Cardiac amyloidosis is a condition where the heart muscle, amongst other tissues, is infiltrated by the abnormal build-up of proteins called amyloid. This stiffens and thickens the heart muscle over time which makes it less efficient and puts further stress and strain on the other chambers of the heart, leading to heart failure. The commonest form, that affects predominantly the elderly, is called 'wild-type' ATTR amyloid (TTR is the protein that accumulates). In this condition a patient has a 60% chance of admission to hospital each year after diagnosis. There is no current treatment for ATTR amyloid other than using water tablets to reduce excess fluid and prevent more serious fluid build up in lungs and other tissues. Increasing body weight is the most reliable clinical sign of this fluid build up.
Tele-monitoring is the practice of monitoring patients from a distance and has been shown to reduce heart failure admissions and death in patients with heart failure from any cause. Due to reduced access to primary and secondary care during COVID-19 the investigators instigated tele-monitoring of heart failure in ATTR amyloid patients. This appeared to be an effective intervention in the pilot study. The investigators propose to monitor the weight of patients with cardiac amyloidosis at home and intervene where a build up of fluid is observed by telephone discussion with a doctor. The investigators propose to evidence this in a prospective clinical trial. The investigators will evaluate the effect fairly by comparing tele-monitoring with usual care.

Richmond Research Institute (RRI) is applying existing and new COVID-19 PCR and antibody tests to help develop methodologies which provide fast and accurate results. Infection with coronavirus (SARS-CoV-2) is currently a worldwide pandemic and reliable testing for COVID-19 is crucial to understand who is infected and therefore a risk to others by spreading the infection. RRI are currently carrying out the following tests:
A. Using a membrane-based immunoassay to detect IgG and IgM antibodies to SARS-CoV-2 in whole blood, serum or plasma specimens helps to assess whether an individual has previously had the virus and is potentially immune
B. Polymerase Chain Reaction (PCR) testing using an established method to check for active SARS-CoV-2 infections.
C. Quantification of anti-SARS-CoV-2 IgG and IgM antibodies in whole blood samples.
The above tests are being used by RRI to follow infections (PCR) and immunity (IgG) in their workforce, as well as their families (including children) and visitors to their site.
Collecting this data allows the gathering of epidemiological data on SARS-CoV-2 including incidence, prevalence, information on asymptomatic carriers and efficacy of vaccination. Furthermore, identifying individuals that are infected with SARS-CoV-2 has great potential to improve health outcomes by allowing infected individuals to seek the correct medical treatment as well as self-isolate and reduce transmission.
