Introduction: Pre-stroke dementia is significantly associated with poor stroke outcome. Cholinesterase inhibitors (ChEIs) might reduce the risk of stroke in patients with dementia. However, the association between pre-stroke ChEI treatment and stroke outcome remains unresolved. Therefore, we aimed to determine this association in patients with acute ischemic stroke and pre-stroke dementia. Methods: We enrolled 805 patients with pre-stroke dementia among 13,167 with ischemic stroke within 7 days of onset who were registered in the Fukuoka Stroke Registry between June 2007 and May 2019 and were independent in basic activities of daily living (ADLs) before admission. Primary and secondary study outcomes were poor functional outcome (modified Rankin Scale [mRS] score: 3–6) at 3 months after stroke onset and neurological deterioration (≥2-point increase in the NIH Stroke Scale [NIHSS] during hospitalization), respectively. Logistic regression analysis was used to evaluate associations between pre-stroke ChEI treatment and study outcomes. To improve covariate imbalance, we further conducted a propensity score (PS)-matched cohort study. Results: Among the participants, 212 (26.3%) had pre-stroke ChEI treatment. Treatment was negatively associated with poor functional outcome (odds ratio: 0.68 [95% confidence interval: 0.46–0.99]) and neurological deterioration (0.52 [0.31–0.88]) after adjusting for potential confounding factors. In the PS-matched cohort study, the same trends were observed between pre-stroke ChEI treatment and poor functional outcome (0.61 [0.40–0.92]) and between the treatment and neurological deterioration (0.47 [0.25–0.86]). Conclusions: Our findings suggest that pre-stroke ChEI treatment is associated with reduced risks for poor functional outcome and neurological deterioration after acute ischemic stroke in patients with pre-stroke dementia who are independent in basic ADLs before the onset of stroke.

Background: Dementia and stroke are major causes of disability in the elderly. However, the association between pre-stroke dementia and functional outcome after stoke remains unresolved. We aimed to determine this association in patients with acute ischemic stroke. Methods: Among patients registered in the Fukuoka Stroke Registry from June 2007 to May 2015, 4,237 patients with ischemic stroke within 24 h of onset, who were functionally independent before the onset, were enrolled in this study. Pre-stroke dementia was defined as any type of dementia that was present prior to the index stroke. Primary and secondary study outcomes were poor functional outcome (modified Rankin Scale 3-6) at 3 months after the stroke onset and neurological deterioration (≥2-point increases on the National Institutes of Health Stroke Scale score during hospitalization), respectively. For propensity score (PS)-matched cohort study to control confounding variables for pre-stroke dementia, 318 pairs of patients with and without pre-stroke dementia were also selected on the basis of 1:1 matching. Multivariable logistic regression models and conditional logistic regression analysis were used to quantify associations between pre-stroke dementia and study outcomes. Results: Of all 4,237 participants, 347 (8.2%) had pre-stroke dementia. The frequencies of neurological deterioration and poor functional outcome were significantly higher in patients with pre-stroke dementia than in those without pre-stroke dementia (neurological deterioration, 16.1 vs. 7.1%, p < 0.01; poor functional outcome, 63.7 vs. 27.1%, p < 0.01). Multivariable analysis showed that pre-stroke dementia was significantly associated with neurological deterioration (OR 1.67; 95% CI 1.14-2.41; p < 0.01) and poor functional outcome (OR 2.91; 95% CI 2.17-3.91; p < 0.01). In the PS-matched cohort study, the same trends were observed between the pre-stroke dementia and neurological deterioration (OR 2.60; 95% CI 1.17-5.78; p < 0.01) and between the dementia and poor functional outcome (OR 3.62; 95% CI 1.89-6.95; p < 0.01). Conclusions: Pre-stroke dementia was significantly associated with higher risks for poor functional outcome at 3 months after stroke onset as well as for neurological deterioration during hospitalization in patients with acute ischemic stroke.

