Fabry Disease (FD) has been a diagnostic challenge since it was first recognised in 1898, with patients traditionally suffering from considerable delay before a diagnosis is made. Cardiac involvement is the current leading cause of death in FD. A combination of improved enzyme assays, availability of genetic profiling, together with more organised clinical services for rare diseases, has led to a rapid growth in the prevalence of FD. The earlier and more frequent diagnosis of asymptomatic individuals before development of the phenotype has focussed attention on early detection of organ involvement and closer monitoring of disease progression. The high cost of enzyme replacement therapy at a time of constraint within many health economies moreover, has challenged clinicians to target treatment effectively. This article provides an outline of FD for the general physician and summarises the aetiology and pathology of FD, the cardiovascular (CV) consequences thereof, modalities used in diagnosis, and then discusses current indications for treatment, including pharmacotherapy and device implantation
