  • substudy of the COMPLETE trial
  • stratified Cox proportional hazards model
  • core laboratory-derived modified residual SYNTAX score (R′SS)

Authors' conclusion

This exploratory analysis of the COMPLETE trial suggests that the benefit of a complete revascularization strategy in patients with ST-segment-elevation myocardial infarction and multivessel disease may be related to the extent of anatomic completeness of revascularization.

Study context

Population
Patients with ST-segment-elevation myocardial infarction and multivessel diseaseCOMPLETE trial
Participants
3,738 patients
Comparison
Degree of anatomic completeness of revascularization (R′SS=0 or R′SS>0) vs culprit-only percutaneous coronary intervention (PCI) arm as reference
Primary endpoint
First coprimary outcome: composite of cardiovascular death or new myocardial infarction

Primary result

As reported in the abstract

Each group vs culprit lesion-only PCIAdjusted hazard ratio (95% CI)
