Background: Age is a strong predictor of outcomes following acute ischemic stroke (AIS). Conflicting data exist on whether endovascular reperfusion therapy (ERT) should be offered to patients over 80 years of age. We compared the safety and efficacy of ERT in elderly (> 80 years) compared to non-elderly (< 80 years) patients with AIS. Methods: We collected data from a large multi-center prospective registry of AIS patients treated with ERT. Data were available on demographics, initial severity, angiographic results, hemorrhagic complications using the ECASS criteria, and 3-month functional outcomes using the modified Rankin Scale (mRS). The thrombolysis in myocardial infarction (TIMI) score was used to grade reperfusion. We compared baseline factors, procedural results, and clinical outcomes in those over > 80 years versus those < 80 years. P-value < 0.05 was considered significant. Results: Among 1077 patients with anterior circulation AIS, 223 (20.7%) were > 80 years. Elderly patients were more likely to have atrial fibrillation (54.3% vs. 31.4%, P < 0.001) but less likely to have diabetes (16.1% vs. 24.6%; P=0.046) or smoking (13.2% vs. 32.6%, P<0.001) history. Both groups were similar in other baseline factors, initial NIHSS score, location of occlusions, time from onset to groin puncture. TIMI 2 or 3 reperfusion was achieved in 64.5% of those > 80 vs. 70.7% in those < 80 (P=0.080). Rates of symptomatic hemorrhage and any intracranial hemorrhage were not different between groups. Good outcome at 3 months (mRS 0-2) was noted in 16.5% of elderly compared to 41.5% of non-elderly patients (P<0.001). Amongst elderly patients, the only independent predictor of good outcome was initial NIHSS score (adj. OR 0.882, 95% CI 0.821-0.948); good outcomes were achieved in 32.1% of those with NIHSS score < 10, 16.8% with NIHSS score 11-20, and only 5.9% with NIHSS score > 20. Conclusions: Patients > 80 years account for over one-fifth of those treated with ERT in this large registry and had worse outcomes compared with those < 80 years despite similar initial severity, time to treatment, and procedural results. Other factors such as increased baseline disability, more rapid time to completed infarction, and reduced neural plasticity may be contributing to these findings.

Purpose: Hemorrhagic transformation (HT) is a common and potentially devastating complication of ischemic stroke, however its prevalence, predictors, and outcome remain unclear. Early anticoagulation is thought to be a risk factor for HT which raises the clinical question when to (re)start anticoagulation in ischemic stroke patients who have a compelling indication, such as atrial fibrillation. We conducted a prospective cohort study to address this question and to identify association of hemorrhagic transformation with outcome measures in patients with atrial fibrillation in the setting of acute ischemic stroke. Materials and Methods: We performed a prospective study which enrolled consecutive patients admitted with acute ischemic stroke presenting to a single center over a three-year period. As part of the observational study, baseline clinical data and stroke characteristics as well as 3 month functional outcome were collected. For this sub-study, we restricted the analysis to subjects diagnosed with atrial fibrillation. CT and MRI scans were reviewed by experienced readers, blinded to clinical data, to assess for hemorrhagic transformation (using ECASS 2 criteria), microbleeds and infarct volumes in both admission and follow-up scans. Clinical and outcome data were analyzed for association with hemorrhagic transformation. Results: Of 94 patients, 63 had a history of atrial fibrillation (67.0%) and 31 had newly discovered atrial fibrillation (33.0%). We identified HT in 3 of 94 baseline scans (3.2%) and 22 of 48 follow-up scans (45.8%) obtained a median of 3 days post-stroke. In-hospital initiation of either anti-platelet (n = 36; OR 0.34 [95% CI 0.10-1.16], p-value = 0.09) or anticoagulation with unfractionated intravenous heparin or low molecular weight heparin (n = 72; OR 0.25 [95% CI 0.06-1.15], p-value = 0.08) was not associated with HT. Initial NIH Stroke Scale (NIHSS) score (median 13.0 [IQR 15.0] vs. 7.0 [IQR 10.0], p-value = 0.029) and baseline infarct volume (median 17 [IQR 42.03] vs. 5 [IQR 10.95], p-value = 0.011) were significantly higher in patients with HT compared to those without. Hemorrhagic transformation was associated with a significantly higher 48-hour median NIHSS score (20 [IQR 3.0] vs. 2 [IQR 3.25], p-value = 0.007) and larger final infarct volume (81.40 [IQR 82.75] vs. 9.95 [IQR 19.73], p-value < 0.001). Finally, we found a trend towards poorer 3-month modified Rankin Scale scores in subjects with HT (OR 11.25 [95% CI 0.97-130.22], p-value = 0.05). Conclusion: In patients with atrial fibrillation, initial NIHSS score and baseline infarct volume are associated with hemorrhagic transformation in acute ischemic stroke. Early initiation of antithrombotic therapy was not associated with hemorrhagic transformation. Patients with hemorrhagic transformation were found to have a poorer short and long term outcome and larger final infarct volumes.

