Not assessable: your judgement Heart pumping fraction (ejection fraction, EF) Draft · pending review

The note says HFrEF; the echocardiogram report on file states no left-ventricular ejection fraction, so the type cannot be checked.

Evidence from the record (1)

Echocardiogram report 2026-10-13 (transthoracic, right-heart study, report text only): the report text states no left-ventricular ejection fraction (Dr. Ines Varga (cardiology))

Choose wording yourself, or none. Nothing is pre-selected; the list and its order are the same for every patient.

Met / not met only says whether the recorded value falls inside that definition's range. It is not a recommendation; the diagnosis is your judgement.

Needs: latest ejection fraction 40% or lower Record: no ejection fraction on file · ∅ not assessable
Needs: latest ejection fraction 41% to 49% Record: no ejection fraction on file · ∅ not assessable
Needs: latest ejection fraction 50% or higher Record: no ejection fraction on file · ∅ not assessable
Needs: an earlier ejection fraction of 40% or lower, the latest above 40%, and a rise of at least 10 points Record: no ejection fraction on file · ∅ not assessable

One click places the wording you choose in the unsigned draft as a new line at the end of the assessment (your existing wording is not changed), highlighted, for you to edit or undo before signing. Your choice and the evidence shown are recorded.

Clinical implications of the universal definition for the prevention and treatment of heart failure

Clinical implications of the universal definition for the prevention and treatment of heart failure. Clin Cardiol 2022;45(Suppl 1):S2-S12. doi:10.1002/clc.23842. Licensed under CC BY 4.0.. Source checked: opened (2026-11-14).

Categories by ejection fraction: 40% or lower; 41% to 49%; 50% or higher; improved (earlier 40% or lower, now above 40%, a rise of at least 10 points). Acuity is a clinical judgement: indicators are shown, nothing is concluded.

Edition note: The 2021 categories are shown as the 2021 edition. A 2026 second universal definition reportedly drops fixed cut-offs between reduced and preserved ejection fraction while keeping the improved category (summary of an openly licensed editorial; the consensus document itself was not opened). Clinical decision needed before release.

Edition note: A federal cross-check (NHLBI, 2022) describes reduced ejection fraction as below 40%, not 40% or lower: the boundary at exactly 40% differs between sources.

Agrees: nothing to do Kidney filtering rate (eGFR) over time

Kidney results 200 days apart are 60 or above (filtering rate 82.6 on 2026-04-26 and 82.6 on 2026-11-12) and the note doesn't mention kidney function.
