Clinical Trial Summary

It is hypothesised that the MyoVista wavECG has the potential to show non inferior sensitivity and specificity compared to the current heart failure pathway screening tools of BNP/NT-proBNP and 12 lead resting ECG, but has the advantage of providing a single, familiar, inexpensive point of care test which provides point of care results and can act as a prescreen, or in circumstances replacement to BNP/NTpro-BNP testing, and eliminate a proportion of the unnecessary testing and echo referrals. A comparative performance analysis of the modalities will form the basis for the study with subsequent reporting on the financial impact and societal benefits of any potential pathway change.


Clinical Trial Description

This is a multi-center, non-interventional, single arm, non-inferiority clinical study of the MyoVista wavECG ability to identify primary care patients for referral to secondary care for diagnosis of heart failure (as defined by BSE (British Society of Echocardiography) guidelines for echo), in direct comparison to BNP/NT-proBNP. The study will be conducted at a maximum of 10 investigational secondary care sites within the United Kingdom, and some/all referring primary care centres for each site. Study subjects presenting at primary care with shortness of breath, risk factors for and/or suspicion of heart failure will be referred to secondary care for 2D transthoracic echocardiogram based on borderline and abnormal BNP/NT-proBNP results as part of the current heart failure pathway as defined by the NICE (National Institute for Health and Care Excellence) guidelines, with the MyoVista wavECG used for the conventional 12 lead ECG reporting and comparison purposes only. MyoVista wavECG results will not be used in the diagnosis of a patient, and/or for the basis of a patient referral to echocardiography for the study duration. In commercial use the MyoVista wavECG will be intended for use in a population of patients being considered for such a referral by providing CWT (Continuous Wavelet Transform) and AI (Artificial Intelligence) derived informatics surrounding an overall summary of left ventricular relaxation abnormalities (High Negative, Negative, Borderline, Positive and Highly Positive). The design of this study will allow for an appropriate evaluation of safety and effectiveness for that population. The study duration will consist of a single visit for all study subjects, after which the subject's participation in the trial will conclude unless longitudinal study inclusion criteria met and agreed at enrollment (Normal BNP/NT-proBNP, MyoVista wavECG result Negative, Borderline, Positive, Highly Positive). All study subjects will provide written informed consent for the procedures consistent with the study protocol. ;
