Idiopathic Spontaneous Coronary Artery Dissection: A Rare Cause of Acute Myocardial Infarction Successfully Treated With Conservative Management.

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
Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS) characterized by separation of the coronary arterial wall layers, leading to impaired coronary blood flow. It predominantly affects women and has been associated with triggers such as emotional stress and intense physical exertion. We report the case of a 44-year-old woman with no prior cardiovascular history who presented with acute chest pain and elevated troponin levels. Her initial electrocardiogram (ECG) was unremarkable, raising suspicion for non-ST-elevation myocardial infarction (NSTEMI). Subsequent coronary angiography revealed a spontaneous dissection of the first obtuse marginal artery (OM1). During hospitalization, the patient developed atrial fibrillation but remained hemodynamically stable and was managed conservatively. At one-year follow-up, she remained asymptomatic without recurrent angina or arrhythmias. This case highlights the importance of considering SCAD in younger patients, particularly women without traditional cardiovascular risk factors, presenting with symptoms of ACS, even when the initial ECG is non-diagnostic. Early recognition is essential to avoid delays in diagnosis and optimize management.
