A Biograph study applying Caristo's CaRi-Heart AI to routine coronary CT angiography found elevated perivascular inflammation in 42.9% of asymptomatic adults classified as low risk, with 17.9% showing very high inflammation in at least one major coronary artery. Roughly 47% had no detectable plaque yet still showed inflammatory signal, and no lipid marker, HbA1c, hs-CRP or the AHA PREVENT-ASCVD score correlated with the finding. The study size was not disclosed and the results were announced by the clinic that provides the testing.
Key Points
- 42.9% of low-risk asymptomatic adults showed elevated coronary inflammation
- ApoB, hs-CRP, HbA1c and risk calculators identified none of them
- Nearly half with inflammation had no detectable arterial plaque
Longevity Analysis
Vascular inflammation appears to precede the structural changes that current screening is built to detect, which means a standard lipid panel and a risk score can return reassuring numbers while the arterial wall is already under immune activation. Imaging that reads the tissue surrounding the vessel rather than the lumen shifts cardiovascular assessment from documenting accumulated damage to interpreting an active process — a meaningful distinction when the intervention window spans decades. Whether acting on perivascular inflammation changes outcomes remains unestablished, and the finding is best treated as a signal requiring clinical context rather than a diagnosis.
