Abstract:

Objective To investigate the correlation between serum homocysteine(Hcy) level and short-term prognosis of acute cerebral infarction patients receiving intravenous thrombolysis. Methods Totally,172 patients with cerebral infarction who received intravenous recombinant human tissue-type fibrinogen activator thrombolytic therapy in Xinxiang Central Hospital from January 2018 to January 2020 were enrolled. The clinical data and laboratory determination results of all the patients were collected. Functional recovery of patients with acute cerebral infarction at 3 months of onset was assessed using the modified Rankin scale(mRS) score. Receiver operating characteristic(ROC) curve was used to determine the optimal cut-off value for patients' functional prognosis. Risk factors for functional prognosis of patients with acute cerebral infarction at 3 months of onset were assessed using binary Logistic regression analysis. Results The patients was classified into low Hcy(≤21.1 μmol/L) group(127 cases) and high Hcy(>21.1 μmol/L) group(45 cases) according to the optimal cut-off value of Hcy(21.1 μmol/L) from the ROC curve. The age,pre-thrombolysis the National Institute of Health Stroke Scale(NIHSS) score and mRS score at 3 months of onset were lower in low Hcy group than those in high Hcy group(P<0.05). The differences in sex,time from admission to thrombolysis,time from onset to thrombolysis,blood glucose,D-dimer,international normalized ratio(INR),hemoglobin,past history and infarct volume and location between the 2 groups had no statistical significance(P>0.05). The results of multivariate binary Logistic regression analysis showed that age >75,pre-thrombolysis NIHSS score >7 and Hcy >21.1 μmol/L were independent risk factors for poor functional prognosis in patients with acute cerebral infarction at 3 months of onset [odds ratios(OR) were 3.12,4.64 and 2.04,95% confidence intervals(CI) were 1.54-8.21,1.75-10.02 and 1.09-7.43]. Conclusions Elevated serum Hcy levels are correlated with poor functional prognosis at 3 months of onset in patients with acute cerebral infarction receiving intravenous thrombolysis.
