Why the study?
Does the cardiac hemodynamic status (CHS) index discriminate healthy versus pathological states?
Does the cardiac hemodynamic status (CHS) index discriminate healthy versus pathological states?
The newly introduced cardiac hemodynamic status (CHS) index provides an interpretable, Windkessel-consistent tool that effectively discriminates between healthy and pathological arterial states.

May support arterial screening; leaves open prospective validation before clinical adoption.
This study introduces the cardiac hemodynamic status (CHS), an interpretable index combining cardiac output, systemic vascular resistance, and arterial compliance into a single polar representation. CHS separates arterial stiffness orientation from overall hemodynamic load. The angle (CHS θ ) discriminates healthy versus pathological states (AUC = 0.866), whereas the magnitude reflects flow-resistance balance. This Windkessel-consistent index offers a practical tool for cardiovascular screening and longitudinal monitoring, with potential for bedside estimation from common biosignals.
