Optimising a Digital Diagnostic Pathway for Heart Failure in the Community

This is a prospective, observational study. The primary aim is to assess the diagnostic accuracy of Artificial Intelligence (AI) analysis of Point of Care (POC) handheld transthoracic echocardiogram images (POC handheld echocardiogram) compared to the current gold-standard of transthoracic echocardiogram images acquired and analysed by a British Society of Echocardiography (BSE) accredited operator, using a standard echocardiogram machine (standard TTE), for the diagnosis of Heart Failure with reduced Ejection Fraction (HFrEF), in patients referred from the community for investigation of suspected new Heart Failure (HF).
