OBJECTIVE To evaluate in hypertensive patients (pts) with similar peripheral blood pressure (BP) whether different antihypertensive treatments have different influences on aortic stiffness, aortic central pressures and aortic wave reflections. METHODS In a cross-over study 41 nondiabetic hypertensives (21 women, age 35-60 yrs) were evaluated after(More)
BACKGROUND Portugal has one of the highest mortality rates from stroke, a high prevalence of hypertension and probably a high salt intake level. AIM To evaluate Portuguese salt intake levels and their relationship to blood pressure and arterial stiffness in a sample of four different adult populations living in northern Portugal. METHODS A(More)
BACKGROUND We investigated viscoelastic properties of the arterial wall in women with previous preeclampsia (PE) compared to those with normal pregnancy (NP). METHODS In a cross-sectional study 45 women with previous PE and 55 with NP were included, matched for age (PE 38±6 vs. NP 38±5 years, NS) and body mass index: (PE 25±4 vs. NP 26±4 kg/m(2), NS)(More)
INTRODUCTION It is still controversial whether subjects with white-coat hypertension (WCHT) exhibit higher cardiovascular risk compared to normotensive subjects (NT). In subjects with WCHT it is not known whether the abnormal blood pressure (BP) reaction in the office also occurs at other times of day, particularly on arising and immediately after waking,(More)
OBJECTIVE Our aim was to examine the association of ambulatory blood pressure monitoring (ABPM) and central blood pressure (CBP) data in a large set of normotensive and hypertensive patients and its relation with pulse wave velocity (PWV). PATIENTS AND METHODS This cross-sectional study was carried out in a single centre and included 2864 individuals who(More)
OBJECTIVE To evaluate the relationship between carotid-femoral pulse wave velocity (PWV) and office and ambulatory blood pressure (ABP) and other cardiovascular risk factors and to determine the discriminatory value of PWV in a large population including normotensive subjects (NT), white-coat normotensives (masked hypertension) (WCNT), and white-coat(More)
BACKGROUND Cigarette smoking is one important preventable cause of cardiovascular illness that has been associated with increased stiffness of large arteries and wave reflection, which are independent predictors of cardiovascular disease. METHODS We investigated the effect of a 6-month quitting smoking programme on aortic stiffness, central pressure and(More)
OBJECTIVE High salt intake has been associated with the development of arterial hypertension, but it still remains controversial as to how salt consumption relates with central haemodynamics and central pressures. For interventional purposes, it is crucial to identify the main food categories that contribute toward high salt consumption. METHODS In 638(More)
OBJECTIVE To evaluate in a large population the relationship between cardiovascular target organ damage and values of the night-to-morning rise of systolic blood pressure (MR-BP), the morning surge of BP at the moment of rising (BP surge) and daytime BP variability (standard deviation [SD] of daytime BP). METHODS This was a cross-sectional study,(More)
BACKGROUND It is unclear whether the assumed inferiority of atenolol to reduce central (aortic) blood pressure (BP) extends to other β-blockers with vasodilating properties and, within that scope, how these drugs differ from the angiotensin receptor blockers (ARBs). METHODS In a retrospective study, we compared three groups of hypertensive patients (aged(More)
