NCT01074281
This non interventional, multicentric, uncontrolled, prospective, observational study was planned to observe the course of disease in subjects with ISH, who were treated with Eneas.
NCT02064218
First of all to evaluate the relationship between non-conventional biomarkers and essential hypertension; then to evaluate the effects of various anti-hypertensive drugs on blood pressure control and non-conventional biomarkers in naive hypertensive patients
NCT01079962
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.
