Abstract
to study relationship between parameters of intracardiac hemodynamics assessed by Doppler echocardiography and functional activity of endothelium, hepatic blood flow and severity of portal hypertension in patients with cirrhosis of the liver (CL) of different etiology. We found that changes of structural and functional parameters of the heart in LC depended on the stage of compensation of portal hypertension and were accompanied by rearrangement of parameters of intracardiac hemodynamics. Pulmonary arterial hypertension (PAH) was found in 11.1% of patients with LC. PAH was moderate and was more frequent in patients with end-stage disease (Child-Pugh class C) compared with those with initial stage of LC (21.4% and 6.3%, p<0.05, respectively). Disorders of vasoregulating endothelial function in patients with CL were related to parameters of cardiopulmonary hemodynamics and functional state of the right ventricle and were more pronounced in patients with PAH.
