1 · What the graph read from it

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.

2 · The registry

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 MRI (CMRI) is an important investigation in cases of unclear cause of sudden cardiac arrest (SCA). It demonstrates diagnostic utility in assessing reversibility and tissue scar burden and ultimately aids in further treatment planning.

methodsA retrospective analysis of all adult patients referred for CMRI after SCA between 2007 and 2022 by local intensive care units in our institution was performed. The patient cohort is highly selective, excluding those who did not reach the hospital, had cerebral oedema or had confirmed acute myocardial infarction as the cause of SCA. Data on clinical presentation, imaging findings and subsequent management were collected and analysed.

resultsCMRI was diagnostic in 57 of 65 patients. The most common diagnosis by CMRI was ischaemic cardiomyopathy (28.1%), followed by dilated cardiomyopathy (17.5%) and structurally normal hearts (14%). In cases of myocardial oedema, extracellular volume (ECV) was determined in 10 patients and found to be elevated in 80% after resuscitation, whereas T2 mapping was elevated in only 50% of cases. The number of examinations has increased, whereas the time to examination has decreased over the years. Additionally, CMRI findings led to changes in treatment planning.

conclusionCMRI after resuscitation is gaining increasing interest and clinical relevance as it provides additional diagnostic information that may be crucial for therapy planning. The sensitivity of ECV in detecting myocardial oedema after cardiac arrest highlights its potential utility over T2 mapping. Future studies should investigate the impact of CMRI on long-term patient outcomes and further refine its role in guiding treatment decisions.
