Effects of nebivolol in obese African Americans with hypertension (NOAAH): markers of inflammation and obesity in response to exercise-induced stress

We sought to determine whether the antihypertensive drug nebivolol has beneficial effects on vascular markers of inflammation and oxidation in obese African-American patients with hypertension when exposed to exercise-induced stress. Forty-three obese, African-American subjects with hypertension were treated with nebivolol (5–10 mg/day) for 8 weeks. Before treatment the subjects underwent an exercise treadmill study to a level of eight metabolic equivalents. Circulating levels of soluble interleukin-6 (sIL-6), vascular cell adhesion molecule (VCAM-1), adiponectin and leptin were measured at pre-treadmill, and 1 min, 30 min, 60 min and 24 h after treadmill. After the 8-week treatment period, exercise treadmill study and the measurement of markers were repeated. Treatment with nebivolol reduced levels of sVCAM-1 at pre-exercise by 21% and at 1 and 30 min by 12.5 and 20%, respectively ( P
