Right atrial and right ventricular strain in patients with acute decompensated heart failure: a pilot study.
Article in Frontiers in cardiovascular 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
Aims: The aim of this study was to compare the right atrial (RAS: reservoir-R, conduit-CD, contraction-CT) and right ventricular strain (global longitudinal-RV-GS, free wall strain-RV-FWS) between patients with acute decompensation of chronic heart failure (ADHF) and a control group. Methods: This study enrolled eighteen patients admitted to our ward for ADHF. Transthoracic echocardiography (TTE) with two-dimensional speckle tracking analysis (2D ST) was performed in each patient. The cut-off value of ≤40% was used to distinguish HF with reduced (HFrEF) from HF with preserved ejection fraction (HFpEF). The control group consisted of eighteen healthy individuals with no known history of cardiovascular disease. HF patients were followed for 6-months for HF-related adverse events (cardiovascular death or HF-related hospitalisation). Results: We found that RV-GS and RV-FWS were significantly lower in ADHF in comparison with the control group (RV-GS: -15.7 ± 3.32% vs. -22.6 ± 2.26%, Conclusion: Our study demonstrated a significant difference in RAS, RV-GS and RV-FWS in patients with acute decompensation of HF in comparison with the control group, with no significant difference between the HFrEF and HFpEF subgroups. RAS predicted adverse events in a 6-month follow-up period.
