Is Chorea a Cause of RHD?


What is the link between chorea and RHD?


The connection of chorea and rheumatic heart disease (RHD) is linked by rheumatic fever (RF). RF is the major cause of RHD and chorea is a major and neurologic and major manifestation of RF. The chorea is also known as Sydenham chorea, rheumatic chorea or Saint Vitus dance.

Sydenham chorea is the result of childhood infection with Group A beta-haemolytic Streptococcus. It is reported that 20-40% of patients with RF develop Sydenham chorea. Besides, it is a kind of disease that stays latent, which usually occurs up to 6 months after the acute infection. However, once developing the disease, patients may occasionally have it as the presenting symptom of RF.

Sydenham chorea is rare in the developed world, but there are still a great number of cases in the poor setting. It occurs more in females rather than males and in children rather than adults. Although adults can also have the disease, they usually had such infection in their childhood.
