Cardiologist

You protect the most vital organ in the human body – and Africa's heart health crisis is growing fast.

What this life looks like

The heart never stops working – and as a Cardiologist, neither do you. You specialise in the diagnosis and treatment of heart disease, from rhythm disorders to heart failure to congenital heart defects present from birth. Cardiology sits at the intersection of medicine and technology: you use echocardiograms, electrocardiograms, catheterisation laboratories, and increasingly artificial intelligence to understand what is happening inside a patient's heart and how to fix it. For decades, heart disease was considered a condition of wealthy nations. That picture has changed dramatically. Non-communicable diseases including heart disease are now the fastest-growing cause of death across Africa, driven by urbanisation, changing diets, uncontrolled hypertension, and rising rates of diabetes. Africa is building its cardiology capacity urgently – and the women who train in this specialty now will be among the pioneers of cardiac care on the continent.

What she actually does

A Cardiologist diagnoses and treats conditions including hypertension, coronary artery disease, heart failure, arrhythmias, valvular heart disease, and congenital heart conditions. Interventional cardiologists perform catheter-based procedures such as stenting and balloon valvuloplasty. Electrophysiologists manage heart rhythm disorders. Cardiologists interpret ECGs and echocardiograms, manage cardiac medications, and work closely with cardiac surgeons for patients who need surgery.

Why it matters in Africa

Hypertension affects an estimated 130 million adults in Africa – and the majority are undiagnosed and untreated, leaving them vulnerable to stroke, heart attack, and heart failure. Rheumatic heart disease, a condition that follows untreated strep throat infections, is disproportionately common in Africa and destroys heart valves in children and young adults. Africa has some of the lowest rates of cardiac specialist care in the world relative to need. Training as a cardiologist in Africa means practising at the frontier of medicine, where the need is greatest.

Your pathway in

Biology, Chemistry, Physics, and Mathematics at secondary school. Then an MBBS or MBChB over five to six years, followed by housemanship. You then complete an Internal Medicine residency before applying for Cardiology subspecialty fellowship. The full training pathway from secondary school to practising cardiologist typically takes 12 to 15 years. The West African College of Physicians, the College of Physicians of South Africa, and similar bodies across the continent offer the fellowship qualifications needed.

Skills you will need

Technical: ECG interpretation, echocardiography, cardiac catheterisation for interventional cardiologists, heart failure management, antiarrhythmic pharmacology, and haemodynamic monitoring. Human: The ability to explain complex and frightening diagnoses clearly to patients, composure in cardiac emergencies, precision under pressure, and the ability to manage patients with chronic life-limiting conditions with compassion over the long term. Digital tools: ECG and echocardiography systems, cardiac monitoring equipment, catheterisation laboratory technology, and digital health platforms for remote cardiac monitoring.

A woman in this field

Dr. Karen Sliwa

South Africa

South African cardiologist, Professor at the University of Cape Town, and Director of the Hatter Institute for Cardiovascular Research in Africa. She is one of Africa's most published cardiovascular researchers, with pioneering work on heart disease in pregnancy, rheumatic heart disease, and cardiovascular disease in women in Africa. She has received numerous international awards for her research and is a Fellow of the European Society of Cardiology.

Take your first step

Physics and Mathematics matter as much as Biology for cardiology – the heart is an electrical and mechanical pump and understanding it deeply requires physical and mathematical thinking. Start building comfort with these subjects alongside Biology. Look up the Pan-African Society of Cardiology which has resources on cardiovascular disease across the continent. If you have access to a hospital, ask about cardiology outpatient days when you might observe. Search for videos of echocardiograms and ECG interpretation online – seeing the technology that cardiologists use will give you a concrete sense of the work.
