Why the study?
Does the presence of a chronic total occlusion in a non-infarct-related artery increase five-year mortality in STEMI patients with multivessel disease undergoing primary PCI?
Does the presence of a chronic total occlusion in a non-infarct-related artery increase five-year mortality in STEMI patients with multivessel disease undergoing primary PCI?
The presence of a concurrent chronic total occlusion in a non-infarct-related artery is a significant predictor of long-term mortality in STEMI patients undergoing primary PCI.
CTO in a non-IRA was associated with increased five-year mortality in STEMI patients with MVD. This was consistently seen even after excluding early deaths within 30 days of the index STEMI event.
