of heart attack, stroke, and diabetes. Caristo was highlighted by Nature in 2020 as one of the most exciting science-based companies to have emerged from academic labs. To-date Caristo has attracted over £23 million in venture capital investment (nearly US$30 million).

Named first of “7 Technologies That Could Change Heart Healthcare Forevermore” by the Robb Report, the CaRi-Heart technology is Caristo’s flagship offering which aids coronary artery disease diagnosis with improved risk prediction. It applies advanced AI algorithms to routine cardiac CT scans to visualize and quantify coronary inflammation, which is the previously invisible root cause of the disease. Each patient’s CaRi-Heart Report includes several clinical results: (1) the patient specific Fat Attenuation Index (FAI), a novel and patented biomarker for the measurement of coronary inflammation, which indicates the patient’s risk in % relative to a matched peer group; (2) CaRi-Heart Risk, which assesses the absolute 8-year risk of a fatal heart attack (based on both coronary inflammation status and standard clinical risks factors); and (3) coronary plaque-specific characterization and quantification. The CaRi-Heart Analysis is supported by the CaRi-Heart software, which is cloud-based and agnostic to the type of scanner generating the routine cardiac CT images. The CaRi-Heart technology is CE Mark certified under the latest EU MDR with UKCA marking being received in September 2022. CaRi-Heart is limited to research use in the U.S. before the FDA grants marketing authorization.

Multiple patents underpinning CaRi-Heart technologies have been granted in major jurisdictions around the world. In addition, exceptional validation results showing Cari-Heart’s ability to aid the prediction of heart attacks have been published in leading medical journals including the Lancet, JACC, European Heart Journal, and Cardiovascular Research. CaRi-Heart validation and implementation projects have been supported by multiple UK government grants and awards, including the NHS AI Stage 3 Award for real-world evaluation and implementation of CaRi-Heart care pathway in multiple NHS hospitals. With its deep clinical insights, proven validity and implementation readiness, the CaRi-Heart Analysis Service and the resulting new care pathway can transform cardiac care around the world by aiding in better prediction and prevention of future heart attacks.
