Caristo Diagnostics
About Caristo Diagnostics
Caristo Diagnostics is a global leader in AI-powered cardiac and vascular disease diagnostics and risk prediction, spun out from the University of Oxford. The company’s flagship technology, CaRi-Heart®, utilizes advanced AI algorithms to analyze routine cardiac CT angiography (CCTA) scans. This innovative approach allows for the visualization and quantification of perivascular fat inflammation, a previously invisible yet critical biomarker for coronary artery disease (CAD) and a strong predictor of future cardiac events, often years before symptoms manifest.
For physicians, CaRi-Heart provides a comprehensive report that includes the patient-specific Fat Attenuation Index (FAI), a patented biomarker for coronary inflammation, and an individualized CaRi-Heart Risk score, which assesses the absolute 8-year risk of a fatal heart attack by integrating inflammation status with standard clinical risk factors and plaque presence. The technology aims to transform cardiac care from a reactive model to a proactive one, enabling earlier detection, personalized prevention strategies, and refined treatment decisions. Caristo also offers CaRi-Plaque™ technology for quantitative characterization of coronary plaque and stenosis. The CaRi-Heart technology is CE Mark certified for use in the UK, EU, and Australia, and the company is actively pursuing FDA clearance and CPT codes for broader adoption in the U.S.

What Physicians Need to Know
For physicians, Caristo Diagnostics offers a paradigm shift in cardiovascular care by enabling earlier and more precise risk stratification. The CaRi-Heartu00ae and CaRi-Plaqueu2122 analyses provide critical insights into coronary inflammation and plaque characteristics that are not visible with standard CCTA interpretation alone. This allows for proactive intervention, personalized treatment strategies (including lifestyle modifications and targeted medications), and improved patient outcomes, particularly for those with non-obstructive CAD who are often misclassified as low risk. The rapid turnaround of reports (typically within 48 hours) facilitates timely clinical decision-making.
Caristo's CaRi-Heartu00ae platform is a cloud-based Software as a Service (SaaS) medical device designed for seamless integration into existing clinical workflows. It accepts de-identified CCTA scans from most scanner models or PACS systems via secure and anonymized data transfer. The analysis results are delivered to healthcare professionals as intuitive, actionable reports in either DICOM-conformant files or PDF format. For users of CaRi-Plaqueu2122, there is a seamless adoption pathway for CaRi-Heartu00ae once it receives full FDA clearance in the US.
What the Web Says
Caristo Diagnostics is an Oxford, UK-based company specializing in AI-powered cardiovascular imaging and diagnostics. Their flagship product, CaRi-Heart, utilizes advanced AI algorithms on routine cardiac CT scans to visualize and quantify coronary inflammation, a key indicator of heart attack risk. The company has received positive attention for its innovative approach to preventative cardiac care, with studies suggesting its technology could significantly reduce cardiac deaths and costs.
Overall: PositiveStrengths
- AI-powered technology for early heart attack prediction (up to 10 years in advance)
- Identifies coronary inflammation, a previously invisible root cause of heart disease
- Cloud-based software, agnostic to the type of scanner
- Clinically validated and supported by studies published in leading medical journals
- Potential to reduce cardiac deaths and healthcare costs
- FDA 510(k) clearance for CaRi-Plaque for coronary plaque detection
Limitations
- CaRi-Heart is currently for investigational use only in the United States, though CaRi-Plaque has FDA clearance
- Limited information on employer reviews from major platforms like Glassdoor or Indeed
- Some Reddit discussions express concerns about the cost and potential for insurance companies to use such technology to deny claims or increase premiums
- Early evidence about clinical utility of CaRi-Heart Risk is underdeveloped and has limitations in terms of risk of bias and applicability to UK clinical practice
- Lack of information on how treatment could change as a result of using CaRi-Heart and whether any changes would improve outcomes for patients
