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. Elevated CHI values indicate higher risk of mortality and morbidity, guiding clinicians in risk stratification, monitoring, and management of cardiohepatic-renal interactions.
