How are coronary artery stenoses reported?
Coronary artery plaques are described by:
- • The vessel and the vessel segment.
- • Plaque composition (i.e., calcified, mixed, or noncalcified).
- • Plaque length.
- • Degree of stenosis.
Degree of stenosis is best characterized by percentage values (e.g., “50%” stenosis). A percentage is more specific than qualitative descriptors such as “moderate,” although the precision with which stenoses can be measured will depend on study quality.
