Noninvasive Cardiac Testing in the Geriatric Patient

The use and interpretation of noninvasive cardiac testing in the elderly may differ from that in younger patients due to changes in disease prevalence, normal values, comorbidities, or patient and physician preferences. This paper reviews the experience with several commonly used noninvasive tests such as electrocardiography, exercise testing, and stress imaging with echocardiography or with scintigraphy in geriatric patients. Most commonly used noninvasive tests remain feasible and safe. Data suggest that exercise stress testing is feasible in many elderly patients with a good safety profile and should be considered as a first-line test due to the extra information provided by the duration and hemodynamic response to exercise. Adjunctive imaging may be particularly helpful when the electrocardiogram is uninterpretable or suspect due to underlying baseline abnormalities or when determining the extent or distribution of ischemia is felt to be important.
