Señalan que el estrés oxidativo causado por los radicales libres de oxígeno está implicado en la aterogénesis o formación de la placa de ateroma. Los autores midieron las concentraciones plasmáticas de varias sustancias indicativas del daño causado por los radicales libres en 52 varones y 51 mujeres de 20 a 39 años. Todos ellos estaban sanos, no fumaban y no tomaban medicamentos o vitaminas en el momento del estudio.
La presión arterial, los niveles de colesterol y los de glucosa fueron similares entre ambos sexos, pero los niveles de sustancias que indican el grado de estrés oxidativo fueron superiores entre los varones.
