Left Main Spontaneous Coronary Artery Dissection Complicated by Cardiogenic Shock.

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
objectiveTo review a case of left main spontaneous coronary artery dissection (SCAD) complicated by pulseless ventricular tachycardia arrest and cardiogenic shock in a 58-year-old woman without pre-existing cardiovascular risk factors, presenting as non-ST-segment elevation myocardial infarction. KEY STEPS: Catheterization with pulmonary artery catheter placement was crucial in revealing left main SCAD with severe cardiogenic shock (Society for Cardiovascular Angiography & Interventions stage D). The patient required initiation of mechanical support with Impella-supported percutaneous coronary intervention with a drug-eluting stent to the left main coronary artery. Afterward, she had full recovery and was weaned off mechanical and vasoactive support. POTENTIAL PITFALLS: While many SCAD cases are managed conservatively with medical therapy, left main involvement often requires early revascularization and is associated with a higher risk of complications. TAKE-HOME MESSAGE: This case offers insight into the diagnostic and treatment strategies of left main SCAD and underscores the importance of early revascularization to improve outcomes.
