The influence of preexisting coronary artery disease on long-term follow up and neurological outcome in patients receiving out of hospital extracorporeal membrane oxygenation.

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
Background: Pre-hospital extracorporeal cardiopulmonary resuscitation (ECPR) in out-of-hospital cardiac arrest is costly and resource-intensive. Low survival rates raise questions concerning efficacy of ECPR. We aimed to analyze survival and neurological outcome of these patients and the influence of underlying coronary artery disease as well as shockable heart rhythm leading to resuscitation. Methods: Retrospective analysis of our ECMO database revealed 94 patients receiving ECPR for out-of-hospital cardiac arrest from September 2009 to May 2023. After exclusion of patients with pulmonary embolism, drowning or intoxication as confounders, 58 patients remained. Patients were divided into 2 groups depending on underlying coronary artery disease and initial heart rhythm. Primary outcome was survival to discharge and long-term survival, secondary outcome was neurological capacity analyzed with the cerebral performance category score (CPC). Results: 26 patients (44.8 %) survived to discharge; 6 patients died during a median follow-up time of 1057.5 days. There was no significant difference concerning survival to discharge between the groups. Numerically, more patients with shockable rhythm and without coronary artery disease survived. Kaplan-Meier analysis revealed a survival benefit for patients with shockable rhythm without coronary artery disease ( Conclusion: Though mortality in ECPR patients remains high with 55.2 %, long-term and neurological outcome with a CPC score of 1 is very good, especially of those with shockable rhythm and without coronary artery disease. Old age and duration of cardiopulmonary resuscitation pre-ECMO impair neurological outcome. Thus, on-site ECMO cannulation should be endorsed.
