Text: Folic acid reduced homocysteine concentrations (10. 8 + / - 0. 6 vs. 8. 2 + / - 0. 5 micromol L-1, P < 0. 001) and enhanced endothelium-dependent vasodilatation during each acetylcholine infusion rate (ratio between the FABF in the infused and control arm during increasing infusion rates at baseline 1. 09 + / - 0. 03 vs. 1. 41 + / - 0. 09 after treatment, P < 0. 01 ; 1. 39 + / - 0. 07 vs. 1. 83 + / - 0. 12, P < 0. 01 ; 1. 65 + / - 0. 16 vs. 2. 72 + / - 0. 36, P < 0. 05) whilst endothelium-independent vasodilatation was unaffected.