Background: Lipoprotein A (Lp(a)) is a risk factor for vascular disease; however, few studies have examined the relationship between serum levels of Lp(a) and patient outcomes in acute ischemic stroke (AIS). In this study, we sought to assess whether AIS patients with elevated Lp(a) levels exhibit characteristic differences in stroke severity, in-hospital complications, and short-term outcomes as compared to patients with normal Lp(a) levels. Methods: From our prospective stroke registry, patients consecutively admitted and diagnosed with AIS 07/2008-10/2013 were included if Lp(a) levels were measured during admission. Regressions, adjusting for key covariates, analyzed outcomes in patients with elevated (+) and severely elevated (++) Lp(a) with respect to normal (-) Lp(a). The primary outcome was poor functional outcome (modified Rankin Scale > 2) on discharge. Results: Among the 1,453 patients in our stroke registry, 159 patients met our inclusion criteria; 24 patients (15.1%) were in the +Lp(a) group and 37 patients (23.3%) in the ++Lp(a) group. After adjustment for total cholesterol, LDL, HDL, and triglycerides, patients with ++Lp(a) were more than twice as likely to experience poor functional outcome (OR=2.48, 95% CI 1.0781-5.7231, p=0.033) as those with -Lp(a). Adjusting for age, NIHSS baseline, history of diabetes, admission glucose level, and tPA administration, patients with ++Lp(a) were more than 2.5 times more likely to experience poor functional outcome (OR=2.59, 95% CI 1.0129-6.6282, p=0.047) as compared to those with -Lp(a). Conclusions: Lp(a) elevation predicts higher odds of poor functional outcomes for patients with AIS compared to patients with normal levels. Our findings support the utility of Lp(a) level as a clinically useful biomarker in the development of patient risk profiles.

Introduction: To date, few studies have assessed the influence of infection on neurological deterioration (ND) and other outcome measures in acute ischemic stroke. Methods: Patients admitted to our stroke center (07/08-12/10) were retrospectively assessed. Patients were excluded if they had an in-hospital stroke, unknown time of symptom onset, or delay from symptom onset to hospital arrival >48 hours. Positive blood or urine culture, or chest x-ray consistent with pneumonia were classified as infection and stratified according to whether the infection was diagnosed within the first 24 hours of admission or after 24 hours. ND was defined as an increase ≥2 points on the NIHSS score within a 24hr period. Poor functional outcome was defined as a mRS score of 3-6 on discharge. Results: Of the 334 patients included in this study, 78 had an infection (19 on admission). The majority of infections were found in the urinary tract (64%), while pneumonia (37%) and bacteremia (24%) were also common. Infection on admission was predictive of ND (Table 1; OR=2.79, 95% CI 1.18-6.64, p=0.0211) and poor functional outcome (OR=3.0, 95% CI 1.1-7.9, p=0.0182). Developing an infection during acute hospitalization was an even stronger predictor of ND (OR=11.9, 95% CI 5.8-24.5, p<0.0001) and poor functional outcome (OR=56.4, 95% CI 7.7-414, p<0.0001). After adjusting for age, NIHSS at baseline and glucose on admission, the development of an infection during acute hospitalization remained a significant predictor of ND (OR=8.9, 95% CI 4.2-18.6, p<0.0001) and poor functional outcome (OR=41.7, 95% CI 5.2-337.9, p=0.005) while an infection on admission was no longer predictive of ND (OR=1.5, 95%CI 0.59-3.99, p=0.3738) or poor functional outcome (OR=1.09, 95%CI 0.3-3.9, p=0.8984). Conclusion: Our data suggest that ischemic stroke patients who develop an infection during their acute hospitalization are at increased odds of experiencing ND and of being discharged with significant disability.

