CARDIAC STRESS TESTS-INIDCATIONS

1. The increased demand for myocardial O 2 with exercise is the key factor in the use of exercise testing for CAD.

2. Use stress test in the detection of CAD (diagnostic tool) and in stratification of risk (prognostic tool). Diagnostic testing is most valuable when pretest probability for CAD is intermediate.

3. 2 types - exercise tolerance testing, stress image testing (with echo or perfusion scan).

4. ETT - cornerstone of diagnostic testing for ischemia, functional capacity & determining prognosis. Usually on treadmill, uses Bruce protocol.

5. The level of maximal exercise achieved on the ETT is measured in metabolic equivalents (METS).
