Summary:

Study title: Effects of Nebivolol on subclinical left ventricular dysfunction. A comparative study against Metoprolol. (ENESYS study)
Study phase: 3
Study design (parallel, cross-over, etc.), randomisation and blinding procedures, type of control (placebo or active): randomised, parallel, active-controlled, open label
Study treatment(s)/drug(s): Nebivolol versus Metoprolol

Patients:

characteristics: patients with hypertension and left ventricular hypertrophy
planned total number: 50

Study duration:

total enrolment period (months): 18
treatment period (months): 6
follow up period (months): 6

Total study duration (months): 24

Number of Centres: 1
Country(ies): Romania (RO)
STUDY OBJECTIVES

PRIMARY:

Longitudinal myocardial velocities at rest (assessed by tissue Doppler echocardiography)
Systolic functional reserve (calculated as the absolute and relative increase of the myocardial systolic velocities at peak stress from rest)
Brain natriuretic peptide (BNP, NT-pro BNP) after a 6-months period of treatment with nebivolol versus metoprolol. An improvement of more than 20% of the myocardial resting velocities of systolic functional reserve is considered to be clinically relevant. The working hypothesis is that the improvement of subclinical left ventricular dysfunction after 6 months of treatment is going to be greater in patients who receive nebivolol than in those who receive metoprolol.

SECONDARY:

Global systolic function (ejection fraction)
Radial myocardial velocities
Right ventricular function
Global diastolic function
Left ventricular mass index
