[0002] Heart failure, also known as HF, refers to the inability to fully discharge venous blood from the heart due to the systolic and / or diastolic function of the heart, which leads to blood congestion in the venous system and insufficient blood perfusion in the arterial system, thus causing a syndrome of cardiac circulatory disorders. This syndrome mainly manifests as pulmonary congestion and vena cava congestion. Heart failure is not an independent disease, but the terminal stage of heart disease. The vast majority of heart failures start with left heart failure, which first manifests as pulmonary circulation congestion.
