Hemodynamic Effect of Simvastatin With Beta Blockers in Clinical Portal Hypertension

Summary

In the genesis and maintenance of PH associated with liver cirrhosis are two mechanisms that act synergistically. The first is an increase in hepatic vascular resistance, due in part to the disruption of liver structure inherent cirrhosis, and increased hepatic vascular tone is caused by the contraction of perivascular smooth muscle cells, myofibroblasts and hepatic stellate cells, which represents about 30% of global intrahepatic resistance and is believed to be due to the production Defective nitric oxide (NO). The second mechanism, which maintains and exacerbates HTP, is an increase of splanchnic blood flow caused by increased NO and other vasodilators at this level In this regard, we believe that in patients with compensated liver cirrhosis, with portal pressure gradient\> 10 mmHg, both acute responders betablockers test as non-responders, the association of antifibrotic drugs and / or vasodilators, chronic liver selective May be beneficial in the control of portal hypertension
