Authors' conclusion

Intracoronary imaging-derived plaque features are significantly associated with future cardiovascular events. Multiparametric models integrating compositional and morphological features apparently enhance risk stratification compared with single parameters.

Study context

Population
Patients with untreated coronary lesions assessed by optical coherence tomography (OCT) or intravascular ultrasound (IVUS) for plaque vulnerability featurespatients in 12 studies, 22,319 lesions
Participants
8,453 patients
Comparison
prognostic impact of plaque vulnerability features assessed by OCT or IVUS
Outcome
study-defined MACE

Pooled result

As reported in the abstract

Hazard ratio (95% CI)
thin-cap fibroatheroma (TCFA)lower positive association among predictors
3.06(1.97–4.77)
plaque burdenhighest association among predictors
3.92(1.45–10.59)

Further pooled results

Imaging modality comparison

IVUS-derived parameters (minimum lumen area and high-risk plaque definition) were superior to their OCT counterparts, whereas OCT better discriminated prognostic thin-cap fibroatheroma (TCFA)

Combined parameters

The combination of minimum lumen area, TCFA and lipid arc yielded the strongest predictive performance for MACE risk
