Epidemiology and Pathophysiology of Acquired Heart Failures Amenable to Surgical Interventions in the Sub-Saharan Africa
Abstract
Heart failure (HF) is an important cause of morbidity and mortality in sub-Saharan Africa and indeed
worldwide. The management of this condition has largely been thought to be within the domain
of the Physician with the Surgeon having little or no role to play. The commonest cause of HF
that may require surgical intervention is rheumatic valvular heart disease especially in the young
age group while ischaemic heart disease still remains at the low rung of the ladder and interestingly,
hypertrophic cardiomyopathy is becoming common. Most of the literatures reviewed failed
to identify pericardial diseases, though it ranked topmost in the face of tuberculosis and HIV infections
in the sub-region, and the other non-cardiac structures as important causes of HF which is
amenable to surgical intervention. Equally, what have not been clearly identified are the surgical
aspects; indeed its sub-classifications into heart and non-heart causes have hitherto not been documented.
Even though these lists from this review are not exhaustive of the numerous unidentified
causes of surgical HF, this would act as stimulus for further and extensive documentation of
guideline for the recognition of these sub-classifications of HF amenable to surgery.
