For stroke, however, data are much more limited and restricted to overall stroke. This study investigated the association between fibrinogen and fatal, non-fatal, haemorrhagic and ischaemic stroke in three European cohorts participating in EUROSTROKE. METHODS: EUROSTROKE is a collaborative project among ongoing European cohort studies on incidence and risk factors of stroke. EUROSTROKE is designed as a nested case-control study. For each stroke case, two controls were sampled. Strokes were classified according to MONICA criteria or reviewed by a panel of four neurologists. Recently, data on stroke and fibrinogen became available from cohorts in Cardiff (79 cases/194 controls), Kuopio (74/124), and Rotterdam (62/203). Results were adjusted for age, sex, smoking, and systolic blood pressure. RESULTS: The risk of stroke gradually increased with increasing fibrinogen levels: the odds ratios per quartile increase were 1.08 (95% CI 0.63 to 1.84), 1.91 (1.12 to 3.26) and 2.78 (1.64 to 4.72), respectively. This association was similar for ischaemic (n=138) and haemorrhagic stroke (n=25). Associations between fibrinogen and stroke were similar across strata of smoking, diabetes mellitus, previous myocardial infarction, and HDL cholesterol. The odds ratio, however, tended to increase with increasing systolic blood pressure: from 1.21 among those with a systolic pressure <120 mm Hg to 1.99 among subjects with a systolic pressure of 160 mm Hg or above. CONCLUSION: This analysis of the EUROSTROKE project indicates that fibrinogen is a powerful predictor of stroke. Results did not disclose a differential in this relation of fibrinogen and fatal or non-fatal stroke, or with type of stroke (ischaemic or haemorrhagic). http://repub.eur.nl/res/pub/8395/ 2002-01-01T00:00:00Z BACKGROUND: This study investigated the association between electrocardiographically assessed left ventricular hypertrophy (LVH) and fatal, non-fatal, haemorrhagic and ischaemic stroke in four European cohorts participating in EUROSTROKE. METHODS: EUROSTROKE is a collaborative project among ongoing European cohort studies to investigate differences in incidence of, and risk factors for, stroke between countries. EUROSTROKE is designed as a nested case-control study. For each stroke case, two controls were sampled. Strokes were classified according to MONICA criteria or reviewed by a panel of four neurologists. LVH was assessed according to the Minnesota code or the automated diagnostic MEANS classification system. For this analysis, data on LVH and stroke were available from cohorts in Cardiff (84 cases/200 controls), Kuopio (60/116), Rotterdam (114/334), and Novosibirsk (62/168). Results are adjusted for age and sex. RESULTS: LVH was associated with a twofold increased risk of stroke (odds ratio 2.1 (95% CI 1.3 to 3.5). The risk was particularly pronounced for fatal stroke (4.0 (95% CI 2.1 to 7.9)), whereas the risk was non-significantly increased for non-fatal stroke (1.5 (95% CI 0.8 to 2.7)). The increased risk was more pronounced in smokers: for total stroke 3.5 (95% CI 1.5 to 8.1) versus 1.6 (95% CI 0.8 to 3.1) in non-smokers. Adjustment for systolic blood pressure and body mass index attenuated the associations. LVH was not preferentially associated with a particular type of stroke, although the association with cerebral infarction was stronger. CONCLUSION: This analysis of the EUROSTROKE project indicates that LVH assessed by electrocardiogram is a predictor of stroke. The association seems to be stronger for fatal stroke than for non-fatal stroke and is more pronounced in smokers.
