Exploration of factors affecting prognosis of stroke preceded by transient ischemic attack

Background: Age is the most important risk factor for stroke. The regional brain affection was not considered in a comparison between different brain locations as a predictor for outcome in those with and without prior TIA.Aims and Objectives: Can transient Ischemic attack predict stroke prognosis?Materials and Methods: Fifty nine patients, aged ≥ 55 years old, with recent ischemic stroke were studied, with (cases, 40.68%) and without (controls) antecedent TIA. National Institutes of Health Stroke Scale (NIHSS), modified Rankin scale (MRS), and California risk score (CRS) were assessed. A brain computed tomography was done.Results: Older age was a predictor of more severe stroke (P<0.001). Different latencies for TIA were studied. With reference to our controls, better prognosis was found only in cases with TIA ≤ seven days as a predictor for better NIHSS and MRS. In cases, CRS was a significant predictor of shorter latency. Infratentorial ischemic stroke, not supratentorial ischemic stroke, with prior TIA, was a significant predictor of lower NIHSS.Conclusion: TIA ≤ seven days is a predictor for better NIHSS and MRS.Asian Journal of Medical Sciences Vol.7(4) 2016 68-74

Background: We aimed to clarify associations between pre-admission risk scores (CHADS2, CHA2DS2-VASc, and HAS-BLED) and 2-year clinical outcomes in ischemic stroke or transient ischemic attack (TIA) patients with non-valvular atrial fibrillation (NVAF) using a prospective, multicenter, observational registry. Methods: From 18 Japanese stroke centers, ischemic stroke or TIA patients with NVAF hospitalized within 7 days after onset were enrolled. Outcome measures were defined as death/disability (modified Rankin Scale score ≥3) at 2 years, 2-year mortality, and ischemic or hemorrhagic events within 2 years. Results: A total of 1,192 patients with NVAF (527 women; mean age, 78 ± 10 years), including 1,141 ischemic stroke and 51 TIA, were analyzed. Rates of death/disability, mortality, and ischemic or hemorrhagic events increased significantly with increasing pre-admission CHADS2 (p for trend <0.001 for death/disability and mortality, p for trend = 0.024 for events), CHA2DS2-VASc (p for trend <0.001 for all), and HAS-BLED (p for trend = 0.004 for death/disability, p for trend <0.001 for mortality, p for trend = 0.024 for events) scores. Pre-admission CHADS2 (OR per 1 point, 1.52; 95% CI 1.35–1.71; p <0.001 for death/disability; hazard ratio (HR) per 1 point, 1.23; 95% CI 1.12–1.35; p <0.001 for mortality; HR per 1 point, 1.14; 95% CI 1.02–1.26; p = 0.016 for events), CHA2DS2-VASc (1.55, 1.41–1.72, p < 0.001; 1.21, 1.12–1.30, p < 0.001; 1.17, 1.07–1.27, p < 0.001; respectively), and HAS-BLED (1.33, 1.17–1.52, p < 0.001; 1.23, 1.10–1.38, p < 0.001; 1.18, 1.05–1.34, p = 0.008; respectively) scores were independently associated with all outcome measures. Conclusions: In ischemic stroke or TIA patients with NVAF, all pre-admission risk scores were independently associated with death/disability at 2 years and 2-year mortality, as well as ischemic or hemorrhagic events within 2 years.

We reported a case of acute embolic occlusion of the middle cerebral artery with a patent accessory middle cerebral artery. Because of the presence of sufficient collateral blood supply from the accessory middle cerebral artery, the patient only underwent transient ischemic attack and did not need endovascular treatment. There was mild infarction in the basal ganglia and temporal lobe, NIHSS score of the patient at discharge seven days after stroke onset was 0, and modified Rankin scale score at 90 days was 0.

