Heart failure is relatively common in clinical settings, primarily divided into left heart failure, right heart failure, and global heart failure. The clinical manifestations of left heart failure are mainly reflected in symptoms of pulmonary congestion. It can present as varying degrees of dyspnea, cough, expectoration, palpitations, and fatigue. Right heart failure is mainly due to obstruction of the inferior vena cava flow, leading to increased venous pressure and capillary pressure. This causes plasma components to extravasate and ultimately leads to the formation of ascites. Global heart failure includes the symptoms of both left and right heart failure. Therefore, it is essential to seek medical attention promptly after heart failure occurs.
