Portal hypertension causes two main clinical problems for the patient: hyperdynamic circulation and development of esophageal or gastric varices.Liver cell destruction causes shunting of blood and increased cardiac output.Vasodilation is also present (so vasodilators are not needed),which causes decreased perfusion to all body organs,even though the cardiac output is very high.This phenomenon is known as high-output failure or hyperdynamic circulation.Clinical signs and symptoms are those of heart failure and include jugular vein distention,pulmonary crackles,and decreased perfusion to all organs.Blood pressure decreases and dysrhythmias are common.Guaiac-positive stools may be an indication of gastrointestinal bleeding.
