RESUMEN
Stroke has become the leading cause of death and disability in Chinese adults, of which about 70% are ischemic stroke. Previous studies have shown that early enteral nutrition can improve the clinical outcomes of patients with acute stroke. This article reviews the impact of the timing and pathway of enteral nutrition on the clinical outcomes of the patients with acute stroke, in order to provide basis for clinical practice.
RESUMEN
Objective:To investigate the correlation between low-density lipoprotein cholesterol (LDL-C) and hemorrhagic transformation (HT) after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolysis using standard dose alteplase in the First Hospital of Shanxi Medical University from January 2014 to December 2019 were enrolled retrospectively. Head CT scan was performed within 24 h after thrombolytic therapy to identify the occurrence of HT. The demographic and baseline clinical data were compared between the HT group and the non-HT group. Multivariate logistic regression analysis was used to determine the correlation between LDL-C and HT after thrombolysis. Results:A total of 323 patients with AIS who received intravenous thrombolytic therapy were enrolled, their age was 65±12 years (range, 54-78 years), and 219 were males (67.8%). The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 4 (interquartile range, 3-9). Ninety one patients (28.17%) developed HT, of which 8 (2.48%) had symptomatic intracerebral hemorrhage. Univariate analysis showed that there were significant differences in LDL-C, age, baseline NIHSS score, baseline systolic and diastolic blood pressure, baseline fibrin degradation products, and the proportion of patients with atrial fibrillation and stroke etiology between the HT group and the non-HT group (all P<0.05). Multivariate logistic regression analysis showed that lower LDL-C (odds ratio [ OR] 0.531, 95% confidence interval [ CI] 0.358-0.788; P=0.002), higher baseline NIHSS score ( OR 1.063, 95% CI 1.010-1.120; P=0.020) and higher baseline systolic blood pressure ( OR 1.015, 95 CI 1.004-1.026; P=0.008) were the independent risk factors for HT after intravenous thrombolysis in patients with AIS. Conclusions:Low LDL-C is an independent risk factor for HT in patients with AIS after intravenous thrombolysis. The patients with lower LDL-C should be cautious in lipid-lowering therapy and be alert to the occurrence of HT.
