[A study on pulmonary artery compliance and hemodynamics in patients with lung-distention]

A simultaneously comparative study on pulmonary artery compliance (Cpa) and pulmonary artery mean pressure (PAMP) in 89 patients with Lung-Distention in TCM by impedance pulmonary rheogram, tricuspid valve echocardiogram and right heart catheterization. Then according to Syndrome Differentiation of TCM, Lung-Distention was sub-divided into four groups. The results showed that PAMP were gradually increased and Cpa decreased in these groups. It revealed that the pulmonary circulation of Lung-Distention patients has disturbed.
