Comparing Left Atrial Strain and the HFA-PEFF Score in Diagnosing Heart Failure with Preserved Ejection Fraction: A Cross-Sectional Study.
Article in Research in heart yield and translational medicine, 2025. 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
Highlights: The LA strain demonstrates diagnostic efficacy comparable to the HFA-PEFF score in diagnosing HFpEF.Integrating LA strain indices into current guidelines could enhance future HFpEF diagnostics. Background: Heart failure with preserved ejection fraction (HFpEF) has a high hospitalization rate. While recent guidelines recommend parameters like E/e' and e' velocity for diagnosis, their accuracy remains limited. Left atrial (LA) strain is a potential diagnostic parameter, yet its role in the Vietnamese population is unclear. This study aims to evaluate LA strain's diagnostic value in HFpEF among Vietnamese patients, exploring its relationship with established parameters of left ventricle diastolic function. Methods: A cross-sectional study (15/04/2022 - 01/12/2023) included 49 patients with HFpEF and 69 individuals without cardiac dysfunction. The study subjects were evaluated for LA strain and HFA-PEFF score. Diagnostic criteria for HFpEF were based on the 2021 European Society of Cardiology guidelines for diagnosing and treating acute and chronic heart failure. Results: LA strain including LA reservoir (LASr), conduit (LAScd), and contractile (LASct) functions, in the HFpEF group were 20.80% [13.30-26.50], 10.89±5.16%, and 9.08±6.18%, respectively. The control group had corresponding LASr, LAScd, and LASct values of 34.45% [31.14-38.07], 17.38±4.41%, and 17.33±5.72% (p<0.001). The area under the curve (AUC) for LASr, LAScd, LAScr, and HFA-PEFF score to diagnose HFpEF was 0.852, 0.770, 0.778, and 0.890, respectively. Comparing the AUCs for diagnosing HFpEF between LASr and HFAPEFF score, no difference was found with p=0.419. Conclusion: LASr has a diagnostic value equivalent to the HFA-PEFF score in diagnosing HFpEF and could be incorporated into the existing HFpEF diagnostic guidelines.
