Differentiating an Athlete's Heart and Cardiomyopathy: Role of Advanced Cardiac Imaging.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAthletes can develop multifaceted adaptive cardiac remodeling with features overlapping with cardiomyopathy. Although clinical evaluation and echocardiography usually suffice in assessment, cases with uncertainty may benefit from advanced imaging to clarify the diagnosis and management. CASE SUMMARY: A 37-year-old male endurance athlete was referred after a screening coronary calcium scan incidentally revealed cardiac enlargement. Electrocardiography and echocardiography suggested exercise-induced physiological remodeling; however, cardiac magnetic resonance imaging revealed multifocal myocardial scarring concerning for cardiomyopathy. He underwent a comprehensive evaluation, was initiated on guideline-directed medical therapy, and ultimately resumed exercise through shared decision-making. DISCUSSION: Advanced cardiac imaging is valuable when distinguishing an athlete's heart from cardiomyopathy is uncertain and supports individualized management decisions regarding safe exercise participation. TAKE-HOME MESSAGES: Distinguishing physiological remodeling from cardiomyopathy in athletes can be challenging. Multimodality imaging can provide important diagnostic insights and guide individualized management, but its use should be judicious and findings should be interpreted with caution.
