Cardiac events in patients with negative maximal versus negative submaximal dobutamine echocardiograms undergoing noncardiac surgery

This study sought to evaluate the negative predictive value (NPV) of preoperative dobutamine stress echocardiography (DSE) in patients who fail to achieve target heart rate (HR) and assess the influence of resting wall motion abnormalities (WMAs) without demonstrable ischemia on perioperative events...

Description
Summary:This study sought to evaluate the negative predictive value (NPV) of preoperative dobutamine stress echocardiography (DSE) in patients who fail to achieve target heart rate (HR) and assess the influence of resting wall motion abnormalities (WMAs) without demonstrable ischemia on perioperative events. The prognostic value of a negative-submaximal DSE study before noncardiac surgery is unknown. Consecutive patients (n = 429) who underwent surgery over a three-year period, preceded by DSE, were included. We compared perioperative event rates among those without inducible ischemia according to whether or not 85% age-adjusted maximum HR was achieved, and whether WMAs were present at rest. Of 397 negative DSEs, peak HR was
