肺心病患者脑循环动力学的研究

摘要

Objective To investigate cerebrovascular activity (CVA) change of pulmonary heart disease patients.Methods To measure CAV of acute stage and compare with CAV of remission stage and control group with CAV tester.Results Average cerebral blood flow velocity,maximal blood velocity,minimal blood velocity and minimal blood flow of pulmonary heart disease patients decrease apparently (P< 0.01);peripheral resistance,characteristic impedance,wave velocity of elastic wave and dynamic impedance increase apparently( P< 0.01) ;average blood flow decrease apparently,critical pressure increase apparently( P< 0.05) ;there is no difference in vascular compliance and maximal blood flow between two groups (P>0.05).Conclusion CVA of pulmonary heart disease patients is disorder in different degree,and this disorder aggravate as aggravating of state of disease.
