Clinical features of non-compaction cardiomyopathy across age groups: a retrospective study of 415 patients.

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
backgroundNon-compaction cardiomyopathy (NCM) is a rare inherited cardiac disorder associated with adverse cardiovascular outcomes, including heart failure, arrhythmias and sudden cardiac death. Currently, the clinical manifestations of NCM lack comprehensive characterisation across different age groups in large-scale studies. This investigation aims to systematically analyse the clinical characteristics of patients with NCM across various age demographics.
methodsA retrospective analysis was conducted on 415 patients with NCM treated at the Guangdong Institute of Cardiovascular Disease from January 2013 to January 2023. We comprehensively collected and analysed clinical data, including presenting symptoms, arrhythmia patterns, echocardiographic parameters and cardiac magnetic resonance imaging findings.
resultsThe study cohort (n=415) was stratified into three age groups: infants (0-1 year, n=169), children/adolescents (1-18 years, n=149) and adults (>18 years, n=97). Heart failure was the predominant clinical manifestation across the entire cohort, affecting 112 patients (27%). Notably, heart failure was most prevalent in adult patients (54.6%, n=53), while cardiac murmur was the primary presenting symptom in both infant and child/adolescent groups (19.5%, n=33 and 17.4%, n=26, respectively). Across all age groups, patients with NCM with concurrent mitral regurgitation (MR) demonstrated significantly reduced left ventricular ejection fraction and fractional shortening compared with those without valvular disease (p<0.05). Additionally, left ventricular end-systolic diameter (LVESD) and end-diastolic diameter (LVEDD) were significantly increased in patients with MR (p<0.05). A significant correlation was observed between both LVESD and LVEDD measurements and MR area in patients with NCM (p<0.05).
conclusionPatients with NCM with concomitant MR consistently exhibited left ventricular dilatation and systolic dysfunction across all age groups. Significant age-related variations were observed in clinical presentations, arrhythmia patterns and the prevalence of congenital and valvular heart disease. Understanding these age-specific clinical characteristics is crucial for accurate diagnosis, optimal therapeutic management and future research directions in NCM.
