Change From Baseline of Central Systolic Blood Pressure (SBP) at Week 24 (Radial Measurement)
Time frame: Baseline and Week 24
Change From Baseline of Central Systolic Blood Pressure (SBP) at Week 8 (Radial Measurement)
Time frame: Baseline and Week 8
Change From Baseline of Central Pulse Pressure at Week 24 (Radial Measurement)
Time frame: Baseline and Week 24
Change From Baseline of Augmentation Index (Aix) at Week 8
To calculate the blood pressure augmentation index, the inflection point of the pressure curve corresponding to the return of the reflection wave was determined. The ratio between the pressure located above and below the inflection point was calculated.
Time frame: Baseline and Week 8
Change From Baseline of Aix at Week 24
Time frame: Baseline and Week 24
Change From Baseline of Aix Corrected to Heart Rate at Week 24
The heart rate correction was computed by a multivariate model analysis
Time frame: Baseline and Week 24
Change From Baseline of Pulse Wave Velocity at Week 24 (Radial Measurement)
Time frame: Baseline and Week 24
Change From Baseline of Brachial SBP/DBP at Week 24 (Tonometry Center)
Applanation tonometry is a measurement of aortic pressure and vascular stiffness. To assess the central aortic blood pressure, it is necessary to calibrate the applanation tonometry device using the brachial blood pressure.
