Dr. Nonhlanhla Mthembu

Nonhlanhla Mthembu is a South African cardiovascular researcher whose work centers on hypertension, arterial hemodynamics, and cardiac remodeling in populations of African ancestry. Affiliated with the University of the Witwatersrand, her research contributes to a leading body of work examining flow-dependent mechanisms of primary hypertension and their clinical implications.

Her publications explore the interplay between systemic flow, aortic stiffness, wave reflections, and left ventricular structure and function. A recurring focus is the role of atrial natriuretic peptide and renal mechanisms in volume-dependent hypertension, highlighting how neurohormonal and hemodynamic factors shape cardiac remodeling and blood pressure control.

Mthembu’s scholarship is distinguished by detailed physiologic phenotyping using echocardiography and central pressure analysis in community-based cohorts. Her contributions advance understanding of heart rate effects, backward wave pressures, and heritable determinants of aortic flow, informing more precise therapeutic targets for hypertension in African settings.
