RESUMO
Objective To study the change of live circulation in advanced chronic cor pulmonale.Methods Determination of blood gas,liver function and rheohepatogram were performed in twenty-eight patients with chronic cor pulmonale in acute attack period before treatment,and accounted for the cardiac output(CO),hepatic blood flow(HBF),hepatic artery blood flow(HABF) and portal vein blood flow(PVBF).Results The experimental group was compared with the control group,the HBF,HABF and PVBF were decreased,which was more dramatic in the patients with chronic cor pulmonale,who had right ventricular failure complication in the acute attack period.Conclusion In acute attack period of chronic cor pulmonale,the liver circulation obstruction occurs early,and it is the main cause of liver damage for the patients.
