Prospective Australasian National Bifurcation Coronary Intervention Outcomes Registry

This study is building a detailed registry to track how blocked coronary artery bifurcations — points where a heart artery splits into two branches — are treated across Australia and New Zealand. When plaque builds up at these junctions, it creates one of the trickier challenges in heart stenting procedures, and there is currently no shared database recording what techniques are used and how patients fare afterward. The registry is observational only, meaning doctors will continue treating patients exactly as they normally would. The study simply records what was done and follows up on outcomes at 72 hours, 3 months, 1 year, and 2 years to understand which approaches work best in real-world practice. You may be eligible if you are 18 or older and have significant blockage (70% or more) in a bifurcation artery, or if that artery is the culprit in a heart attack. You must be treated with drug-eluting stents. People in cardiogenic shock, with active bleeding disorders, or with allergy to antiplatelet medications are not eligible.
