- Residual global Murray law-based angiographic quantitative flow ratio (μQFR) was used for post-PCI risk stratification in ACS patients from the FAVOR III China trial.
- High-risk patients (residual global μQFR ≤ 2.71) had significantly higher 3-year MACE rates (21.2% vs. 10.4%) compared to low-risk patients, with an adjusted HR of 1.53.
- QFR-guided PCI in patients with low residual ischemia resulted in the best outcomes, with a 3-year MACE rate of 8.8% vs. 11.9% for angiography-guided PCI.
- The prognostic value of residual global μQFR was consistent across both QFR- and angiography-guided subgroups, supporting its utility as a robust angiographic index for long-term risk assessment.
