Abstract

BACKGROUND: The long-term outcomes of complete revascularization in ST-segment elevation myocardial infarction (STEMI) and multivessel disease is unknown.

OBJECTIVES: To investigate the 10-year clinical outcomes including repeated events of fractional flow reserve (FFR)-guided complete revascularization versus treatment of the infarct-related artery only in STEMI.

METHODS: This 10-year follow-up study of the DANAMI-3-PRIMULTI trial included patients with STEMI and ≥1 angiographically significant non-infarct-related lesion, randomized to FFR-guided complete revascularization or infarct-related artery only after the index procedure. As the original trial, the primary outcome was a composite of all-cause mortality, recurrent myocardial infarction, or any revascularization. Repeated events of revascularization and myocardial infarction were analyzed.

RESULTS: Of 627 included patients, 313 were randomized to infarct-related artery only and 314 to complete revascularization. After 10 years, complete revascularization reduced the risk of the primary outcome (hazard ratio 0.76 (95% confidence interval (CI), 0.60-0.94) p=0.014). In the infarct-related artery only group, 78 (25%) died vs. 74 (24%) in the complete revascularization group. Complete revascularization reduced any revascularization compared with infarct-related artery only (odds ratio. 0.62 (95% CI: 0.44-0.89)). There was no difference in recurrent myocardial infarction (odds ratio, 0.90 (95% CI, 0.60-1.35)). The mean cumulative number of events were 76/100 persons (95% CI, 66-88) in the infarct-related artery only group vs. 63 events/100 persons (95% CI, 54-73) in the complete revascularization group (absolute reduction, 13% (95% CI, -1%-28%)).

CONCLUSIONS: FFR-guided complete revascularization reduced future and repeated events compared with infarct-related artery only after 10 years. The risk was mainly driven by revascularization, with no reduction in myocardial infarctions or death.
