Percent change in coronary blood flow, coronary vascular resistance and coronary epicardial diameter in response to (A) endothelium-dependent vasodilation with acetylcholine and (B) endothelium-independent vasodilation with sodium nitroprusside. (C) Percent change in coronary blood flow and coronary vascular resistance in response to adenosine. Subjects with 0/1 component of the MetS in open boxes, 2/3 components of the MetS in speckled boxes and 4/5 components of the MetS in grey boxes. The center line of the box denotes the median value; the extremes of the box, the inter-quartile range; and the bars, the upper and lower limits of 95% of the data. Probability values by 1-way ANOVA.
