Insights
Focusing on functional revascularization, guided by fractional flow reserve, improves outcomes for multivessel coronary artery disease. Tailoring treatment to individual patients and institutional expertise is crucial for optimal results.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Outcomes
Background:
- Complete anatomical revascularization has been the traditional goal for multivessel coronary artery disease (CAD).
- Emerging evidence suggests that reducing myocardial ischemia is more critical for improving clinical outcomes than complete anatomical restoration.
- Patient outcomes are linked to addressing ischemia, reducing mortality, myocardial infarction, and angina.
Purpose of the Study:
- To challenge the traditional focus on anatomical revascularization in multivessel CAD.
- To advocate for a shift towards functional revascularization based on ischemia assessment.
- To discuss the integration of functional assessments and patient-specific factors in revascularization decisions.
Main Methods:
- Review of evidence supporting functional revascularization strategies.
- Discussion of fractional flow reserve (FFR) as a key tool for ischemia assessment.
- Consideration of myocardial viability, ischemic burden, clinical risk, and technical feasibility.
Main Results:
- Functional assessment using fractional flow reserve provides objective evidence of ischemia.
- Shifting focus from anatomical to functional revascularization may improve patient outcomes.
- Personalized treatment strategies, considering individual patient factors and institutional capabilities, are essential.
Conclusions:
- Contemporary treatment for multivessel CAD should prioritize functional revascularization over purely anatomical completeness.
- Decisions regarding lesion revascularization must incorporate myocardial viability, ischemic burden, clinical risk, and feasibility.
- Tailoring revascularization strategies to the individual patient and institutional expertise, using modern techniques and pharmacotherapy, is paramount for optimal clinical outcomes.
Abstract:
The primary objective of invasive treatment strategies for multivessel coronary artery disease is complete anatomical revascularization--traditionally considered the strongest predictor of improved clinical outcome in this setting. This concept, however, is being challenged by evidence suggesting that addressing ischemia is the key to reducing mortality, myocardial infarction, and life-limiting angina. As objective evidence of ischemia can be provided by a functional assessment on the basis of fractional flow reserve, the focus of contemporary treatment should arguably shift from anatomical to functional revascularization. Moreover, the decision to revascularize specific lesions should be made after consideration of the degree of myocardial viability, ischemic burden, overall clinical risk, and technical feasibility. Most importantly, however, the revascularization strategy should be tailored to the individual patient and the expertise of the institution, and use contemporary techniques combined with modern pharmacotherapy. This Perspectives article summarizes the data supporting contemporary functional revascularization and its applicability to real-world practice.
