Summary

This study looked at people with blocked heart arteries that have side branches. Doctors placed a stent in the main artery but did not always open the side branch if blood flow was acceptable. The goal was to see if opening the side branch caused more harm or benefit. About 477 patients took part, and researchers tracked heart-related events like death, heart attack, or need for another procedure.
