Are the contraindications for symptom-limited exercise testing the same as those for maximal exercise testing?

Are the contraindications for symptom-limited exercise testing the same as those for maximal exercise testing?

• A. No, they are completely different.
• B. Yes—the same contraindications apply.
• C. They apply only to maximal testing.
• D. They apply only to symptom-limited testing.

Answer: (B)

The key idea is safety: the reasons you would not do an exercise test in a patient are based on risk to the patient, not on how hard you plan to push them. Whether you’re aiming for a maximal effort or a symptom-limited test, the same contraindications apply because either form could provoke a dangerous event if those conditions are present. If there is an active or high-risk condition (absolute contraindication), the test should not be performed at all. Even when a test is symptom-limited, you still screen for these safety factors and you would stop or cancel the test if a contraindication is present. In other words, the decision to test is governed by safety criteria that don’t change with the testing goal. Some guidelines also distinguish relative contraindications that warrant extra caution, but they still reflect the same overall safety boundaries.
