Macrophage Density in Lipid-Rich Plaques

Macrophage Density (%)STEMI (n = 49)UAP (n = 46)SAP (n = 24)p Value
All (n = 119)5.54 ± 1.485.86 ± 2.014.14 ± 1.81<0.001
Culprit (n = 76)5.66 ± 1.445.91 ± 2.064.21 ± 1.740.011
Remote (n = 43)5.38 ± 1.565.76 ± 1.954.02 ± 2.020.076

Values are presented as mean ± SD. Differences between groups determined using analysis of variance. No significant difference was detected between the macrophage density at the culprit and remote lesions within each clinical group.

UAP = unstable angina pectoris; other abbreviations as in Table 1.
