Key Points
The study aims to explore the role of coronary collaterals in supplying blood to the heart during ischemic events.
Randomized trial evaluating patients with coronary artery disease.
Assessment of collateral vessel formation and its correlation with myocardial perfusion.
Statistical analysis performed to evaluate the effects on ischemic regions.
Increased coronary collateral formation was linked to reduced myocardial ischemia severity (p=0.01).
Patients with robust collaterals had improved perfusion rates (HR 0.75, 95% CI 0.60-0.95).
Significant regression of ischemic areas observed in the group with enhanced collateralization.
