BACKGROUND It has been reported that elevated levels of serum uric acid are related to hypertension and cardiovascular disease. Recent studies, however, have found little association between hyperuricemia and hypertension. METHODS AND RESULTS The association of serum uric acid with blood pressure was examined in 3,960 Japanese male workers (18-64 years of(More)
Assessing an individual's salt intake is necessary for providing guidance with respect to salt restriction. However, the methods that exist for assessing salt intake have both merits and limitations. Therefore, the evaluation methods should be selected for their appropriateness to the patients and the environment of the medical facilities. The purpose of(More)
BACKGROUND Several observational studies have reported that higher visit-to-visit blood pressure variability is a risk factor for cognitive impairment and dementia. However, no studies have investigated the association of day-to-day blood pressure variability assessed by home blood pressure measurement with the development of dementia. METHODS A total of(More)
OBJECTIVES To determine whether polymorphisms at codon 487 (*1, GAA=Glu; *2, AAA=Lys) of mitochondrial aldehyde dehydrogenase 2 (ALDH2) influence nitroglycerine (glyceryl trinitrate (GTN))-induced vasodilation, and whether GTN or isosorbide dinitrate (ISDN) is a more effective antianginal agent in each ALDH2 genotype. DESIGN A randomised, open-label,(More)
Among the several methods used to assess salt intake, estimating 24 h urinary salt excretion by spot urine seems appropriate for clinical practice. In this study, we investigated variability in urinary salt excretion using spot urine in hypertensive outpatients. Participants included 200 hypertensive patients who underwent spot urinary salt excretion at(More)
Strict control of blood pressure is important to prevent cardiovascular disease, although it is sometimes difficult to decrease blood pressure to target levels. The aim of this study was to investigate the clinical characteristics of resistant hypertension evaluated by ambulatory blood pressure monitoring. One hundred in-hospital patients, whose 24-hour(More)
BACKGROUND The association of morning and evening home blood pressures (HBPs) with carotid atherosclerosis has been uncertain in general populations, so we aimed to investigate it in a general Japanese population.Methods and Results:We performed a cross-sectional survey of 2,856 community-dwelling individuals aged ≥40 years to examine the association of(More)
Objective The purpose of the present study was to assess the prevalence of orthostatic hypotension (OH) and elucidate its associations with the demographic characteristics and the prognosis in elderly subjects with dementia who visited a hospital for elderly daycare. Methods A total of 64 outpatients (44 females) with a mean age of 84±6 years who visited a(More)
BACKGROUND The relationship between salt (sodium chloride) intake and pregnancy-induced hypertension (PIH) remains unclear. The aim of this study was therefore to investigate the current status of salt intake during pregnancy and identify effective predictors for PIH. METHODSANDRESULTS Participants were 184 pregnant women who collected 24-h home urine as(More)
Salt restriction is important for the prevention and treatment of hypertension; however, salt consumption is still high in Japan. Improvements in dietary habits, including salt reduction in childhood, may contribute to the prevention of hypertension. The aim of the present study was to investigate the salt intake of school-aged children and the relationship(More)
