ABSTRACT
Objective:To investigate the correlation between stress hyperglycemia ratio (SHR) and poor outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke.Methods:From January 2019 to October 2022, patients with acute ischemic stroke received endovascular treatment and successful recanalization in the Second People’s Hospital of Lianyungang were included retrospectively. SHR was defined as the fasting blood sugar and glycosylated hemoglobin ratio. At 90 d after procedure, the outcome of patients was evaluated using the modified Rankin Scale score. 0-3 was defined as good outcome, and >3 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent risk factor for poor outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of SHR for 90 d poor outcome in patients with successful recanalization after endovascular treatment.Results:A total of 159 patients were enrolled, including 98 males (61.6%), aged 69.8±8.9 years old. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 12.6±4.3, and SHR was 1.17±0.46. One hundred and five patients (66.0%) had good outcome, while 54 (34.0%) had poor outcome. There were statistically significant differences in SHR, fasting blood glucose, glycosylated hemoglobin, baseline NIHSS score and the proportion of patients with poor collateral circulation and symptomatic intracranial hemorrhage between the poor outcome group and the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that SHR was an independent predictor of poor outcome (odds ratio 2.254, 95% confidence interval 1.136-4.278; P<0.001). The ROC curve analysis showed that the area under the curve of SHR for predicting poor outcome was 0.726 (95% confidence interval 0.648-0.804; P<0.001), which was higher than fasting blood glucose and glycosylated hemoglobin. The optimal cutoff value for SHR was 1.21, and the sensitivity and specificity for predicting poor outcomes were 66.23% and 75.82%, respectively. Conclusion:SHR is associated with the poor outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke and can be used as a potential predictor.
ABSTRACT
Objective To investigate the predictive value of serum lipoprotein-associated phospholipase A2(Lp-PLA2) for the outcomes in patients with large atherosclerotic stroke (LAA). Methods Patients with LAA admitted to the Second People's Hospital of Lianyungang from March 2015 to January 2018 were enrolled retrospectively. The outcomes were evaluated by the modified Rankin Scale at 90 d after onset, 0-2 was defined as good outcome. Multivariate logistic regression analysis was used to identify the independent risk factors for poor outcome. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of Lp-PLA2for outcomes. Results A total of 121 patients with LAA were enrolled, including 64 males (52.9%) and 57 females (47.1%), aged 63.5 ±9.5 years; 72 (59.5%) had good outcome and 49 (40.5%) had poor outcome. The differences were statistically significant in the proportion of diabetic patients (26.4% vs.65.3%; χ2=18.110, P<0.001) and glycated hemoglobin ( 6.39% ±2.33% vs. 7.58% ±3.12%; t=1.663, P=0.041), baseline National Institutes of Health Stroke Scale (NIHSS) score (5 [3-6] vs.10[7 -14]; Z= -7.498, P< 0.001), and Lp-PLA2(194.7 ±84.3 μg/L vs.291.4 ± 82.6 μg/L; t= -5.447, P<0.001) between the good outcome group and the poor outcome group. Multivariate logistic regression analysis showed that diabetes ( odds ratio [ OR] 1.215, 95% confidence interval [CI] 1.102-1.601; P=0.046), glycosylated hemoglobin ( OR 2.275, 95% CI 1.065-4.865; P=0.037), baseline NIHSS score ( OR 2.113, 95% CI 1.585-2.734; P=0.015), and Lp-PLA2(OR 5.183, 95% CI 3.203-8.134; P<0.001) were the independent risk factors for poor outcomes in patients with LAA. ROC analysis showed that the area under the curve of Lp-PLA2predicting poor outcome was 0 .792 (95% CI 0.713-0.872); the optimal cut-off value was 260.5 μg/L, the sensitivity for predicting poor outcome was 79.6%, and the specificity was 84.7%. Conclusion The higher serum Lp-PLA2level is an independent predictive factor for poor outcome in patients with LAA. It has a higher predictive value for poor outcome.
ABSTRACT
Objective To investigate the relationship between the right-to-left shunt(RLS)detected with contrast-enhanced transcranial Doppler (c-TCD) and recurrent stroke in patients with cryptogenic stroke.Methods The consecutive patients w ith ischemic stroke w ere enrol ed. The patients w ith cryptogenic stroke w ere screened according to the TOAST criteria. They w ere divided into either a RLS positive group or a RLS negative group according to the c-TCD findings, and then they w ere fol ow ed up for a period of one year. They w ere also divided into a recurrent group and a non-recurrent group according to w hether they had recurrence or not. Results A total of 118 patients w ith cryptogenic ischemic stroke w ere enrol ed, including 46 in the RLS positive group, 72 in the RLS negative group, 10 in the recurrent group, and 108 in the non-recurrent group. There w ere no significant differences in demographic and baseline data betw een the RLS negative group and the RLS positive group. There w ere significant differences in RLS positive rate (7/10 vs.39/108; P=0.046) and proportion of patients with server RLS (2/10 vs.1/108; P=0.019) betw een the recurrent group and the non-recurrent group. Multivariate logistic regression analysis show ed that the positive RLS w as an independent predictor of recurrent stroke (odds ratio 4.896, 95% confidence interval 1.135-21.120;P=0.033). Conclusions The positive RLS may be an independent risk factor for the recurrence in patients w ith cryptogenic ischemic stroke.
