Life-Saving Management of Traumatic Coronary Artery Dissection and Acute Myocardial Infarction in a 21-Year-Old Motorcyclist: A Case Report.

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
BACKGROUND A traumatic coronary artery dissection is a rare but severe complication of chest trauma that can result in blockage of the coronary artery. The clinical symptoms can vary considerably, from asymptomatic arrhythmia to acute myocardial infarction and sudden death. This report describes a young man with coronary artery dissection following blunt chest trauma from a motorcycle accident presenting with ventricular fibrillation due to acute myocardial infarction, which was treated with percutaneous transluminal coronary angioplasty and extracorporeal membrane oxygenation. CASE REPORT We present a 21-year-old man with chest contusion from a motorcycle accident who experienced sudden collapse due to ventricular fibrillation and acute myocardial infarction. The patient was resuscitated with extracorporeal membrane oxygenation, and 12-lead electrocardiogram showed sinus tachycardia with a hyperacute T-wave and ST elevation in leads V2-V6. Percutaneous coronary intervention revealed dissection from the ostial to proximal portion of the left anterior descending artery, and traumatic coronary artery dissection was confirmed. He was successfully treated with percutaneous transluminal coronary angioplasty, in which a drug-eluting stent was inserted to enhance blood flow in the left anterior descending artery, resulting in TIMI 2 flow restoration. After 16 days of intensive care, he was discharged and was well at a 3-month follow-up. CONCLUSIONS This report describes a case with the rare association between blunt chest trauma and coronary artery dissection and highlights that coronary artery dissection can result in ST-elevation myocardial infarction. Extracorporeal membrane oxygenation can protect the patient's circulation for coronary angioplasty. Therefore, early detection and intensive resuscitation can prevent disastrous outcomes.
