Borderline Arrhythmogenic Cardiomyopathy in an Athlete: Exercise Testing May Support Clinical Decision-Making.

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
backgroundArrhythmogenic cardiomyopathy (ACM) bears a considerable risk of malignant arrhythmias and heart failure, but diagnosis in athletes can be challenging. CASE SUMMARY: We present a male 52-year-old long-distance runner with palpitations, a dilated right ventricle with apical akinesia, nonsustained ventricular tachycardia, and negative genetic testing. We performed combined stress echocardiography and cardiopulmonary exercise testing showing blunted exercise response and a decrease in right ventricular strain during exercise. Although the modified task force criteria were not met, a diagnosis of ACM based on impaired exercise response was made, and termination of high-intensity endurance and restriction to 150 minutes/wk of moderate-intensity training was recommended. DISCUSSION: The modified task force criteria are recommended for clinical decision-making, but clinical uncertainties remain in gene-elusive cases. Stress testing may complement current guidelines to unmask underlying cardiomyopathy. TAKE-HOME MESSAGE: Stress testing should be considered in athletes showing borderline features of ACM.
