Cardiovascular Disease

 

The World Health Organisation (WHO) estimates that the cardiovascular disease claims about 17.5 million people every year. Although some cardiovascular diseases are more prevalent than depending on the continent, sub-Saharan Africa still makes up for a significant proportion of these deaths. The continent claims over a staggering 810,000 lives per year or 1 life every 40 seconds! Even more astounding is that most are preventable.

Roll over the each disease to see a description of the cardiovascular disease burden in sub-Saharan Africa.

Sub Sahara Africa Map Rheumatic Heart Valve Disease - 20,000 deaths per year.This is our biggest surgical challenge. Typically after a bacterial sore throat infection and with no antibiotic cover, the patient's heart valve is damaged and over several years gets scarred such that blood cannot flow. The heart struggles and progressively fails. The patient needs a valve replacement. Inflammatory Heart Disease – 42,000 deaths per year .This involves inflammation of the heart (myocarditis) or surrounding tissues for example lining of the heart – pericarditis, by infection or other toxic causes. Hypertensive Heart Disease – 60,000 deaths per year - High blood pressure causes damage to blood vessels and heart which can lead to rupture and ‘furring' up of arteries. Sub-Saharan Africans are particularly prone to hypertension for reasons that are unclear. Ischaemic Heart Disease – 332,000 deaths per year  -  Narrowing of the blood vessels supplying the heart is the biggest killer in the Western World. This is slowly catching up in sub-Saharan Africa with the rapidly changing lifestyle with the Western influence and the rise in smoking. We anticipate this will a growing part of our surgical workload. Cereberovascular Disease – 359,000 deaths per year -  Disease affecting the blood vessels supplying the brain leading to strokes. This is usually related to risk factors for ischaemic and hypertensive heart disease.

The socio-economic impact of cardiovascular disease is astonishing worldwide. In sub-Saharan Africa , the impact is even more pronounced as the major diseases tend to affect the younger working patients. The Earth Institute at Columbia University , New York has estimated that in the developing nations of India , China , Brazil , South Africa and Mexico alone, 21 million future years of productivity are lost every year due to cardiovascular disease [1]. Financially, cardiovascular disease costs even in the Western World much more than infections or cancer combined. In USA , the direct and indirect costs are over €310 billion per year [2]. The situation in South Africa as early as 1991 was similar where cardiovascular disease cost the economy US $750 million. The actual cost was much more as this did not account for rehabilitation and follow up [3].
