Myocardial Bridging With Left Ventricular Hypertrophy: A Case of Exercise-Induced Cardiac Arrest With Coronary Spasm.

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
backgroundA 17-year-old male athlete experienced out-of-hospital cardiac arrest due to ventricular fibrillation during exercise. Myocardial bridging (MB) and vasospasm were identified as potential contributors to the event. CASE SUMMARY: Initial imaging revealed MB of the mid-left anterior descending artery embedded within hypertrophic myocardium. Physiological assessment demonstrated significant ischemia, and acetylcholine provocation testing induced epicardial spasm, confirming MB-induced ischemia with vasospasm. Fluorodeoxyglucose positron emission tomography showed increased tracer uptake, initially suggesting malignancy, but histopathology attributed this to ischemia-related metabolic changes. The patient underwent surgical unroofing with intraoperative confirmation of arterial decompression. Postoperatively, he was treated with diltiazem and bisoprolol. DISCUSSION: This case underscores the interplay between MB and vasospasm in exercise-induced cardiac arrest and highlights surgical unroofing as a definitive treatment. TAKE-HOME MESSAGES: MB can contribute to life-threatening arrhythmias, particularly when complicated by vasospasm. Surgical unroofing with targeted medical therapy may optimize outcomes.
