High-urgency heart transplantation and outcome trade-offs: early post-transplant infection and mortality.
Article in ESC heart failure, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsTo evaluate differences in post-transplant outcomes by pre-transplant urgency status, focusing on early post-transplant infection and its contribution to mortality.
methodsWe retrospectively analysed 801 adult heart transplant recipients enrolled in the Korea Organ Transplant Registry (April 2014-December 2021). Recipients were classified as Status 0 (highest urgency; n = 287) and Status 1-3 (n = 514). Outcomes included all-cause mortality, post-transplant infection, acute allograft rejection, and cardiac allograft vasculopathy (CAV) up to 5 years. Mediation, landmark, and multivariable time-dependent Cox models assessed the impact and determinants of infection.
resultsDuring 5-year follow-up, 128 recipients (16.0%) died. Status 0 recipients had higher mortality than Status 1-3 recipients (28.0% vs. 13.5%; P < .001). Infection was the leading cause of death and was more frequent in Status 0 recipients at 1 and 6 months, whereas rejection and CAV rates were similar between groups. Infection at 1, 6, and 12 months was strongly associated with mortality and mediated the association between urgency status and mortality, accounting for 47.4%, 34.9%, and 34.2% of total effect, respectively. After adjustment for pre- and post-transplant organ support, urgency status was no longer independently associated with infection risk, whereas prolonged mechanical ventilation (>24 h) remained the strongest predictor.
conclusionStatus 0 heart transplant recipients had higher mortality and early post-transplant infection risk than Status 1-3 recipients. Early infection, largely associated with greater clinical severity and prolonged mechanical ventilation, may explain the excess mortality in this high-urgency group.
