Dr. Elijah Njau, a Consultant Cardiologist at Heartlink Cardio Centre, is deeply concerned about the shift in Africa’s health picture. “While infectious diseases such as malaria, HIV, pneumonia, and tuberculosis are still part of everyday hospital life, doctors are now seeing more and more patients with cardiovascular problems. Heart failure in Africa, particularly, is taking up a bigger share of hospital beds and health resources than ever before“. On World Heart Day, it is crucial to acknowledge the growing impact of heart failure in Africa.
At Heartlink Cardio Centre, Dr. Njau says the trend is clear. “Heart failure is no longer rare in our hospitals. It accounts for roughly 3 to 7 percent of all admissions in Sub-Saharan Africa and nearly a third of heart-related cases,” he explains. Heart failure across Africa poses a significant challenge. He adds that the numbers may be even higher since many countries don’t have strong reporting systems for tracking cases. World Heart Day presents a fitting opportunity to reflect on this challenge of heart failure across the continent.
The Kenya Cardiac Society has also raised concern over this growing burden, noting that hypertension and related heart complications are now among the leading causes of hospitalization in Kenya. Globally, the World Heart Federation continues to emphasize that cardiovascular disease remains the number one cause of death worldwide, making Africa’s rising tide of heart failure a critical challenge. Awareness of heart failure in Africa is essential to drive change. Heart failure in Africa -World Heart Day, highlights the worldwide need for increased awareness and improved healthcare measures.
One of the most worrying differences compared to the developed world is the early age of onset. “Here, people often develop heart failure in their early forties or fifties,” Dr. Njau says. The issue of heart failure in Africa often arises earlier than expected. “In high-income countries, you’d expect to see it mostly in the older population.” The key drivers, he points out, are poorly controlled blood pressure, obesity, diabetes mellitus, and the long-lasting damage of rheumatic heart disease. Observing World Heart Day, Dr. Njau calls for heightened awareness.
Hypertension stands out as the biggest culprit. Almost one in three adults across the region has high blood pressure, yet many don’t know it. “Because it often has no symptoms, people go about their lives until the damage is already done. That’s when you see strokes, kidney disease, or full-blown heart failure,” Dr. Njau sadly notes, reminding us of the heart failure issue prevalent in Africa.
The consequences are harsh. In some hospitals, nearly one in ten patients admitted with heart failure dies during their stay in hospital. Within a year of that first hospitalization, as many as one in five patients may not survive. Addressing heart failure in Africa requires a concerted effort. Delayed diagnosis, poor access to medicines, and poor follow-up care all play a role in these dismal outcomes. On World Heart Day, it is crucial to spotlight heart failure in Africa and strive to improve these statistics.
Dr. Njau highlighted hypertension, diabetes, high cholesterol, and the early signs of heart disease often develop silently, showing no symptoms in the initial stages. The spread of heart failure across Africa raises significant concerns. Millions of people remain undiagnosed until a heart attack, stroke, or sudden complication occurs. This growing prevalence of heart failure in Africa is why routine screening is critical, even for those who feel healthy. “Many people don’t realize they are at risk until it’s too late. A simple blood pressure check, blood sugar check, cholesterol test, or ECG can detect issues early enough for effective preventive intervention.”
Even so, Dr. Njau strongly believes that the situation can be turned around. “The best defense is prevention,” he says. The challenge of heart failure in Africa should not be underestimated. “Routine checks for blood pressure, blood sugar, and cholesterol, even for people who feel perfectly healthy, can save lives. And if people know the warning signs, like breathlessness, chest pain or swollen feet, they can get help before it’s too late.” He stresses that stronger community health systems, accessible and affordable treatment, and consistent follow-up are the vital keys to easing Africa’s and Kenya’s growing burden of heart failure.
This commitment aligns with the ongoing calls from the Kenya Cardiac Society for stronger local interventions and the World Heart Federation’s global push for preventive care and awareness. At Heartlink Cardio Centre, we stand in step with these priorities, determined to play our role in protecting hearts and saving lives. Our mission to combat heart failure in Africa remains unwavering.
