Introduction Epidemiology of Hypertension Throughout the world, 1 in every 4 adults suffers from hypertension,1 a disease that contributes to 49% of ischemic heart disease and 62% of strokes worldwide. Inadequately controlled hypertension is currently the number one attributable risk for death across the globe.2 Data from the Framingham Heart Study predict(More)
The genetic contribution to performance on scales designed to measure mild to moderate decrements in cognitive functioning in a population at risk is unknown. In the present analysis, 134 monozygotic and 133 dizygotic male twin pairs (mean age, 63 years) were given three cognitive tests: the Mini-Mental State examination, the Iowa Screening Battery for(More)
Blood pressure and heart rate were recorded at 15-min intervals for 24 hr in 60 untreated patients with uncomplicated mild essential hypertension using a new automatic noninvasive portable recorder. During the recording, the patients went about their normal daily routine, of which they kept a detailed record. The data were analyzed for five different(More)
Twenty-one percent of 292 patients with untreated borderline hypertension (clinic diastolic blood pressures persistently between 90 and 104 mm Hg) were found to have normal daytime ambulatory pressures (defined from a population of normotensive subjects). These patients were defined as having "white coat" hypertension, and they were more likely to be female(More)
OBJECTIVE There is emerging evidence from animal studies suggesting a key role for methylation in the pathogenesis of essential hypertension. However, to date, very few studies have investigated the role of methylation in the development of human hypertension, and none has taken a genome-wide approach. Based on the recent studies that highlight the(More)
BACKGROUND Despite evidence linking obesity to impaired immune function, little is known about the specific mechanisms. Because of emerging evidence that immune responses are epigenetically regulated, we hypothesized that DNA methylation changes are involved in obesity induced immune dysfunction and aimed to identify these changes. METHOD We conducted a(More)
The influence of Na+ excretion and race on casual blood pressure and ambulatory blood pressure patterns was examined in a biracial sample of healthy, normotensive children and adolescents (10-18 years; n = 140). The slopes relating 24-hour urinary Na+ excretion to systolic blood pressure were different for both black and white subjects for casual blood(More)
BACKGROUND Cardiovascular structure and function in youth with prehypertension have been incompletely investigated. METHODS Casual and ambulatory blood pressure (BP) measurement, arterial stiffness, noninvasive hemodynamic profiles, and cardiac structure were studied in a twin cohort of American black and white youth (n = 942; mean age, 17.6 +/- 3.3 years(More)
This study was undertaken to examine whether blood pressure reactivity measured in the controlled setting of a laboratory could be correlated with blood pressure changes occurring during daily life. The subjects were 164 untreated hypertensives with mild hypertension, all of whom had a 24-hour ambulatory blood pressure recording, during which their(More)
