Summary Purpose Coronary computed tomography angiography ( CTA ) and several circulating biomarkers have prognostic value regarding cardiovascular disease ( CVD ) events, but their association is incompletely studied. We aimed to investigate whether markers of lipid metabolism, inflammation and kidney function could predict non‐obstructive coronary artery disease ( CAD ) determined by coronary CTA , in a low‐to‐intermediate‐risk group. Methods Coronary CTA and laboratory testing were performed for 115 subjects (45–70 years), with low prevalence of CVD risk factors, predominantly low‐to‐intermediate Framingham risk and normal or mildly reduced kidney function. Results Forty‐nine (43%) had no CAD at coronary CTA , and 66 (57%) had CAD in ≥1 segment (stenosis < 50%). Adiponectin was inversely associated with CAD , and lipoprotein(a) and cystatin C were associated with CAD at coronary CTA . In multivariable logistic regression, cystatin C remained an independent predictor of CAD ( OR : 2·50, 95% CI : 1·12–5·59). Cystatin C also correlated to the number of diseased segments ( r s = 0·25, P <0·01). Conclusion Higher plasma levels of cystatin C were associated with non‐obstructive CAD at coronary CTA in subjects with low‐to‐intermediate CVD risk and normal to mildly reduced kidney function.
