The right ventricle is the volume organ that receives venous blood flow throughout the body, so the earliest manifestations of right heart failure are the symptoms caused by stasis of blood in the organs of the body.1. Gastrointestinal manifestations, such as abdominal distension, poor appetite, nausea and vomiting.2. Patients with right heart failure may have exertional dyspnea in the early stage, and for patients with ascites or large liver, because ascites or enlarged liver elevates the diaphragm and reduces the chest cavity, patients will show shortness of breath and suffocation.3. The earliest sign of right heart failure is edema, mainly swelling of the lower limbs, which is caused by increased venous pressure and reduced return blood volume, resulting in edema in the surrounding tissues and organs, and symmetrical, depressed edema in the low hanging parts of the body, The cause of right heart failure should be identified and treated promptly with diuretics and drugs to increase myocardial contractility.
