摘要: Background Although drug-coated balloon (DCB) angioplasty is a well-established drug-eluting stent (DES) in-stent restenosis (ISR) strategy, there are minimal data regarding the association of neointimal burden on optical coherence tomography (OCT) before and after DCB adverse clinical events. This study aimed to investigate impact measured with OCT in patients DES ISR angioplasty. Methods From 2010 through 2013, total 122 lesions were treated DCB, which was preceded followed by examination. Major cardiac events (MACE, composite occurrence cardiovascular death, nonfatal myocardial infarction [MI], or target lesion revascularization [TLR]) evaluated. Results MACE occurred 27 (4 MIs 23 TLRs) during follow-up (median: 55.3 months, interquartile range 43.1-66.0). The mean lumen area significantly smaller (3.21 ± 2.42 mm2 vs. 4.80 2.53 , p = .005) percentage volume derived greater (49.3 9.2% 38.3 17.5%, .006) pre-procedural (cut-off 50%, under receiver operating characteristic [ROC] curve 0.644, 95% confidence interval [CI] 0.531-0.758, .022) post-procedural 25%, ROC 0.659, CI 0.546-0.773, .012) identified as significant parameters predict MACE. Conclusion OCT-derived percentages can be important for predicting future ISR.
