Factors associated with acute myocardial infarction after index carotid artery stenting (multivariate Cox regression with forward stepwise selection).

ARF = acute renal failure; COPD = chronic obstructive pulmonary disease; HR = hazard ratio; CI = confidence interval; NA = not applicable;† defined as ≥43 volume per year;The model was fully adjusted for the listed variables.Factors associated with acute myocardial infarction after index carotid artery stenting (multivariate Cox regression with forward stepwise selection).

ARF：急性肾衰竭（acute renal failure）；COPD：慢性阻塞性肺疾病（chronic obstructive pulmonary disease）；HR：风险比（hazard ratio）；CI：置信区间（confidence interval）；NA：不适用（not applicable）；† 定义为每年≥43个容量单位；本模型已针对所列变量进行完全校正。本研究分析首次颈动脉支架置入术后急性心肌梗死的相关影响因素（采用向前逐步选择法的多变量Cox回归分析）。
