Figure 2 Incidence of clinical restenosis by tertiles of CRP, SAA and fibrinogen in patients with stable (open bars) and unstable angina (solid bars). In stable angina patients, the incidence of restenosis increased from 33% in the I tertile to 86% in the III tertile of CRP and fibrinogen (Mantel-Haenszel test for linear association: p = 0.046) and from 32% in the I tertile to 67% in the III tertile of SAA (p = 0.13). Among the unstable angina patients the incidence of restenosis increased from 25% in the I tertile to 72% in the III tertile of CRP (Mantel-Haenszel test for linear association: p = 0.004) and from 23% in the I tertile to 67% in the III tertile of SAA (Mantel-Haenszel test for linear association: p = 0.010). In patients with unstable angina, fibrinogen levels were not associated with the incidence of restenosis (p = 0.65). The incidence of restenosis was similar in stable and unstable angina patients in the III tertile of CRP or SAA. CRP = C-reactive protein; SAA = serum amyloid A protein.
