Abstract
AbstractBackgroundImaging modality‐based evidence is limited that compares the extent of coronary arterial repair after percutaneous coronary intervention between patients with stable angina pectoris (SAP) and those with acute coronary syndrome (ACS).MethodsBetween December 2018 and November 2021, a single‐center, nonrandomized, observational study was conducted in 92 patients with SAP (n = 42) or ACS (n = 50), who were implanted with Orsiro sirolimus‐eluting stent (O‐SES) providing a hybrid (active and passive) coating and underwent 1‐year follow‐up by coronary angioscopy (CAS) after implantation. CAS assessed neointimal coverage (NIC), maximum yellow plaque (YP), and mural thrombus (MT).ResultsBaseline clinical characteristics were comparable between the SAP and ACS groups. The follow‐up periods were comparable between the two groups (390.1 ± 69.9 vs. 390.6 ± 65.7 days, p = 0.99). The incidences of MT at 1 year after implantation were comparable between the two groups (11.4% vs. 11.1%, p = 0.92). The proportions of “Grade 1” in dominant NIC grades were highest in both groups, and the proportions of maximum YP grades and MT were comparable between the two groups.ConclusionO‐SES‐induced coronary arterial repair at the site of stent implantation, irrespective of the types of coronary artery disease.
