Figure 3 Individual (left panel) and average (right panel) values of chest pain score during the first, second and third balloon inflations in control and bradykinin-treated patients. In control patients, the chest pain score decreased progressively from the first to the third inflation. In contrast, in bradykinin-treated patients the chest pain score did not change significantly during the three inflations. During all three inflations, the chest pain score was significantly less in bradykinin-treated compared with control patients. Values are means ± SEM.
