The gold standard for the diagnosis of pulmonary hypertension is the right heart floatation catheterization, and a value of 25-35mmHg can be diagnosed as mild pulmonary hypertension.
Right heart floatation catheterization is a minimally invasive test under local anesthesia, which can measure the patient’s pulmonary artery pressure, ≥25mmHg can be diagnosed as pulmonary arterial hypertension. between 25-35mmHg is mild pulmonary arterial hypertension, 35-45mmHg is moderate pulmonary arterial hypertension, ≥45mmHg is severe pulmonary arterial hypertension.
In addition to the gold standard of the right heart floating catheter, it can also be clinically estimated by cardiac ultrasound. Pulmonary hypertension is an increase in the pressure of the blood circulation in the lungs, which can cause abnormalities in the function of the lungs, affecting the gas exchange of the lungs, and clinically there will be dyspnea. However, mild pulmonary hypertension usually has no obvious clinical symptoms, and it is recommended to be evaluated by a professional physician to avoid any misunderstanding of the condition.
