Evidence base

Built on the literature,
not in spite of it.

CardioMetaIQ is anchored to the phase-3 trials that defined GLP-1 therapy in obesity-related HFpEF. Every calibration target, generalization and validation check traces to a published source.

Primary anchors

The trials behind the twin.

SUMMIT

Tirzepatide in obesity-related HFpEF

Packer M et al. NEJM 2024 · JACC 2025

The primary calibration anchor for weight-driven hemodynamics and the headline e_W parameter. SUMMIT also supplies the per-patient cohort scatter reproduced in Figure 2.

STEP-HFpEF

Semaglutide 2.4 mg in HFpEF + obesity

Kosiborod MN et al. NEJM 2023

Calibrates the symptom and functional-class trajectory under semaglutide in the non-diabetic obese HFpEF population, and rescales e_W across the GLP-1 class.

NYHA / KCCQ6-min walkE/e′
STEP-HFpEF-DM

Semaglutide in HFpEF + obesity + T2DM

Kosiborod MN et al. NEJM 2024

Extends calibration to the type-2-diabetes phenotype, supporting the diabetes-status generalization the twin applies when the phenotype carries T2DM.

ECHO SUBSTUDY

STEP-HFpEF echocardiography substudy

Solomon SD et al. JACC 2024

The held-out external validation target (Figure 5): left-atrial volume, E/e′, RV areas and LV mass. The twin reproduces the LA volume endpoint on target without a dedicated state.
