The American College of Cardiology/American Heart Association (ACC/AHA) published guidelines for preoperative cardiac risk stratification in 1996. Although clinician practice may differ from the guidelines, it remains unclear whether deviation from these guidelines affects clinical outcomes. This study sought to determine if discordance between clinician practice and the ACC/AHA guidelines affects perioperative cardiac outcomes. ⋯ Conversely, clinicians ordered cardiac testing in 45 patients (7%) when not recommended by the guidelines. Patients in this group had a trend toward more cardiac complications (6.7% vs 2.4%, p = 0.09). In conclusion, the failure of clinicians to follow the ACC/AHA guidelines when perioperative testing was recommended did not result in a higher frequency of cardiac complications.
