The purpose of this study was to investigate the impact of pullback speed on evaluation of lipid core plaque using the latest generation NIRS-IVUS catheter. Patients with coronary artery disease who underwent coronary angiography or percutaneous coronary intervention with NIRS-IVUS examination at 2 different pullback speeds (0.5 and 2.0 mm/sec) for the same vessel were enrolled. The values of lipid core burden index (LCBI) and maxLCBI4mm were compared between the images recorded with pullback speeds of 0.5 and 2.0 mm/sec, and match or mismatch of the location where maxLCBI4mm was detected was investigated. In a total of 286 NIRS-IVUS image sets, the location of maxLCBI4mm measured at 0.5 and 2.0 mm/sec was mismatched in 81 (28.3%) image sets. In comparison by vessel type, 20.8% were mismatched in LAD, 31.1% in LCx, and 37.8% in RCA (p = 0.023). In 205 image sets with matched maxLCBI4mm location, the maxLCBI4mm value at 2.0 mm/sec was significantly greater compared with that at 0.5 mm/sec (348.0 vs. 302.0 in median, p < 0.001). In a substantial proportion of patients, the location of maxLCBI4mm values measured at 0.5 and 2.0 mm/sec was mismatched. In the image sets with matched maxLCBI4mm location, the maxLCBI4mm value at 2.0 mm/sec was significantly greater compared with that at 0.5 mm/sec. These results should be noted when applying the cut-off values of maxLCBI4mm recorded at 2.0 mm/sec.</p>","PeriodicalId":9439,"journal":{"name":"Cardiovascular Intervention and Therapeutics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143771276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major adverse cardiac events (MACE) and mortality were assessed from bleeding until 3 years after PCI.

The aim of this observational, retrospective analysis was to close this lack of evidence. Between January 2007 and February 2021, a total of 3511 patients with 5497 in-stent restenosis (ISR) lesions were treated at two large-volume centers in Munich, Germany, of which 763 (21.7%) were female. Endpoints of interest were all-cause mortality and rates of repeat revascularization. Outcomes are presented as Kaplan-Meier event rates. Univariate and multivariate analyses were performed. Female patients were older (72.1 ± 10.4 versus 68.4 ± 10.4 years, p < 0.001) and suffered more often from diabetes (38.8% versus 34.4%, p = 0.029). There was no statistical difference regarding the clinical presentation and interventional treatment strategy. After 10 years, the risk of all-cause mortality was higher in female patients [hazard ratio (HR) 1.18 (1.02-1.35); p = 0.022]; however, after adjustment for age, the risk did not differ significantly between both sexes [adjusted HR 0.96 (0.83-1.11); p = 0.6]. Regarding target vessel revascularization (TVR) and non-target vessel revascularization (NTVR), the risk was lower in female patients [HR 0.73 (0.61-0.87); p < 0.001 and HR 0.74 (0.64-0.86); p < 0.001] even after age adjustment. No statistical differences were found regarding the risk of target lesion revascularization, target vessel myocardial infarction and stent thrombosis.