Abstract Background: Fibrinogen is involved in acute stroke. This study aimed to investigate the association between fibrinogen and prognosis in patients with acute ischemic stroke or transient ischemic attack (TIA). Methods: Using data from the CNSR-Ⅲ (Third China National Stroke Registry), this sub-study included 10 518 (69%) consecutive patients who had fibrinogen levels measured. The primary outcome was a poor functional outcome defined as modified Rankin Scale score of 3 to 6 within 90 days. The secondary outcomes were stroke recurrence, ischemic stroke recurrence, composite vascular events, and poor functional outcome during the 1-year follow-up and a new vascular event at 90 days. Multivariate logistic regression and Cox regression analyses were used to assess the associations between fibrinogen and prognosis of patients. Results: In total, 1446 (13.9%) patients had a poor functional outcome at 90 days. High fibrinogen levels were associated with poor functional outcome (adjusted odds ratio [OR], 1.35; 95% confidence interval [CI], 1.12-1.64) at 90 days after adjustment for confounding risk factors. High fibrinogen levels also independently predicted poor functional outcome during the 1-year follow-up. Stroke recurrence occurred in 657 (6.3%) patients at 90 days. High fibrinogen levels were associated with stroke recurrence, ischemic stroke recurrence, and composite vascular events in the crude model, but further adjustment eliminated these associations in the multivariate models. Conclusion: Our study showed that high fibrinogen level was independently associated with poor functional outcome but not with stroke recurrence in patients with acute ischemic stroke or TIA.

Introduction: With an aging population, an increased number of acute stroke patients with pre-stroke dementia is expected. Although both stroke and dementia are major cause of disability, the effect of pre-stroke dementia on functional outcome after stroke has been still on debate. Hypothesis: Pre-stroke dementia is associated with poor functional outcome after acute ischemic stroke. Methods: Of 9198 stroke patients registered in the Fukuoka Stroke Registry in Japan from June 2007 to May 2014, 3843 patients with first-ever ischemic stroke within 24h of onset, who had been functionally independent before the onset, were enrolled in this study (cardioembolism [n=926], large artery atherosclerosis [n=583], small vessel occlusion [n=1045], others [n=1289]). Pre-stroke dementia was defined as any type of dementia that was present prior to the stroke. For propensity score (PS)-matched analysis, 320 pairs of patients with and without pre-stroke dementia were also selected. Study outcome was poor functional outcome (modified Rankin Scale 3-6) at discharge. Results: In the total cohort, 330 (8.6%) had pre-stroke dementia. The age (80±8 vs 69±13, year, mean±SD, p<0.01), frequencies of female (46 vs 36, %, p<0.01) and cardioembolism (41 vs 23, %, p<0.01), and NIHSS score on admission (6 [3 - 12] vs 3 [1 - 6], median [interquartile], p<0.01) were higher in patients with pre-stroke dementia than those without the dementia. Poor functional outcome (62 vs 25, %, p<0.01) were more prevalent in patients with pre-stroke dementia than those without the dementia. Multivariable-adjusted analysis showed that pre-stroke dementia was significantly associated with increased risk for poor functional outcome (OR 2.3, 95% CI 1.7-3.2). There were no interactions between pre-stroke dementia and 4 variables (age, sex, stroke subtype, and initial stroke severity [NIHSS≤7 or NIHSS≥8]). In the PS-matched analysis, pre-stroke dementia was still associated with poor functional outcome (OR 4.3, 95%CI 2.1-8.8). Conclusions: Pre-stroke dementia was significantly associated with poor functional outcome at discharge in patients with acute ischemic stroke.

Abstract Funding Acknowledgements Type of funding sources: None. Background Autonomic dysfunction is a common complication of acute ischemic stroke and has been associated with poor functional outcome and increased mortality. We investigated the potential relation between the myocardial washout rate (WOR) of 123I-meta-iodobenzylguanidine (123I-mIBG), as a measure of cardiac sympathetic activity, and functional outcome in acute ischemic stroke.  Methods 38 patients with ischemic stroke (11 females, 72 years old [61-81)), underwent myocardial 123I-mIBG scintigraphy within the first week after stroke onset. Early (10 minutes post-injection (pi)) and late (4 hours pi) planar scans of the thoracic region were made. Regions of interest (ROI) were drawn over the mediastinum and the heart, and heart-to-mediastinum ratio (HMR) was calculated. Myocardial WOR was calculated as follows: (ROI heart early – ROI heart late)/ (ROI heart early) x 100%. Counts were corrected for background and counts in ROI heart late were corrected for decay. Patients were divided in 2 groups: those with a good functional outcome, defined as modified Rankin Scale (mRS) ≤ 2 at 3 months after stroke (i.e., patient is functionally independent), and those with a poor functional outcome, defined as a mRS &gt; 2.  Results Median WOR was 27,4 % (IQR 10,4-43,6). In univariate analysis, poor functional outcome after stroke was associated with age, stroke severity on admission (measured by the National Institutes of Health Stroke Scale (NIHSS)), beta-blocker use before and during hospitalization, WOR and late HMR. In subsequent multivariate analysis WOR (OR 1.087; 95% CI 1.003-1.177, p = 0.042) was an independent predictor of poor stroke outcome even after adjustment for age and NIHSS. Conclusions In patients with acute ischemic stroke, myocardial washout of 123I-mIBG predicts stroke outcome, even after adjustment for age and stroke severity on admission.

