Hemodynamic digital twin · HFpEF + obesity + T2DM

A 52-week response,
simulated before week one.

CardioMetaIQ projects one patient's cardiometabolic trajectory under GLP-1 receptor agonists — a nine-state coupled ODE calibrated against published phase-3 evidence. Every projected number is sourced, hedged and auditable.

The instrument

CardioMetaIQ is a mechanistic digital twin of the obese HFpEF heart. A clinician enters one patient's phenotype; the twin integrates a coupled system of differential equations and returns a graded 52-week response prediction for GLP-1 receptor agonists — with the full trajectory, validation and uncertainty behind every number. Not a black box, and nothing is auto-prescribed.

How it works

From one phenotype to a graded trajectory.

Three deterministic steps. The same engine that reproduces trial-level endpoints in silico projects them forward for a single patient.

STEP 01
◉

Enter the phenotype

Baseline weight, LVEF, E/e′, NYHA class, NT-proBNP, diabetes status, GDMT and the candidate agent & dose — the entered identity that scopes every downstream claim.

9 baseline states · 1 patient
STEP 02
∿

Integrate the twin

A nine-state coupled ODE, forced by a GLP-1 drug fraction f(t), is integrated with RK4 at half-week steps across 52 weeks against the calibrated trial anchors.

STEP 03

Read the graded response

A 0–100 response score, placebo-corrected effect sizes (ETD), full state trajectories and a Monte-Carlo uncertainty band — each hedged and traceable to source.

in silico, then projected.

Before it predicts, the twin must recover what the trials already measured. Against the STEP-HFpEF echocardiography substudy it lands the left-atrial volume endpoint on target — and carries the placebo-corrected slope within published bounds.

The digital twin

Nine states,
one coupled system.

Weight loss is the driver — but it propagates. Falling adiposity unloads filling pressure, regresses LV mass and paracardial fat, lifts cardiac output and reserve, and steps down NYHA class. The twin makes those couplings explicit, so a prediction can be read as a mechanism, not a guess.
