Patient-Reported Health Status Among Patients With Heart Failure With Improved Ejection Fraction.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe prevalence of heart failure with improved ejection fraction (HFimpEF) is growing. The association of ejection fraction (EF) recovery and changes in health status has not been previously reported. We aimed to characterize patient-reported health status among patients with HFimpEF, heart failure with reduced ejection fraction, and heart failure with midrange (HFmrEF) or preserved ejection fraction (HFpEF).
methodsWe identified patients with heart failure with 2 clinic visits, who completed a Kansas City Cardiomyopathy Questionnaire-12 from August 2020 to October 2023. HFimpEF was defined as most recent EF >40% from a preceding echocardiogram ≥30 days prior with EF ≤40%. We analyzed Kansas City Cardiomyopathy Questionnaire-12 Overall Summary Score across EF classifications with and without adjustment for patient characteristics via multivariable linear regression. We calculated the
resultsA total of 2519 patients were included, of which 18.7% had HFimpEF, 55.7% had HFmrEF/HFpEF, and 25.6% had HFrEF. Patients with HFimpEF were less likely to be women compared with patients with HFmrEF/HFpEF (41% versus 58%,
conclusionsDespite improvement in EF, patients with HFimpEF continue to have impaired health status similar to HFpEF. Further research is needed to understand and improve health status among patients with HFimpEF.
