AS [namely, augmentation pressure; augmentation index (AIx); and pulse wave velocity] was assessed using a validated oscillometric device (Mobil-O-Graph NG 24h PWA). Central arterial pressures were also recorded. In the cath lab, the number of puncture attempts, total procedural time (TPT), and largest catheter size were noted. If greater than two catheters were required to complete imaging, it was additionally specified. RAS was considered to exist if two or more of predefined clinical features were present.ResultsRAS was observed in 20 (16.3%) patients. Patients were divided into two distinct groups in terms of the occurence of RAS. In the RAS(+) group, the proportion of hypertensive individuals was significantly higher, whereas there were fewer smokers. With respect to operational data, TPT (24.39.8 vs. 29.3 +/- 9.1mins; P=0.038) and procedures carried out with more than one puncture attempts were significantly higher in the RAS(+) group. Among all oscillometric parameters, augmentation pressure, AIx, and PR were found to be higher in the RAS(+) group. According to multivariate analysis, TPT (P=0.029) and AIx (odds ratio: 1.044, 95% confidence interval=0.977-1.117; P=0.009) were found to be independent predictors of RAS.ConclusionAlong with conventional risk factors, AS assessment, as a practical, noninvasive method, may help to predict RAS in angiographic procedures.eninfo:eu-repo/semantics/embargoedAccessArterial StiffnessCoronary AngiographyPulse Wave AnalysisRadial ArteryArticle23525325910.1097/MBP.0000000000000340Q4Q1
