Key result
Total arterial compliance index measured by impedance cardiography strongly predicted all-cause mortality in the general population (standardized HR 0.38; 95% CI 0.31-0.46; P<0.0001).

ICG hemodynamics may identify mortality risk beyond BP; leaves open incremental value over standard models in general populations.

Do hemodynamic patterns identified by impedance cardiography predict all-cause mortality in the general population?
Hazard Ratio: 0.38 (95% CI 0.31–0.46)
p-value: p=<0.0001
Hemodynamic parameters measured by impedance cardiography, such as arterial compliance and cardiac contractility indices, independently predict long-term all-cause mortality in the general population, even in those without severe hypertension.
Medina‐Lezama et al. (2018) conducted a cohort in General population (n=1,639). Hemodynamic parameters measured by impedance cardiography (ICG) was evaluated on all-cause mortality (standardized HR 0.38, 95% CI 0.31-0.46, p=<0.0001). Total arterial compliance index measured by impedance cardiography strongly predicted all-cause mortality in the general population (standardized HR 0.38; 95% CI 0.31-0.46; P<0.0001).
