Hypertension in pregnancy is an emerging sex-specific risk factor for cardiovascular disease and may lead to more severe hypertension after pregnancy. The objectives of this study were to investigate the frequency of pregnancy-related hypertension among patients referred to a hypertension clinic and its association with the severity of hypertension and(More)
The association between hypertension and headache has been a contentious issue. Most studies have showed that mild hypertension and headache are not associated, but this may not be the case in patients with hypertension classified at more severe stages. We investigated the association between hypertension classified at moderate to severe stages and headache(More)
BACKGROUND The extent of arteriolar narrowing has been recognized as a major sign of end-organ damage in patients with hypertension, but most methods used for its evaluation are highly dependent on the observer. We describe a new semi-automated method to measuring arteriolar-to-venous (A/V) ratio in retinal photography and present its application in the(More)
BACKGROUND Nonpharmacological interventions have been efficacious to control blood pressure (BP) in clinical trials, but their long-term effectiveness in clinical practice was still not documented. METHODS This is a prospective cohort study of 825 patients who received repeated nonpharmacological recommendations to treat hypertension. The outcomes were BP(More)
BACKGROUND In face of variable definitions and sampling criteria, the real prevalence of resistant hypertension in a clinical setting is unknown. OBJECTIVE We investigated the prevalence of true resistant hypertension in an outpatient hypertension clinic. METHODS True resistant hypertension was diagnosed when white coat phenomenon, lack of compliance(More)
BACKGROUND Retinal abnormalities, particularly arteriolar narrowing, are powerful predictors of cardiovascular events. The precision of internists and ophthalmologists in the assessment of retinal vessels widths has been disputed but not evaluated against a technology of edge detection. METHODS Fifty-two patients with hypertension had optic fundi(More)
This paper presents a simulator that analyzes the impacts of the pollutants emission of a new industry insertion on a specific region (in our studies, at Rio Grande City – Brazil). This simulation calculates the atmosphere pollutants concentration and the user can chose between three pollutants dispersion models to simulate: a hypothetic model, ISC model or(More)
