Brief Summary

Antihypertensive drugs aim to reduce blood pressure (BP) either through decrease of the total peripheral resistance through vasodilatation at the level of arterioles (microcirculation) or by decreasing the cardiac output through reduction of the stroke volume or heart rate or both. On the other hand, all antihypertensive drugs might potentially decrease arterial stiffness passively with the reduction of the distending pressure or with the resynchronization of the reflected pressure wave. With theses potential mechanisms, it is also expected that these drugs might exert a favorable effect on pulse pressure amplification between central and peripheral arteries. However, there is solid evidence that the widely applied antihypertensive drugs have differential effect on brachial and central BP. Several reports in the past have confirmed the potential hypothesis that beta blockers decrease central BP less than the observed reduction at the level of the brachial artery. It has been hypothesized that deceleration of heart rate and the re synchronizing the reflected pressure wave earlier in the systolic phase seems to be the leading cause of non-favorable effect of beta blockers on central BP, these effects might be partially counterbalanced in beta blockers with high beta-1 selectivity resulting in less peripheral vasoconstriction properties.

Outcome Measures

Primary Outcomes (2)

  • Change From Baseline in Aortic Pulse Pressure (APP) in Intention to Treat (ITT) Population at Week 12

    The APP was calculated as aortic systolic pressure minus aortic diastolic pressure. The change in APP at Week 12 was calculated as APP at Week 12 minus APP at baseline.

    Baseline and Week 12

  • Change From Baseline in Aortic Pulse Pressure (APP) in Per Protocol (PP) Population at Week 12

    The APP was calculated as aortic systolic pressure minus aortic diastolic pressure. The change in APP at Week 12 was calculated as APP at Week 12 minus APP at baseline.

    Baseline and Week 12

Secondary Outcomes (9)

  • Change From Baseline in Aortic Blood Pressure (BP) at Week 4 and Week 12

    Baseline, Week 4 and Week 12

  • Change From Baseline in Aortic Augmentation Index (AIx) at Week 4 and Week 12
