Intelligence in harmony.

Decision intelligence for cardiovascular medicine

Harteis builds decision intelligence engines for cardiovascular medicine, developed inside a rigorous simulation environment before they ever meet a patient. Its engines learn, adapt and explain themselves, and the clinician always holds final authority.

(01) Premise

Cardiovascular decisions are high-stakes, time-critical and data-saturated. Clinicians don't need another black box; they need engines that show their reasoning, fit their workflow, and know their limits. Building those engines is what Harteis does: rigorously, before anything reaches practice.

(02) How it holds
P·01

Clinical grounding

Models train on curated cardiovascular caseloads and are validated against clinical practice, not just benchmarks.

→
P·02

Explainability

Every recommendation carries its reasoning and its uncertainty. Understanding is part of the output, not an appendix.

→
P·03

Calibrated trust

Confidence is measured, audited and continuously re-calibrated. The engine knows what it doesn't know, and says so.

→
P·04

Clinician authority

The engine deliberates; the clinician decides. Final call stays with people, by architecture, not by promise.

(03) The sandbox

Where clinical intelligence earns the right to practice.

Harteis builds cardiovascular decision models and grows them inside simulation: synthetic caseloads with real-world texture, adversarial cases surfaced deliberately, reasoning inspected in the open. Models face our evaluation harness across thousands of scenarios before any real-world exposure, and every step is auditable.

Simulation wards

Synthetic cardiovascular caseloads with real-world texture: flow, pressure, noise, ambiguity, rehearsed thousands of times before a single real encounter.

Adversarial curricula

Rare presentations and edge cases surfaced in training deliberately, so models fail safely in simulation rather than unexpectedly in practice.

Explanation studio

Where reasoning is opened, inspected and challenged by clinicians, until the why is as reliable as the what.

Evaluation harness

Continuous measurement of calibration, safety and clinical agreement. Not a gate at the end, a pulse throughout.

What we build Cardiovascular prediction models, with the infrastructure to run them safely
01

Prediction models

Cardiovascular risk and trajectory models trained on curated clinical datasets, engineered for calibration and clinical agreement.

02

Built-in AI monitoring

Every deployed model is watched by a built-in monitoring layer that tracks drift, performance and safety across sites in real time, without moving patient data.

03

PII stripper

Automatic de-identification on ingestion: identifiers are removed before data ever reaches a model, by design.

04

EHR integration

Deploys inside existing hospital workflows, surfacing predictions and their reasoning where clinicians already work.

Backed by peer-reviewed research, and accountable to it.

(04) Trust, structural

Trust is earned in simulation, then verified in the clinic. Safety, transparency and clinical accountability are built into the architecture, not appended after.
