Safety and incremental prognostic value of stress cardiovascular magnetic resonance in patients with known chronic kidney disease

Table 6 Discrimination and reclassification associated with in inducible ischemia and unrecognized MI for the prediction of MACE

	MACE
	C-index (95%CI)	NRI (95%CI)	IDI (95%CI)
Model 1 (traditional CV risk factors) *	0.74 (0.69–0.78)	Reference	Reference
Model 2 (model 1 + unrecognized MI) ^†	0.82 (0.76–0.87)	0.250 (0.067–0.440)	0.035 (0.018–0.060)
Model 3 (model 2 + inducible ischemia) ^‡	0.87 (0.83–0.90)	0.477 (0.236–0.678)	0.049 (0.025–0.071)

*Model 1 included traditional CV risk factors: age, male, BMI, diabetes mellitus, hypertension, dyslipidemia, current or previous smoking, family history of CAD, LVEF, GFR, and time between CKD diagnosis and CMR exam
^†Model 2 included: model 1 with unrecognized MI
^‡Model 3 included: model 2 with inducible ischemia
Same as in Table 2. IDI integrative discrimination index; NRI net reclassification improvement
