Abstract Background: Elevated level of plasma D-dimer increases the risk of ischemic stroke, stroke severity and progression of stroke status, but the association between plasma D-dimer level and functional outcome is unclear. The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcome in patients with acute ischemic stroke (AIS). Methods: This prospective study included 877 Chinese patients with AIS admitted to Renmin Hospital of Wuhan University within 72 hours of symptom onset. Patients were categorized per plasma D-dimer level: Quartile 1(0.24 mg /L), Quartile 2 (0.25–0.56 mg /L), Quartile 3 (0.57–1.78 mg /L), and Quartile 4 (1.78mg /L). Each patient’s medical record was reviewed, and demographic, clinical, laboratory and neuroimaging information was abstracted. Functional outcome at 90 days was assessed with the modified Rankin Scale (mRS). Results: Of 877 patients were included (mean age, 64 years; male, 68.5%), poor outcome was present in 302 (34.4%) patients. After adjustment for potential confounding variables, higher plasma D-dimer level on admission was associated with poor outcome (adjusted odds ratio [aOR] 2.257, 95% CI1.349-3.777 for Q4:Q1; P trend = 0.004). According to receiver operating characteristic (ROC) analysis, the best discriminating factor was a plasma D-dimer level 0.315 mg/L for pour outcome [area under the ROC curve (AUC) 0.657; sensitivity 83.8%; specificity 41.4%]. Conclusion: Elevated plasma D-dimer level on admission was significantly associated with increased poor outcome after admission for AIS, suggesting the potential role of plasma D-dimer as a predictive marker for short-term poor outcome in patients with AIS.

According to receiver operating characteristic (ROC) analysis, the best discriminating factor for poor outcome was a plasma D-dimer level ≥0.315 mg/L (area under the ROC curve 0.657; sensitivity 83.8%; specificity 41.4%). Conclusion: Elevated plasma D-dimer levels on admission are significantly associated with poor outcome after admission for AIS, suggesting the potential role of plasma D-dimer level as a predictive marker for short-term poor outcome in patients with AIS.

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.

Background: Neutrophil-to-lymphocyte ratio (NLR) is an indicator of poor prognosis in acute ischemic stroke (AIS), but associations between NLR with stroke severity and prognosis of intracranial atherosclerotic stenosis (ICAS)-related ischemic events have not been well-elucidated; therefore, we aimed to evaluate whether admission NLR levels correlate with the early stroke severity and short-term functional prognosis in patients with symptomatic intracranial atherosclerotic stenosis (sICAS).Methods: This retrospective study enrolled 899 consecutive patients with AIS attributed to ICAS at Xiangya Hospital stroke center between May 2016 and September 2020. The initial stroke severity was rated by the admission National Institutes of Health Stroke Scale (NIHSS) scores, and the short-term prognosis was evaluated using the 14-day modified Rankin Scale (mRS) scores after stroke onset. A severe stroke was defined as NIHSS >8; an unfavorable functional outcome was defined as mRS scores of 3–6. Admission NLR was determined based on circulating neutrophil and lymphocyte counts.Results: The median admission NLR of all patients was 2.80 [interquartile range (IQR), 2.00–4.00]. In univariate analysis, admission NLR was significantly elevated in patients with severe stroke and poor short-term prognosis. After multivariate adjustment, admission NLR levels were significantly correlated with severe stroke [odds ratio (OR), 1.132; 95% confidence interval (95% CI), 1.038–1.234; P = 0.005] and unfavorable short-term prognosis (OR, 1.102; 95% CI, 1.017–1.195; P = 0.018) in Model 1. In Model 2, the highest NLR tertile (≥3.533) remained an independent predictor of severe stroke (OR, 2.736; 95% CI, 1.590–4.708; P < 0.001) and unfavorable functional outcome (OR, 2.165; 95% CI, 1.416–3.311; P < 0.001) compared with the lowest NLR tertile (<2.231). The receiver operating characteristic (ROC) curves showed the predictability of NLR regarding the stroke severity [area under the curve (AUC), 0.659; 95% CI, 0.615–0.703; P < 0.001] and short-term prognosis (AUC, 0.613; 95% CI, 0.575–0.650; P < 0.001). The nomograms were constructed to create the predictive models of the severity and short-term outcome of sICAS.Conclusions: Elevated admission NLR levels were independently associated with the initial stroke severity and could be an early predictor of severity and poor short-term prognosis in AIS patients with ICAS, which might help us identify a target group timely for preventive therapies.

Introduction: As indicators of the systemic inflammatory response, the neutrophil-to-lymphocyte ratio (NLR) have been proposed to predict the clinical outcome in cardiovascular disease, diabetes, and various malignancies. We assessed the significance of NLR as a predictor of the outcome in patients with acute ischemic stroke. Methods: We retrospectively analyzed the clinical characteristics, laboratory parameters, and NLR in 356 consecutive patients (62.2% men, mean age 65.8±13.0 years) within 3 days after the onset of acute ischemic stroke between July 2012 and March 2015. The NLR was calculated from the differential counts by dividing the neutrophil number by the lymphocyte number at the time of admission. All subjects were divided into four groups according to quartiles of the NLR. Outcomes were measured as 3-month modified Rankin scale (mRS) score. A good functional outcome was defined as a mRS of 0-2 points, whereas a poor outcome was defined as a mRS of >2 points. Multivariate logistic regression analysis was used to assess association among the clinical, inflammatory and serological parameters including NLR and mRS scores. Results: The frequency of atrial fibrillation, heart failure, hypertension, and diabetes, the NIHSS score at admission, and the level of hs-CRP, D-dimer and the NLR were each significantly higher in the poor outcome group (p < 0.05). The cut-off values of NLR and NIHSS score at admission for prediction of the poor outcome were 2.135 (sensitivity 0.864 and specificity 0.533) and 3.5 (sensitivity 0.862 and specificity 0.787), respectively. In age-adjusted analysis, the NLR were significantly correlated with 3-month mRS score (partial r = 0.329, p < 0.001) and NIHSS score at discharge (partial r = 0.301, p < 0.001). Multivariate logistic regression analysis demonstrated that age of ≥65 (OR, 10.2; 95% CI, 3.31-31.21, p < 0.001), presence of diabetes mellitus (OR, 3.3; 95% CI, 1.36-8.12, p = 0.008), NIHSS score of ≥4 (OR, 26.4 95% CI, 9.81-71.15, p < 0.001), NLR of ≥2.135 (OR, 9.2; 95% CI, 3.18-26.4, p < 0.001) were independently associated with poor functional outcome. Conclusion: The NLR is a useful marker for short-term functional outcome in acute ischemic stroke. The NLR may have a role in risk stratification for predicting poor outcome.