Background and Purpose: Although endovascular treatment (EVT) for acute ischemic stroke is classified as I evidence, outcomes after EVT in real-world practice appear to be less superior than those in randomized clinical trials (RCTs). Additionally, the effect of EVT is unclear compared with medical treatment (MT) for patients with mild symptoms defined by National Institutes of Health Stroke Scale score <6 or with severe symptoms defined by Alberta Stroke Program Early CT Score <6. Methods: Literatures were searched in big databases and major meetings from December 6, 2009, to December 6, 2019, including RCTs and observational studies comparing EVT against MT for patients with acute ischemic stroke. Observational studies were precategorized into 3 groups based on imaging data on admission: mild stroke group with National Institutes of Health Stroke Scale score <6, severe stroke group with Alberta Stroke Program Early CT Score <6 or ischemic core ≥50 mL, and normal stroke group for all others. Outcome was measured as modified Rankin Scale score of 0 to 2, mortality at 90 days, and symptomatic intracranial hemorrhage (sICH) at 24 hours. Results: Fifteen RCTs (n=3694) and 37 observational studies (n=9090) were included. EVT was associated with higher modified Rankin Scale 0 to 2 rate and lower mortality in RCTs and normal stroke group, whereas EVT was associated with higher sICH rate in normal stroke group, and no difference of sICH rate appeared between EVT and MT in RCTs. In severe stroke group, EVT was associated with higher modified Rankin Scale 0 to 2 rate and lower mortality, whereas no difference of sICH rate was found. In mild stroke group, there was no difference in modified Rankin Scale 0 to 2 rate between EVT and MT, whereas EVT was associated with higher mortality and sICH rate. Conclusions: Evidence from RCTs and observational studies supports the use of EVT as the first-line choice for eligible patients corresponding to the latest guideline. For patients with Alberta Stroke Program Early CT Score <6, EVT showed superiority over MT, also in line with the guidelines. On the contrary to the guideline, our data do not support EVT for patients with National Institutes of Health Stroke Scale score <6.

Ischemic Attack

Background and Purpose— Intraluminal thrombus (ILT) is an uncommon finding among patients with ischemic stroke. We report clinical-imaging manifestations, treatment offered, and outcome among patients with ischemic stroke/transient ischemic attack and ILT in their cervico-cephalic arteries. Methods— Sixty-one of 3750 consecutive patients with acute ischemic stroke/transient ischemic attack (within 24 hours of onset) and ILT on initial arch-to-vertex computed tomography angiography from April 2015 through September 2017 constituted the prospective study cohort. Functional outcome was assessed using the modified Rankin Scale score with functional independence at discharge defined as modified Rankin Scale score ≤2. Results— Prevalence of ILT on computed tomography angiography was 1.6% (95% CI, 1.2%–2.1%). Median age was 67 years (interquartile range, 56–73), and 40 subjects (65%) were male. The initial clinical presentation included transient ischemic attack in 12 (20%) and stroke in 49 patients (80%); most strokes (76%) were mild (National Institutes of Health Stroke Scale ≤5). The most common ILT location was cervical carotid or vertebral artery (n=48 [79%]) followed by intracranial (n=11 [18%]) and tandem lesions (n=2 [3%]). The most common initial treatment strategy was combination antithrombotics (heparin with single antiplatelet agent) among 57 patients (93%). Follow-up computed tomography angiography (n=59), after a median 6 days (interquartile range 4–10 days), revealed thrombus resolution in 44 patients (75% [completely in 27%]). Twenty four of 30 patients (80%) with >50% residual carotid stenosis underwent carotid revascularization (endarterectomy in 15 and stenting in 9 patients) without peri-procedural complications a median of 9 days after symptom onset. In-hospital stroke recurrence occurred in 4 patients (6.6%). Functional independence was achieved in 46 patients (75%) at discharge. Conclusions— Patients presenting with acute stroke/transient ischemic attack with ILT on baseline imaging have a favorable clinical course in hospital with low stroke recurrence, high rate of thrombus resolution, and good functional outcome when treated with combination antithrombotic therapy.

