In order to derive a reliable correlation between statin use and the reduction of portal hypertension, it is necessary to proceed with a clinical study with a high level of evidence, such as a randomized controlled clinical trial study. In addition, previous small randomized controlled trials had a limitation in that patients with various causes of liver cirrhosis were included. In this study, only patients diagnosed with chronic hepatitis B and compensated cirrhosis who are taking antiviral treatment will be included in the study, and in patients whose viral activity are suppressed by taking antiviral treatment, it was investigated whether statin administration had a significant effect in additionally improving portal pressure. We want to prove it through a randomized controlled clinical trial study.
