Baseline Factors

<b><i>Background:</i></b> The aim of the study was to investigate the baseline characters that influence 3-month clinical outcomes in patients with acute ischemic stroke (AIS) after thrombolytic therapy. <b><i>Methods:</i></b> We consecutively enrolled 241 AIS patients who are treated with thrombolytic therapy with recombinant tissue plasminogen activator. Baseline characters were measured on admission including the National Institutes of Health Stroke Scale (NIHSS), Trial of Org 10172 in Acute Stroke Treatment (TOAST), risk factors, platelet indices, and lipid parameters. The subjects were divided into good or poor functional outcomes based on modified Rankin Scale at 3 months. The multivariate logistic regression was performed to explore the association between baseline factors and outcomes. Pearson correlation was used to investigate whether linear associations existed between platelet indices in different outcomes. <b><i>Results:</i></b> Multivariate logistic regression analysis showed that the NIHSS, TOAST classification, diabetes, mean platelet volume (MPV) are important factors for predicting clinical outcomes after 3 months in AIS patients. We found a correlation between elevated MPV and worse outcome at 3 months, particularly in large-artery atherosclerosis stroke patients. MPV and platelet count are negative correlated (<i>r</i> = −0.375, <i>p</i> = 0.000). MPV and platelet-to-lymphocyte ratio (PLR) (<i>r</i> = 0.83, <i>p</i> = 0.000), MPV and platelet distribution width (PDW) (<i>r</i> = 0.820, <i>p</i> = 0.000) both have highly positive linear correlations in patients with good outcome. <b><i>Conclusions:</i></b> Overall, lower NIHSS and MPV levels on admission were predictors of good functional outcomes in patients with AIS after undergoing thrombolytic therapy. The correlations between MPV, PDW, and PLR may be helpful to evaluate prognosis in stroke patients and deserve further exploration.

ABSTRACT Objective We aimed to develop a model to predict unfavorable outcome in patients with acute ischemic stroke treated with intravenous thrombolytic therapy (IVT), based on simple variables present on admission. Methods Retrospective analysis of acute ischemic stroke patients treated with IVT in a hospital in Rio de Janeiro. Clinical and radiographic variables were selected for analysis. Multivariate logistic regression was used to develop a predictive model. Results We analyzed a total of 82 patients. Median National Institutes of Health Stroke Scale (NIHSS) on admission was 9 (3–22), 40.2% presented with a hyperdense artery sign (HAS), 62% had identifiable early parenchymal changes and 61.6% experienced a favorable outcome. An NIHSS score of > 12 on arrival, age > 70 and the presence of HAS were associated with the outcome, even after correction in a logistic regression model. Conclusion An NIHSS > 12 on arrival, presence of HAS and age > 70 years were predictors of unfavorable outcome at three months in patients with acute ischemic stroke treated with IVT.

Cognitive decline is a significant complication that affects most stroke survivors. Early detection of cognitive decline in ischemic stroke patients and identification of risk factors improves their clinical outcomes. This study aimed to determine the characteristics of cognitive status in the sub-acute phase of ischemic stroke. A cross-sectional study was conducted on 89 sub-acute ischemic stroke patients in three hospitals in West Nusa Tenggara recruited consecutively from August 2019 to April 2020. The data collected were demographic and clinical characteristics, cognitive status, and functional outcome. The association between clinical and demographic characteristics and cognitive decline was analyzed using logistic regression. In addition, the relationship between cognitive status and functional outcomes of these patients was examined using the chi-square test. This study revealed that the prevalence of cognitive decline in these subjects was 71.9%. Multiple logistic regression showed that age was the only characteristic associated with cognitive decline in the subjects (OR = 5.12,95% CI = 1.08-24.28). Furthermore, the frequency of cognitive decline in these subjects was significantly associated with functional outcomes (p-value =0.014). Thus, there was a high prevalence of cognitive decline in sub-acute ischemic stroke patients associated with increasing age and poor functional outcomes.

