Difference in VEGF and NRG-1β by Stress-Induced Ischemia

Median (range) ± SD	Positive Ischemia n = 23	Negative Ischemia n = 37	p value
serum VEGF (pg/ml)	247 (16 –1148) ± 312	163 (16 –1538) ± 384	0.40^*
plasma VEGF (pg/ml)	131 (16 –1399) ± 298	103 (20 –744) ± 150	0.84^*
serum NRG (ng/ml)	2.4 (0.2 –19.1) ± 4.3	1.6 (0.2 –17.9) ± 3.8	0.13^*
plasma NRG (ng/ml)	4.1 (1.9 –12.9) ± 2.2	3.3 (1.4 –10.5) ± 1.9	0.02^*
