Insights
Optimal treatment for non-culprit lesions in ST-segment elevation myocardial infarction (STEMI) with multi-vessel disease (MVD) is debated. Fractional flow reserve (FFR) may guide preventive revascularization, with clinical implications under investigation in a large trial.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Trials
Background:
- Optimal management of multi-vessel disease (MVD) in ST-segment elevation myocardial infarction (STEMI) remains controversial.
- Current guidelines often discourage treating non-infarct-related arteries during primary percutaneous coronary intervention (PCI).
- Emerging evidence suggests benefits of complete revascularization, but angiography lacks functional severity assessment for MVD.
Purpose of the Study:
- To evaluate the role of fractional flow reserve (FFR) in guiding treatment strategies for non-culprit lesions in STEMI patients with MVD.
- To determine the clinical implications of an FFR-guided approach compared to standard angiography in this patient population.
- To assess the safety and reliability of FFR measurements in the acute setting of STEMI.
Main Methods:
- A large randomized trial is currently investigating the clinical outcomes of an FFR-guided treatment strategy.
- The study compares FFR-guided revascularization with standard angiography-guided treatment in STEMI patients with MVD.
- FFR measurements are utilized to assess the functional significance of non-culprit coronary artery lesions.
Main Results:
- Reliability and safety of FFR measurements in STEMI patients with MVD have been established.
- The clinical implications of FFR-guided treatment are currently under evaluation in an ongoing randomized trial.
- Angiography alone does not provide sufficient information on the functional severity of MVD, potentially leading to overtreatment.
Conclusions:
- FFR measurements show promise as a valuable tool for guiding revascularization decisions in non-culprit lesions during STEMI.
- An FFR-guided strategy may help optimize treatment by avoiding unnecessary interventions in STEMI patients with MVD.
- Further results from the ongoing randomized trial are anticipated to clarify the definitive clinical benefits of FFR-guided therapy in STEMI.
Abstract:
In patients presenting with ST-segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD), the optimal therapy for non-culprit lesions is still a matter of debate. While guidelines discourage a concomitant treatment of infarct- and non-infarct-related arteries, recent studies document advantages of a complete (preventive) revascularization during primary percutaneous coronary intervention. Such an approach, however, may result in overtreatment, because angiography does not provide robust information about the functional severity of MVD. Fractional flow reserve (FFR) measurements can be a valuable guide for non-culprit lesions in acute myocardial infarction, but so far, only the reliability and safety of FFR measurements have been established in this setting. The clinical implications of an FFR-guided treatment strategy in STEMI patients with MVD are currently being tested in a large randomized trial.
