Heart failure (broad - for excluding people) SNOMED CT
List of all codes related to heart failure, to exclude people with previous history or evidence of heart failure. This includes not only diagnoses, but heart failure-related medication reviews or management plans.

This list is meant to be very broad, and is not to be used to identify new diagnoses.
Published by REDUCEHF
Heart failure (secondary care) ICD-10
Codelist to identify new diagnoses of heart failure in secondary care (admitted patient care data).

JJL - I tried a few search terms to no benefit. I have included acute on chronic, as it is the diagnostic event, not new pathology that we are trying to identify. I excluded foetal/neonatal as this study is of adults.
