Review of Toyoda K, et al . Dual antiplatelet therapy using cilostazol for secondary prevention in patients with high-risk ischemic stroke in Japan. Lancet Neurol. 2019 Jun;18(6):539-548

摘要

Background: Prior meta-analyses showed that treatment with cilostazol, with or without aspirin, significantly reduced the incidence of recurrent ischemic stroke, occurrence of hemorrhagic stroke, and frequency of other serious vascular adverse events. Methods: This review highlights the value of the randomized controlled trial (RCT) by Toyoda et al. entitled, “Dual antiplatelet therapy using cilostazol for secondary prevention in patients with high-risk ischemic stroke in Japan: a multicenter, open-label, randomized controlled trial.” Here, dual therapy consisting of cilostazol and another antiplatelet agent was used to prevent secondary ischemic stroke in high-risk Japanese patients. Results: Patients on dual therapy consisting of cilostazol/aspirin or cilostazol/clopidogrel had significantly lower frequencies of recurrent stroke. However, there were significant differences in the incidence of attendant hemorrhagic complications utilizing mono or dual therapy. Conclusion: This RCT demonstrated the safety of dual therapy, consisting of cilostazol/aspirin or cilostazol/ clopidogrel, in preventing secondary ischemic stroke in a high-risk Japanese population. Further studies are required to generalize these findings to other patient populations worldwide.
