Physiologic response to stress.
| Measure | Overall (N = 161) | MS-provoked ischemia | ||||
|---|---|---|---|---|---|---|
| Yes (N = 64) | No (N = 97) | |||||
| BL | MS | BL | MS | BL | MS | |
| SBP | *133.6 ± 18.4 | 159.5 ± 21.0 | *136.1 ± 21.0 | 160.1 ± 23.6 | *130.6 ± 16.4 | 159.1 ± 19.6 |
| DBP | *75.2 ± 10.1 | 88.4 ± 10.8 | *76.8 ± 10.7 | 87.5 ± 11.3 | *74.3 ± 9.7 | 88.9 ± 10.5 |
| HR | *59.1 ± 11.0 | 68.6 ± 11.9 | *61.3 ± 13.3 | 70.6 ± 13.6 | *57.8 ± 9.3 | 67.4 ± 10.7 |

| Norepinephrine (pg/mL) | 365.5 ± 259.2 | 389.9 ± 236.7 | 402.6 ± 263.2 | 437.4 ± 275.0 | 341.0 ± 254.9 | 358.2 ± 202.7 |
Values are mean ± standard deviation. Changes from BL to MS in both SBP and DBP and HR were all significant at the *p < 0.0001 level, however, the differences in BL or MS values between those with (YES) versus without (NO) MS-provoked ischemia were not statistically significant. There were no significant differences in epinephrine and norepinephrine across conditions or between groups.
