Can Stress Echocardiography Compete with Perfusion Scintigraphy in the Detection of Coronary Artery Disease and Cardiac Risk Assessment?

The aim of this review was to define the place of stress echocardiography in the context of perfusion scintigraphy for the detection of coronary artery disease (CAD) and the assessment of cardiac risk. Stress echocardiography has the benefits of widespread availability, relatively low cost, portability, absence of radiation, and the determination of the ischaemic threshold. However, the echocardiographic windows are variable, sometimes with poor echogenicity, and interpretation is subjective and requires an adequate learning period.
