Congestive Hepatopathy (Congestive Hepatic Fibrosis Score, CHFS) Calculator

Congestive Hepatic Fibrosis Score (CHFS): explanation and clinical context The CHFS is a histology-based grading system that stages fibrosis patterns seen in congestive hepatopathy on liver biopsy — it ranges from 0 (no fibrosis) through 4 (cirrhosis), with intermediate grades that distinguish centrizonal-limited fibrosis (stage 1), combined centrizonal and portal patterns with differing zone predominance (2A and 2B), and bridging fibrosis (3); CHFS correlates with measures of right-sided cardiac pressure/volume overload and provides a standardized, pathology-centered way to communicate severity of congestion-related liver remodeling, but it must always be interpreted in the clinical context because sampling heterogeneity is common and noninvasive tests (elastography, blood-based fibrosis markers) and hemodynamics add important complementary information.
