To compare the effects of nebivolol- with metoprolol-based treatment in patients with mild-to-moderate hypertension and left ventricular hypertrophy (LVH).
Nebivolol vs Metoprolol
2 Nov, 11
ENESYS Study: Nebivolol superior to Metoprolol in Improving Left Ventricular Dysfunction in Hypertensives with LVH
Aim
Study Patients
Fifty patients with mild-to-moderate hypertension (daytime ambulatory blood pressure >140 &/or >90 mmHg) and LVH (left ventricular mass index >125 g/m2 for men and >110 g/m2 for women) and no coronary heart disease (CHD)
Study Groups
- Nebivolol 5 mg + Hydrochlorothiazide 25 mg (n=25)
- Metoprolol 100 mg + Hydrochlorothiazide 25 mg (n=25)
If necessary, quinapril (ACE-I) 10-40 mg/day was added
Assessment
Doppler echocardiography, at rest and during dobutamine stress test
Study Duration
6 months
Results
Nebivolol and Metoprolol reduced BP and Heart Rate to a similar extent

Improvement in LV function was significantly greater with Nebivolol vs. Metoprolol
| Parameters | Nebivolol | Metoprolol |
| Increase in mean Longitudinal ETDE (%) | 16% * | 9% |
| Increase in FPV (%) | 34% * | 0 |
| Increase in ejection time (%) | 5% * | 0 |
| Increase in mean longitudinal displacement (%) | 10% * | 0 |
* P < 0.05 ETDE- Longitudinal early diastolic velocity; FPV - Flow propagation velocity
Nebivolol was better tolerated than Metoprolol
| Adverse Events | Nebivolol | Metoprolol |
| Total | 9* | 18 |
| Fatigue | 4 | 9 |
| Newly developed diabetes | 0 | 3 |
| Erectile dysfunction | 0 | 1 |
* P <0.05
Conclusion
Longitudinal left ventricular function is significantly improved with Nebivolol as compared to Metoprolol.
