Coronary Collaterals Attenuate Chest Pain in Stable Angina: Evidence From an Invasive Placebo‑Controlled N‑of‑1 Study

By MedXY 12/02/2025

An invasive, placebo‑controlled n‑of‑1 study shows that greater coronary collateral flow is associated with higher ischemic burden but lower pain intensity during controlled coronary occlusion, helping explain the weak correlation between stenosis severity and angina symptoms.

FFR-Guided Complete Revascularization Enhances Outcomes in NSTEMI with Multivessel Disease: Insights from the SLIM Trial

By MedXY 09/01/2025

The SLIM trial demonstrates that fractional flow reserve–guided complete revascularization during the index procedure significantly reduces major adverse events at one year in patients with NSTEMI and multivessel disease, primarily by lowering repeat revascularizations.

Long-Term Comparative Outcomes of FFR vs IVUS-Guided PCI in Intermediate Coronary Stenosis: Insights from the FLAVOUR Trial Extended Follow-Up

By MedXY 08/22/2025

The FLAVOUR trial's extended 6.3-year follow-up shows equivalent long-term outcomes for FFR- and IVUS-guided PCI strategies in intermediate coronary stenosis, with FFR associated with fewer total PCIs but slight increases in late revascularization.
