Thanks for the article ddwn. It’s a good read but perhaps not surprising that the authors have the view more research is required in this field after reading the declaration of competing interests.

The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Authors PVJ, ANR, JHT, and CJP are members of the Executive Steering Committee for the CardiAMP Heart Failure Trial and have received consultancy fees and/or grant support for their activities from BioCardia, Inc., the trial sponsor.
