Doctors often need to decide during a procedure whether to open a blocked heart artery. Usually, they use a tiny pressure wire to measure blood flow, but this can be complex. A study of 401 patients across 13 centers looked at an alternative: using images from the angiography itself to guide these decisions.
The results showed that the image-based method was not inferior to the traditional wire-based method for determining which arteries needed treatment. While the image-based group had a slightly higher revascularization rate of 41.4% compared to 37.9% in the wire-based group, the difference was small. Both methods were effective at identifying patients who needed intervention.
At the one-year mark, both groups showed similar rates of major heart events, such as heart attacks or death. While this new method could be a more practical, wire-free option for doctors, researchers note that larger studies are still needed to confirm these findings and ensure it can fully replace current standards.
