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.

Background and Purpose— Little was known about the predictive accuracy of the Essen Stroke Risk Score and the Stroke Prognostic Instrument II in Chinese patients with stroke. Methods— We evaluated the predictive accuracy of both Essen Stroke Risk Score and Stroke Prognostic Instrument II scores for both recurrent stroke and combined vascular events using data from a prospective cohort of 11 384 patients with acute ischemic stroke and transient ischemic attack admitted to 132 urban hospitals throughout China. Results— The cumulative 1-year event rates were 16% (95% CI, 15%–16%) for recurrent stroke and 18% (95% CI, 18%–19%) for combined vascular events. Both event rates were significantly higher in patients with transient ischemic attack and increased significantly from lower to higher Essen Stroke Risk Score and Stroke Prognostic Instrument II categories. Essen Stroke Risk Score and Stroke Prognostic Instrument II had similar predictive accuracies for each study outcome. Conclusions— In Chinese patients with ischemic stroke or transient ischemic attack, both Essen Stroke Risk Score and Stroke Prognostic Instrument II scores are equally able to stratify the risk of recurrent stroke and combined vascular events.

Background: The risk of stroke after cardiac and carotid surgery is well established. In contrast, stroke risk in association with non-cardiac and non-carotid surgery and its time course are insufficiently known. We investigated the prevalence of recent and planned surgery among patients with stroke and transient ischemic attack (TIA), time dependency of stroke risk, stroke etiology, and interruption of antithrombotic medication in association with surgery. Methods: Data on type and date of surgery and similar interventions within the last year or planned for the next 2 weeks were anonymously collected together with demographic data, vascular risk factors, stroke severity, handicap before stroke and stroke etiology within a state-wide, mandatory, hospital-based acute stroke care quality monitoring project (Rhineland-Palatinate, Germany) for 1 year (2010). Results: Non-carotid and non-cardiothoracic surgery was reported as performed within 1 year before the index event or as planned for the next 2 weeks thereafter in 532 out of 12,120 patients with ischemic stroke/TIA (4.4%). Compared to 91-365 days before stroke/TIA as reference period, risk of cerebral ischemia (per day analysis) was increased for surgery within 61-90 days before ischemia (rate ratio 2.0, 95% CI 1.5-2.8) and continuously increased along shorter intervals between stroke and surgery (31-60 days: rate ratio 3.6, 95% CI 2.9-4.5; 15-30 days: rate ratio 8.2, 95% CI 6.7-10.1; 8-14 days: rate ratio 13.2, 95% CI 10.3-16.8; 4-7 days: rate ratio 16.5, 95% CI 12.2-22.1) peaking at an interval of 1-3 days before ischemia (rate ratio 34.0, 95% CI 26.9-42.8). On the day of surgery, rate ratio was 14.8 (95% CI 7.8-27.9) and for planned surgery it was 2.7 (95% CI 1.8-4.0). Results were similar for first-ever and for recurrent ischemic stroke. Perioperative stroke/TIA was positively associated with atrial fibrillation and cardioembolic stroke etiology, higher mortality, more severe neurological deficits at discharge, and longer hospital stay; and it was inversely associated with microangiopathic etiology and discharge at home. In 34.5% of patients with recent/planned surgery, prior antithrombotic or anticoagulant medication had been interrupted. Conclusions: Recent or planned surgery imposes a considerable short-term stroke risk particularly by cardioembolism with cessation of medication as an important contributor. Stroke after surgery is associated with poor outcome and high mortality. Better strategies to reduce the burden of perioperative stroke are urgently required.

Background and Purpose: After ischemic stroke (IS) or transient ischemic attack (TIA), use of an antithrombotic agent to prevent recurrence is mandatory. However, antithrombotic agents rarely cause intracranial hemorrhage (ICH), frequently resulting in worse outcomes than recurrent IS. Cerebral microbleeds (CMBs) have been reported as a useful marker for finding ICH-prone patients. This retrospective study aimed to investigate the significance of CMB in the development of ICH in first-ever IS/TIA patients. Methods: The data source was our consecutive patient registry between 2005 and 2015. Patients with stroke/TIA admitted to our hospital more than twice (first as first-ever IS/TIA and second or later as recurrent IS/TIA or ICH) and underwent head MRI including T2*-weighted imaging on the first admission were extracted. Clinical characteristics including use of antithrombotic therapy and distribution of CMB on the first and second admissions were compared between recurrent IS/TIA and ICH groups. Distribution of CMB was divided into deep, lobar, or both. Results: In total, 708 IS/TIA patients (second stroke: 640 IS/TIA; 68 ICH) were extracted. The ICH group showed a longer period until second stroke (1,062 days vs. 817 days, p=0.022) and higher mean NIHSS score (14.8 vs. 6.1, p<0.001) on second admission than the IS/TIA group. On first admission, the ICH group had a higher frequency of CMB (72.1% vs. 49.5%, p<0.001) and lower frequency of cardioembolism (14.7% vs. 25.8%, p=0.044) than the IS/TIA group. About half of hemorrhages occurred in similar locations of the CMB depicted on first admission. A higher frequency of ICH was observed in patients with deep CMB (11.3% vs. 5.6%, p=0.022) or both deep and lobar CMBs (17.4% vs. 5.6%, p<0.001) than in those without CMB. Use of anticoagulants was a significant risk factor for transition from first IS/TIA to second ICH (odds ratio [95% confidence interval]: 3.75 [1.30-10.8], adjusted by sex, age, type of first stroke, and CMB location). Conclusions: This study found IS/TIA patients with CMB are at high risk of ICH compared to patients without CMB. Preventive antithrombotic treatment particularly use of anticoagulants for CI/TIA patients with CMB should be provided under careful monitoring for the risk of hemorrhage.

The Impact

Background and Purpose— The recent redefinition of transient ischemic attack (TIA) reclassifies patients with acute infarction on magnetic resonance imaging as ischemic stroke. Redefinition will improve the prognosis of both TIA and ischemic stroke, an epidemiological paradox known as the Will Rogers phenomenon. We sought to quantify the impact of this phenomenon. Methods— Incidence of TIA, risk of death/disability after stroke, rate of acute infarction on magnetic resonance imaging after TIA, and 90-day stroke risk after TIA with and without infarction on magnetic resonance imaging were determined based on published data. The impact on poststroke disability in the redefined cohort of patients with ischemic stroke was computed. A sensitivity analysis was performed to account for uncertainty in input variables. Results— Using the new TIA definition, the 90-day risk of stroke following TIA is 1%. In the United States, redefinition will increase annual ischemic stroke incidence from 691 650 to 747 755 and result in a 3.4% absolute reduction in poststroke disability. In a sensitivity analysis, this risk reduction varies from 1.5 to 6.5%, and is most dependent on the incidence of TIA. Conclusions— Redefinition of TIA reduces stroke risk after TIA to approximately 1% at 90 days, and reduces the rate of poststroke disability by approximately 3.4%.
