Improvements in the detection of FD, together with more organised clinical services for rare diseases, has led to a rapid growth in the disease prevalence. Earlier and more frequent diagnosis of asymptomatic individuals before development of the disease itself has focused attention on early detection of organ involvement and closer monitoring of disease progression. Moreover, the introduction of enzyme replacement therapy within the last two decades has changed the natural history of FD as follows: a) increased life expectancy; b) improved morbidity; c) modification of the main cause of morbidity and mortality from renal (kidney) to cardiovascular (heart) events, including heart failure, abnormal heart rhythms, stroke and sudden death. Although symptoms such as palpitations and blackouts are extremely common, information on the frequency of proven abnormal heart rhythms is limited. In addition, the rate and appropriateness of implantation of life-saving devices is very variable, including pacemakers to boost the heart when too slow and cardio-defibrillators that stop the heart when too fast. The main markers of risk in similar diseases such as hypertrophic cardiomyopathy cannot be used in FD. While patients are routinely followed up in clinic with heart tracings and echocardiography (ultrasound of the heart), a recent small study has emphasised that these tests under-estimate the burden of abnormal heart rhythms in patients with advanced FD. The use of continuous heart monitoring with an implantable loop recorder (ILR) has led to a significant change in treatment in 13 out of 15 of FD patients. The investigators believe that more frequent use of ILRs will identify a greater need for change in therapy in many more patients than currently treated, with the aim of reducing morbidity and mortality in this patient cohort. In addition this will provide valuable data to inform an estimate of future risk for these patients.", 'detailedDescription': 'This is a 3-year open-label multicentre randomised controlled trial assessing arrhythmia burden in patients with Fabry cardiac disease.
