Heart failure (heart failure) refers to heart failure, which is a symptom of heart circulatory disturbance, such as pulmonary congestion and vena cava congestion, caused by failure of the systolic function and/or diastolic function of the heart to sufficiently discharge venous blood back to the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system. An intra-aortic balloon counterpulsation system (IABP) is an effective means for treating heart failure, and is characterized in that a balloon counterpulsation catheter is placed at the aortic position of a patient through arterial puncture, and when the aortic valve is closed at the initial stage of diastole, a counterpulsation pump is used for inflating the balloon to enable the balloon to be inflated, so that positive pressure is generated, the diastolic pressure is increased, and the blood perfusion of the whole body and the coronary arteries is increased; when the aortic valve is opened in the heart ejection period (i.e. systole), the saccule is rapidly emptied and deflated to generate negative pressure, so that the aortic pressure is instantaneously reduced, the heart left ventricular ejection resistance, namely heart afterload, is reduced, the heart ejection volume is increased, and the left ventricular ejection is improved.
