The relationship between serum Lumican levels and myocardial fibrosis in patients with hypertrophic 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
objectiveHypertrophic cardiomyopathy (HCM) is the leading cause of sudden cardiac death in young individuals. Lumican, is an indicator of fibrosis. We aimed to evaluate the relation between serum Lumican levels and presence and extent of myocardial fibrosis in HCM.
methodsThe patients diagnosed with HCM between June 2022 and March 2023 were enrolled consecutively in this prospective study. Age and gender-matched healthy individuals formed control group. Two groups were generated according to extent of late gadolinium enhancement (LGE) in HCM patients.
resultsA total of 114 patients were enrolled. Serum Lumican, NT-proBNP levels and maximum wall thickness were revealed as independent risk factors associated with LGE. A cut-off value of 9.06 for Lumican was associated with 67.8% sensitivity and 65.5% specificity in prediction of LGE.
conclusionMyocardial fibrosis is one of the important mechanisms in HCM pathophysiology. LGE on cardiac magnetic resonance imaging allows comprehensive evaluation of myocardial fibrosis, the support of diagnosis with a biomarker would be beneficial in clinical practice. Our study revealed that serum Lumican level is an independent predictor of severe LGE in HCM patients. Further studies with larger patient numbers may clarify the importance of Lumican in HCM pathophysiology.
