Abstract:
Objective:To investigate the safety and efficacy of intravenous thrombolysis with recombinant human tissue-type plasminogen activator (rt-PA) in acute cerebral infarction combined with hyperglycemia under the guidance of glycosylated hemoglobin A 1c (HbA1c) level in the elderly. Methods:A retrospective study was performed. Two hundred and sixty-two elderly patients with acute cerebral infarction, admitted to our hospital from January 2018 to June 2021, were chosen in this study. Patients with admission blood glucose of 2.8-22.2 mmol/L and accepted intravenous thrombolysis with standard dose of rt-PA were enrolled into control group; patients with admission blood glucose over 22.2 mmol/L and HbA1c less than 15.59% were enrolled into experimental group. The patients in the experimental group were subdivided into conservative treatment group ( n=63), rt-PA low-dose group (0.6 mg/kg, maximum dose 60 mg, n=67) and rt-PA standard dose group (0.9 mg/kg, maximum dose 90 mg, n=60) according to whether these patients received rt-PA intravenous thrombolysis or not and dosage of rt-PA. The response rate 24 h after treatment and short-term prognosis 7 d after treatment were evaluated by referring to the treatment effectiveness evaluation criteria developed by NINDS clinical trials. The long-term prognosis was evaluated by modified Rankin Scale (mRS) 90 d after treatment. The safety evaluation indexes mainly included incidences of intracranial hemorrhage and complications within 90 d of treatment. Results:(1) The response rate 24 h after treatment showed significant differences among the 4 groups ( P<0.05): that in the control group, rt-PA low-dose group, and rt-PA standard dose group was significantly higher than that in the conservative treatment group ( P<0.05); the good prognosis rate 7 d after treatment showed significant differences among the 4 groups: that in the control group, rt-PA low-dose group, and rt-PA standard dose group was significantly higher than that in the conservative treatment group ( P<0.05). (2) Ninety d after treatment, 59 patients (81.9%), 46 (73.0%), 53 (79.1%), and 46 (76.7%) in the control group, conservative treatment group, rt-PA low-dose group, and rt-PA standard dose group had good prognosis, without significant differences among each group ( P>0.05). (3) There was significant difference in the incidence of cerebral hemorrhage within 90 d of treatment among the 4 groups ( P<0.05): that in the rt-PA standard dose group and rt-PA low-dose group was significantly higher than that in the control group and conservative treatment group, and that in the rt-PA standard dose group was significantly higher than that in the rt-PA low-dose group ( P<0.05). Seven patients (9.7%), 8(12.7%), 5(7.5%), and 13(21.7%) in the control group, conservative treatment group, rt-PA low-dose group, and rt-PA standard dose group had extracranial complications: the incidence of extracranial complications in the rt-PA low-dose group was significantly lower than that in the rt-PA standard-dose group ( P<0.05). There were 7 kinds of residual neurological dysfunction in 4 groups within 90 d of treatment, among which, numbness, weakness and speech impairment were the most common. Conclusion:Elderly acute cerebral infarction patients with admission blood glucose over 22.2 mmol/L can receive rt-PA treatment when HbA1c is less than 15.59%, and 0.6 mg/kg dosage is recommended.