Background: Non-occlusive thrombus in an intracranial artery in acute ischemic stroke is an uncommon occurrence. We compared the clinical course and outcome of intracranial subocclusive to occlusive thrombi. Methods: We conducted a review of patients who presented with acute ischemic stroke and received CT angiogram at a single comprehensive stroke center from January 2018 to December 2019. Patients with intracranial subocclusive thrombus were compared to a control group with complete occlusion matched for occlusion location. Subocclusive thrombus was reviewed by two raters on CT angiography, disagreement resolved by consensus. Patient and stroke characteristics and the clinical course were analyzed. Neurological deterioration was defined as an increase in NIH Stroke Scale (NIHSS) score > 4 compared from baseline to 48 hours. Good outcome at discharge was defined as modified Rankin Score of ≤2. Results: Among 1151 acute ischemic strokes, there were 896 patients with CT angiograms. Sixteen out of 896 (1.8%) patients had intracranial subocclusive thrombus. Thirty-two with comparable intracranial occlusions were identified. In the subocclusive group, 3 of 16 (19%) of received acute endovascular intervention, compared to 13 of 32 (41%) in the occluded group. Sex, median age or time from last known well to hospital arrival did not differ between the two groups. The subocclusive thrombus group had less severe strokes, with median NIHSS score at arrival 3 compared to 8.5 in the occlusion group (p<0.01) and median NIHSS at discharge 1 compared to 5.5 in the occlusive group (p<0.01). Frequency of neurological deterioration in hospital did not differ between the subocclusive and occluded groups at 48 hours (15% vs 15% p=1.00). The subocclusive group was associated with a good outcome at discharge, OR 0.5.71, 95% confidence interval 1.41-23.1. Conclusion: Intracranial subocclusive thrombus in acute ischemic stroke has a more mild presentation compared to complete intracranial occlusion without a high rate of neurological deterioration.

