Abstract:
Objective:To investigate the efficacy and safety of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in patients with maintenance hemodialysis (MHD) and acute ischemic stroke.Methods:The clinical data of 235 patients with acute ischemic stroke receiving MHD were collected in our hospital from March 2018 to October 2021. According to the treatment methods chosen by themselves, these patients were divided into control group ( n=70, only receiving standardized secondary stroke prevention), rt-PA low-dose group ( n=85, receiving rt-PA intravenous thrombolysis, 0.6 mg/kg) and rt-PA standard-dose group ( n=80, receiving rt-PA intravenous thrombolysis, 0.9 mg/kg). The effective rate 24 h after treatment, good efficacy rate 7 d after treatment, and good prognosis rate and mortality 90 d after treatment were used to evaluate the effectiveness. The incidences of intracranial hemorrhage, symptomatic intracranial hemorrhage, and severe extracranial hemorrhage 90 d after treatment were used to evaluate the safety. Results:There was no statistical difference in the good prognosis rate 90 d after treatment among the rt-PA low-dose group, the rt-PA standard-dose group and the control group (71.8%, 68.8%, and 64.3%; P>0.05), but the effective rate 24 h after treatment and good efficacy rate 7 d after treatment in the rt-PA low-dose group and rt-PA standard-dose group (44.7%, 57.7%; 46.3%, 62.5%) were both significantly higher than those in the control group (27.1%, 38.6%; P<0.05). The mortality 90 d after treatment in the rt-PA low-dose group (7.1%) was significantly lower than that in the rt-PA standard-dose group (22.5%) and control group (21.4%, P<0.05). The incidences of intracranial hemorrhage and symptomatic intracranial hemorrhage in the rt-PA low-dose group (8.2%, 3.5%) were significantly lower than those in the rt-PA standard-dose group (22.5%, 16.3%; P<0.05), and the incidences of extracranial complications and gastrointestinal bleeding (5.9%, 1.2%) were significantly lower than those in the rt-PA standard-dose group (18.8%, 10.0%; P<0.05). Conclusion:Intravenous thrombolytic therapy with 0.6 mg/kg rt-PA is recommended for acute ischemic stroke patients receiving MHD.
