Fast-food meal reduces peripheral artery endothelial function but not cerebral vascular hypercapnic reactivity in healthy young men

Figures

• 

  Figure 1. (A) Peak CVCI (% Baseline) at Pre, 2 h, and 4 h in control (open bars) and FFMeal (solid bars) conditions. No significant differences were detected across time or condition (interaction: P = 0.33). (B) ∆PETCO 2 from resting levels at peak CVCI indicating that peak CVCI occurs at a consistent ∆PETCO 2 (time x condition: P = 0.10). (C) There was no difference in reactivity (∆CVCI·∆PETCO 2 −1) across time or condition (P = 0.88). All data are expressed as Mean ± SD.

• 

  Figure 2. (A) The change in BA FMD from Pre at 2 h and 4 h in control (open bars) and FFMeal (solid bars) conditions. Following FFMeal, BA FMD was reduced at 2 h compared to control. All data are expressed as Mean ± SD. (B) The relationship between the change in serum [TG] and BA FMD from Pre to 2 h indicating a reduction in BA FMD with an increase in serum [TG].

  Figure 3. (A) Peak reactive hyperemia blood velocity in the brachial artery following 5 min of occlusion in control (open bars) and FFmeal (solid bars). (B) Reactive hyperemia AUC (i.e., total blood flow) during the first 120 sec post cuff release. All data are expressed as Mean ± SD. Neither time nor condition significantly affected either index of peripheral microvascular function.
