Abstract
BACKGROUND: Intracerebral hemorrhage (ICH) caused by cerebral amyloid angiopathy (CAA) has a high recurrence risk. The Boston criteria, while not designed to predict recurrence, are commonly used for in vivo diagnosis of CAA and have recently been revised to the version 2.0 (v2.0), introducing nonhemorrhagic white matter features. We investigated whether the new v2.0 criteria change ICH recurrence risk in patients with probable CAA. METHODS: We assessed ICH recurrence risk in consecutive patients with ICH and available brain magnetic resonance imaging. Patients with macrovascular or structural causes were excluded. Recurrent ICH was determined using electronic health records and confirmed by neuroimaging. We compared ICH recurrence risk for Boston criteria v2.0 versus v1.5 for probable CAA using survival analysis. RESULTS: Fifty-nine of 443 patients (13.3%) had recurrent ICH over a median follow-up of 5.7 years (2682 patient-years). Thirty-seven out of one hundred two patients (36.3%) with probable CAA according to the Boston criteria v2.0 had recurrent ICH compared with 36/82 patients (43.9%) according to the v1.5 criteria. Patients with probable CAA according to the Boston v1.5 criteria had a higher ICH recurrence rate (10.9 per 100 person-years [95% CI, 7.8-15.1]) compared with those diagnosed by the v2.0 criteria (8.5 per 100 person-years [95% CI, 6.1-11.7]). The 20 patients defined as probable CAA only by the v2.0 criteria had a very low recurrence rate (0.9 per 100 person-years [95% CI, 0.1-6.7]), lower than those diagnosed using the v1.5 criteria (P<0.001). CONCLUSIONS: Our findings suggest a wide spectrum of ICH recurrence risk in patients with probable CAA. Patients with ICH diagnosed with CAA based only on the nonhemorrhagic white matter markers introduced in the Boston v2.0 criteria had a much lower risk of recurrence than those diagnosed with the previous Boston criteria v1.5, comparable to that of patients with ICH not fulfilling any probable CAA criteria.
