Figure 4

Upper panel. This bar graph shows the ratio of external to internal VV in the four different groups. The non-calcified stenotic plaque segments showed a significant higher ratio compared to normal segments.

Lower panel. Correlation between VV density and calcium area in about four cross sections per coronary artery segment containing a calcified plaque. There was a moderate, negative correlation between VV density and calcium area in selected cross sections (r=0.42). * P<0.001
