the impaired responses of the cardiac transplant patients were not the result of a nonspecific depression of cardiovascular reflexes , since increases in mean arterial pressure ( 12 +/- 3 vs 10 +/- 2 mm hg ) , forearm vascular resistance ( 19.5 +/- 3.4 vs 18 +/- 5.8 units ) , and plasma norepinephrine ( 56 +/- 8 vs 42 +/- 11 pg/ml ) during cold pressor test were not significantly different in the two groups .
