Researchers say earlier screening, greater public awareness and Africa-specific treatment strategies will be critical to reducing the growing burden of kidney disease, heart disease and stroke across the continent. Hypertension is no longer a condition primarily associated with older adults, with growing numbers of young Africans developing high blood pressure and facing an increased risk of kidney disease, heart disease and stroke.

This warning formed the focus of the inaugural lecture delivered by Prof. Lebo Gafane-Matemane from the faculty of health sciences at the North-West University.

In her lecture, titled When biology meets context: RAAS, hypertension and the future of cardiorenal health in Africa, she argued that Africa needs research and treatment approaches tailored to its own populations and healthcare realities rather than relying solely on international models.

“The face of hypertension is changing. We are no longer only seeing it in older people; more young Africans are developing high blood pressure,” said Gafane-Matemane. “Hypertension is preventable and manageable, but only if it is diagnosed early.

“We need to expand community screening, start screening children and young adults, and ensure that those diagnosed receive treatment and keep their blood pressure under control.

“Africa cannot rely on a one-size-fits-all approach to hypertension. We need research and treatment strategies that reflect our own populations, disease patterns and healthcare realities.”

The Heart and Stroke Foundation South Africa describes hypertension as one of the leading risk factors for heart disease and stroke, accounting for 13% of deaths globally.

In South Africa, more than one in three adults lives with high blood pressure, while the condition contributes to one in every two strokes and two in every five heart attacks.

Known as the silent killer, hypertension often develops without symptoms, leaving more than half of affected people unaware they have the condition.

The foundation recommends having blood pressure measured at least once a year, as early diagnosis, healthy lifestyle changes and appropriate medication remain the most effective ways to prevent life-threatening complications.

“As researchers, our goal is not simply to generate knowledge, but to improve people‘s lives,” said Gafane-Matemane.

“We need to translate scientific discoveries into better prevention, earlier diagnosis and precision medicine so that we stop losing young people to a disease that can be prevented and controlled.”
