Background: SYNTAX score (SS) was reported as an independent predictor for future cardiac events including target lesion revascularization and myocardial infarction. The aim of the study was to assess the relationship between SS and plaque characteristics as well as post-stenting vascular response evaluated by optical coherence tomography (OCT) in patients with stable angina.
Methods: A total of 179 lesions from 165 patients before stenting and 285 lesions from 262 patients after stenting were analyzed. Patients were divided into SS tertiles: 0.0 – 6.5 (1st tertile), 7.0 – 10.5 (2nd tentile), and more than 11.0 points (3rd tertile).
Results: In pre-stenting analysis, lesions in the 3rd tertile group, compared to the 1st tertile group, had higher plaque vulnerability and higher degree of calcification (Table). In post-stent implantation OCT, the incidence of stent edge dissection was higher in the 3rd tertile compared to the 1st tertile.
Conclusions: Our results may explain worse outcomes after coronary artery stenting in patients with higher SS.