Background: Large vessel occlusions with a high clot burden are less likely to improve with the FDA-approved IV strategy. Endovascular therapy within the first 3 h of stroke symptom onset provides an effective alternative treatment in patients with large vessel occlusion. It is not clear if combination of IV thrombolysis and endovascular approach is superior to endovascular treatment alone. Methods: We retrospectively reviewed all cases of acute ischemic stroke with large vessel occlusion treated within the first 3 h stroke onset during the 2005-2010 period. First group received endovascular therapy within the first 3 h of stroke onset. Second group consisted of patients who received IV thrombolysis within the first 3 h followed by endovascular therapy. We compared the following outcomes: revascularization rates, NIHSS score at discharge, mRS at discharge and 3months, symptomatic hemorrhage rates and mortality. Results: Among 104 patients identified, 42 received combined therapy, and 62 received endovascular therapy only. The two groups had similar demographic (age and sex distribution) and vascular risk factors distribution, as well as NIHSS score on admission (14.8±4.7 and 16.0±5.3; p=0.23). We found no difference in TIMI recanalization rates (Thrombolysis in Myocardial Infarction scale score of 2 or 3) following combined or endovascular therapy alone (83.3% and 79.0%; p=0.59). A preferred outcome, defined as a mRS of 2 or less at 90 days also did not differ between the combined therapy group and the endovascular only group (37.5% and 34.5%; p=0.76). There was no difference in mortality rate (22.5% and 31.0%; p=0.36) and the rate of symptomatic intracranial hemorrhage (9.5% and 8.1%; p=0.73). There was a significant difference in mean time from symptom onset to endovascular treatment between the combined group (227±88 min) and endovascular only group (125±40 min; p<0.0001).Patients with good TIMI recanalization rate of 2 or 3 showed a trend of having a better mRS at 90 days in both bridging (16.67% vs. 41.18%, p-value: 0.3813) and endovascular groups (25% vs. 34.78%, p-value: 0.7326).When analyzing the correlation of mRS at 90 days with the site of occlusion, patients in the bridging group showed a trend of a better outcome when the site of occlusion was ICA (33.3% vs 30%) and MCA (66.67% vs. 27.59%) and worse outcome when the site of occlusion was in the posterior circulation (26.32% vs. 50%), however, these results were not statistically significant (p-values: 0.1735& 0.5366). Conclusion: Combining IV thrombolysis and endovascular therapy achieves similar rates of clinical outcomes, revascularization rates, complications and mortality rates, when compared with endovascular treatment alone. The combined therapy, however, significantly delays initiation of endovascular treatment. A randomized prospective trial comparing both treatment strategies in acute ischemic stroke is warranted

Background: Guidelines do not recommend reperfusion therapy in acute ischemic stroke patients with mild symptoms considering low gain compared to the risk. However, some patients with mild first symptoms experience neurological deterioration (ND) after hospitalization. We aimed to analyze clinical features and outcomes of patient who received reperfusion therapy after ND occurred. Methods: We enrolled patients who were admitted within 7 days after acute ischemic stroke or TIA between January 2012 and July 2018 from a multicenter stroke registry database in Korea (CRCS-K). Patients who 1) admitted via emergency room, and 2) received reperfusion therapy including intravenous tissue plasminogen activator and/or endovascular treatment were included. Clinical features and outcomes such as modified Rankin Scale (mRS) score distribution at 3 months after stroke were compared between patients received reperfusion therapy after ND and those without ND before the treatment. Results: Among 51325 patients, 6577 (12.8%) received reperfusion therapy were identified. Reperfusion therapy was performed after ND in 136 patients (2.1%). Mean time of onset to needle is 342.1 and 167.2, and onset to perfusion is 1351.6 and 422.0 in patients treated after ND, and those without, respectively. TIA history was more frequent and atrial fibrillation history was less frequent in patients treated after ND. Initial median (IQR) National Institute of Health Stroke Scale (NIHSS) score was 8 (5 - 12), 10 (6 - 16) in patients treated after ND, and those without, respectively. Large artery atherosclerosis was more frequent in patients treated after ND (42.9 % vs. 26.7%). There was higher rate of good outcome at 90 days in patients treated after ND (84 [61.8%]) compared with those without ND before treatment (3359 [52.2%]; OR, 1.38 [95% CI, 1.02-1.87]). In multivariable analysis, good outcome at 90 days in patients treated after ND lacked statistical significance (OR, 1.06 [95% CI, 0.71-1.62]). There is no significant statistical difference of death at 90 days (13.2% vs. 10.4%, p = 0.364). Conclusion: Reperfusion therapy could apply patients with mild first symptoms experience ND after hospitalization and expect similar prognosis compared to those without ND before the treatment.

