Abstract

Background: According to the literature, about one third of patients with brain ischemic symptoms lasting <24 hours, which are classified as TIAs according to the traditional "time-based" definition, show the presence of acute ischemic lesions at neuroimaging. Recent evidence has shown that the presence of acute ischemic lesions at neuroimaging may impact on the outcome of patients with transient ischemic symptoms treated with dual antiplatelet treatment (DAPT). This uncertainty is even more compelling in recent years as short-term DAPT has become the standard treatment for any non-cardioembolic TIA or minor ischemic stroke.

Methods: This is a pre-specified subgroup analysis from a prospective multicenter real-world study (READAPT). The analysis included patients with time-based TIA - i.e. those with ischemic symptoms lasting <24 hours - who started DAPT. In the whole population, we assessed the presence of acute brain ischemic lesions at neuroimaging and their association with the ABCD2 score. To assess the impact of acute brain ischemic lesions on 90-day prognosis, we performed a propensity score matching of patients with and without those lesions. We adopted a primary effectiveness outcome which was a composite of new stroke/TIA events and death due to vascular causes at 90 days.

Results: We included 517 patients - 324 (62.7%) male - with a median (interquartile range - IQR) age of 74 (IQR 65-81) years; 144 patients (27.9%) had acute brain ischemic lesions at neuroimaging. The proportion of patients with brain ischemic lesions did not vary according to the ABCD2 score. At follow-up, 4 patients with brain ischemic lesions (2.8%) and 21 patients without lesions (5.6%) reported the primary effectiveness outcome, which was similar between the groups before (p=0.178) and after matching (p=0.518).

Conclusions: In our population, patients with transient ischemic symptoms and acute ischemic lesions at brain MRI had a risk of recurrent ischemic events similar to those without lesions. The risk of recurrent ischemic events was low in both groups.

短暂性脑缺血症状与神经影像学检查中是否存在缺血性病变--READAPT 研究的结果。

背景：根据文献资料，约有三分之一的脑缺血症状患者持续存在方法：这是一项前瞻性多中心真实世界研究（READAPT）的预设亚组分析。分析包括基于时间的 TIA 患者，即缺血症状持续存在的患者：我们共纳入了 517 名患者，其中男性 324 名（62.7%），中位数（四分位数间距，IQR）年龄为 74 岁（IQR 65-81 岁）；144 名患者（27.9%）在神经影像学检查中发现急性脑缺血病变。脑缺血病变患者的比例并未因 ABCD2 评分的不同而有所差异。在随访中，4 名脑缺血病变患者（2.8%）和 21 名无病变患者（5.6%）报告了主要疗效结果，配对前（P=0.178）和配对后（P=0.518）两组间的结果相似：结论：在我们的研究人群中，有短暂性脑缺血症状和脑磁共振成像急性缺血性病变的患者发生复发性脑缺血事件的风险与无病变的患者相似。两组患者复发缺血事件的风险都很低。

期刊介绍： The International Journal of Stroke is a welcome addition to the international stroke journal landscape in that it concentrates on the clinical aspects of stroke with basic science contributions in areas of clinical interest. Reviews of current topics are broadly based to encompass not only recent advances of global interest but also those which may be more important in certain regions and the journal regularly features items of news interest from all parts of the world. To facilitate the international nature of the journal, our Associate Editors from Europe, Asia, North America and South America coordinate segments of the journal.
