What researchers measure

Primary outcomes

  1. Change From Baseline to End of Study in the Mean Sitting Diastolic Blood Pressure (msDBP)

    After the patient had been sitting for 5 minutes, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. The difference of the msDBP at baseline from the msDBP at 8 weeks was calculated using an Analysis of Covariance (ANCOVA) model with baseline as a covariate and treatment and region as two factors.

    Time frame: Baseline, End of Study (Week 8)

Secondary outcomes

  1. Change From Baseline to End of Study in the Mean Sitting Systolic Blood Pressure (msSBP)

    After the patient had been sitting for 5 minutes, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. The difference of the msSBP at baseline from the msSBP at 8 weeks was calculated using an ANCOVA model with baseline as a covariate and treatment and region as two factors.

    Time frame: Baseline, End of Study (Week 8)

  2. Number of Participants With Serious Adverse Events and Adverse Events

    The number of participants with any Serious Adverse Event and the number of participants with Adverse Events in any system organ class. Additional information about Adverse Events can be found in the Adverse Event Section.

    Time frame: 8 weeks

  3. Percentage of Participants Achieving Blood Pressure Control

    After the patient had been sitting for 5 minutes, with the back supported and both feet placed on the floor, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. Blood Pressure control was defined as having a mean sitting Diastolic Blood Pressure \<90 and a mean sitting Systolic Blood Pressure \<140.

    Time frame: 8 weeks

  4. Percentage of Participants Achieving a Diastolic Blood Pressure Response

    After the patient had been sitting for 5 minutes, with the back supported and both feet placed on the floor, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. A Diastolic Blood Pressure Response was defined as a mean sitting Diastolic Blood Pressure (msDBP) \<90 mmHg or a ≥ 10 mmHg reduction in msDBP from baseline.

    Time frame: 8 weeks

  5. Percentage of Participants Achieving a Systolic Blood Pressure Response

    After the patient had been sitting for 5 minutes, with the back supported and both feet placed on the floor, systolic and diastolic blood pressures were measured 3 times using the automatic Blood Pressure monitor and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. A Systolic Blood Pressure Response was defined as a mean sitting Systolic Blood Pressure (msSBP) \<140 mmHg or a ≥ 20 mmHg reduction in msSBP from baseline.
