Exploration on the Effect of Nonselective -Receptor Blockers (NSBBs) on Hemodynamic Parameters in Complicated Liver Cirrhosis.

Esophageal-gastric variceal bleeding occurs in 5-15% of patients with liver cirrhosis annually, and the mortality rate is as high as 20% within 6 weeks of the first bleed. The more compromised the liver function, the higher the mortality. Effective control of bleeding is pivotal for reducing mortality in patients with liver cirrhosis.
