NCH Becomes First U.S. Hospital to Use AI That Detects Hidden Heart Attack Risk a Decade in Advance
Caristo's FDA-cleared technology analyzes coronary CT angiography (CCTA) scans, the first-line test for patients with chest pain, to identify high-risk plaque that may lead to future heart attacks. is the only technology in the world able to detect and quantify coronary inflammation, an early driver of heart disease, without waiting for patients to develop visible plaque.
Current clinical pathways often fail to identify high risk patients by missing inflammatory disease activity and relying on plaque assessment alone. In fact, twice as many fatal and non-fatal cardiac events occur in patients without obstructive plaque on CCTA. A major breakthrough, technology provides a risk score to help doctors and patients understand the likelihood of a cardiac event up to 10 years in advance, even in the absence of visible plaque [ Lancet , 2024]. The technology is widely used in Europe and currently under FDA review.
"This NCH-Caristo collaboration represents a new paradigm in cardiovascular medicine," said , Section Head of Cardiac Imaging at NCH Rooney Heart Institute. "Doctors are used to responding to cardiac events after they happen. Caristo has the first clinically validated AI solutions that let us prevent heart attacks a decade before they occur."
NCH is recognized by as one of America's Top 50 Hospitals and among the top three in Florida for cardiac care. Under the new collaboration every NCH Rooney Heart Institute patient who qualifies for plaque analysis will have their CCTA scan analyzed by CaRi-Plaque™. NCH will also deploy CaRi-Heart™ as part of a research program, giving physicians the ability to incorporate the inflammation-based risk score into treatment and outcomes research.
In addition, NCH is launching a new preventive heart health service for people who elect to proactively manage their health before any cardiac symptoms. This self-pay program allows anyone concerned about their heart health to be enrolled into the NCH-Caristo program.
"Patients will have the best opportunity to avert a heart attack here at NCH," said , Director of Preventive Cardiology, NCH Rooney Heart Institute. "This technology is built on world-class science and rigorous clinical research. It allows us to identify and address heart disease before it causes harm."
The collaboration coincides with Caristo Diagnostics' upcoming symposium at the American Heart Association (AHA) Scientific Sessions 2025, where experts including Drs. Orringer and Wang will discuss how imaging and AI are changing the way clinicians detect and manage coronary disease.
