Effects of acute and chronic stress on the L-arginine nitric oxide pathway in black and white South Africans: the sympathetic activity and ambulatory blood pressure in Africans study
(Lippincott, Williams & Wilkins, 2013)
OBJECTIVE:
This study investigated the impact of stress on effectors of the L-arginine/nitric oxide (NO) system including the endogenous inhibitor asymmetric dimethylarginine (ADMA).
METHODS:
Black (n = 168) and white ...
Cohort profile: sympathetic activity and ambulatory blood pressure in Africans (SABPA) prospective cohort study
(Oxford Univ Press, 2015)
Adapting to an over–demanding stressful urban environment may exhaust the psychophysiological resources to cope with these demands, and lead to sympathetic nervous system dysfunction. The evidence that an urban–dwelling ...
Greater cardiovascular reactivity to a cold stimulus is due to higher cold pain perception in black Africans: the sympathetic activity and ambulatory blood pressure in Africans (SABPA) study
(Kluwer, 2012)
Objective: To evaluate the role of pain perception and pain stimulus components for blood pressure responses to stress in the black and the white African population with hypertension.
Basic methods: Cardiovascular regulation ...
Depressive symptoms and sub-clinical atherosclerosis in Africans: role of metabolic syndrome, inflammation and sympathoadrenal function
(Elsevier, 2011)
Depressive symptoms have been consistently associated with sub-clinical atherosclerosis and future risk of coronary heart disease events. However, the pathways linking depression and coronary atherosclerosis are poorly ...
Chronic defensiveness and neuroendocrine dysfunction reflect a novel cardiac troponin T cut point: the SABPA study
(Elsevier, 2017)
Background
Sympatho-adrenal responses are activated as an innate defense coping (DefS) mechanism during emotional stress. Whether these sympatho-adrenal responses drive cardiac troponin T (cTnT) increases are unknown. ...
