Temporal changes in coronary artery calcium in heart transplantation patients.
Article in European radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesCoronary artery calcium (CAC) scoring is a well-established marker of atherosclerotic burden in the general population. Limited research has examined CAC progression and clinical implications in heart transplant (HT) recipients. We evaluated CAC progression in HT patients during long-term follow-up. MATERIALS AND
methodsWe included adult HT recipients (≥ 5 years post-HT) from a retrospective single-center cohort undergoing annual cardiac CT with ≥ 4 years of follow-up. CAC scores were assessed using non-contrast CT. Patients were classified into two groups: no CAC progression (CAC = 0 across all CT scans) or any increase in CAC during follow-up. Generalized linear mixed models evaluated temporal changes in CAC; logistic regression identified variables associated with CAC progression.
resultsAmong 116 patients (median age at baseline CT: 52 [38-63] years, 62% male), 65 showed CAC progression. From baseline to final CT, the proportion of patients with cardiac allograft vasculopathy (CAV) score 0 declined (90-83%), while CAV 1 and 3 increased (3-6%; 8-11%). CAC scores showed an annual increase in Ln(CAC + 1) of 0.4 (95% CI: 0.4-0.5; p < 0.001), corresponding to a 55% relative yearly increase. Significant interactions were found with recipient age at baseline CT (p = 0.008), donor heart age (p < 0.001), sex (p = 0.024), and recipient ischemic cardiomyopathy (p < 0.001). Only donor heart age was independently associated with CAC progression (p < 0.001).
conclusionCAC progression is common post-HT, with donor heart age showing the strongest association. Younger recipient and donor heart age, male sex, and ischemic cardiomyopathy were associated with faster CAC progression, suggesting the need for closer surveillance and more aggressive cardiovascular management. KEY POINTS: Question Longitudinal changes in CAC score were assessed in HT recipients to provide insights into cardiovascular risk and disease progression. Findings Over half of HT recipients showed CAC progression, which was significantly associated with donor age. Recipient age, sex, and primary diagnosis influenced progression rate. Clinical relevance Routine CAC monitoring may help identify patients at higher risk of cardiovascular events after heart transplantation, allowing for closer surveillance and more aggressive cardiovascular management, which in turn might improve long-term outcomes.
