Because of its low cost, safety, diagnostic and prognostic capabilities, and lack of radiation exposure, ESE should be considered as a first-line technique for patients with suspected or confirmed CAD. It is the first indication for patients with resting ECG abnormalities and for those with inconclusive exercise ECG test results. In addition, ESE may be a useful alternative to conventional exercise ECG testing in centers where facilities and resources allow. The need for exhaustive training should not be a limitation for a technique that adds significantly to the decision-making process for patients with known or suspected CAD.