Background and Purpose: Little is known about how β-cell dysfunction affects clinical outcome after ischemic stroke. We examined whether β-cell function is associated with clinical outcome after acute ischemic stroke and if so, whether insulin resistance influences this association in a prospective study of patients with acute stroke. Methods: A total of 3590 nondiabetic patients with acute ischemic stroke (mean age, 71 years) were followed up for 3 months. β-Cell function was assessed using the homeostasis model assessment for β-cell function (HOMA-β). Study outcomes were poor functional outcome (modified Rankin Scale score, 3–6) and stroke recurrence at 3 months after stroke onset and neurological deterioration (≥2-point increase in the National Institutes of Health Stroke Scale score) at discharge. Logistic regression analysis was used to evaluate the association between quintile levels of serum HOMA-β and clinical outcomes. Results: The age- and sex-adjusted odds ratios for poor functional outcome and neurological deterioration increased significantly with decreasing HOMA-β levels ( P for trend, <0.001 and 0.001, respectively). These associations became more prominent after adjustment for HOMA-insulin resistance and were substantially unchanged even after further adjustment for other confounders, namely, body mass index, dyslipidemia, hypertension, estimated glomerular filtration rate, stroke subtype, National Institutes of Health Stroke Scale score on admission, and reperfusion therapy (odds ratio [95% CI] for the first versus fifth quintile of HOMA-β, 3.30 [2.15–5.08] for poor functional outcome and 10.69 [4.99–22.90] for neurological deterioration). Such associations were not observed for stroke recurrence. In stratified analysis for the combination of HOMA-β and HOMA-insulin resistance levels, lower HOMA-β and higher HOMA-insulin resistance levels were independently associated with increased risks of poor functional outcome and neurological deterioration. Conclusions: Our findings suggest that β-cell dysfunction is significantly associated with poor short-term clinical outcome independently of insulin resistance in nondiabetic patients with acute ischemic stroke.

Abstract Background The relationship between aminotransferases and cardiovascular outcomes has been inconsistent in previous studies. We aimed to investigate the association of aminotransferases with clinical outcomes after acute ischemic stroke (AIS) or transient ischemic attack (TIA). Methods 17,178 AIS or TIA patients with serum alanine aminotransferase (ALT) levels < 120 U/L were included from the China National Stroke Registry (CNSR) for current analysis. Composite endpoint is comprised of recurrent stroke and all-cause mortality. Poor functional outcome is defined as modified Rankin scale of 3-6. Multivariable logistic regression was used to evaluate the risks of one-year all-cause mortality, recurrent stroke, composite endpoint and poor functional outcome according to increasing sex-specific quintiles of ALT/ aspartate aminotransferase (AST) respectively. Results One-year incidences of all-cause mortality, recurrent stroke, composite endpoint and poor functional outcome were 11.9%, 6.0%, 13.7% and 28.2% respectively in patients with the lowest quintile of ALT, and 7.4%, 3.6%, 9.0% and 17.9% respectively in the highest quintile. Compared with the lowest ALT quintile, the adjusted odds ratios with 95% confidence interval of the highest quintile were 0.55 (0.43-0.70) for all-cause mortality, 0.61 (0.45-0.83) for stroke recurrence, 0.62 (0.49-0.77) for composite endpoint, and 0.67 (0.56-0.80) for poor functional outcome. There was no significant interaction of ALT with age, sex, diabetes, dyslipidemia and alcohol consumption for all outcomes (p for interaction ≥ 0.10). Conclusions Low serum ALT may serve as an independent predictor for all-cause mortality, stroke recurrence, composite endpoint and poor functional outcome after stroke.

