Figure 1. White blood cell (WBC) count, endothelium-dependent dilation (EDD) and nitric oxide (NO) responsiveness.

Figure 1

Middle-aged and older adults (ma/o) with a higher WBC count had (A) impaired EDD, assessed by the peak forearm blood flow (FBF) response to acetylcholine (ACh), and (B) impaired NO responsiveness, assessed by the peak forearm blood flow (FBF) response to sodium nitroprusside (SNP), when compared with ma/o with a lower WBC count and young controls. *P<0.05 vs. lower WBC count group. †P<0.05 vs. young controls. FAV indicates forearm volume.
