What is the normal value of pulmonary hypertension?

summary

Of course, we should pay attention to the normal value of pulmonary hypertension, because if the pulmonary hypertension exceeds the standard value, it will pose a great threat to health, and also lead to congenital heart disease and more serious complications. The pulmonary artery pressure of normal people is 15-30 / 5-10mmhg, with an average of 15 mmHg. Let's share the normal value of pulmonary hypertension?.

What is the normal value of pulmonary hypertension?

First, the pulmonary artery pressure of normal people is 15-30 / 5-10 mmHg, with an average of 15 mmHg.

Second, if the systolic pressure of pulmonary artery is more than 30 mmHg, or the mean pressure is more than 20 mmHg, it is pulmonary hypertension.

Third: who regulations: pulmonary artery systolic pressure ＞ 25 mmHg at rest and pulmonary artery pressure ＞ 30 mmHg during exercise are pulmonary hypertension.

matters needing attention

Stage I (Grade A): abnormal muscle tissue spread into peripheral arterioles and mild thickening of normal muscular vessels, which was less than 1.5 times of normal. This change is due to the neogenesis and hypertrophy of smooth muscle induced by chronic high blood flow and high pressure. Stage II (Grade B): further growth and hypertrophy of muscle tissue: in stage II, the thickness of middle wall was 1.5-2 times of normal, and the pulmonary artery pressure had increased. In the second stage, the middle wall thickness was more than 2 times of the normal, and the pulmonary artery pressure was half of the systemic circulation pressure. The vascular wall was thickened by hypertrophy of myocytes, proliferation of myocytes and increase of extracellular matrix protein.
