Home blood pressure (HBP) monitoring is recommended for assessing the effects of antihypertensive treatment, but it is not clear how the treatment-induced changes in HBP compare with the changes in clinic blood pressure (CBP). We searched PubMed using the terms "home or self-measured blood pressure," and selected articles in which ...

Preliminary evidence suggests that the morning surge (MS) in blood pressure (BP) is an independent predictor of cerebrovascular disease. However, the optimal definition of MS is uncertain. To compare the reproducibility of several MS definitions used in the literature, 132 untreated hypertensives were assessed with ambulatory BP monitoring twice, 2 ...

Long-term blood pressure (BP) progression and its importance as a predictor of clinical outcome have not been well characterized across different periods. We evaluated period trends for 3 BP variables (long-term slope and mean BP during a baseline period of 16 years, and last baseline value) in an earlier period ...

Cytochrome (CYP) 4A11 and CYP4F2 are responsible for renal production of 20-hydroxyeicosatetraenoic acid, a vasoconstrictor and natriuretic substance. The CYP4A11 F434S and CYP4F2 V433M polymorphisms reduce 20-hydroxyeicosatetraenoic acid production in vitro. The aim of the present study was to evaluate the effect of these polymorphisms on blood pressure (BP) levels, ...

No prospective data have been published on whether ambulatory blood pressure (BP) works better than casual measurements in predicting arterial stiffness. This study with 11-year follow-up was launched to evaluate the usefulness of ambulatory intra-arterial BP in predicting pulse wave velocity (PWV). Ninety-seven previously healthy men were recruited from a ...

OBJECTIVE: We reported previously that normotensive Chinese had higher nighttime diastolic blood pressure (BP) compared with non-Chinese. We, therefore, studied the prevalence and characteristics of isolated nocturnal hypertension and its association with arterial stiffness, an intermediate sign of target organ damage. METHODS: We recorded ambulatory BP, the central and peripheral ...

Ambulatory blood pressure monitoring (ABPM) is useful in evaluating cardiovascular risk but requires significant time. The authors examined how closely shortened time intervals correlate with the systolic blood pressure (BP) determined from a full 24-hour ABPM session in 1004 ABPM recordings. After excluding the first hour, Pearson correlations performed for ...

The diagnosis of hypertension among hemodialysis patients by predialysis or postdialysis blood pressure (BP) recordings is imprecise and biased and has poor test-retest reliability. The use of intradialytic BP measurements to diagnose hypertension is unknown. A diagnostic-test study was done with interdialytic ambulatory BP as reference standard. Index BP recordings ...

Association between epistaxis and hypertension is controversial. In this study, we evaluated in hypertensive patients the incidence of epistaxis according to stages of hypertension and compared blood pressure (BP) readings in these episodes to routine readings. Thirty-six patients admitted to the Emergency Department (ED) with epistaxis were enrolled and divided ...

Blood pressure (BP) exhibits a circadian variation characterized by a morning increase, followed by a small postprandial valley and a deeper descent during nocturnal rest. Although abnormal 24-h variability (abnormal circadian variability (ACV)) predicts adverse cardiovascular disease (CVD) outcomes, a 7-day automatic ambulatory BP monitoring (ABPM) and subsequent chronobiologic analysis ...

BACKGROUND: Several studies have suggested that blacks, on average, have a blunted decline in nocturnal blood pressure (BP) as compared with nonblacks. It is unknown whether differences in traditional determinants of BP, specifically diet and obesity, account for observed differences in diurnal patterns. METHODS: We conducted an analysis of the ...
