| NCT01130168 | The Effects of Antihypertensive Agents on Central Blood Pressure in Healthy Participants and Participants With Hypertension (MK-0000-166) (COMPLETED) | PHASE1 | COMPLETED | 38 | — | — | May 1, 2010 | Nov 1, 2010 | Oct 9, 2015 | - | — |
The augmentation index (AIx) is a measure of systemic arterial stiffness, and is the ratio of augmented aortic pressure (Δ P) to central pulse pressure expressed as a percent. AIx = (ΔP/PP) x 100, where P = pressure and PP = Pulse Pressure. Single dose effects on AIx were estimated as a time-weighted average change from baseline over the 12-hour post single dose observation period. Because heart rate (HR) affects AIx, AIx was corrected to a HR of 75 beats per minute (bpm) as follows: HR-corrected AIx = -0.39 x (75 - HR) + AIx. This value was used for all AIx analyses.

Central SBP was measured by the SphygmoCor® device. Single dose effects on central SBP were estimated as a time-weighted average change from baseline over the 12-hour post single dose observation period.
Central SBP was measured by the SphygmoCor® device. Central SBP was measured at baseline and at 24 hours post dose on Day 28 (Week 4) and expressed as a change from baseline.
Central DBP was measured by the SphygmoCor® device. Single dose effects on central DBP were estimated as a time-weighted average change from baseline over the 12-hour post single dose observation period.

Peripheral SBP was measured by Brachial Sphygmomanometer (standard cuff). Single dose effects on peripheral SBP were estimated as a time-weighted average change from baseline over the 12-hour post single dose observation period.
