Table 3.

Absolute and relative changes in plasma cTnT levels in peripheral blood (as measured by the hs-cTnT assay) from baseline to 180-minutes following pacing-induced stress among the entire cohort and when stratified by presence of CAD and lactate release.

	Entire cohort	CAD− / lactate −	CAD+ / lactate −	p- value	CAD+ / lactate +	p- value
Absolute ΔcTnT [median (25^th,75^th)], pg/mL	6.8 (3.4,9.1)	6.8 (6.2,8.7)	5.4 (3.3,9.1)	0.50	8.8 (3.4,20.8)	0.94
Relative fold ΔcTnT [median (25^th,75^th)]	2.3× (1.4×,4.2×)	5.2× (2.3×,6.8×)	2.0× (1.4×,3.3×)		1.7× (1.1×,3.8×)
≥2-fold increase [# of patients (%)]	11/19 (58)	4/5 (80)	4/7 (57)		3/7 (43)
≥3-fold increase [# of patients (%)]	7/19 (37)	3/5 (60)	2/7 (29)		2/7 (29)
