AimsA lower heart rate (HR) increases central blood pressure through enhanced backward wave pressures (Pb). We aimed to determine whether these relationships are modified by increases in aortic stiffness.MethodsUsing non-invasive central pressure, ao

Associations between circulating resistin concentrations and left ventricular mass are not accounted for by effects on aortic stiffness or renal dysfunction

Autor: Glenda Norman, Gavin R. Norton, Vernice Peterson, Monica Gomes, Carlos D. Libhaber, Pinhas Sareli, Angela J. Woodiwiss

Publikováno v: BMC Cardiovascular Disorders, Vol 20, Iss 1, Pp 1-9 (2020)

Abstract Background Although, in-part through an impact on left ventricular mass (LVM), resistin (an adipokine) may contribute to heart failure, whether this is explained by the adverse effects of resistin on aortic stiffness and renal function is un

The relationship between the nitric oxide synthase gene and the risk of hypertension defined according to ambulatory blood pressures

Autor: Geoffrey Candy, Danelle Badenhorst, Elena Libhaber, Pinhas Sareli, Gavin R. Norton, Richard Brooksbank, Angela J. Woodiwiss

Publikováno v: SA Heart Journal, Vol 6, Iss 3, Pp 148-153 (2017)

Although nitric oxide (NO) plays an important role in blood pressure (BP) control, whether variation of genes involved in regulating the synthesis of NO influences BP is uncertain. As the heritability of BP is stronger for ambulatory than it is for c

Limited contribution of insulin resistance and metabolic parameters to obesity-associated increases in ambulatory blood pressure in a black African community

Autor: Adamu J. Bamaiyi, Gavin R. Norton, Glenda Norman, Olebogeng HI. Majane, Pinhas Sareli, Angela J. Woodiwiss

Publikováno v: International Journal of Cardiology. Hypertension, Vol 2, Iss , Pp 100010- (2019)

Although accounting for a striking proportion of obesity effects on blood pressure (BP) in other populations, the extent to which obesity-associated increases in BP are explained by insulin resistance and metabolic changes in populations of African a

Contribution of Increases in Late Systolic Ejection Volume to the Impact of Heart Rate on Central Arterial Pulse Pressure in a Community Sample

Publikováno v: American Journal of Hypertension. 35:989-997

BACKGROUND A lower heart rate (HR) increases left ventricular (LV) ejection volume. Whether this contributes to the adverse effects of HR on central pulse pressure (PPc) through reservoir volume effects is uncertain. METHODS Using noninvasive central

Attenuated Relationships Between Indexes of Volume Overload and Atrial Natriuretic Peptide in Uncontrolled, Sustained Volume-Dependent Primary Hypertension

Publikováno v: Hypertension (Dallas, Tex. : 1979). 80(1)

Background: Whether systolic blood pressure (SBP) control in sustained volume-dependent primary hypertension is associated with blunted ANP (atrial natriuretic peptide) relationships with indexes of volume load is unknown. Methods: Systemic hemodynam

Independent relationships between renal mechanisms and systemic flow, but not resistance to flow in primary hypertension in Africa

Publikováno v: Journal of Hypertension. 39:2446-2454

AIMS Whether renal mechanisms of hypertension primarily translate into increases in systemic vascular resistance (SVR) in all populations is uncertain. We determined whether renal mechanisms associate with either increases in SVR (and impedance to fl