Background and Purpose: More than half of patients with acute ischemic stroke have minor neurological deficits; however, the frequency and outcomes of reperfusion therapy in regular practice has not been well-delineated. Methods: Analysis of US National Inpatient Sample of hospitalizations with acute ischemic stroke and mild deficits (National Institutes of Health Stroke Scale [NIHSS] score 0–5) from October 1, 2016, to December 31, 2017. Patient- and hospital-level characteristics associated with use and outcome of reperfusion therapies were analyzed. Primary outcomes included excellent discharge disposition (discharge to home without assistance); poor discharge disposition (discharge to facility or death); in-hospital mortality; and radiological intracranial hemorrhage. Results: Among 179 710 acute ischemic stroke admissions with recorded NIHSS during the 15-month study period, 103 765 (57.7%) had mild strokes (47.3% women; median age, 69 [interquartile range, 59–79] years; median NIHSS score of 2 [interquartile range, 1–4]). Considering reperfusion therapies among strokes with documented NIHSS, mild deficit hospitalizations accounted for 40.0% of IVT and 10.7% of mechanical thrombectomy procedures. Characteristics associated with IVT and with mechanical thrombectomy utilization were younger age, absence of diabetes, higher NIHSS score, larger/teaching hospital status, and Western US region. Excellent discharge outcome occurred in 48.2% of all mild strokes, and in multivariable analysis, was associated with younger age, male sex, White race, lower NIHSS score, absence of diabetes, heart failure, and kidney disease, and IVT use. IVT was associated with increased likelihood of excellent outcome (odds ratio, 1.90 [95% CI, 1.71–2.13], P <0.001) despite an increased risk of intracranial hemorrhage (odds ratio, 1.41 [95% CI, 1.09–1.83], P <0.001). Conclusions: In national US practice, more than one-half of acute ischemic stroke hospitalizations had mild deficits, accounting for 4 of every 10 IVT and 1 of every 10 mechanical thrombectomy treatments, and IVT use was associated with increased discharge to home despite increased intracranial hemorrhage.

Background and purpose Previous studies have reported that early hospital arrival improves clinical outcomes in patients with acute ischemic stroke; however, whether early arrival is associated with favorable outcomes regardless of reperfusion therapy and the type of stroke onset time is unclear. Thus, we investigated the impact of onset-to-door time on outcomes and evaluated the predictors of pre-hospital delay after ischemic stroke. Methods Consecutive acute ischemic stroke patients who arrived at the hospital within five days of onset from September 2019 to May 2020 were selected from the prospective stroke registries of Seoul National University Hospital and Chung-Ang University Hospital of Seoul, Korea. Patients were divided into early (onset-to-door time, ≤4.5 h) and late (>4.5 h) arrivers. Multivariate analyses were performed to assess the effect of early arrival on clinical outcomes and predictors of late arrival. Results Among the 539 patients, 28.4% arrived early and 71.6% arrived late. Early hospital arrival was significantly associated with favorable outcomes (three-month modified Rankin Scale [mRS]: 0−2, adjusted odds ratio [aOR]: 2.03, 95% confidence interval: [CI] 1.04–3.96) regardless of various confounders, including receiving reperfusion therapy and type of stroke onset time. Furthermore, a lower initial National Institute of Health Stroke Scale (NIHSS) score (aOR: 0.94, 95% CI: 0.90–0.97), greater pre-stroke mRS score (aOR: 1.58, 95% CI: 1.18–2.13), female sex (aOR: 1.71, 95% CI: 1.14–2.58), unclear onset time, and ≤6 years of schooling (aOR: 1.76, 95% CI: 1.03–3.00 compared to >12 years of schooling) were independent predictors of late arrival. Conclusions Thus, the onset-to-door time of≤4.5 h is crucial for better clinical outcome, and lower NIHSS score, greater pre-stroke mRS score, female sex, unclear onset times, and ≤6 years of schooling were independent predictors of late arrival. Therefore, educating about the importance of early hospital arrival after acute ischemic stroke should be emphasized. More strategic efforts are needed to reduce the prehospital delay by understanding the predictors of late arrival.

