Correlation of aspartate aminotransferase/platelet ratio index with hepatic venous pressure gradient in cirrhosis

摘要

BackgroundHepatic venous pressure gradient (HVPG) is a prognostic marker in cirrhosis, but is invasive. There is a need to validate a noninvasive marker to measure portal hypertension. Aspartate aminotransferase/platelet ratio index (APRI) is proposed as a good noninvasive estimator of hepatic fibrosis. Whether APRI could be used as noninvasive tool to measure portal hypertension has not been studied.
