Prediction of ventricular arrhythmic outcomes in suspected cardiac sarcoidosis: a comparison of cardiovascular magnetic resonance phenotyping vs. societal recommendations for implantable cardioverter-defibrillator placement.
Article in European heart journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND AND
aimsImplementing societal recommendations for primary prevention implantable cardioverter-defibrillators (ICDs) in cardiac sarcoidosis requires an accurate diagnosis. However, cardiac sarcoidosis diagnostic schemes are inconsistent and often produce conflicting results. This study aimed to compare the discriminative accuracy of cardiovascular magnetic resonance imaging (CMR) phenotyping with the societal recommendations for predicting long-term ventricular arrhythmic outcomes in patients with suspected cardiac sarcoidosis, regardless of their diagnostic status.
methodsThis multicentre study included patients with histology-supported sarcoidosis who underwent CMR for suspected cardiac involvement and were ineligible for secondary prevention ICDs. The study outcome was a composite of fatal or life-threatening ventricular arrhythmias. Outcomes were compared based on eligibility for ICDs by societal recommendations and CMR phenotyping.
resultsAmong 1514 patients, 84 experienced the study outcome during a median follow-up of 4.5 years and a maximum follow-up of 10 years. The high-risk CMR phenotype was associated with higher 5- and 10-year incidences of the outcome (24.0% and 35.0%, respectively) compared with those who met societal recommendations. Patients with low-risk phenotypes had lower incidences (0.7% and 2.6%). Cardiovascular magnetic resonance imaging phenotyping outperformed societal recommendations in discriminative accuracy, with areas under the curve of 0.861 and 0.776 for 5- and 10-year outcomes, respectively. Additionally, CMR phenotyping had the highest adjusted subdistribution hazard ratio (19.8) for the study outcome.
conclusionsIn patients with suspected cardiac sarcoidosis, CMR phenotyping showed greater discriminative accuracy than societal recommendations for predicting fatal or life-threatening ventricular arrhythmias, suggesting that it may be more effective at identifying candidates for primary prevention ICDs.
