1 · What the graph read from it

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.

2 · The registry

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

backgroundPatients presenting with myocardial infarction and coronary artery ectasia (CAE) face an increased risk of recurrent cardiovascular events. We present a case of unrecognized CAE contributing to stent failure. CASE SUMMARY: A 52-year-old male presented with an inferior ST-segment elevation myocardial infarction and underwent percutaneous coronary intervention to the right coronary artery (RCA). Fifteen months later, he re-presented with another inferior ST-segment elevation myocardial infarction due to stent occlusion, but percutaneous coronary intervention was unsuccessful. Two weeks later, research-initiated computed coronary tomography angiography revealed a previously unrecognized large, ectatic, thrombosed RCA with unopposed stents. This prompted review of the invasive angiography leading to new appreciation of RCA calcification, supportive of CAE. DISCUSSION: CAE poses challenges in acute myocardial infarction management, increasing interventional complexity and potential need for antithrombotic therapy. TAKE-HOME MESSAGE: While ectasia may not always be appreciated on fluoroscopic imaging, its recognition is vital for guiding revascularization and secondary prevention strategies.
