Implication
Randomized trial compares iFR and FFR guidance for PCI outcomes in patients with angina, suggesting iFR is a viable alternative.
Key Points
- To evaluate the effectiveness of iFR-guided versus FFR-guided strategies in reducing major adverse cardiac events in patients with stable angina or acute coronary syndrome.
- Randomized trial comparing iFR and FFR-guided revascularization strategies.
- Follow-up duration of 12 months.
- ClinicalTrials.gov number NCT02166736.
- iFR-guided revascularization showed a noninferior rate of major adverse cardiac events compared to FFR at 12 months (exact rates not provided).
- Both guidance methods were effective in managing patients with stable angina or acute coronary syndrome.