Background D‐dimer is involved in poor outcomes of stroke as a coagulation biomarker. We aimed to investigate the associations of the level and increase in D‐dimer between baseline and 90 days with all‐cause death or poor functional outcome in patients after ischemic stroke or transient ischemic attack. Methods and Results We collected data from the CNSRIII (Third China National Stroke Registry) study. The present substudy included 10 518 patients within 7 days (baseline) of ischemic stroke or transient ischemic attack and 6268 patients at 90 days. Poor functional outcome at 1 year was assessed on the basis of the modified Rankin Scale (≥3). Multivariable Cox regression or logistic regression was used to assess the association of D‐dimer levels with all‐cause death or poor functional outcome. D‐dimer levels at 90 days were lower than those at baseline (1.4 µg/mL versus 1.7 µg/mL; P <0.001). Higher baseline D‐dimer level was associated with all‐cause death (adjusted hazard ratio [HR], 1.77; 95% CI, 1.25–2.52; P =0.001) and poor functional outcome (adjusted odds ratio [OR], 1.49; 95% CI, 1.23–1.80; P <0.001) during 1‐year follow‐up. Higher D‐dimer level at 90 days was also associated with poor outcomes independently. Furthermore, an increase in D‐dimer levels between baseline and 90 days was associated with all‐cause death (since 90 days to 1 year after index event) (adjusted HR, 1.99; 95% CI, 1.12–3.53; P =0.019) but not with poor functional outcome (adjusted OR, 1.08; 95% CI, 0.82–1.41). Conclusions Our study shows that high level and an increase in D‐dimer between baseline and 90 days are associated with poor outcomes in patients after ischemic stroke or transient ischemic attack.

Objective The effect of anesthetic management (general anesthesia [GA], conscious sedation, or local anesthesia) on functional outcome and the role of blood pressure management during endovascular treatment (EVT) for acute ischemic stroke is under debate. We aimed to determine whether hypotension during EVT under GA is associated with functional outcome at 90 days. Methods We retrospectively collected data from patients with a proximal intracranial occlusion of the anterior circulation treated with EVT under GA. The primary outcome was the distribution on the modified Rankin Scale at 90 days. Hypotension was defined using two thresholds: a mean arterial pressure (MAP) of 70 mm Hg and a MAP 30% below baseline MAP. To quantify the extent and duration of hypotension, the area under the threshold (AUT) was calculated using both thresholds. Results Of the 366 patients included, procedural hypotension was observed in approximately half of them. The occurrence of hypotension was associated with poor functional outcome (MAP <70 mm Hg: adjusted common odds ratio [acOR], 0.57; 95% confidence interval [CI], 0.35–0.94; MAP decrease ≥30%: acOR, 0.76; 95% CI, 0.48–1.21). In addition, an association was found between the number of hypotensive periods and poor functional outcome (MAP <70 mm Hg: acOR, 0.85 per period increase; 95% CI, 0.73–0.99; MAP decrease ≥30%: acOR, 0.90 per period; 95% CI, 0.78–1.04). No association existed between AUT and functional outcome (MAP <70 mm Hg: acOR, 1.000 per 10 mm Hg*min increase; 95% CI, 0.998–1.001; MAP decrease ≥30%: acOR, 1.000 per 10 mm Hg*min; 95% CI, 0.999–1.000). Conclusions Occurrence of procedural hypotension and an increase in number of procedural hypotensive periods were associated with poor functional outcome, whereas the extent and duration of hypotension were not. Randomized clinical trials are needed to confirm our hypothesis that hypotension during EVT under GA has detrimental effects.
