The A + genotype of the FGB −455 G/A polymorphism was associated with poor post stroke survival among 55–71 years old postmenopausal women of the Stroke Aging Memory (SAM) study cohort, representing a consecutive series of all Finnish (Caucasian) patients with suspected stroke admitted to Helsinki University Central Hospital during 16 months in 1993–1995. This evidence concerns the gene FGB and stroke disorder.
