Autonomic activity and leptin in Africans and whites: the SABPA study
(Wolters Kluwer/Lippincott, Williams & Wilkins, 2014)Objectives: Evidence exists that leptin enhances sympathetic activity and may thereby contribute to the development of obesity-related hypertension. Sympathetic activation also seems more prominent in Africans than whites. ... -
Blood glutathione and subclinical atherosclerosis in African men: the SABPA study
(Oxford Univ Press, 2009)Background: Sub-Saharan Africans face an increasing burden of hypertension and related cardiac and cerebrovascular morbidity and mortality, making the identification of factors leading to early vascular abnormalities ... -
Cardiovascular risk stratification and blood pressure variability on ambulatory and home blood pressure measurement
(Current Medicine Group, 2014)Abstract Variability is a phenomenon attributed to most biological processes and is a particular feature of blood pressure (BP) that concerns many physicians regarding the clinical meaning and the impact on their clinical ... -
Double product reflects the predictive power of systolic pressure in the general population: evidence from 9,937 participants
(Oxford University Press, 2013)BACKGROUND The double product (DP), consisting of the systolic blood pressure (SBP) multiplied by the pulse rate (PR), is an index of myocardial oxygen consumption, but its prognostic value in the general population remains ... -
Evaluation of waist-to-height ratio to predict 5 year cardiometabolic risk in sub-Saharan African adults
(Open Access, 2014)Background and aims Simple, low-cost central obesity measures may help identify individuals with increased cardiometabolic disease risk, although it is unclear which measures perform best in African adults. We aimed to: ... -
Exploring the link between cardiovascular reactivity and end–organ damage in African and Caucasian men: the SABPA study
(Oxford University Press, 2013)BACKGROUND Heart failure in the African population is reaching alarming levels. Increased afterload as a result of increased vasoconstriction during stress may lead to impaired ventricular function and stroke volume (SV) ... -
Leisure time physical activity participation in women (30-65 years) with high coronary heart disease risk indicators
(AFAHPER-SD, 2011)The aim of this study was to determine the effect of leisure time physical activity participation (LTPA) on South African women presenting with some enhanced coronary heart disease (CHD) risk indicators (physical inactivity, ... -
The relationship between cortisol, C-reactive protein and hypertension in African and Causcasian women: the POWIRS study
(Clinics Cardive Publishers, 2012)Research on the roles that C-reactive protein (CRP) and other risk factors such as cortisol and obesity play in the diagnosis of cardiovascular disease (CVD) in African and Caucasian women has become increasingly imperative ... -
Retinal vessel calibres and haemostasis in black and white South Africans: the SABPA study
(Lippincott Williams & Wilkins, 2015)Objectives: Retinal arteriolar narrowing associates with hypertension development and indicates increased cardiovascular risk. Evidence on whether the retinal vessel "calibres are related to the haemostatic system is ... -
Revisiting the relationship between blood pressure and insulin-like growth factor-1
(American Heart Association, 2014)Conflicting evidence exists on the relationship between blood pressure (BP) and insulin-like growth factor-1 (IGF-1). We reviewed available articles and pooled extrapolated regression coefficients for the association between ...
