Fosinopril and valsartan can significantly inhibit these roles of ox-LDL. The roles of fosinopril and valsartan were not significantly different.Conclusion Fosinopril and valsartan inhibit oxidized LDL-induced expression of ICAM-1 and increase the expression of NO in human umbilical vein endothelial cells, which is one of the mechanisms of antiatherosclerosis.展开更多
