  1. 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.
