To evaluate the morphological and functional characteristics of the heart in elderly patients with white coat hypertension, we performed an echocardiographic study in 67 elderly individuals older than 60 years: 17 patients with white coat hypertension, 34 patients with true hypertension, and 16 normotensive control subjects. White coat hypertension was defined as a mean 24-hour ambulatory systo...
OBJECTIVES To assess the role of ambulatory blood pressure (BP) monitoring in the diagnosis of hypertension in general practice. BACKGROUND Hypertension is usually diagnosed by means of casual office BP readings. However, ambulatory BP monitoring has shown that a significant proportion of patients diagnosed as hypertensive do not in fact have hypertension. METHOD Sixty-four Indian patients ...
The assessment of white coat hypertension is complicated by the lack of generally agreed-on normal limits of ambulatory blood pressure. To assess the influence of four of these limits on the prevalence of white coat hypertension and the corresponding distribution of left ventricular hypertrophy, we performed 24-hour ambulatory blood pressure monitoring and echocardiographic studies in 346 untre...
The white coat ceremony has become an academic ritual in the health professions: a ceremony that signals a transformation of status from ordinary student to that of one studying to become a health professional. While donning the white coat is a sign of a changed role, the white coat is also a powerful symbol of transformation. White is a symbol of purity, and the white coat symbolizes the purit...
DEFINITION AND PREVALENCE OF WHITE-COAT HYPERTENSION: White-coat hypertension describes the phenomenon of an abnormal blood pressure reading when taken by a physician and a normal reading with ambulatory or home monitoring. The results of studies suggest that the true prevalence of white-coat hypertension may be 20%. The magnitude of the effect using either the oscillometric or the auscultatory...
Several studies have demonstrated that endothelial dysfunction is present in patients with essential hypertension. However, the presence of endothelial dysfunction in patients with white coat hypertension has not been studied. We evaluated the variation in the diameter of the brachial artery produced by flow-mediated dilation after a mechanical stimulus in patients with recently diagnosed mild ...
blood pressure assessed by ABPM and the average reading of systolic blood pressure assessed by the cardiovascular technician was 2.8 mmHg with a white lab coat, and –1.8 mmHg without a white lab coat (P<0.001). This suggests that blood pressure recordings are most erroneous when done by a physician, than by a nurse, and most closely match the gold standard of ABPM when done by a cardiovascular ...
To evaluate the prevalence of 'white-coat' hypertension in patients with newly diagnosed hypertension, 255 subjects (131 males and 124 females) underwent 24-h ambulatory blood pressure monitoring. Patients with 24-h systolic and diastolic blood pressure < 135/85 mmHg were classified as white-coat hypertensives and the remaining as sustained hypertensives. On the assumption that white-coat hyper...
Long-Term Risk in Subjects With White-Coat Hypertension To the Editor: We read with great interest the article by Mancia et al1 clarifying the increased risk of developing sustained hypertension in subjects with white-coat hypertension, compared with normotensive patients, using home blood pressure measurements and ambulatory blood pressure monitoring. This study was performed over a 10-year pe...
TROSZYŃSKA A., CISKA E. (2002): Phenolic compounds of seed coats of white and coloured varieties of pea (Pisum sativum L.) and their total antioxidant activity. Czech J. Food Sci., 20: 15–22. The purpose of this study was to compare the composition and contents of phenolic acids and condensed tannin in the seed coats of white and coloured varieties of pea and to examine the antioxidant properti...
