Cardiac Events after Noncardiac Surgery in Patients Undergoing Preoperative Dobutamine Stress Echocardiography: Findings From the Mayo Poce-DSE Investigators

These findings demonstrate low cardiac event rates in patients who underwent a DSE prior to noncardiac surgery. The previously accepted construct of low-, intermediate-, and high-risk surgeries based on postoperative events of <1%, 1%-5%, and >5% overestimates the actual risk in contemporary settings.
