Functional Assessment in Elderly MI Patients With Multivessel Disease - FIRE
Contribution To Literature:
The FIRE trial showed that physiology-guided complete revascularization reduces major adverse cardiac events compared with culprit-only revascularization.
Description:
The goal of the trial was to evaluate multivessel revascularization guided by coronary physiology compared with culprit-only revascularization among elderly patients with acute myocardial infarction (MI) and multivessel coronary artery disease (CAD).
Study Design
- Randomized
- Parallel
- Open-label
Patients with acute MI and multivessel CAD were randomized to multivessel revascularization guided by coronary physiology (n = 720) vs. culprit-only revascularization (n = 725).
- Total number of enrollees: 1,445
- Duration of follow-up: 12 months
- Mean patient age: 80 years
- Percentage female: 37%
- Percentage with diabetes: 32%
Inclusion criteria:
- ≥75 years of age
- ST-segment elevation myocardial infarction (STEMI) or NSTEMI
- Successful percutaneous coronary intervention (PCI) of culprit lesion
Exclusion criteria:
- Unclear culprit lesion
- Life expectancy <1 year
- Prior coronary artery bypass grafting (CABG)
Principal Findings:
The primary outcome, death, MI, stroke, or ischemia-driven revascularization at 12 months, was 15.7% in the physiology-guided complete revascularization group vs. 21.0% in the culprit-lesion only group (p < 0.05).
Secondary outcomes:
- Death or MI: 8.9% in the physiology-guided complete revascularization group vs. 13.5% in the culprit-lesion only group (p < 0.05)
- Acute kidney injury, stroke, or major bleeding: 22.5% in the physiology-guided complete revascularization group vs. 20.4% in the culprit-lesion only group (p = not significant)
Interpretation:
Among elderly patients with acute MI, physiology-guided complete revascularization improves outcomes compared with culprit-lesion only revascularization. The incidence of acute kidney injury, stroke, or major bleeding was similar between the treatment groups. Multiple trials now support a strategy of complete revascularization among patients with acute coronary syndrome and multivessel CAD.
