People with heart failure often have repeated stays in hospital when symptoms of breathlessness and heart palpitations worsen, and they need their mediation adjusted. They frequently experience deteriorating symptoms for some time before seeking help. This means their care is reactive and delayed. We propose to utilise a new novel technology of pressure monitoring within the major artery from the heart to the lungs to allow proactive care. This will enable monitoring of people in their own homes and adjustment of drugs remotely. The technology involves the placement of a very tiny pressure sensor within the pulmonary artery. The pressure signals can be read remotely. This is a radical change in care but one we propose will initiate treatment early, reduce stays in hospital and provide overall better outcomes.
