algorithm to stratify clinical decompensation risk in patients with compensated advanced chronic liver disease (chess2108)

Conditions: Compensated Advanced Chronic Liver Disease

Summary: compensated advanced chronic liver disease (cacld) commonly indicates severe fibrosis and compensated cirrhosis at risk of developing clinically significant portal hypertension (csph) and hepatic decompensation. the presence of csph (defined as hepatic venous pressure gradient \[hvpg\] ≥ 10 mmhg) is the strongest predictor of hepatic decompensation. however, hvpg measurement is invasive, operator dependent, and not widely available. according to the 2021 updated easl clinical practice guidelines, cacld patients who did not meet the baveno vi criteria but had any of the two variables (lsm \> 20 kpa or plt \< 150 × 109/l) were suggested to perform screening endoscopy and hvpg measurement. however, the number of cacld patients with unfavorable baveno vi status is huge, no detailed risk stratifications existed at this timepoint. this study intended to investigate a novel algorithm to stratify the decompensation risk in patients with cacld.
