The present study attempted to establish whether elevated serum levels of alanine aminotransferase (ALT) and gamma glutamyltransferase (GGT) are independent (of each other) markers of systemic inflammation and oxidative stress as assessed by the plasma levels of C-reactive protein (CRP) and lipid peroxides (lipOX), regardless of the presence of underlying(More)
This observational study of Japanese men without metabolic syndrome (MetS) (age: 41±8 years) was conducted to clarify whether or not heart rate elevation precedes the development of full-blown MetS. MetS was defined based on two modifications of the criteria of the Japanese Expert Committee on the Diagnosis and Classification of Metabolic Syndrome.(More)
We conducted a prospective study to examine the effects of alterations of the metabolic syndrome detection status on the rate of progression of arterial stiffness, which is recognized as a marker of arterial damage and an indicator of cardiovascular risk. Brachial-ankle pulse wave velocity as an index of arterial stiffening was recorded twice over a 3-year(More)
BACKGROUND Although a very simple method of measuring brachial -- ankle pulse wave velocity (baPWV) has become available in a clinical setting, whether baPWV can predict future cardiovascular events remains uncertain. We examined whether baPWV is a predictor of cardiovascular events in patients with acute coronary syndrome (ACS). METHODS AND RESULTS baPWV(More)
Although blood pressure and age are major determinants of arterial stiffness, it is still unclear whether age-related changes in arterial stiffness are similar among subjects with different degrees of severity of hypertension. The present study examined the association between age and pulse wave velocity in subjects with different degrees of hypertension(More)
BACKGROUND Recent evidence suggests that even a slight increase in the plasma level of B-type natriuretic peptide (BNP) may be a marker of cardiovascular risk; however, the mechanisms underlying the association are currently unclear. Because increased arterial stiffness, as reflected by an increase of the pulse wave velocity (PWV) or pulse pressure (PP),(More)
The present study examined whether the menopause augments the age-related increase in brachial-ankle pulse-wave velocity (PWV). In total, 3149 women (ranging in age from 21 to 94 years) undergoing an annual health screening examination were enrolled in a cross-sectional study. Conventional atherosclerotic risk factors were examined, and the brachial-ankle(More)
BACKGROUND Recent studies have suggested that angiotensin-converting enzyme inhibitors (ACEi) have a more pronounced effect on endothelial function (END) than angiotensin II receptor blocker (ARB); however, whether this pronounced effect is more beneficial to patients with insulin sensitivity (IS) remains uncertain. The present study compared the effects of(More)
We examined whether the presence of an increasing number of metabolic syndrome "disorders" was associated with an increasing pulse wave velocity, which is recognized as a marker of cardiovascular risk, and evaluated whether an elevated plasma C-reactive protein level augments this increasing pulse wave velocity. Using a cross-sectional study design,(More)
We examined the influence of metabolic syndrome (MetS) on the relationship between arterial stiffness and the risk of coronary artery disease (CAD). In 396 subjects (age, 63±11 years) who underwent coronary angiography, multiple linear regression analysis demonstrated that the brachial-ankle pulse wave velocity (PWV), but not the presence of MetS, was a(More)
