Association of Endothelial Function with Parental Hypertension in Normotensive-Obese African-American Women: A Pilot Study

Figure 1

Effect of parental histories of hypertension on flow-mediated dilation (FMD) before and after an exercise treatment. Bars show the means ± 95% confidence intervals of percent changes in brachial artery blood flow during reactive hyperemia induced by blood flow occlusion. These FMD measurements were made 20 min before and 20 min after 30 min of aerobic exercise at 60% of predetermined peak oxygen consumption in matched groups of normotensive-obese, young-adult African-American women, with and without parental histories of hypertension (PH+ comparison group, PH- control group, n=20). The upper panel compares the FMD before and after the exercise treatment. The lower panel compares the FMD after the exercise treatment.
