Dynamic analysis techniques may uncover abnormalities in heart rate (HR) behavior that are not easily detectable with conventional statistical measures. However, the applicability of these new methods for detecting possible abnormalities in HR behavior in various cardiovascular disorders is not well established. Conventional measures of HR variability were(More)
OBJECTIVE To compare the effect of candesartan or amlodipine on concentrations of cellular markers of oxidative stress, plasma homocysteine and vitamins in hypertensive patients. METHODS Forty-nine middle-aged patients with untreated stage I-II essential hypertension were recruited in a randomized double-blind double-dummy study to receive a daily dose(More)
OBJECTIVE To compare the effects of amlodipine and candesartan on oxidized low-density lipoprotein (OxLDL), conjugated dienes (CD) and baseline diene conjugation in circulating low-density lipoproteins (LDL-BDC) level during antihypertensive treatment. METHODS Forty-nine patients with untreated mild to moderate essential hypertension were recruited in a(More)
OBJECTIVE Intracellular glutathione in its reduced state is a principal cellular biomolecule with antioxidant activity. Glutathione and homocysteine metabolism are closely associated. As both oxidative stress and hyperhomocystinemia are associated with hypertension, we assessed the relationships between these variables. DESIGN AND SETTING An(More)
Summary. The present study estimates effects of low-dose enteric coated aspirin (ECA) on oxidative stress (OS) markers in a group of middle-aged men (mean age 51.2 ± 6.9 years) free of pre-existing ischemic heart disease. Methods. Serum products of lipid peroxidation, and measures of antioxidative status were detected in 25 healthy men in baseline and after(More)
OBJECTIVE Among apparently healthy women and men, elevated levels of high-sensitivity C-reactive protein (hsCRP) predict the risk of cardiovascular events and may be useful for detecting subclinical atherosclerosis. The aim of this study was to investigate the associations between inflammatory markers, augmentation index (AIx), central pulse pressure and(More)
Impairment of heart rate variability (HRV) has been reported in patients after myocardial infarction (MI). However, it is currently unknown whether the similar alterations of autonomic profile that accompany the first MI will evolve after a recurrent MI. Forty male outpatients with a previous first MI (group I) and 20 age-matched male patients with a(More)
OBJECTIVE Ageing, plasma circulating C-reactive protein (CRP), oxidized low-density lipoprotein (OxLDL) and homocysteine (Hcy) are associated with atherosclerosis. The aim of this study was to evaluate the relationship between age, inflammatory and oxidative stress-related markers with functional and structural changes of the arteries in asymptomatic(More)
BACKGROUND Data about the correlation between augmentation index (AIx), timing of the reflected waveform (T(r)) and inflammatory markers in patients with essential hypertension are not yet well established. The aim of this study was to compare plasma high-sensitivity C-reactive protein (hsCRP), white blood cell count and fibrinogen in hypertensive patients(More)
