Figure 2

Angiogenesis index in relation to step of dyspnea: 0 - without dyspnea (n = 50), 1 - mild dyspnea after big effort (n = 30), 2 moderate dyspnea (n = 81), 3 - severe dyspnea (n = 55), 4 - very severe at rest (n = 9). The mean values are indicated by horizontal bars, significant differences between the groups are as follows: *P < 0.05, **P < 0.01, and ***P < 0.001).