Abstract Background Insulin resistance is associated with the occurrence of stroke and atherosclerotic disease. However, the relationship between insulin resistance and the prognosis of acute ischemic stroke in nondiabetic patients is unclear. We hypothesized that insulin resistance may affect short-term functional recovery after acute ischemic stroke in nondiabetic patients. Methods Between May 2014 and December 2016, 1377 consecutive patients with acute ischemic stroke were enrolled from a prospectively maintained stroke registry. After excluding patients with transient ischemic attacks (TIA), pre-stroke disabilities, diabetes mellitus, and patients with incomplete evaluations, 517 patients were included in the study. The homeostasis model assessment of insulin resistance (HOMA-IR) score was used to evaluate the degree of insulin resistance. The factors associated with poor functional outcomes were analyzed using multivariate logistic regression. Results The patients with the highest quartile of log HOMA-IR index scores were younger and had higher fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein, and HbA1c levels. Multivariate logistic regression analysis revealed that log HOMA-IR scores were independently associated with poor prognosis after adjusting for age and sex and p < 0.1 in univariate analysis. Conclusion Insulin resistance measured by the HOMA-IR index was associated with the poor functional outcome of non-diabetic stroke patients. This evidence supports treating insulin resistance in acute ischemic stroke patients with blood glucose levels within the normal range.

Statin Use

Background: Statin therapy has been shown to be effective in the prevention of ischemic stroke. In addition, recent studies have suggested that prior statin therapy could lower the initial stroke severity and improve stroke functional outcomes in the event of stroke. It was speculated that prestroke statin use may enhance collateral circulation and result in favorable functional outcomes. Objective: The aim of the study was to investigate the association of prestroke statin use with leptomeningeal collaterals and to determine the association of prestroke statin use with stroke severity and functional outcome in acute ischemic stroke patients. Methods: We prospectively and consecutively enrolled 239 acute ischemic stroke patients with acute infarction due to occlusion of the middle cerebral artery within 24 h in the neurology department of West China Hospital from May 2011 to April 2017. Computed tomographic angiography (CTA) imaging was performed for all patients to detect middle cerebral artery thrombus; regional leptomeningeal collateral score (rLMCS) was used to assess the degree of collateral circulation; the National Institutes of Health Stroke Scale (NIHSS) was used to measure stroke severity at admission; the modified Rankin scale (mRS) was used to measure outcome at 90 days; and premorbid medications were recorded. Univariate and multivariate analyses were performed. Results: Overall, 239 patients met the inclusion criteria. Fifty-four patients used statins, and 185 did not use statins before stroke onset. Prestroke statin use was independently associated with good collateral circulation (rLMCS > 10) (odds ratio [OR], 4.786; 95% confidence interval [CI], 1.195–19.171; P = 0.027). Prestroke statin use was not independently associated with lower stroke severity (NIHSS score≤14) (OR, 1.955; 95% CI, 0.657–5.816; p = 0.228), but prestroke statin use was independently associated with favorable outcome (mRS score≤2) (OR, 3.868; 95% CI, 1.325–11.289; P = 0.013). Conclusions: Our findings suggest that prestroke statin use was associated with good leptomeningeal collaterals and clinical outcomes in acute ischemic stroke (AIS) patients presenting with occlusion of the middle cerebral artery. However, clinical studies should be conducted to verify this claim.

Background: Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. Methods: Over a 4.5-year period (starting November 2007), all consecutive AIS patients from 15 hospitals in Schleswig-Holstein, Germany, were prospectively evaluated. The primary outcomes were stroke-related pneumonia during hospitalization, mortality, and disability measured on the modified Rankin Scale ≥2-5, in which 2 indicates an independence/slight disability to 5 severe disability. Results: Of 12,276 patients (mean age 73 ± 13; 49% women), 9,164 patients (74%) underwent dysphagia screening; of these patients, 55, 39, 4.7, and 1.5% of patients had been screened for dysphagia within 3, 3 to <24, 24 to ≤72, and >72 h following admission. Patients who underwent dysphagia screening were likely to be older, more affected on the National Institutes of Health Stroke Scale score, and to have higher rates of neurological symptoms and risk factors than patients who were not screened. A total of 3,083 patients (25.1%; 95% CI 24.4-25.8) had dysphagia. The frequency of dysphagia was higher in patients who had undergone dysphagia screening than in those who had not (30 vs. 11.1%; p < 0.001). During hospitalization (mean 9 days), 1,271 patients (10.2%; 95% CI 9.7-10.8) suffered from stroke-related pneumonia. Patients with dysphagia had a higher rate of pneumonia than those without dysphagia (29.7 vs. 3.7%; p < 0.001). Logistic regression revealed that dysphagia was associated with increased risk of stroke-related pneumonia (OR 3.4; 95% CI 2.8-4.2; p < 0.001), case fatality during hospitalization (OR 2.8; 95% CI 2.1-3.7; p < 0.001) and disability at discharge (OR 2.0; 95% CI 1.6-2.3; p < 0.001). EDS within 24 h of admission appeared to be associated with decreased risk of stroke-related pneumonia (OR 0.68; 95% CI 0.52-0.89; p = 0.006) and disability at discharge (OR 0.60; 95% CI 0.46-0.77; p < 0.001). Furthermore, dysphagia was independently correlated with an increase in mortality (OR 3.2; 95% CI 2.4-4.2; p < 0.001) and disability (OR 2.3; 95% CI 1.8-3.0; p < 0.001) at 3 months after stroke. The rate of 3-month disability was lower in patients who had received EDS (52 vs. 40.7%; p = 0.003), albeit an association in the logistic regression was not found (OR 0.78; 95% CI 0.51-1.2; p = 0.2). Conclusions: Dysphagia exposes stroke patients to a higher risk of pneumonia, disability, and death, whereas an EDS seems to be associated with reduced risk of stroke-related pneumonia and disability.

