Clinical value and cost effectiveness of FFR-CT in guiding revascularization and predicting major adverse cardiac...

Area of Science:

• Cardiology
• Medical Imaging
• Health Economics

Background:

• Coronary artery disease (CAD) management relies on accurate assessment of lesion severity.
• Computed Tomography Fractional Flow Reserve (FFR-CT) is an emerging non-invasive tool for evaluating hemodynamic significance of coronary stenoses.
• Current clinical guidelines advocate for FFR-CT in select patient populations.

Purpose of the Study:

• To evaluate the clinical utility of FFR-CT in guiding revascularization decisions.
• To assess FFR-CT's predictive value for major adverse cardiac events (MACE).
• To conduct a cost-effectiveness analysis of FFR-CT in patients with low-to-moderate risk CAD.

Main Methods:

• A systematic review and meta-analysis of 15 studies involving patients with suspected or known CAD.
• Outcomes analyzed included revascularization rates and MACE occurrence, stratified by FFR-CT results (≤0.8 vs. >0.8).
• A systematic review of FFR-CT costs was performed, considering healthcare cost variations and follow-up duration.

Main Results:

• Lower revascularization rates were observed in patients with FFR-CT >0.8 (5.8%) compared to those with FFR-CT ≤0.8 (41.4%).
• FFR-CT negative patients experienced fewer MACE (0.9%) than FFR-CT positive patients (2.6%).
• Cost analysis indicated potential healthcare savings, though heterogeneity in results was noted due to cost disparities and limited long-term data.

Conclusions:

• FFR-CT demonstrates significant value in predicting MACE and identifying patients who would benefit from revascularization.
• The technology holds potential for improving patient outcomes and reducing healthcare expenditures.
• FFR-CT's effectiveness in guiding unplanned revascularization was not established, necessitating further large-scale clinical trials.