Background: Tools to predict outcome after endovascular reperfusion therapy (ERT) for acute ischemic stroke (AIS) have previously included only pre-treatment variables. We sought to derive and validate an outcome prediction score based on readily available pre-treatment and treatment factors. Methods: The derivation cohort consisted of 516 patients with anterior circulation AIS from 9 centers from September 2009-July 2011. The validation cohort consisted of 110 patients with anterior circulation AIS from the Penumbra Pivotal Trial. Multivariable logistic regression identified predictors of good outcome, defined as a modified Rankin Score (mRS) of < 2, in the derivation sample; model beta coefficients were used to assign point scores. Discrimination was tested using C-statistics. We then validated the score in the Penumbra cohort and performed calibration (predicted versus observed good outcome) in both cohorts. Results: Good outcome at 3 months was noted in 189 (36.8%) patients in the derivation cohort. The independent predictors of good outcome were A ge (2 pts: <60; 1 pt: 60-79; 0 pts: >79), N IHSS score (4 pts: 0-10; 2 pts: 11-20; 0 pts: > 20), L ocation of clot (2 pts: M2; 1 pt: M1; 0 pts: ICA), R ecanalization (5 pts: TICI 2 or 3), and S ymptomatic hemorrhage (2 pts: none, HT1-2, or PH1; 0 pts: PH2). The outcome (SNARL) score demonstrated good discrimination in the derivation cohort (C-statistic 0.78, 95% CI 0.72-0.78) and validation cohort (C-statistic 0.74, 95% CI 0.64-0.84). There was excellent calibration in each cohort (Figure). Conclusions: The SNARL score is a validated tool to determine the probability of functional recovery among AIS treated with endovascular reperfusion strategies. Unlike previous scores that did not include treatment factors such as successful recanalization or hemorrhagic complications, our score can be applied to patients after treatment and may provide guidance to physicians, patients, and families about expected functional outcome.

Background: It is unknown if intraprocedural blood pressure (BP) influences clinical outcomes and what BP parameter best predicts outcomes in acute ischemic stroke (AIS) patients who undergo intra-arterial therapy (IAT) for emergent large vessel occlusion. Methods: We retrospectively reviewed 147 patients who underwent IAT for anterior circulation AIS from January 2008 to December 2012 at our institution. Baseline demographics, stroke treatment variables, and detailed intraprocedural hemodynamic variables were collected. Results: The entire cohort consisted of 81 (55%) females with a mean age of 66.9 ± 15.6 years and a median National Institutes of Health Stroke Scale (NIHSS) score of 16 (IQR 11-21). Thirty-six (24.5%) patients died during hospitalization, 25 (17%) achieved a 30-day modified Rankin Scale score of 0-2, and 24 (16.3%) suffered symptomatic parenchymal hematoma type 1/2 hemorrhage. Patients who achieved a good outcome had a significantly lower admission NIHSS score, a higher baseline CT ASPECTS score, and a lower rate of ICA terminus occlusions. Successful recanalization was more frequent in the good-outcome group, while symptomatic hemorrhages occurred only in poor-outcome patients. The first systolic BP (SBP; 146.5 ± 0.2 vs. 157.7 ± 25.6 mm Hg, p = 0.042), first mean arterial pressure (MAP; 98.1 ± 20.8 vs. 109.7 ± 20.3 mm Hg, p = 0.024), maximum SBP (164.6 ± 27.6 vs. 180.9 ± 18.3 mm Hg, p = 0.0003), and maximum MAP (125.5 ± 18.6 vs. 138.5 ± 24.6 mm Hg, p = 0.0309) were all significantly lower in patients who achieved good outcomes. A lower maximum intraprocedural SBP was an independent predictor of good outcome (adjusted OR 0.929, 95% CI 0.886-0.963, p = 0.0005). Initial NIHSS score was the only other independent predictor of a good outcome. Conclusion: Lower intraprocedural SBP was associated with good outcome in patients undergoing IAT for AIS, and maximum SBP was an independent predictor of good outcome. SBP may be the optimal hemodynamic variable to monitor intraprocedurally during IAT and may predict outcome.

