The aim is to review transient ischaemic attack (TIA) clinics, other service delivery models, and current TIA management.
Urgent assessment of TIA patients by stroke specialist services reduces stroke risk and is cost-effective. Almost one-third of TIA patients wait more than 24 h before presenting to medical attention, with delay associated with higher stroke risk. Risk stratification following suspected TIA may be performed by clinical assessment of individual patient characteristics, combined with the validated ABCD2 score (pre-investigation), and the ABCD3-I score (postinvestigation) in secondary care settings. Brain MRI and transcranial Doppler ultrasound add information related to vascular territory, TIA mechanism, and prognosis. Variability in systolic blood pressure in treated and untreated patients is an important predictor of stroke risk, independently of mean blood pressure.
Daily specialist-provided TIA services delivered in clinic or inpatient settings have proven efficacy for stroke prevention. In addition, a rapid-access, clinic-based service is associated with cost savings and reduced hospital bed-day utilization after TIA.
目的是综述短暂性脑缺血发作(TIA)诊所、其他服务提供模式和当前 TIA 管理。
由卒中专家服务对 TIA 患者进行紧急评估可降低卒中风险且具有成本效益。近三分之一的 TIA 患者在出现症状后超过 24 小时才到医疗机构就诊,而就诊延迟与更高的卒中风险相关。疑似 TIA 患者的风险分层可通过个体患者特征的临床评估来进行,结合 ABCD2 评分(预调查)和 ABCD3-I 评分(后调查)在二级医疗机构进行。脑 MRI 和经颅多普勒超声可提供与血管区域、TIA 机制和预后相关的信息。治疗和未治疗患者的收缩压变异性是卒中风险的重要预测指标,独立于平均血压。
在诊所或住院环境中提供的每日专家 TIA 服务已被证明可有效预防卒中。此外,基于诊所的快速就诊服务与 TIA 后成本节约和减少医院床位日利用相关。
