What are the recommendations for prevention of recurrent ICH?
When stratifying a patient's risk for recurrent ICH may affect management decisions, it is reasonable to consider the following risk factors for ICH recurrence: (1) lobar location of the initial ICH; (2) older age; (3) presence and number of microbleeds on gradient echo MRI; (4) ongoing anticoagulation; and (5) presence of apolipoprotein E 2 or 4 alleles (Class IIa; Level of Evidence B). Additionally, blood pressure should be controlled in all ICH patients (Class I; Level of Evidence A), and measures to control BP should begin immediately after ICH onset (Class I; Level of Evidence A).
