Résumé
Although an in vivo diagnosis of coronary plaque erosion has become possible by optical coherence tomography (OCT), angiographic characteristics of erosion have not been studied. The aim of this study was to investigate the angiographic features of plaque erosion in patients with non-ST elevation acute coronary syndromes (NSTE-ACS). Patients with NSTE-ACS who underwent OCT of the culprit lesion were collected at 11 institutions from 6 countries. Patients were classified as erosion or non-erosion based on OCT images. Angiographic features of both groups were compared. Among 494 cases with NSTE-ACS, 242 had plaque erosion and 252 had non-erosion. Compared to non-erosion group, erosion patients had less multivessel disease (28.5% vs. 49.6%, p < 0.001), lower Jeopardy score (4.2 vs. 5.0, p < 0.001), lower Gensini score (21.3 vs. 25.6, p = 0.014), and lower Syntax score (8.9 vs. 11.5, p < 0.001). With regard to the culprit lesion morphology, plaque erosion group had smaller reference diameter (2.8 mm vs. 3.0 mm, p = 0.032), less frequent type B2/C lesions (51.2% vs. 71.8%, p < 0.001), and lower prevalence of calcification (4.1% vs. 13.9%, p < 0.001) and thrombus (16.5% vs. 28.2%, p = 0.002). In the mid left anterior descending artery (LAD), erosion was significantly more frequent than non-erosion (30.2% vs. 21.8%, p = 0.034). Patients with NSTE-ACS caused by plaque erosion have less complex angiographic features both at the 3-vessel level and at the culprit lesion level. Plaque erosion was frequently found in the mid LAD.

BACKGROUND
Although an in vivo diagnosis of coronary plaque erosion has become possible by optical coherence tomography (OCT), angiographic characteristics of erosion have not been studied. The aim of this study was to investigate the angiographic features of plaque erosion in patients with non-ST elevation acute coronary syndromes (NSTE-ACS).
METHODS
Patients with NSTE-ACS who underwent OCT of the culprit lesion were collected at 11 institutions from 6 countries. Patients were classified as erosion or non-erosion based on OCT images. Angiographic features of both groups were compared.
RESULTS
Among 494 cases with NSTE-ACS, 242 had plaque erosion and 252 had non-erosion. Compared to non-erosion group, erosion patients had less multivessel disease (28.5% vs. 49.6%, p < 0.001), lower Jeopardy score (4.2 vs. 5.0, p < 0.001), lower Gensini score (21.3 vs. 25.6, p = 0.014), and lower Syntax score (8.9 vs. 11.5, p < 0.001). With regard to the culprit lesion morphology, plaque erosion group had smaller reference diameter (2.8 mm vs. 3.0 mm, p = 0.032), less frequent type B2/C lesions (51.2% vs. 71.8%, p < 0.001), and lower prevalence of calcification (4.1% vs. 13.9%, p < 0.001) and thrombus (16.5% vs. 28.2%, p = 0.002). In the mid left anterior descending artery (LAD), erosion was significantly more frequent than non-erosion (30.2% vs. 21.8%, p = 0.034).
CONCLUSIONS
Patients with NSTE-ACS caused by plaque erosion have less complex angiographic features both at the 3-vessel level and at the culprit lesion level. Plaque erosion was frequently found in the mid LAD.
