About this study

The goal of this pilot study is to effectively treat hypertension in subjects with either known or newly diagnosed hypertension and concurrent evidence of diastolic dysfunction. Due to the unique properties of nebivolol, it is hypothesized that there will be improvements in left ventricular (LV) systolic and diastolic function manifesting as increase exercise capacity in this patient population with primarily LV diastolic dysfunction. The present study was performed to determine the effects of nebivolol on blood pressure, exercise tolerance and parameters of left ventricular systolic and diastolic function in a group of hypertensive patients with echocardiographic evidence diastolic dysfunction.

Read the detailed description

Prior to the initiation of Nebivolol and after 10 weeks of Nebivolol therapy, subjects underwent a resting 2D echocardiogram including routine sampling of mitral valve (MV) inflow and LV tissue Doppler imaging as well as a symptom limited exercise treadmill stress test with echocardiographic imaging. Primary endpoints were 1) changes in systolic blood pressure before and after 10 weeks of treatment and 2) changes in exercise capacity as determined by exercise duration and metabolic equivalent (MET) level before and after treatment. Secondary endpoints were changes in exercise hemodynamics and Doppler echocardiographic parameters of LV systolic and diastolic function and quality of life before and after 10 weeks of nebivolol treatment. Subjects completed an EuroQol (EQ-SD) Quality of Life questionnaire which is a standardized measure of health status developed by the EuroQol group as a simple general measure of health at baseline and at conclusion of the 10 week trial period.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NebivololDrug

    Initial dose of 5 mg titrated (doubling of previous dose) to optimal blood pressure. The dose was titrated by doubling the previous dosage to achieve BP less than or equal to 130/80 mm Hg at 2 weeks and 4 weeks. The mean dose of nebivolol used week 4 through week 10 was 7.8 mg. It should be noted that nebivolol was added to the subject's existing stable antihypertensive regimen which included a mean of 2 other medications.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Resting Systolic BP

    Measured: 10 Weeks

  2. Exercise Duration

    Measured: 10 Weeks

  3. Metabolic Equivalent (METS) Level

    METs is a measure of exercise capacity. One MET is defined as 3.5 mL 02 uptake/kg per minute which is the resting oxygen uptake in a sitting position. The Bruce protocol consisted of successive 3 minute stages each of which requires the subject to walk at a faster speed and higher grade of incline. Each stage is assigned a MET level. The achieved exercise capacity in METs has been shown to be predictive in older adult population of survival with higher MET levels associated with improved survival.

    Measured: 10 Weeks

Secondary outcomes (24)
  1. Diastolic BP

    Measured: 10 Week

  2. Peak Stress Systolic BP

    Measured: 10 Week

  3. Peak Stress Diastolic BP

    Measured: 10 Week

  4. Resting Heart Rate

    Measured: 10 Week

  5. Stress Heart Rate

    Measured: 10 Week

  6. Resting EF

    Measured: 10 Weeks

  7. Stress EF

    Measured: 10 Week

  8. Resting Stroke Volume

    Measured: 10 weeks

  9. Stress Stroke Volume

    Measured: 10 week

  10. Resting Cardiac Output

    Measured: 10 week

  11. Stress Cardiac Output

    Measured: 10 week

  12. LV End Diastolic Diameter

    Measured: 10 week

  13. LV End Systolic Diameter

    Measured: 10 week

  14. LV Mass

    Measured: 10 week

  15. Mitral Valve Inflow (E) Velocity

    Measured: 10 Week

  16. Mitral Valve Inflow (A) Velocity

    Measured: 10 Week

  17. Mitral Valve E/A Ratio

    mitral valve doppler E velocity to A velocity

    Measured: 10 Week

  18. Mitral Valve Deceleration Time

    Measured: 10 Week

  19. Mitral Valve Tissue Doppler Velocity (e')

    Measured: 10 Week

  20. Mitral Valve Tissue Doppler Velocity (a')

    Measured: 10 Week

  21. E/e' Ratio

    Measured: 10 Week

  22. Pulmonary Vein Peak Systolic Velocity

    Measured: 10 Week

  23. Pulmonary Vein Peak Diastolic Velocity

    Measured: 10 Week

  24. Quality of Life

    Quality of life was assessed by a visual analogue scale before and after 10 weeks of nebivolol. The subjects self reported assessment of his/her overall health was recorded on a vertical visual analogue scale where 100 is the "best imaginable health state" and 0 is the "worst imaginable health state".

    Measured: 10 Weeks

Questions about this trial

What is this clinical trial studying?

A study testing Nebivolol in people with Hypertension, run by Mercy Research at 1 site in United States.

What does the primary outcome measure?

Resting Systolic BP (time frame: 10 Weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
