In many cases, patients develop heart failure, the final stage, due to ineffective and timely treatment of underlying heart diseases such as various coronary heart diseases, hypertension, and arrhythmias.

[0003] Heart failure is the terminal stage of various heart diseases. Typical symptoms of heart failure include dyspnea, lower limb edema, liver enlargement (hepatic congestion), and abdominal swelling (gastrointestinal congestion). Due to its poor prognosis and frequent deterioration of the condition, patients are at high risk of rehospitalization, which seriously affects their normal lives. Heart failure patients typically have increased lung water capacity. Quantitative lung water monitoring and assessment of heart failure patients can enable early and effective intervention to reduce the risk of rehospitalization.
