Alcohol consumption and cardiovascular disease risk in an African population in transition: the prospective urban and rural epidemiology (PURE) study
(Medpharm Publications, 2010)Objective: There is evidence showing a cardioprotective effect of light to moderate alcohol consumption in many populations. Whether alcohol consumption reduces cardiovascular disease (CVD) risk in an African population ... -
Association of alcohol consumption with specific biomarkers: a cross-sectional study in South Africa
(BioMed Central, 2015)Alcohol consumption plays an important role in the health transition associated with urbanization in developing countries. Thus, reliable tools for assessing alcohol intake levels are necessary. We compared two biological ... -
Associations between reactive oxygen species, blood pressure and arterial stiffness in black South Africans: the SABPA study
(Springer Nature, 2012)Many mechanisms, including oxidative stress, contribute to hypertension. This study investigated the possible associations between oxidative stress, blood pressure and arterial stiffness in black South Africans. Ambulatory ... -
Fibrosis and coronary perfusion: a cardiovascular disease risk in an African male cohort: the SABPA study
(Taylor & Francis, 2016)Low-grade inflammation has been correlated with risk factors of cardiovascular diseases (CVD). Whether the pro-inflammatory and thrombotic ratio (fibrosis) may contribute to CVD is not known. We therefore aimed to assess ... -
Hypercoagulation and hyperkinetic blood pressure indicative of physiological loss-of-control despite behavioural control in Africans: the SABPA study
(Taylor & Francis, 2016)Objectives: A dissociation between behavioural (in-control) and physiological parameters (indicating loss-of-control) is associated with cardiovascular risk in defensive coping (DefS) Africans. We evaluated relationships ... -
Hyperpulsatile pressure, systemic inflammation and cardiac stress are associated with cardiac wall remodeling in an African male cohort: the SABPA study
(Nature, 2016)Inflammation may contribute to an increase in cardiac wall stress through pathways related to cardiac remodeling. Cardiac remodeling is characterized by myocyte hypertrophy, myocyte death and modifications of the extracellular ... -
Hypothalamic-pituitary-adrenal-axis dysregulation and double product increases potentiate ischemic heart disease risk in a Black male cohort: the SABPA study
(Springer Nature, 2017)Emotional distress has been associated with a poorer prognosis in myocardial infarction patients. Elevated adrenocorticotrophic hormone (ACTH), lower cortisol, dehydroepiandrosterone sulfate (DHEAS) and cortisol:DHEAS, as ... -
Low testosterone and hyperkinetic blood pressure responses in a cohort of South African men: the SABPA study
(Taylor & Francis, 2013)Hypertension (HT) and the metabolic syndrome are major problems in Africa. The role of sex hormones in the cardiovascular profile of black Africans in South Africa has not been studied. Our objective was to study the ... -
Psychosocial stress but not hypertensive status associated with angiogenesis in Africans
(Taylor & Francis, 2014)Aim. Increased angiogenic factors [vascular endothelial growth factor-A (VEGF-A) and angiopoietin-2 (Ang-2)] have been associated with vascular dysfunction and hypertension. Black Africans undergoing rapid urbanization ... -
Silent ischemia is associated with subclinical atherosclerosis in African males: the sympathetic activity and ambulatory blood pressure in Africans study
(Taylor & Francis, 2012)Silent myocardial ischemia is a predictor of subclinical atherosclerosis driven by increased cardiovascular risk markers, although still unknown in Africans. The aim of this study was to assess if cardiovascular risk markers ...
