A clearer cardiovascular aging signal
Published · European Heart Journal 2026

Know what your heart may be trying to tell you.

Understand patterns routine screening may not reveal, while there is still time to ask better questions and take control.

CardioSight brings your existing imaging, labs, and health context into one intuitive Heart Age designed to start a more useful conversation with your care team.

The unseen problem

You may already have the scan. The information inside it may never have been translated.

A chest CT is usually read for the single reason it was ordered. The texture and distribution of fat directly surrounding the thoracic aorta may contain additional information about cardiovascular aging that is not part of a routine read.

That information doesn't disappear. It sits in your imaging, unread and unexplained. CardioSight is built to translate it into something you can understand — a single Heart Age.

How it works

From scattered health data to a Heart Age you can use.

The solution localizes cardiovascular signals in information you already have, places them in context, and turns the result into a report built for a patient-clinician conversation.

    Existing chest CT

    Start from a chest CT or coronary calcium scan you already have. No new imaging, no radiation.

  2. 02

    Heart & aorta segmentation

    The pipeline identifies the heart and thoracic aorta as anatomical landmarks for the analysis.

  3. 03

    Fat depot mapping

    Peri-aortic fat is the current research signal; epicardial, pericardial, intermuscular, and subcutaneous depots expand the map.

  4. 04

    Radiomic feature extraction

    Volume, attenuation, and texture features are extracted from the peri-aortic fat.

  5. 05

    Heart Age

    The localized imaging phenotype is translated into one intuitive number and placed in reference-population context.

Imaging insight

The localized peri-aortic tissue signal resembles an older-appearing cardiovascular phenotype in the research model.

This is not a diagnosis or a prediction of a specific event. It is an imaging-derived reason to place the scan in the context of the person's broader cardiovascular health.

What you receive

One clear number, explained.

Your report centers on a single Heart Age, the localized CT signal behind it, and a plain-language explanation of what it can and cannot mean.

  • Heart Age. One imaging-derived estimate of how old the cardiovascular tissue phenotype appears.
  • What was analyzed. The volume, attenuation, and texture of fat directly surrounding the thoracic aorta.
  • Plain-language explanation. What the result means, what it doesn't, and what to do next.
  • A prompt to talk to a clinician. Designed to support — not replace — clinical evaluation.

Localized insight

A peri-aortic tissue signal was isolated and translated through the validated age model.

Next: review the result alongside standard cardiovascular risk factors with a clinician.

Illustrative example. Heart Age is an estimate of how old the cardiovascular system appears based on imaging features — not a diagnosis or a prediction of a specific event.

The science

Start with the strongest signal. Expand the map responsibly.

Peri-aortic adipose tissue is the foundation of the current published model. CardioSight measures its volume, attenuation, and texture while developing a broader view across epicardial, pericardial, intermuscular, and subcutaneous fat depots.

Anatomical localization

Heart and aorta segmentation establishes the anatomical landmarks needed to isolate the fat directly surrounding the thoracic aorta.

A mapped adipose phenotype

A 31-feature peri-aortic signature anchors the current Heart Age model. Additional fat depots are an explicitly labeled expansion, not presented as validated today.

Not a diagnosis

Heart Age is educational, imaging-derived information. It is designed to support, not replace, clinical evaluation.

Published multicenter validation

The model was trained in 4,451 scans and externally validated in 44,214 scans across four CT cohorts.

Peri-aortic fat to assess cardiovascular aging using an AI-driven radiomic biomarker

Lebowitz M, Modanwal G, Singh A, et al. European Heart Journal, 2026. A peri-aortic adipose radiomic signature was trained in 4,451 scans and externally validated in 44,214 scans across four CT cohorts, estimating cardiovascular age with a mean absolute error of 2.7 years in the primary external validation.

    Open your Heart Age in the portal, save a PDF, and bring it to a clinician conversation.

Early access uses direct upload or an authorized records request. Direct portal and automated imaging-network retrieval are planned integrations and will only be described as live when they are available.

For health systems

Keep quiet risk from slipping through the cracks.

Give radiology and cardiology teams a way to surface an aging signal from CT studies already moving through care, then route appropriate patients into a follow-up pathway.

  • Confidence beyond the routine read

    Help the care team see a cardiovascular-aging pattern that may not be visible in standard risk fields.

  • Fewer missed follow-up opportunities

    Create a consistent route from an imaging signal to an appropriate clinician review queue.

  • A workflow clinicians can use

    Return Heart Age inside the PACS and health-system workflow rather than in another disconnected portal.

  • A measurable service line

    Track eligible studies, completed analyses, patient outreach, and downstream follow-up without promising a diagnosis.

Why we're building CardioSight

Information that already exists should reach the person it's about.

Millions of people carry a chest CT in their records that contains signal about how their cardiovascular system is aging — signal that is rarely extracted, explained, or connected to prevention. We started CardioSight to close that gap.

CardioSight is led by Mendy Lebowitz, first author of the peri-aortic Cardiovascular Age study published in the European Heart Journal (2026), working with a team of imaging-AI researchers and clinicians.

FAQ

Common questions, straight answers.

I already had a chest CT — is there cardiovascular information in it I never heard about?
It may. A chest CT is usually read for the reason it was ordered. CardioSight analyzes radiomic patterns in the fat directly surrounding the thoracic aorta that are not part of a routine read.
Can my cardiovascular system look older or younger than my actual age?
Yes. Heart Age is an imaging-derived estimate of how old your cardiovascular system appears relative to a research reference population.
Do I need another scan or more radiation?
No. CardioSight uses a chest CT or coronary calcium scan you already have — no new imaging and no additional radiation.
What does the AI analyze?
It uses the heart and aorta as anatomical landmarks, segments the fat directly surrounding the thoracic aorta, and extracts volume, attenuation, and texture features that are translated into one Heart Age.
Is Heart Age a diagnosis or a prediction that I'll have a heart attack?
No. It is educational, imaging-derived information — not a diagnosis, not a risk percentage, and not a prediction of a specific event. It's designed to support a conversation with a clinician.
What if my Heart Age looks accelerated?
It's a prompt to look closer, not a verdict. Discuss the result with a qualified healthcare professional who can put it in the context of your full health picture.
Will a clinician review my result?
An optional clinician consultation is being developed. It is not part of the standard result today, and we don't advertise mandatory clinician review.
How do you get my scan, and how do I receive the report?
You upload a scan you have, or we help you request it from your imaging center. Your result is delivered by email and a secure portal. Automated health-record connections are planned, not yet live.
Who can access my imaging and health information?
Only the people and systems needed to produce your result. We don't sell your data, we use granular revocable consent, and you can delete submitted scan and report data from your account.
Is CardioSight FDA-cleared?
No. CardioSight is not FDA-cleared or approved. It provides educational, imaging-derived information and is not a substitute for professional medical evaluation.
