Relationships between hemodynamic alterations and Child-Pugh Score in patients with cirrhosis

Hepatogastroenterology. Sep-Oct 2005;52(65):1521-5.

Abstract

Background/aims: In this study, central and nonsplanchnic hemodynamic alterations in liver cirrhosis and correlation between Child-Pugh Score and these hemodynamic alterations were evaluated.

Methodology: With this aim, angiotensin-I, aldosterone, femoral blood flow, cardiac index, free water clearance and renal blood flow index were evaluated in 30 cirrhotic patients and 10 healthy control subjects.

Results: Child-Pugh score was found to be directly related with serum levels of angiotensin-I and aldosterone, cardiac and renal blood flow index (r = 0.60 - p < 0.001, r = 0.57 - p < 0.01, r = 0.55 - p < 0.01 and r = 0.65 - p < 0.001 respectively), and indirectly related with free water clearance and femoral blood flow (r = 0 .72 -p < 0 .001, r = 0.71 -p < 0 .001 respectively).

Conclusions: We concluded that, in patients with cirrhosis, as the Child-Pugh score becomes greater angiotensin-I and aldosterone, cardiac output and non-splanchnic vasoconstriction progressively increase, on the other hand free water clearance and renal perfusion progressively decrease. Alterations in cardiac index and femoral artery blood flow begin before ascites formation. And the hyperdynamic circulation is a primary event independent of the central blood volume.
