Does the presence of chronic total occlusion independently predict outcomes in patients resuscitated from out-of-hospital cardiac arrest with ST-segment elevation myocardial infarction?
In OHCA patients with STEMI, chronic total occlusion is a marker of higher atherosclerotic burden rather than an independent driver of early death.
In patients resuscitated from out-of-hospital cardiac arrest with ST-segment elevation myocardial infarction, chronic total occlusion is associated with increased crude death rates, but does not independently predict outcomes after adjustment. Chronic total occlusion probably reflects a higher atherosclerotic burden rather than being a direct driver of early death. The detection of chronic total occlusion remains clinically relevant for long-term management.
