The heart is like a never-ending pump, constantly pumping out nutritious blood to various organs through the arteries. If this pump is pumping too much venous blood, in a state of overload for a long time, or if this pump itself has problems for various reasons, or if the resistance of the arteries behind this pump is too high, these conditions will exceed the capacity of the pump after a certain period of time, resulting in a decrease in the function of the pump and a decrease in the volume of blood discharge to meet the needs of the whole body, then the symptoms of heart failure will appear. The main manifestations of heart failure are wheezing and swelling. The shortness of breath is mainly aggravated when going up stairs, climbing hills, walking fast, etc. The patient himself feels that he does not have enough breath and is very tired. Later on, the patient will wake up at night with suffocation, must sit up to relieve, and prefer to sleep on a higher pillow, and finally the patient must sit to sleep, and feel suffocated even while sitting. Edema, on the other hand, is mostly seen in the sagging areas such as the calves, which are depressed, and in severe cases it spreads to the thighs and perineum, and even chest and ascites can occur. Clinically, if a patient with heart disease has typical symptoms of wheezing and swelling, then the possibility of heart failure is high and prompt medical attention is needed, and of course, similar conditions can occur with lung disease. The early clinical manifestations of heart failure are not typical, some patients show fast heartbeat, feel panic and shortness of breath with little activity, feel especially tired after activity, and recover only after a long time of rest; others show that they do not want to eat, or feel bloated and indigested after eating a little more, and patients may even think they are suffering from gastrointestinal diseases and go to the gastroenterology department; in addition, a considerable number of patients will have recurrent In addition, a significant number of patients will have recurrent upper respiratory tract infections, and the treatment effect is not good, when the infusion treatment will be faster and the symptoms of heartburn and wheezing will be aggravated. Heart failure is actually the end stage of various cardiovascular diseases, which has the following characteristics: 1. The average life expectancy of human beings is significantly longer than before, and the survival rate after treatment of various cardiovascular diseases has increased, which has led to an increasing incidence of heart failure and has become a common disease that endangers people’s health. 2. The mortality rate of heart failure is high, close to that of malignant tumors, and can bring about the failure of important organs of the body. In addition, long-term liver stasis can lead to cirrhosis of the liver, with patients experiencing ascites, jaundice, etc. 3. Since heart failure cannot be cured and can only be maintained, patients may need repeated hospitalization and various intubations in severe cases. Patients not only have to bear high medical expenses and physical pain, but also lose hope and cannot cooperate with treatment after a long period of time. In recent years, left ventricular assist device treatment is expensive, and heart transplantation also faces the problems of lack of donor and high cost. In fact, heart failure is a challenge that mankind has not yet conquered.
