failure. 1. Left heart failure: left heart failure is characterized by stagnation of the pulmonary circulation, which may be manifested as dyspnea, cough, sputum, hemoptysis and other discomforts. 2. Right heart failure: right heart failure is dominated by blood stasis in the body circulation. Gastrointestinal stasis may manifest as abdominal distension, lack of appetite, nausea, and vomiting; pulmonary stasis may manifest as dyspnea; and blood stasis in the body circulation may manifest as discomfort such as hydrothorax, ascites, and edema. 3. Total heart failure: the clinical manifestations of both right and left heart failure. Elderly people with heart failure should be reviewed regularly, and if discomfort occurs, they should consult the doctor immediately to avoid delaying the condition.
