Post-operative high-sensitivity cardiac troponin I levels

	No ICA or no intervention (n = 4521)	Repeat revascularization (n = 86)	P-value
	Median (IQR)	Median (IQR)
Baseline hs-cTnI (ng/L)	9.0 (19)	14.5 (34)	0.06
hs-cTnI peak within 24 h (ng/L)	2407 (3231)	25 800 (30 390)	<0.001
hs-cTnI peak within 48 h (ng/L)	2407 (3231)	36 800 (43 006)	<0.001
Time to peak hs-cTnI within 24 h (h)	8.0 (7.0)	18.5 (5.7)	<0.001
Time to peak hs-cTnI within 48 h (h)	8.0 (7.6)	25.0 (13.4)	<0.001

Peak levels within 24 and 48 h post-surgery are represented. P-value represents two-sided non-parametric comparison, P-values were not adjusted for multiple comparisons, applying the Bonferroni correction for multiple tests did not change significant comparisons.

ICA, invasive coronary angiography; hs-cTnI, high-sensitivity cardiac troponin I; IQR, interquartile range.
