APOE genotype, ethnicity, and the risk of cerebral hemorrhage

Abstract

OBJECTIVE: The apolipoprotein E (APOE) polymorphism is an established risk factor for intracerebral hemorrhage (ICH) that is related to cerebral amyloid angiopathy in the white population. Among Asian populations, although ICH represents up to one third of all strokes and has high rates of mortality and morbidity, the role of the APOE polymorphism has not been well studied. METHODS: The Perindopril Protection Against Recurrent Stroke Study (PROGRESS) was a randomized, double-blind, placebo-controlled trial of a blood pressure lowering regimen in subjects with prior cerebrovascular disease. APOE status was determined for 5,671 patients, including 2,148 Asians (38%). RESULTS: During the 3.9 ye..
