What is the risk of ischemic stroke with and without antithrombotic treatment following ICH?
The risk of ischemic stroke with and without antithrombotic treatment following ICH must be weighed carefully. The risk of ischemic stroke in people with AF is typically estimated using instruments such as the CHA2DS2-VASC score, and it seems reasonable to use this score in populations of ICH survivors. The future risk of ICH is highly variable, with annual recurrence risks ranging from 1.8% to 7.4%. The risk of recurrence has been reported to be higher for lobar ICH than after deep ICH, a finding which is probably related to different underlying small vessel diseases that cause ICH in the different locations.
