Spontaneous Coronary Artery Dissection Beyond the Typical Demographic: Multivessel Involvement in a Male Patient.
Article in Cureus, 2025. 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
Spontaneous coronary artery dissection (SCAD) is an uncommon but increasingly recognized cause of acute myocardial infarction, predominantly affecting younger women without traditional atherosclerotic risk factors. The underlying pathophysiology remains incompletely understood and is thought to involve a complex interplay between arterial wall vulnerability and precipitating stressors. Moreover, challenges persist in achieving timely diagnosis and defining optimal management strategies. Occurrence of SCAD in men is particularly rare, often leading to diagnostic uncertainty and potential delays in appropriate management. We report the case of a 43-year-old man with a history of hypertension and obesity who presented with a non-ST-elevation myocardial infarction (NSTEMI). Given his risk profile, an atherosclerotic aetiology was initially presumed. However, coronary angiography demonstrated distal left anterior descending (LAD) artery tapering with an appearance that was thought to be consistent with SCAD. Owing to his atypical demographic for SCAD, this angiographic impression generated a diagnostic dilemma, prompting further evaluation with cardiac magnetic resonance imaging (CMR), which revealed a multivessel infarction pattern. An interval repeat angiogram later demonstrated evolving features of healing SCAD in both the LAD artery and right coronary artery, confirming the diagnosis of multivessel SCAD. Although intracoronary imaging would have been ideal to enhance diagnostic clarity, it was not performed due to the distal location of the suspected SCAD lesions and variable operator experience with intracoronary imaging. This case underscores the importance of considering SCAD even in atypical demographics such as male patients, where preconceived diagnostic assumptions may delay recognition. Greater awareness of its variable angiographic appearance and clinical patterns can help reduce diagnostic uncertainty and improve timely management.
