A U.S. study applying AI-enabled coronary CT angiography analysis to asymptomatic, conventionally low-risk adults found elevated perivascular inflammation around the coronary arteries in 42.9% of participants, with 17.9% classified as very high. Nearly half of those with no detectable plaque still showed inflammatory signal, and standard markers including ApoB, non-HDL-C, HbA1c, hs-CRP and the PREVENT-ASCVD calculator did not correlate with these findings. Prognostic value and clinical benefit remain to be validated.
Key Points
- 43% of low-risk asymptomatic adults showed elevated coronary perivascular inflammation
- 47% without detectable plaque still had inflammatory vascular signal
- Standard lipid, glycemic and hs-CRP markers failed to identify affected individuals
Longevity Analysis
Vascular inflammation appears to operate as an upstream process, active well before plaque is measurable and invisible to the blood-based panels most risk stratification depends on. The discordance between circulating markers and local arterial immune activity illustrates how a signal generated in one tissue compartment can be missed entirely when measured elsewhere, and argues for imaging that reads the vessel wall directly rather than inferring its state. Whether identifying this phase changes outcomes depends on what follows detection — sustained reduction of inflammatory drivers and disciplined longitudinal tracking, not the scan itself.
