ABSTRACT Objective: to develop an ICNP® terminology subset for the care of people with heart failure. Methods: this is a methodological study, which used the theoretical framework of the Mid-Range Nursing Theory for Cardiovascular Rehabilitation, with the steps: Construction of nursing diagnoses/outcomes and interventions statements and Cross-mapping of statements constructed. Results: forty-two diagnosis/outcome statements and 179 nursing intervention statements were constructed, organized based on five theory concepts, with a higher prevalence of statements related to “Rehabilitative care”, “Psychosocial support for patients and families” and “Supervised cardiovascular rehabilitation program”. Final considerations: it was possible to build nursing diagnosis/outcome and intervention statements for developing a terminology subset for the care of people with heart failure, based on the chosen theory.
