Objectives: Many studies showed that platelet reactivity testing can predict ischemic events after carotid stenting or ischemic stroke. The aim of our study was to assess the role of early platelet function monitoring in predicting 90-days functional outcome, stent thrombosis and hemorrhagic transformation in patients with ischemic stroke treated with endovascular procedures requiring emergent extracranial stenting. Materials and methods: We performed a retrospective study on consecutive patients with acute anterior circulation stroke admitted to our hospital between January 2015 and March 2020, in whom platelet reactivity testing was performed within 10 days from stenting. Patients were divided according to validated cutoffs in acetylsalicylic acid and Clopidogrel responders and not responders. Group comparison and regression analyses were performed to identify differences between groups and outcome predictors. Results: We included in the final analysis 54 patients. Acetylsalicylic acid resistance was an independent predictor of poor 90 days outcome (OR for modified Rankin scale (mRS) ≤ 2: 0.10 95% CI: 0.02 – 0.69) whereas Clopidogrel resistance was an independent predictor of good outcome (OR for mRS ≤ 2: 7.09 95%CI: 1.33 – 37.72). Acetylsalicylic acid resistance was also associated with increased 90-days mortality (OR: 18.42; 95% CI: 1.67 – 203.14). Conclusion: We found a significant association between resistance to acetylsalicylic acid and poor 90-days functional outcome and between resistance to Clopidogrel and good 90-days functional outcome. If confirmed, our results might improve pharmacological management after acute carotid stenting.

Abstract

Objectives: Many studies showed that platelet reactivity testing can predict ischemic events after carotid stenting or ischemic stroke. The aim of our study was to assess the role of early platelet function monitoring in predicting 90-days functional outcome, stent thrombosis and hemorrhagic transformation in patients with ischemic stroke treated with endovascular procedures requiring emergent extracranial stenting. Materials and methods: We performed a retrospective study on consecutive patients with acute anterior circulation stroke admitted to our hospital between January 2015 and March 2020, in whom platelet reactivity testing was performed within 10 days from stenting. Patients were divided according to validated cutoffs in acetylsalicylic acid and Clopidogrel responders and not responders. Group comparison and regression analyses were performed to identify differences between groups and outcome predictors. Results: We included in the final analysis 54 patients. Acetylsalicylic acid resistance was an independent predictor of poor 90 days outcome (OR for modified Rankin scale (mRS) ≤ 2: 0.10 95% CI: 0.02 – 0.69) whereas Clopidogrel resistance was an independent predictor of good outcome (OR for mRS ≤ 2: 7.09 95%CI: 1.33 – 37.72). Acetylsalicylic acid resistance was also associated with increased 90-days mortality (OR: 18.42; 95% CI: 1.67 – 203.14). Conclusion: We found a significant association between resistance to acetylsalicylic acid and poor 90-days functional outcome and between resistance to Clopidogrel and good 90-days functional outcome. If confirmed, our results might improve pharmacological management after acute carotid stenting.
