The authors hypothesized that individuals born in the early 20th century who experienced the hottest and driest summers during infancy would be more likely to have suffered severe infant diarrhea and dehydration, and consequently have had higher blood pressure in adulthood, than those who experienced cooler and wetter summers. In ...

BACKGROUND: Few data exist to evaluate whether Tai Chi (TC) training improves physical performance and hemodynamic outcomes more than a wellness education (WE) program does among older fallers transitioning to frailty. METHODS: This 48-week randomized clinical trial was provided at 10 matched pairs of congregate living facilities in the Atlanta ...

As there is growing evidence that hypertensive pregnancy disorders are associated with a risk of cardiovascular diseases later, the resolution of hypertension postpartum (PP) is of high clinical significance. However, there is little knowledge about the factors that influence this normalization. The objectives of our study were (a) to investigate ...

Several previous studies have demonstrated sex differences in cardiovascular autonomic control in healthy young women, but little is known about the regulation of blood pressure in hypertensive elderly women, who have the greatest risk of adverse cardiovascular events. Therefore, we examined sex differences in physiological responses to upright tilt in ...

OBJECTIVES: The goal of this study was to determine the relationship between resting blood pressure (BP) and C-reactive protein (CRP) in a multi-ethnic cohort of men and women from the Multi-Ethnic Study of Atherosclerosis (MESA). BACKGROUND: Several investigators have observed elevated levels of CRP in individuals with hypertension. Hypertension prevalence ...

Progesterone has a high affinity for the mineralocorticoid receptor and is an antagonist of aldosterone. Almost all synthetic progestogens are devoid of an antimineralocorticoid effect, and are unable to antagonize the salt-retaining effect of estrogens. This property could be one cause of the weight gain and increase in blood pressure ...

Numerous indexes derived from polysomnography are available to characterize sleep-disordered breathing, with no consensus over which measures best predict clinical outcomes. This study addresses the relative merits of using alternative polysomnography indexes by characterizing the consistency and strength of the association of each index with blood pressure and hypertension. Cross-sectional ...

We previously showed that, in comparison with term healthy parturients, patients with severe preeclampsia had a less frequent incidence of spinal hypotension, which was less severe and required less ephedrine. In the present study, we hypothesized that these findings were attributable to preeclampsia-associated factors rather than to a smaller uterine ...

OBJECTIVE: Since beta2-adrenergic receptors are important regulators of blood pressure, genetic variation in this receptor could explain risk of elevated blood pressure in selected individuals. We tested the hypothesis that Gly16Arg, Gln27Glu, and Thr164Ile in the beta2-adrenergic receptor gene associated with elevated blood pressure. METHODS: We genotyped 9185 individuals from ...

A growing body of evidence indicates that pregnancy-induced hypertension can be associated with features of insulin resistance. However, the impact of lower than hypertension-levels of blood pressure in pregnancy on the subsequent risk of developing abnormal glucose tolerance (AGT), has not been examined. We investigated women born in the years ...

Gender has been reported to influence baroreflex heart rate regulation and baroreflex blood pressure buffering. We tested the hypothesis that gender influences baroreflex regulation of heart rate and sympathetic vasomotor tone. We recruited 32 normal-weight healthy subjects (17 men and 15 women). ECGs for heart rate, brachial and finger blood ...

Langenberg Claudia - - 2005
BACKGROUND: Previous cross-sectional analyses of this cohort have shown that short height and leg length are associated with higher pulse pressure and systolic blood pressure in middle age. It is unclear how these adult measures of childhood growth influence the change in blood pressure as it increases with age. METHODS: ...

The aim of the study was to assess the effect of continuous hormone therapy (HT) for 1 yr on pulse wave analysis and central aortic pressure in healthy postmenopausal women. Sixty-five healthy postmenopausal women were randomly allocated to receive either conjugated equine estrogens 0.625 mg plus medroxyprogesterone acetate 5 mg ...

There is growing evidence that low-grade chronic inflammation, as reflected by the raised serum concentration of C-reactive protein, might be a risk factor for hypertension, in particular in women. We therefore investigated gender-specific associations of systolic and diastolic blood pressure and pulse pressure with serum C-reactive protein concentration in a ...

BACKGROUND: Membrane structure in metabolic syndrome has not been fully investigated. The aim of our study was to determine the relationship between structural parameters of the erythrocyte membrane and blood pressure, indices of obesity, plasma lipids, and glucose levels in female patients with metabolic syndrome. MATERIAL/METHODS: In 23 women with ...

OBJECTIVES: Several studies have indicated that the use of the 24-h mean of blood pressure, mainly using reference thresholds derived from the general non-pregnancy practice, does not provide a proper test for diagnosis of hypertension in pregnancy. This prospective study examines previously derived reference thresholds for the 24-h, diurnal, and ...

OBJECTIVE: The purpose of this study was to evaluate the levels of amino-terminal probrain natriuretic peptide (Nt pro-BNP) in preeclampsia in comparison with normotensive pregnancy. MATERIALS AND METHODS: Women with preeclampsia (proteinuria > or = 300 mg/24 h and at least two readings of systolic blood pressure > or = ...
Elvan-TaƟpinar Ayten - - 2005
OBJECTIVE: The epidemiology of pre-eclampsia suggests a constitutional component for the disorder. We have recently shown an association for blood pressure (BP) with stiffness of joints and skin in adolescents, suggesting that constitutionally determined stiffness of body tissues is associated with blood pressure. Therefore, we compared stiffness of the arterial ...
Riskin-Mashiah Shlomit - - 2005
OBJECTIVE: We have previously shown that normotensive pregnant women who later develop preeclampsia demonstrate lower baseline pulsatility index (PI) and resistance index (RI) but normal vasodilatory responses to stimulation tests. In the current study, we tested the hypothesis that women with chronic hypertension who later developed superimposed preeclampsia behave similarly. ...

We developed an asymmetric double logistic curve-fitting procedure for circadian analysis that can determine the rate of change in variables during the day-to-night separately from the night-to-day transition for use in animal studies. We now have applied this procedure to 24-h systolic (SAP) and diastolic arterial pressure (DAP) and heart ...

OBJECTIVE: To estimate if women with preeclampsia had measurable differences in the brachial artery waveforms after blood flow occlusion. METHODS: In a cross-sectional study, 14 preeclamptic and 28 matched normotensive women were assessed. Hemolysis, elevated liver enzymes, low platelets syndrome patients were excluded. All patients had baseline brachial Doppler flow ...

The aim of this study was to determine the normality or otherwise of neurohormone indices, particularly the sympathetic nervous system, in pre-eclamptic patients and document whether changes in body posture magnify any differences between pre-eclamptic and normal women. We studied 11 women with pre-eclampsia and compared them with 17 matched ...
Russell Louise B - - 2004
BACKGROUND: The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recently released new clinical practice guidelines that target systolic blood pressure and identify persons with "prehypertension" (systolic blood pressure, 120-139 mm Hg), previously considered normal, as being at elevated risk and in need of intervention. ...

Systolic and diastolic blood pressures have been inversely related to cognitive performance in prospective and cross-sectional studies. However, in large, community-based samples, these findings have been limited to older adults. In this 20-year longitudinal study, we examined the relationship between baseline blood pressure and cognitive decline for 529 participants using ...
