Which age group is specified for the Stress EKG eligibility?

• A. All ages
• B. Under 40
• C. Over 40
• D. Over 50

Answer: (C)

Stress EKG tests are most informative when the likelihood of heart disease is higher, which increases with age. The cutoff used in this context is being over 40, because around that age the pretest probability of ischemia rises and the test provides clearer diagnostic value. Younger individuals under 40 often have a lower yield and a higher chance of inconclusive or false-positive results, unless they have significant symptoms or risk factors. That’s why the specified eligibility targets those over 40, rather than all ages or a higher threshold like over 50.
