First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a new stress echocardiography method using regadenoson and atropine to diagnose coronary artery disease. It involved 45 adults scheduled for cardiac catheterization. The goal was to see if this faster, radiation-free approach could accurately detect significant blockages compared to standard angiography.
