Altered Immune Profiles in Non-Failing Heart Donors With Induced Long QT Syndrome: A Potential Risk Factor for Cardiac Allograft Vasculopathy.
Article in Clinical transplantation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionCardiac allograft vasculopathy (CAV) develops more aggressively in recipients of hearts from brain-dead (BD) donors with induced long QT syndrome (iLQTS), yet the underlying mechanisms remain poorly understood. In this study, we employ a multi-omics and experimental framework to explore the role of neuro-immune interactions in non-failing donor hearts affected by iLQTS.
methodsSingle-nuclei RNA sequencing (snRNA-seq) compared four iLQTS and four non-arrhythmic non-failing donor hearts. Pathway enrichment and cell-cell communication were assessed. Plasma proteome data from BD donors and neuronal differentially expressed (DE) genes were integrated via Omicsnet. Human BD donor transcriptomes data were analyzed for immune correlation.
resultsILQTS hearts showed elevated T/mast cells and upregulated leukocyte migration/focal adhesion pathways. Neuronal signaling (NGF, HSPG) and adhesion molecules (ITGB1, LAMININ) drove immune trafficking. Integrative proteomics identified ITGB1 as a central hub linking neuronal DE genes to BD-associated plasma proteins. Human validation linked activated CD4
conclusionsNeuro-immune dysregulation and integrin signaling related T cell activation underlie iLQTS-related heart donors. Targeting neuronal-integrin crosstalk may reduce CAV progression and improve transplant outcomes.
