[Doppler sonography assessment of renal arteries against the cardiovascular risk factors in young men--preliminary report].

The purpose of this study was to find out a relationship between cardiovascular risk factors (CVRF) and abnormal results of Duplex Doppler sonography (DD), suggesting renal artery stenosis (RAS). The group of 30 potentially healthy men (age: 35.5 +/- 7.9) randomly selected from population of 200 young men, underwent DD of renal arteries. Abnormal results of DD study, suggesting RAS were found in 19 of 30 men (63%). In this group, occurrence of 3 or more CVRF was significantly higher (15/19) than in the group with normal results of DD (5/11; p < 0.05). The significantly higher (77%; p < 0.05) occurrence of the abnormal DD and the significantly longer (p < 0.001) duration of habitual tobacco smoking were also found out in the group with RR > or = 130/85 mm Hg, in comparison to the group with RR < 130/85 mm Hg. Emphasizing preliminary character of this study and the need of confirmation on larger population, it seems reasonable to consider the assessment of renal arteries with DD in the population of men with cardiovascular risk factors.
