Figure 2 Presence of Different Plaque Types in the Various Patient Groups

Patients with multivessel disease presented with relatively more mixed (55%) and less noncalcified plaques (30%) as compared with patients with nonobstructive coronary artery disease (CAD) and patients with single-vessel CAD. The prevalence of calcified plaques remained constant between the 3 groups (nonobstructive CAD: 12% vs. single-vessel CAD: 14% vs. multivessel CAD: 15%). Open bars = noncalcified plaques; hatched bars = mixed plaques; solid bars = calcified plaques.
