Strain echocardiography for assessment of cardiac graft function following donation after circulatory death heart transplantation.
Article in JHLT open, 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
Introduction: Donation after circulatory death (DCD) heart transplantation demonstrates preserved conventional ventricular and valvular function through 1-year follow-up. However, strain imaging identifies subtle but persistent abnormalities in myocardial deformation, suggesting distinct myocardial recovery patterns and possible subclinical ischemia-related graft injury after DCD transplantation. Methods: This single-center retrospective cohort study compared DCD and Donation after Brain Death (DBD) heart transplant recipients from 2016 to 2022, at 1-, 3-, 6-, and 12-month post-transplantation. Conventional echocardiographic variables, valvular function, and speckle-tracking strain analysis, including left ventricular global longitudinal strain (LVGLS), right ventricular global longitudinal strain (RVGLS), and right ventricular free wall strain (RVFWS) were compared between DCD and DBD recipients. Multivariable linear regression, chi-squared/Fisher Exact testing, and linear mixed-effects modeling were used to evaluate longitudinal outcomes. Exploratory multivariable analyses evaluated associations between GLS and perioperative variables. Results: Fifty-one DCD and 201 DBD hearts were transplanted. Conventional echocardiography demonstrated no significant differences in LVEF or presence of valvular dysfunction at any timepoint. The treatment group-by-time interaction was not significant ( Conclusion: DCD heart transplantation demonstrates preserved conventional ventricular and valvular function through 1-year follow-up. However, strain imaging identifies subtle but persistent abnormalities in myocardial deformation, suggesting distinct myocardial recovery patterns and possible subclinical ischemia-related graft injury after DCD transplantation.
