GUIDELINES FOR CARDIOVASCULAR STRESS TESTING AND STRESS ECHO.
In order to provide economic quality healthcare and avoid the need for multiple tests, physicians should initially use the testing modality most specific to the needs of the individual patient. Stress tests by multiple modalities (e.g., echocardiography, SPECT) for the same clinical event are covered only if the first stress testing modality was inconclusive or uninterpretable. A stress test evaluates heart action during physical or pharmacological stress to test cardiac reaction to increased demand for oxygen. It provides important diagnostic information that cannot be obtained from a resting electrocardiogram or echocardiogram alone. The preferred method of stress involves either bicycle or treadmill, symptom-limited, exercise testing. If the patient is unable to perform adequate exercise, pharmacological stress becomes the preferred method. Unless complications that are not perceived by the patient develop, the test continues until the patient reaches his/her target heart rate or experiences chest pain or fatigue. Indications for Stress Test Class I Indications are those "conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective". Class II Indications are those "conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a procedure or treatment" Class IIa Are those indications for which the "weight of evidence/opinion is in favor of usefulness/efficacy".
