South Africa: SA's Heart Health Crisis Demands a Public Health Response

South Africa faces a critical heart health crisis, with the heart and stroke foundation reporting that approximately 225 lives are lost daily due to heart disease or stroke. These conditions account for nearly one in six deaths in the country, and more than half of cardiovascular fatalities occur before the age of 65. The World Heart Federation urges people to "Don't Miss a Beat" by recognizing early warning signs, protecting their hearts, and demanding action.

High blood pressure, or hypertension, is a significant contributor to this crisis, causing one in two strokes and two in five heart attacks. Often referred to as the "silent killer," hypertension remains undetected until it strikes, as it has no visible symptoms. An analysis of blood pressure screening campaigns conducted across South Africa between 2017 and 2021 revealed that nearly 30% of participants had hypertension.

However, only 54% of them were aware of their condition, 47% were receiving treatment, and around a quarter of those on treatment still did not have their blood pressure under control.

Awareness of high blood pressure among adults under 65 is particularly concerning, with just 24% of this age group aware of their hypertension status. Public health researchers emphasize the crucial role they play in generating evidence to support the development of effective health policies, systems, and reforms in South Africa.

As World Heart Day approaches on September 29th, the World Heart Federation calls for increased attention to this pressing issue, emphasizing the need for better screening, early intervention, and access to affordable prevention measures.
