Study Arms:
- Nebivolol (Type: ACTIVE_COMPARATOR): Systolic and Diastolic blood pressure will be measured before and after randomization to12 weeks of Nebivolol. Forearm blood flow will be measured in response to 100 nmol/min of BQ-123, BQ-123+BQ788 (50 mol/min), Acetylcholine (4.0, 8.0, 16.0 ug/100 mL tissue/min), Sodium Nitroprusside (1.0, 2.0, 4.0 ug/100 mL tissue/min) and BQ-123+BQ-788+Acetylcholine (same doses as above) will be measured before and after the 12 weeks of nebivolol.
- Metoprolol (Type: ACTIVE_COMPARATOR): Systolic and Diastolic blood pressure will be measured before and after randomization to12 weeks of Metoprolol. Forearm blood flow will be measured in response to 100 nmol/min of BQ-123, BQ-123+BQ788 (50 mol/min), Acetylcholine (4.0, 8.0, 16.0 ug/100 mL tissue/min), Sodium Nitroprusside (1.0, 2.0, 4.0 ug/100 mL tissue/min) and BQ-123+BQ-788+Acetylcholine (same doses as above) will be measured before and after the 12 weeks of Metoprolol.
- Placebo (Type: PLACEBO_COMPARATOR): Systolic and Diastolic blood pressure will be measured before and after randomization to12 weeks of placebo. Forearm blood flow will be measured in response to 100 nmol/min of BQ-123, BQ-123+BQ788 (50 mol/min), Acetylcholine (4.0, 8.0, 16.0 ug/100 mL tissue/min), Sodium Nitroprusside (1.0, 2.0, 4.0 ug/100 mL tissue/min) and BQ-123+BQ-788+Acetylcholine (same doses as above) will be measured before and after the 12 weeks of placebo.

Based on this trial design, predict the completion outcome and termination type (if applicable).
