INTRODUCTION: Flow-mediated vasodilatation of brachial arteries, a non-invasive parameter of endothelial function, is correlated with cardiovascular risk factors. An impairment of flow-mediated vasodilatation in the brachial artery is related to the extent of @entity453 . AIMS: The authors examined the relationship between flow-mediated vasodilatation and @entity453 morphology in young @entity1 who had @entity583 . @entity1 AND METHODS: 28 young @entity1 (all @entity1 ) with @entity583 (age 22-40, mean age: 35 years). Coronarography revealed one @entity66 in 16 @entity1 (A group) and multivessel disease in 12 @entity1 (B group). The control group was 14 healthy, young @entity1 (age 18-36 years mean age: 30 years) (C group). The authors examined in all subjects flow-mediated, endothelium-dependent vasodilatation following reactive hyperaemia and @entity1242 induced (NTG), endothelium-independent vasodilatation in the brachial artery with high resolution ultrasound (Acuson 128 X P/10). RESULTS: @entity1 after @entity583 showed @entity73 compared to those of controls. (p < 0.01). Flow-mediated vasodilatation was @entity66 compare to one @entity66 . @entity1242 induced similar degrees of vasodilatation in the @entity583 and control groups. CONCLUSION: Young @entity1 with @entity583 may have impaired endothelium-dependent dilatation and the decrease of flow-mediated vasodilatation is related to the angiographic extent of @entity453 .
