Endothelium-derived factors in microalbuminuric and nonmicroalbuminuric essential hypertensives
2000
Previous evidence has demonstrated a relationship between growth factors and cardiovascular diseases. This study was aimed at evaluating levels of some endothelium-derived growth factors, and their relationship with microalbuminuria (MAU), in essential hypertension. Ninety-nine mild-moderate essential hypertensives (EH) and 25 healthy controls were studied. All patients underwent 24-h blood pressure monitoring, serum endothelin-1 (ET-1), basic fibroblast growth factor (bFGF) and platelet-derived growth factor (PDGF), and 24-h MAU assays. Later, EH were divided into two subsets consisting of microalbuminurics (MAU >11 microg/min) and nonmicroalbuminurics (MAU <11 microg/min). In microalbumin…
[Arterial hypertension and prediabetes].
2016
Abstract Background and objectives The aim of this study was to assess the factors related to new diabetes in hypertensive. Patients and methods This prospective follow-up study involved 2588 non-diabetic, hypertensive patients. The total follow-up was 15,053 patient-years with a median of 3.4 years (interquartile interval 1.4–6.8). Results During the follow-up, 333 (13%) patients had new diabetes, with a conversion rate of 2.21 (95% confidence interval [CI], 1.98–2.46) 100/patients/year. In a Cox proportional hazard model including baseline characteristics and modifications during the follow-up the three components of metabolic syndrome (excluding blood pressure and glucose values) HR 1.69…
Multichannel functional testing in normal subjects, glaucoma suspects, and glaucoma patients
2012
Purpose.: To evaluate visual function with a novel multichannel functional test named the ATD Multichannel Functional Test. Methods.: This multicenter study had a prospective and cross-sectional design. A total of 186 eyes were included: 42 with glaucoma, 14 glaucoma suspects due to optic nerve characteristics, 25 ocular hypertensives, and 105 normal eyes. All patients performed standard visual fields (Humphrey 24-2) and ATD with eight stimuli configurations: four achromatic (A), two red-green (T), and two blue-yellow (D). To derive main outcome measures, mean sensitivity, mean defect (MD), and pattern standard deviation (PSD) were calculated and compared among groups and types of stimuli w…
Comparative Analysis of Patients with Acute Coronary and Cerebrovascular Syndromes from the National French Hospitalization Health Care System Databa…
2010
<i>Background:</i> Nationwide evaluations of the epidemiology of acute coronary syndrome (ACS) or cerebrovascular syndrome (CVS) are scarce. We aimed to analyze nationwide French data on patients referred to hospital for either ACS or CVS. <i>Methods:</i> Using the French national hospital discharge diagnosis records, all patients hospitalized between 2005 and 2008 with a diagnosis of ACS and CVS based on the ICD-10 were identified. We analyzed vascular risk factors and early outcomes in patients with a single hospitalization for ACS or CVS or for both ACV and CVS in a 2-month time window. <i>Results:</i> 1,187,643 patients were recorded. Among these, 638…
Screening for hypertension in a primary care dental clinic
2009
Objective: The aim of this study was to record blood pressure in patients during their visit to a dental clinic, with the aim of identifying those who have high blood pressure and are unaware of it, as well as those who are aware of their condition but do have their blood pressure under adequate control. Study design: We designed a cross-sectional study which included 154 patients who were seen for a dental checkup at the Primary Dental Care of the Gallician Health Service (SERGAS). All participants completed a standardized medical questionnaire after measuring their systolic blood pressure (SBP) and diastolic blood pressure (DBP), which was conducted using the protocol established by the S…
Inefficient arterial hypertension control in patients with metabolic syndrome and its link to renin-angiotensin-aldosterone system polymorphisms.
2011
There is evidence that uncontrolled arterial hypertension (AHT) in patients with metabolic syndrome (MS) increases cardiovascular risks. The renin-angiotensin-aldosterone system (RAAS) and its polymorphisms apparently confer a genetic risk for uncontrolled AHT. This study aims to investigate the influence of RAAS polymorphisms on AHT control in patients diagnosed with MS. This is a two-stage population-based nested case-control pilot study (n=1514). We differentiated between MS-diagnosed patients and non-MS patients (ATP-III criteria) and selected those individuals diagnosed with AHT from each group (n=161 and n=156, respectively). Those who successfully controlled their AHT (controls) and …

An internet-based self-administered intervention for promoting healthy habits and weight loss in hypertensive people who are overweight or obese: a r…
2015
Background The prevalence of overweight and obesity is on the rise worldwide with severe physical and psychosocial consequences. One of the most dangerous is hypertension. Lifestyle changes related to eating behaviour and physical activity are the critical components in the prevention and treatment of hypertension and obesity. Data indicates that the usual procedures to promote these healthy habits in health services are either insufficient or not efficient enough. Internet has been shown to be an effective tool for the implementation of lifestyle interventions based on this type of problem. This study aims to assess the efficacy of a totally self-administered online intervention programme …
How ineffective hypertension control in subjects treated with angiotensin-converting enzyme inhibitors is related to polymorphisms in the renin-angio…
2009
Abstract Purpose To investigate how genetic polymorphisms of the renin-angiotensin-aldosterone system (RAAS) influence hypertension (HT) control with angiotensin-converting enzyme inhibitor drugs (ACEI). Methods A case–control, cross-sectional population-based nested study (n = 1514) included hypertensive patients treated with ACEI drugs, either alone or with other antihypertensive drugs. We differentiated between those who did not control their HT (cases) with those who did (controls). Each group's characteristics were compared to determine the risk of non-controlled HT associated with RAAS polymorphisms by adjusting for different variables. Results rs11571074 obtained an ORa of 5.26 for T…
Urinary tetrahydroaldosterone as a screening method for primary aldosteronism: a comparative study
2003
Abstract Background The major aldosterone metabolite 3α,5β tetrahydroaldosterone reflects up to 45% of the aldosterone secretion. Its 24-h urinary excretion is likely to provide an accurate index of the daily aldosterone production and to be an indicator for primary aldosteronism (PA). Methods In a prospective study, the validity of tetrahydroaldosterone as a screening test for PA was evaluated in comparison to serum potassium, plasma aldosterone, plasma renin activity, plasma aldosterone/renin activity ratio (PARR), as well as 24-h urinary aldosterone-18-glucuronide and free aldosterone. A total of 111 normotensive individuals, 412 PA patients and 1453 essential hypertensive patients, were…
