Insights
Fractional flow reserve (FFR) measurement provides objective evidence of ischemia, improving revascularization decisions for coronary artery disease. FFR-guided strategies are more effective than angiography alone.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
- Diagnostic imaging
Background:
- Coronary artery stenosis revascularization decisions often rely on angiography.
- Angiography alone has poor correlation with the functional significance of coronary lesions.
- Objective evidence of ischemia is crucial for guiding revascularization.
Purpose of the Study:
- To highlight the importance of objective ischemia evidence in revascularization decisions.
- To introduce Fractional Flow Reserve (FFR) as a key diagnostic parameter.
- To compare FFR-guided versus angiography-guided revascularization strategies.
Main Methods:
- Measurement of Fractional Flow Reserve (FFR) during invasive procedures.
- Assessment of coronary stenosis functional significance using FFR.
- Comparison of clinical outcomes between FFR-guided and angiography-guided strategies.
Main Results:
- FFR provides a reliable assessment of the functional significance of coronary stenosis.
- FFR-guided revascularization strategies demonstrate superior effectiveness compared to angiography-guided approaches.
- Emerging FFR-based technologies are poised for clinical integration.
Conclusions:
- Revascularization for coronary artery stenosis requires objective ischemia assessment.
- FFR is a valuable tool for functional assessment of coronary lesions.
- FFR-guided strategies offer improved outcomes in patients with coronary artery disease.
Abstract:
Revascularization of coronary artery stenosis should be based on the objective evidence of ischemia. It is common practice for physicians to make decisions on revascularization in the cardiac catheterization laboratory based on the results of angiography, despite the fact that angiographic information does not correlate well with the functional significance of a coronary lesion. Fractional flow reserve (FFR) is a physiologic parameter which can be measured easily during the invasive procedure and can assess the functional significance of coronary stenosis. FFR-guided revascularization strategy is reported to be more effective than angiography-guided strategy in patients with coronary artery disease. Moreover, novel technologies based on FFR have been developed and will soon be incorporated into clinical practice.
