Figure 3 Effect of abciximab on epicardial (left) and microvascular (right) coronary resistance. Data are shown as average values ± SEM before treatment (open circles connected by solid line), after abciximab (open squares connected by dashed line), and after stenting (solid triangles connected by dotted line). Abciximab limited the increase of epicardial resistance induced by hyperventilation and significantly reduced microvascular resistance in the jeopardized coronary vascular bed under all study conditions. *p < 0.05 vs. corresponding baseline. °p < 0.01 vs. corresponding condition without abciximab. p < 0.01 vs. corresponding condition after abciximab.
