Exercise Tolerance Testing
The primary goals of noninvasive testing are to aid in the diagnosis of significant CAD as well as to provide adequate risk stratification for future cardiac events including non-fatal myocardial infarction and cardiac death. Exercise tolerance testing (ETT) without imaging for many years has been an important noninvasive tool in the evaluation of patients with suspected or known coronary artery disease (CAD). The exercise tolerance test alone provides both diagnostic and risk stratification information although imaging procedures such as myocardial perfusion imaging enhance both of these endpoints. In selected patients, the ETT alone may be adequate for initial evaluation purposes. This chapter will examine the role of exercise testing as an initial strategy for the evaluation of patients with known or suspected coronary artery disease and place into perspective when ETT with imaging may be preferred.
