Cardiac Hepatopathy Severity Index (CHSI) Calculator

Cardiac Hepatopathy Severity Index (CHSI) — Explanation and Clinical Context This page implements a proposed, research-use-only Cardiac Hepatopathy Severity Index (CHSI): a transparent composite designed to summarize liver injury/functional impairment and chronic fibrosis surrogates commonly observed in congestive hepatopathy (cardiac hepatopathy). Because no single, widely-adopted numerical 'CHSI' exists in the lite

Cardiohepatic Index (Hepato-renal Risk Composite) Calculator

Cardiohepatic Index (Hepato-renal Risk Composite): Explanation and Clinical Context The Cardiohepatic Index (CHI) is a composite biomarker integrating hepatic and renal dysfunction to predict adverse outcomes in patients with advanced heart failure. It is calculated using serum bilirubin, creatinine, and sodium levels, reflecting the interplay between hepatic congestion, renal impairment, and systemic hemodynamics. E

Child-Turcotte-Pugh (CTP) Score Calculator

Child–Turcotte–Pugh (CTP / Child–Pugh) score — explanation and references The Child–Pugh score is a 5-item clinical scoring system originally developed to estimate prognosis in chronic liver disease and cirrhosis and to guide surgical risk assessment. Each of five parameters (total bilirubin, serum albumin, coagulation — expressed as INR or PT prolongation — ascites, and hepatic encephalopathy) is scored 1–3 points a

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)
