12. We recommend against performing preoperative pharmacological stress echocardiography to enhance perioperative cardiac risk estimation (Strong Recommendation; Low-Quality Evidence).
13. We recommend against performing preoperative pharmacological stress radionuclide imaging to enhance perioperative cardiac risk estimation (Strong Recommendation; Moderate-Quality Evidence).

The panel believed that the cost and potential delays associated with these stress tests should be taken into account because of the absence of evidence of an overall absolute net improvement in risk reclassification.
