Abstract:
Objective:To investigate the safety and efficacy of tirofiban therapy in acute cerebral infarction patients having broadened therapeutic time window.Methods:Eighty-four acute cerebral infarction patients having broadened therapeutic time window (the onset time was within 4.5-8 h), admitted to our hospital from January 2016 to May 2018, were chosen in our study. Forty-two patients (treatment group), with the informed consent of himself or his family, received emergent cerebral angiography and treated with tirofiban (the load of tirofiban was pumped via the microductal artery, and the maintenance load was continuously pumped intravenously for 48 h) right after the angiography; the other 42 patients (control group) received emergent cerebral angiography and treated with intensive antiplatelet aggregation therapy right after the angiography; intensive lipid-lowering therapy was given in both groups. The efficacy, safety and follow-up rehabilitation were compared between the two groups. According to the locations of acute cerebral infarction, patients in the treatment group were divided into anterior circulation infarction subgroup ( n=24) and posterior circulation infarction subgroup ( n=18); the efficacy and follow-up rehabilitation were compared between the two subgroups. Results:Patients from the treatment group had significantly lower National Institutes of Health Stroke Scale (NIHSS) scores 48 h, 7 d, and 10 d after treatment, and significantly higher NIHSS score difference values before and after treatment than those from control group ( P<0.05); the proportion of patents having good prognosis (modified Rankin scale [mRS] scores≤2) in the treatment group 3 months after treatment (78.57%) was significantly higher than that in the control group (52.38%), and the Barthel index in the treatment group 3 months after treatment (94.76±11.67) was significantly higher than that in the control group (85.00±15.17, P<0.05). Patients from the posterior circulation infarction subgroup had significantly lower NIHSS scores 48 h, 7 d, and 10 d after treatment, and significantly higher NIHSS score difference values before and after treatment than those from anterior circulation infarction subgroup ( P<0.05); the proportion of patents having good prognosis in the posterior circulation infarction subgroup 3 months after treatment (94.44%) was significantly higher than that in the anterior circulation infarction subgroup (66.67%, P< 0.05). There were no statistically significant differences in platelet count and coagulation tests between the treatment group and control group, and between the posterior circulation infarction subgroup and anterior circulation infarction subgroup ( P>0.05). Conclusion:Tirofiban could improve the prognoses of patients with acute cerebral infarction in broadened therapeutic time window, enjoying high effectiveness and safety, which are more obvious in the posterior circulation infarction.
