The association of measures of the micro- and macro-vasculature with selenium and GPx activity in a young bi-ethnic population: the African-PREDICT study
(Taylor & Francis, 2019)
Objective: Selenium plays an important physiological role as component for antioxidant selenoproteins such as glutathione peroxidase (GPx). Since oxidative stress contributes to hypertension development, it is likely that ...
Blood pressure variability is significantly associated with ECG left ventricular mass in normotensive Africans: the SABPA study
(Nature Publishing Group, 2011)
The prognostic significance of blood pressure (BP) variability has lately enjoyed considerable attention. The need for early markers of cardiovascular dysfunction is imperative in black South Africans who have a significant ...
Comparison of central pressure estimates obtained from SphygmoCor, Omron HEM-9000AI and carotid applanation tonometry
(Lipppincott, Williams & Wilkins, 2011)
Background: The Omron HEM-9000AI is the first automated tonometer to provide an estimate of central SBP (cSBP), which is considered to be more predictive of cardiovascular events than brachial pressure. However, considerable ...
Arterial stiffness, ambulatory blood pressure and low-grade albuminuria in non-diabetic African and caucasian men: the SABPA study
(Nature Publishing Group, 2011)
Recent evidence suggests that low-grade urinary albumin excretion is a marker of early general attenuation of vascular function, but studies are limited to Caucasian population groups. We compared low-grade urinary albumin ...
Associations of cholesterol and glucose with cardiovascular dysfunction in black Africans: the SABPA study
(Informa healthcare, 2011)
The aim was to determine whether blood glucose or cholesterol is the more prominent contributor to cardiovascular dysfunction in 101 African men and 99 African women. We measured ambulatory daytime blood pressure (BP), ...
Aldosterone and renin in relation to surrogate measures of sympathetic activity: the SABPA study
(Clinics Cardive Publishing, 2019)
Introduction: Hypertension, particularly in black populations, is often accompanied by augmented sympathetic nervous system activity and suppressed renin activity, indicative of possible blood pressure (BP) dysregulation. ...
Facilitated defensive coping, silent ischaemia and ECG left-ventricular hypertrophy: the SABPA study
(Kluwer, 2012)
Background: Defensive active coping responses (being-in-control, acceptance of the stressor as reality) have been associated with vascular hyper-responsiveness in urban Africans. However, the association between active ...
Sex hormones associated with subclinical kidney damage and atherosclerosis in South African men: the SABPA study
(Kluwer, 2012)
Background: Hypertension and increased blood glucose are associated with subclinical kidney damage, atherosclerosis and with low testosterone values. Low testosterone in men is often accompanied by increased levels of ...
The Von Willebrand factor as marker of vascular function in South African women
(Oxford Univ Press, 2008)
BACKGROUND:
The increasing prevalence of hypertension and vascular-related morbidity and mortality among Africans emphasizes the need to identify markers for the early detection of vascular disease. Caucasian-based ...
The Association of Red Blood Cell Counts with Endothelin-1 in African and Caucasian Women
(Informa Healthcare, 2009)
The literature shows an increase in endothelin-1 with increased levels of erythrocytes. There are also indications that inflammation and elevated endothelin-1 levels interact with erythropoiesis. In this study, the association ...
