Ischemic Attack

Stroke embodies one of the leading causes of death and disability worldwide. We aimed to provide a comprehensive insight into the effectiveness and safety of antiplatelet agents and anticoagulants in the secondary prevention of ischemic stroke or transient ischemic attack. A systematic search for randomized controlled trials, comparing antiplatelet or anticoagulant therapy versus aspirin or placebo among patients with ischemic stroke or transient ischemic attack, was performed in order to summarize data regarding the different regimens. Keyword-based searches in the MEDLINE, EMBASE, and Cochrane Library databases were conducted until the 1st of January 2021. Our search explored 46 randomized controlled trials involving ten antiplatelet agents, six combinations with aspirin, and four anticoagulant therapies. The review of the literature reflects that antiplatelet therapy improves outcome in patients with ischemic stroke or transient ischemic attack. Monotherapy proved to be an effective and safe choice, especially in patients with a high risk of bleeding. Intensified antiplatelet regimens further improve stroke recurrence; however, bleeding rate increases while mortality remains unaffected. Supplementing the clinical judgment of stroke treatment, assessment of bleeding risk is warranted to identify patients with the highest benefit of treatment intensification.

Quality Evidence

Background and Purpose: Approximately 30% of ischemic strokes occur after a previous stroke or transient ischemic attack. Arterial hypertension is one of the best established risk factors for first and recurrent stroke, both ischemic and hemorrhagic. Guidelines for the secondary prevention of ischemic stroke support the use of blood pressure (BP)–lowering drugs in most patients. However, the evidence for these recommendations comes from meta-analyses that included both ischemic and hemorrhagic stroke patients, whereas these 2 conditions differ quantitatively in several aspects. With this systematic review and meta-analysis, we aimed at summarizing the current evidence on BP-lowering drugs for secondary prevention in patients with ischemic stroke or transient ischemic attack. Methods: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials up to January 31, 2020. We included randomized controlled trials comparing any specific BP-lowering drug, as monotherapy or combination, with either a control or another BP-lowering drug. Results: Eight studies that enrolled 33 774 patients with ischemic stroke or transient ischemic attack were included in the meta-analysis. Mean follow-up was 25 months (range, 3–48). Moderate-quality evidence indicated that a subsequent stroke occurred in 7.9% (ischemic in 7.4% or hemorrhagic in 0.6%) of patients taking any type of BP-lowering drug compared with 9.7% of patients taking placebo (odds ratio, 0.79 [95% CI, 0.66–0.94]; absolute risk difference, −1.9% [95% CI, −3.1% to −0.5%]). Moderate-quality evidence indicated that mortality occurred similarly in patients taking any type of BP-lowering treatment compared with placebo, with an absolute risk of 7.3% and 7.9%, respectively (odds ratio, 1.01 [95% CI, 0.92–1.10]; absolute risk difference, 0.1% [95% CI, −0.6% to 0.7%]). Conclusions: The use of BP-lowering drugs in patients with ischemic stroke or transient ischemic attack is associated with a 1.9% risk reduction of stroke but does not affect the all-cause mortality risk.

Ischemic Attack

Ischemic stroke and transient ischemic attack (TIA) are the most common cerebrovascular disorder and leading cause of death in China. The Effective secondary prevention is the vital strategy for reducing stroke recurrence. The aim of this guideline is to provide the most updated evidence-based recommendation to clinical physicians from the prior version. Control of risk factors, intervention for vascular stenosis/occlusion, antithrombotic therapy for cardioembolism, and antiplatelet therapy for noncardioembolic stroke are all recommended, and the prevention of recurrent stroke in a variety of uncommon causes and subtype provided as well. We modified the level of evidence and recommendation according to part of results from domestic RCT in order to facility the clinical practice.

Ischemic Attack

Background: Evidence about the use of dual antiplatelet therapy (DAPT) with aspirin and P2Y12 inhibitors in patients with acute minor ischemic stroke or transient ischemic attack (TIA) is emerging. The aim of our study was to provide an updated and comprehensive analysis about the risks and benefits of DAPT versus aspirin monotherapy in this setting. Methods: The PubMed, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov databases, main international conference proceedings were searched for randomized controlled trials comparing DAPT versus aspirin monotherapy in patients with acute ischemic stroke or TIA not eligible for thrombolysis or thrombectomy presenting in the first 24 hours after the acute event. Data were pooled by meta-analysis using a random-effects model. The primary efficacy endpoint was ischemic stroke recurrence, and the primary safety outcome was major bleeding. Secondary endpoints were intracranial hemorrhage, hemorrhagic stroke, and all-cause death. Results: A total of 4 studies enrolling 21,459 patients were included. DAPT with clopidogrel was used in 3 studies, DAPT with ticagrelor in one study. DAPT duration was 21 days in one study, 1 month in one study, and 3 months in the remaining studies. DAPT was associated with a significant reduction in the risk of ischemic stroke recurrence (relative risk [RR], 0.74; 95% confidence interval [CI], 0.67-0.82, P<0.001, number needed to treat 50 [95% CI 40-72], while it was associated with a significantly higher risk of major bleeding (RR, 2.59; 95% CI 1.49-4.53, P=0.001, number needed to harm 330 [95% CI 149-1111]), of intracranial hemorrhage (RR 3.06, 95% CI 1.41-6.66, P=0.005), with a trend towards higher risk of hemorrhagic stroke (RR 1.83, 95% CI 0.83-4.05, P=0.14), and a slight tendency towards higher risk of all-cause death (RR 1.30, 95% CI 0.89-1.89, P=0.16). Conclusions: Among patients with acute minor ischemic stroke or TIA, DAPT, as compared with aspirin monotherapy, might offer better effectiveness in terms of ischemic stroke recurrence at the expense of a higher risk of major bleeding. The trade-off between ischemic benefits and bleeding risks should be assessed in tailoring the therapeutic strategies.
