Plaque types - SRP and SNP.
There were no significant differences in the incidence of all plaques types in SRP an SNP with IVUS (Table 1).

CTCA.
SRP and SNP.
The most of CTCA-plaque features (plaque length,
positive remodeling,
remodeling index,
spotty calcinates,
low density area) were not different in SRP and SNP groups.
Only two CTCA -features (irregular surface and “nupkin-ring”) were significantly different in SRP and SNP groups,
p<0,05 (Table 2).