Severe Stroke

Background: Clopidogrel reduces the risk of non-cardioembolic ischemic stroke, but it is unclear whether it affects the severity and outcome of stroke. We aimed at evaluating the effect of prior treatment with clopidogrel on acute non-cardioembolic ischemic stroke severity and in-hospital outcome. Methods: We prospectively studied 608 consecutive patients (39.5% males, age 79.1 ± 6.6 years) who were admitted with acute ischemic stroke. The severity of stroke was assessed at admission with the National Institutes of Health Stroke Scale (NIHSS). Severe stroke was defined as NIHSS ≥21. The outcome was assessed using the dependency rates that prevailed at the time of discharge (i.e. modified Rankin scale between 2 and 5) and with in-hospital mortality. Results: At admission, 397 patients did not have atrial fibrillation or heart valve disease. Among these 397 patients, 69 were receiving monotherapy with clopidogrel prior to stroke, 69 were receiving monotherapy with aspirin and 236 patients were not on any antiplatelet treatment. The prevalence of severe stroke was lower in patients who were receiving clopidogrel than in patients who were receiving aspirin and patients who were not on antiplatelets (1.4, 13.0 and 11.0%, respectively; p < 0.05). Independent predictors of severe stroke at admission were male gender (relative risk (RR) 0.31, 95% CI 0.12-0.78, p < 0.05) and treatment with clopidogrel prior to stroke compared with no antiplatelet treatment (RR 0.13, 95% CI 0.02-0.97, p < 0.05). Treatment with aspirin prior to stroke did not predict severe stroke compared with no antiplatelet treatment (RR 1.24, 95% CI 0.51-2.98, p = NS). The rate of dependency at discharge did not differ between patients who were receiving clopidogrel, patients who were receiving aspirin and those who were not on antiplatelets (57.9, 47.8 and 59.7%, respectively; p = NS). Independent predictors of dependency at discharge were age (RR 1.12, 95% CI 1.05-1.19, p < 0.001) and NIHSS at admission (RR 1.67, 95% CI 1.46-1.92, p < 0.001). In-hospital mortality rate also did not differ between patients who were receiving clopidogrel, patients who were receiving aspirin and those who were not on antiplatelets (4.3, 4.3 and 5.0%, respectively; p = NS). The only independent predictor of in-hospital mortality was NIHSS at admission (RR 1.22, 95% CI 1.14-1.30, p < 0.001). Conclusions: Treatment with clopidogrel prior to acute non-cardioembolic ischemic stroke attenuates the severity of stroke at admission but does not appear to affect the functional outcome at discharge or the in-hospital mortality of these patients.

Peripheral Arterial

Background: Peripheral arterial disease (PAD) is frequently present in patients with acute ischemic stroke. However, there are limited data regarding the association between ankle brachial index (ABI) ≤ 0.90 (which is diagnostic of PAD) or > 1.40 (suggesting calcified arteries) and the severity of stroke and in-hospital outcome in this population. We aimed to evaluate these associations in patients with acute ischemic stroke. Patients and methods: We prospectively studied 342 consecutive patients admitted for acute ischemic stroke (37.4 % males, mean age 78.8 ± 6.4 years). The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS) at admission. The outcome was assessed with the mRS and dependency (mRS 2 - 5) at discharge and in-hospital mortality. Results: An ABI ≤ 0.90 was present in 24.6 % of the patients whereas 68.1 % had ABI 0.91 - 1.40 and 7.3 % had ABI > 1.40. At admission, the NIHSS score did not differ between the 3 groups (10.4 ± 10.6, 8.3 ± 9.3 and 9.3 ± 9.4, respectively). The mRS score was also comparable in the 3 groups (3.6 ± 1.7, 3.1 ± 1.8 and 3.5 ± 2.3, respectively). At discharge, the mRS score did not differ between the 3 groups (2.9 ± 2.2, 2.3 ± 2.1 and 2.7 ± 2.5, respectively) and dependency rates were also comparable (59.5, 47.6 and 53.3 %, respectively). In-hospital mortality was almost two-times higher in patients with ABI ≤ 0.90 than in patients with ABI 0.91 - 1.40 or > 1.40 but this difference was not significant (10.9, 6.6 and 6.3 %, respectively). Conclusions: An ABI ≤ 0.90 or > 1.40 does not appear to be associated with more severe stroke or worse in-hospital outcome in patients with acute ischemic stroke.
