Table 5.

Associations between baseline concentrations of A) sTnI and B) hsTnI and presence or extent of epicardial CAD and coronary artery calcium score in patients undergoing CTA. Extremely low concentrations of TnI using both methods (but particularly hsTnI) were associated with less epicardial CAD and absence of coronary artery calcium.

A) sTnI

	sTnI <LOD	sTnI LOD to 99^th percentile	sTnI ≥99^th percentile
Calcium score, median (IQR)	0 [0–28]	0.1 [0–3]	213 [38–521]
Any CAD	55.6%	50.0%	90.0%
Stenosis >50%	18.8%	16.7%	80.0%
Stenosis >70%	12.5%	0%	70.0%

B) hsTnI

	hsTnI <LOD	hsTnI LOD to 99^th percentile	hsTnI ≥99^th percentile
Calcium score, median (IQR)	0 [0-0]	0 [0–29]	111 [0.2–480]
Any CAD	11.1%	58.3%	83.3%
Stenosis >50%	0%	19.4%	75.0%
Stenosis >70%	0%	13.0%	58.3%

LOD denotes: limit of detection; IQR denotes: interquartile range; CAD denotes: coronary artery disease
