Guide Extension-Facilitated Ostial Stenting (GEST) During Primary Coronary Angioplasty in a Patient With ST-Segment Elevation Myocardial Infarction: A Case Report.
Article in Cureus, 2024. 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
The guide extension-facilitated ostial stenting (GEST) technique uses a guide extension catheter (GEC) to improve stent delivery during primary coronary angioplasty (PCI). GECs are used for stent delivery into the coronary arteries of patients with difficult anatomy due to tortuosity, calcification, or chronic total occlusion (CTO) vessels. Stent and balloon placement has become challenging in patients with increasing lesion complexity due to tortuosity, vessel morphology, length of the lesion, and respiratory movements. To overcome this challenge, a guide catheter can be useful support enabling the deployment of stents in such challenging cases. We present the case of a 56-year-old male patient who was brought in by an ambulance with out-of-hospital ventricular fibrillation arrest (OOHVFA) and return of spontaneous circulation (ROSC) following successful resuscitation. The patient underwent emergency coronary angioplasty, which revealed extensive disease in the left coronary arteries and severe disease in the right coronary artery (RCA). Coronary angioplasty proved challenging secondary to vessel tortuosity, and a GEC was used for stent placement. Two stents were placed into the RCA in an overlapping fashion with the help of GEC to achieve thrombolysis in myocardial infarction (TIMI-3) flow. The patient was admitted to the intensive care unit (ICU), and echocardiography revealed mild-to-moderate left ventricular systolic dysfunction. The patient required significant inotropic support, and a computerised tomography (CT) scan of the brain showed severe hypoxic encephalopathy. The patient did not show any improvement and remained under intubation. The patient was extubated following a discussion with his family and palliative care team and passed away peacefully.
