Plasma CCL3 predicts adverse heart failure outcomes in patients with arrhythmogenic cardiomyopathy.

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
backgroundFibro-fatty replacement of the myocardium plays a key role in the pathogenesis of arrhythmogenic cardiomyopathy (ACM) and may be associated with progressive heart failure (HF). We aimed to investigate the characteristic of the fibro-fatty tissues of ACM patients and the plasma chemokines levels according to HF burden.
methodsThe expression level of markers for brown, beige, and white fat of fibro-fatty tissues was determined using a quantitative real-time polymerase chain reaction. Lipidomics analysis of fibro-fatty tissues (n = 10 for normal control [NC]; n = 24 for ACM patients) was conducted using LC-MS. Single-cell RNA sequencing (n = 2 for NC; n = 6 for ACM patients) was used to compare the immune environment in the myocardium. Immunostaining and enzyme-linked immunosorbent assay were used to examine the expression of CCL3 in the myocardium and plasma samples, respectively.
resultsThe expression level of beige (TBX1 and TMEM26) and brown (TNFRSF9) fat markers were higher in the fibro-fatty tissues of ACM patients compared to NC. The fibro-fatty tissues revealed a significant increased level of saturated triglycerides (TGs) in ACM patients compared with NC. Single-cell RNA sequencing revealed the obvious accumulation of proinflammatory macrophages and a high expression level of proinflammatory markers in the myocardium of ACM patients compared to NC. The expression of CCL3 in the fibro-fatty tissues was positively correlated with HF progression in patients with ACM. Plasma CCL3 levels were significantly higher in patients with ACM compared to healthy volunteer. A total of 102 patients with ACM have been followed for a median of 7.8 years, indicating that plasma CCL3 levels could successfully predict the incidence of HF and heart transplantation (HTx)/death in patients with ACM (hazard ratio = 3.122 [95% confidence interval, 1.556-6.264]). The ROC curve analysis revealed the AUC value reached 0.814 for HF and 0.756 for HTx/death.
conclusionsThe increased level of saturated TGs and CCL3 in the fibro-fatty tissues might promote HF progression in ACM patients. Plasma CCL3 levels are useful for predicting HF-related adverse events in patients with ACM, but requiring further validation in larger and independent cohorts.