Background: Stroke is a serious public health issue and third leading cause of death worldwide. Hypoalbuminemia is commonly found factor in patients of stroke and is also associated with severe disease as well as pro inflammatory patterns of serum protein electrophoresis. Therefore, further research for understanding the role of Hypoalbuminemia in stroke is important to devise strategies for better management of stroke. Aim : To determine the frequency of hypoalbuminemia in acute ischemic stroke patients based on stroke severity. Methods: This descriptive cross- sectional study was conducted in Shifa International hospital stroke unit for 6 months from May 15, 2018 till Nov 15, 2018. Data was collected from 100 patients using purposive sampling. After taking consent from patient or attendant, the demographic data was collected on a structured proforma. Baseline serum albumin and stroke severity using the NIHSS score was also assessed. All data was entered and analysed using SPSS 21. After descriptive analysis, post stratified Chi Square test was applied for gender and age categories. Results: The mean age of patients was 63.60 ± 11.87 years with 57(57%) male and 43(43%) female cases. The mean serum albumin level was 4.03 ± 0.94 with minimum and maximum values as 1.50 and 5.5. Among cases with minor, moderately severe and with severe stroke, 6(37.5%) cases, 18(25.7%) cases and 6(42.9%) cases had Hypoalbuminemia. The frequency of hypoalbuminemia was statistically same with respect to severity of stroke, p-value > 0.05. Conclusion: This study concludes that the frequency of hypoalbuminemia in acute ischemic stroke patients was diagnosed in almost one third cases, however, no statistical association could be found. Hence, screening for hypoalbuminemia should be done for better management of stroke patients. Keywords: Storke, NIHSS score, serum albumin, hypoalbuminemia, mortality

Purpose: Mechanical thrombectomy has been demonstrated to provide benefits in the treatment of acute ischemic stroke (AIS). But whether to treat AIS patients with a large infarct core remains controversial. Although it is a common practice that patients with large infarct core are not offered endovascular treatment, previous data have consistently shown a proportion of these patients may benefit from IA intervention. The purpose of this study is to identify predictors of good outcomes in an AIS cohort with a large infarct volume previously treated with mechanical thrombectomy. Hypothesis: We hypothesize that among AIS patients with a large infarct volume, younger patients (≤66 years) who present with lower NIHSS scores will show good functional outcomes (mRS 0-2) at 90 days if treated with mechanical thrombectomy. Methods: Univariable and multivariable analyses were preformed to identify factors that predict good functional outcomes in AIS patients with ASPECTS 0-5 who were treated with the Penumbra System. Five previous prospective, multicenter trials (PIVOTAL, PICS, RetroSTART, START, SEPARATOR 3D) were included in this study. Patients who presented with symptoms of AIS were analyzed for association between presenting demographics and modified Rankin scale (mRS) score at 90 days in univariate and multivariate analyses. Results: Data for 614 patients with a median age of 69 years and an NIHSS score of 18 met study criteria. Of these, the 90-day mRS 0-2 rate and mortality were, respectively, 40.23% and 25.41%. Among those with ASPECTS 0-5 (N=93), 17.20% had good functional outcome. An age of ≤66 years was significantly associated with good outcome (p<0.0001) among those with ASPECTS 0-5. Within this age group who had ASPECTS 0-5, a baseline NIHSS score of ≤ 20 (p= 0.0088) with a target vessel location at the MCA (p=0.0210) were also strong predictors of good outcome if treated by mechanical thrombectomy. Conclusion: These data demonstrate that age ≤66 years, baseline NIHSS score of ≤ 20 with a target vessel location in the MCA are important predictors of good outcomes in an AIS cohort with a large infarct core who are eligible for mechanical thrombectomy.
