Figure 1 Relationship between peak creatine kinase (CK) value and wall motion score (WMS) in patients with or without hyperglycemia. Both patients with hyperglycemia (open circles) and those without it (solid squares) showed a weak but significant relationship between peak CK and WMS (r = 0.35, p = 0.002 and r = 0.28, p = 0.04, respectively). The hyperglycemia group showed a significantly lower WMS, even after adjusting for differences in peak CK (p = 0.009 by analysis of covariance).