Procedural Time

Background: Recent single center studies have suggested that “procedural time” independent of “time to procedure” can affect outcomes of acute ischemic stroke patients undergoing endovascular treatment (ET). We performed a pooled analysis from three ET trials to determine the effect of procedural time on angiographic and clinical outcomes. Objective: To determine the relationship between procedural time and clinical outcomes among acute ischemic stroke patients undergoing successful recanalization with ET. Methods: We analyzed data from SWIFT, STAR and SWIFT PRIME trials. Baseline demographic and clinical characteristics, NIHSS score on admission, intracranial hemorrhage rates and mRS at 3 months post procedure were analyzed. TICI scale was used to grade post procedure angiographic recanalization. Procedural time was defined by the time interval between groin puncture and recanalization. We estimated the procedural time after which favorable clinical outcome was unlikely even after recanalization (futile) after age and NIHSS score adjustment. Results: We analyzed 301 patients who underwent ET and had near complete or complete recanalization (TICI 2b or 3). The procedural time (±SD) was significantly shorter in patients who achieved a favorable outcome (mRS 0-2) compared with those who did not achieve favorable outcome (44±25 vs 51±33 minutes, p=0.04). Table 1. In the multivariate analysis (including all baseline characteristics with a p value <0.05 as independent variables), shorter procedural time was a significant predictor of lower odds of unfavorable outcome (OR 0.49, 95% CI 0.28, 0.85, p=0.012). The rates of favorable outcomes were significantly higher when the procedural time was <60 minutes compared with ≥60 minutes (62% vs 45%, p=0.020). Conclusion: Procedural time in patients undergoing mechanical thrombectomy for acute ischemic stroke is an important determinant of favorable outcomes in those with near complete or complete recanalization.

Introduction: Impaired hydration measured by elevated blood urea nitrogen (BUN) to creatinine ratio has been associated with worsened outcome after acute ischemic stroke. Whether hydration status is relevant for patients with acute ischemic stroke treated with mechanical thrombectomy remains unknown. Materials and Methods: We conducted a retrospective review of consecutive acute ischemic stroke patients who underwent endovascular procedures for anterior circulation large artery occlusion at Johns Hopkins Comprehensive Stroke Centers between 2012 and 2017. A volume contracted state (VCS), was determined based on surrogate lab markers and defined as blood urea nitrogen (BUN) to creatinine ratio greater than 15. Endpoints were achievement of successful revascularization (TICI 2b or 3), early re-occlusion, and short term clinical outcomes including development of early neurological worsening and functional outcome at 3 months. Results: Of the 158 patients who underwent an endovascular procedure, 102 patients had a final diagnosis of anterior circulation large vessel occlusion and met the inclusion criteria for analysis. Volume contracted state was present in 62/102 (61%) of patients. Successful revascularization was achieved in 75/102 (74%) of the cohort. There was no relationship between VCS and successful revascularization, but there was a 1.13 increased adjusted odds (95% CI 1.01, 1.27) of re-occlusion within 24 hours for every point higher BUN/creatinine ratio in the subset of patients who underwent radiological testing for pre-procedure planning (n=57). There was no relationship between VCS and clinical outcomes including early neurological worsening and 3 month outcome. Conclusions: Patients with VCS and large vessel anterior circulation stroke may have a higher odds of early re-occlusion after mechanical thrombectomy than their non-VCS counterparts, but no differences in successful revascularization nor clinical outcomes were present in this cohort. These results may suggest an opportunity for the exploration of pre-procedure hydration to improve outcomes.
