The rates of high blood pressure among African Americans, as a group, are the highest in the world. The implications for higher average blood pressure include complications for many major chronic conditions, such as cardiovascular disease and diabetes. Less well studied is the effect of blood pressure on the cognitive ...

It has been suggested that, in late gadolinium enhancement, the signal of right ventricular myocardium is nulled at a shorter inversion time than the left. While we initially made the same observation, we believe that the difference is not real, but results from artifacts. We present 7 cases as well ...

African Americans as a group have higher blood pressure than individuals of northern European ancestry (non-Hispanic Whites). We investigate whether psychosocial factors explain the resting blood pressure of healthy, community-dwelling African Americans in our study. A convenience sample of self-reported normotensive African Americans aged 18-65 years who live in the ...

The alpha(2)-adrenoceptor agonist clonidine reduces blood pressure more effectively in White than Black Americans despite similar degrees of sympatholysis. Functional genetic variation in receptor signaling mechanisms, for example in the beta 3 G-protein subunit (GNB3 C825T) and in the alpha(2C)-adrenoceptor subtype (ADRA2C del322-325), may affect drug responses. We examined the ...

BACKGROUND: The adverse association between blood pressure and carotid artery intima-media thickness (IMT), a surrogate measure of subclinical atherosclerosis, is well-known. However, whether the G-6A polymorphism of the angiotensinogen (AGT) gene, a candidate gene of hypertension and vascular remodeling, modulates this relationship is unknown. METHODS: In 662 white and black ...

Historically, blood pressure control in Hispanics has been considerably less than that of non-Hispanic whites and blacks. We compared determinants of blood pressure control among Hispanic white, Hispanic black, non-Hispanic white, and non-Hispanic black participants (N=32 642) during follow-up in a randomized, practice-based, active-controlled trial. Hispanic blacks and whites represented ...

Examination of concealed writing is often a challenge for forensic document examiners. Although the published literature describes many techniques, these are often only successful when the writing has been concealed by pencil, pen, or by spreading inks of different tint or by smearing of the writing with colored fluids. When ...

Recently, the existence of so-called masked hypertension has attracted attention. In this study, the reproducibility of masked hypertension determined from morning and evening home blood pressure measurements was examined over a 6-month period. Home blood pressure measurements were taken consecutively for 7 days in volunteers at a company in 2002 ...

BACKGROUND: On average, angiotensin-converting enzyme inhibitors produce less office blood-pressure lowering in African Americans compared with Caucasians. Past studies did not compare daytime and nighttime ambulatory blood-pressure responses to angiotensin-converting enzyme inhibitors in African Americans and Caucasians. METHODS: We measured the office and ambulatory blood-pressure response to 8 weeks of ...

Prior investigations have shown impaired endothelial function in hypertensive blacks when compared with whites. It is not clear, however, whether the difference in vascular responsiveness predates or follows the development of hypertension. Thirty-nine young black adults with a family history of essential hypertension and 41 control participants were studied for ...

Understanding the impact of patient factors on blood pressure (BP) management is an important step to developing interventions to improve cardiovascular health. The National Health and Nutrition Examination Survey (NHANES) 1999-2002 was used to identify predictors of hypertension awareness, treatment, and control. An estimated 63.3 million (31.0%) US adults currently ...

It has been established that childhood cardiovascular (CV) risk factors are predictive of adulthood vascular changes as measured by carotid intima-media thickness (IMT). However, whether this relationship is race- and gender-specific is not known. This aspect was examined in a black-white cohort of 868 adults (29% blacks, 42% males) aged ...

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is a well-recognized clinico-neuroradiological transient condition. Early recognition is of paramount importance for prompt control of blood pressure or removal of precipitating factors and treatment of epileptic seizures or status epilepticus. Delay in the diagnosis and treatment may in fact results in death or ...

BACKGROUND: Racial variations are reported in the natural history of hypertension. For example, hypertension is significantly more prevalent in blacks than whites. Endothelial cells are important regulators of vascular tone and homeostasis, in part through secretions of vasoactive substances including endothelin-1 (ET-1), a small peptide with potent vasopressor actions. In ...
