ABSTRACT
SUMMARY OBJECTIVE Our aim is to determine whether radiation affects the endothelial function of hospital staff working in the radiation unit for diagnostic and therapeutic purposes. We have evaluated endothelial function with vascular imaging parameters such as flow-mediated dilatation (FMD) and aortic stiffness index (ASI). METHODS A total of 75 employees, 35 of whom are exposed to radiation due to their profession and 40 as the control group, were included in our single-centered study. Demographic data, FMD, aortic stiffness, and echocardiographic findings of the two groups were compared. RESULTS There were no significant differences in demographic data. Median FMD values tended to be lower in the radiation exposure group [7.89 (2.17-21.88) vs. 11.69 (5.13-27.27) p=0.09]. The FMD value was significantly lower in the catheter laboratory group than in the radiation-exposed (p=0.034) and control (p=0.012) groups. However, there was no statistically significant difference between the non-catheter lab radiation exposed group and the control group (p=0.804). In addition, there was no statistically significant difference in the ASI value between the groups (p=0.201). CONCLUSION We have found that FMD is decreased among hospital staff working in radiation-associated areas. This may be an early marker for radiation-induced endothelial dysfunction.
RESUMO
RESUMO OBJETIVO O nosso objetivo é determinar se a radiação afeta a função endotelial de funcionários do hospital que trabalham em unidades com exposição à radiação para fins diagnósticos e terapêuticos. Avaliamos a função endotelial com parâmetros de imagens vasculares, tais como dilatação fluxo-mediada (FMD) e o índice de rigidez aórtica (ASI). METODOLOGIA Um total de 75 funcionários, 35 expostos à radiação devido à sua ocupação e 40 como grupo de controle, foram incluídos em nosso estudo monocêntrico. Os dados demográficos, de FMD, rigidez aórtica e ecocardiográficos dos dois grupos foram comparados. RESULTADOS Não houve diferenças significativas nos dados demográficos. Os valores médios de FMD, em geral, foram mais baixos no grupo de exposição à radiação [7,89 (2,17-21,88) e 11,69 (5,13-27,27) p=0,09]. O valor de FMD foi significativamente menor no grupo laboratorial com cateter do que no exposto à radiação (p=0,034) e no de controle (p=0,012). No entanto, não houve diferença estatisticamente significativa entre o grupo laboratorial sem cateter e exposto à radiação e o grupo de controle (p=0,804). Além disso, não houve diferença estatisticamente significativa quanto ao valor de ASI entre os grupos (p=0,201). CONCLUSÃO Observamos que a FMD é menor entre funcionários que trabalham em setores hospitalares associados à radiação. Isso pode ser um marcador inicial de disfunção endotelial induzida por radiação.
