Figure 2. Leg and forearm vasodilator response to intra‐arterial acetylcholine and epoprostenol before and after ischemic preconditioning of the forearm.

Absolute changes from baseline in leg and forearm vascular conductance with arterial infusion of acetylcholine (A and B) and epoprostenol (C and D). Data are presented as mean±SEM (n=12). *Significantly different from pre.
