Emergency reversal of clopidogrel in the setting of spontaneous intracerebral hemorrhage

Abstract

Objective: To compare outcomes in the setting of spontaneous intracerebral hemorrhage (ICH) in patients taking aspirin (acetylsalicylic acid [ASA]) versus patients taking clopidogrel before hospitalization.

Methods: Patients admitted to the neurosurgical service with a spontaneous ICH while taking an antiplatelet agent were prospectively identified and retrospectively reviewed. Two groups of 28 consecutive patients taking ASA or clopidogrel on admission were ultimately evaluated.

Results: Patients in the clopidogrel group had a mean age of 72.6 years, and patients in the ASA group had a mean age of 65.8 years (P=0.04). Patients taking clopidogrel before hospitalization were significantly more likely than patients taking ASA to experience an increase in hematoma volume (P=0.05). Patients in the ASA group trended toward being discharged to home more frequently than other destinations (P=0.07). The in-hospital mortality rates in this series were 14.3% for the ASA group and 28.6% for the clopidogrel group. However, this association did not reach statistical significance (P=0.19).

Conclusions: In this study, patients taking clopidogrel showed more hematoma expansion, higher in-hospital mortality rates, and a decreased likelihood of a home discharge compared with patients taking ASA alone.
