Figure 1 Comparisons of IB-IVUS Parameters Among the 3 Groups
(A) Percentage of lipid volume (%LV). (B) Percentage of fibrous volume (%FV). (C) Percentage of high signal volume. Coronary arteries in patients with impaired glucose resistance (IGR) and diabetes mellitus (DM) significantly increased in %LV (37 ± 13% and 36 ± 14% vs. 29 ± 14%, p = 0.02) and significantly decreased in %FV (58 ± 11% and 59 ± 11% vs. 64 ± 11%, p = 0.03) compared with those with normal glucose regulation (NGR). ANOVA = analysis of variance; IB-IVUS = integrated backscatter intravascular ultrasound.
